Tobacco product use among high school students - Youth Risk Behavior Survey, United States, 2019
Creamer MR , Everett Jones S , Gentzke AS , Jamal A , King BA . MMWR Suppl 2020 69 (1) 56-63 Tobacco product use is the leading cause of preventable disease, disability, and death in the United States. This report used data from the 2019 Youth Risk Behavior Survey to assess the following among U.S. high school students: ever use of cigarettes and electronic vapor products, current use (≥1 day during the 30 days before the survey) of tobacco products, frequent use (≥20 days during the 30 days before the survey) among current users of tobacco products, trends in use over time, and usual source of electronic vapor products among current electronic vapor product users. In 2019, a total of 50.1% of U.S. high school students had ever used electronic vapor products, and 24.1% had ever tried cigarette smoking. Current electronic vapor product use was 32.7%, current cigarette smoking was 6.0%, current cigar smoking was 5.7%, and current smokeless tobacco use was 3.8%. Approximately 36.5% of students were current users of any tobacco product, and 8.2% were current users of two or more tobacco products. Frequent use among users of individual products was 32.6% for electronic vapor products, 28.5% for smokeless tobacco, 22.2% for cigarettes, and 18.4% for cigars. Among current electronic vapor product users who were aged ≤17 years, the most commonly reported source was borrowing them from someone else (42.8%). Significant decreases occurred in current cigarette smoking (1991: 27.5%; 2019: 6.0%), cigar smoking (1997: 22.0%; 2019: 5.7%), and smokeless tobacco use (2017: 5.5%; 2019: 3.8%). However, significant increases occurred in current electronic vapor product use (2015: 24.1%; 2019: 32.7%) and any tobacco product use (2017: 19.5%; 2019: 36.5%). Although current cigarette smoking, cigar smoking, and smokeless tobacco use has decreased among high school students, the increased prevalence of electronic vapor product use among youths is concerning. Continued surveillance for all tobacco product use is warranted for guiding and evaluating public health policy at the local, state, tribal, and national levels. |
State-specific prevalence of adult tobacco product use and cigarette smoking cessation behaviors, United States, 2018-2019
Cornelius ME , Wang TW , Jamal A , Loretan CG , Willis G , Graham-Glover B , Neff L . Prev Chronic Dis 2023 20 E107 INTRODUCTION: Increasing quitting among people who smoke cigarettes is the quickest approach to reducing tobacco-related disease and death. METHODS: We analyzed data from the 2018-2019 Tobacco Use Supplement to the Current Population Survey for 137,471 adult self-respondents from all 50 US states and the District of Columbia to estimate state-specific prevalence of current tobacco product use, interest in quitting smoking, past-year quit attempts, recent successful cessation (past-year quit lasting ≥6 months), receipt of advice to quit smoking from a medical doctor, and use of cessation medications and/or counseling to quit. RESULTS: Prevalence of current any-tobacco use (use every day or some days) ranged from 10.2% in California to 29.0% in West Virginia. The percentage of adults who currently smoked cigarettes and were interested in quitting ranged from 68.2% in Alabama to 87.5% in Connecticut; made a past-year quit attempt ranged from 44.1% in Tennessee to 62.8% in Rhode Island; reported recent successful cessation ranged from 4.6% in West Virginia and Wisconsin to 10.8% in South Dakota; received advice to quit from a medical doctor ranged from 63.3% in Colorado to 86.9% in Rhode Island; and used medications and/or counseling to quit ranged from 25.5% in Nevada to 50.1% in Massachusetts. Several states with the highest cigarette smoking prevalence reported the lowest prevalence of interest in quitting, quit attempts, receipt of advice to quit, and use of counseling and/or medication, and the highest prevalence of e-cigarette, smokeless tobacco, and cigar use. CONCLUSION: Adults who smoke struggle with smoking cessation and could benefit from additional intervention. |
Tobacco product use among U.S. Middle and high school students - National Youth Tobacco Survey, 2023
Birdsey J , Cornelius M , Jamal A , Park-Lee E , Cooper MR , Wang J , Sawdey MD , Cullen KA , Neff L . MMWR Morb Mortal Wkly Rep 2023 72 (44) 1173-1182 Tobacco product use during adolescence increases the risk for lifelong nicotine addiction and adverse health consequences. CDC and the Food and Drug Administration analyzed data from the 2023 National Youth Tobacco Survey to assess tobacco product use patterns among U.S. middle school (grades 6-8) and high school (grades 9-12) students. In 2023, 10.0% of middle and high school students (2.80 million) reported current (i.e., past 30-day) use of any tobacco product. Current use of any tobacco product by high school students declined by an estimated 540,000, from 2.51 million in 2022 to 1.97 million in 2023. From 2022 to 2023, current e-cigarette use among high school students declined from 14.1% to 10.0%. Among middle and high school students, e-cigarette products were the most used tobacco product in 2023 (7.7%; 2.13 million), followed by cigarettes (1.6%), cigars (1.6%), nicotine pouches (1.5%), smokeless tobacco (1.2%), other oral nicotine products (1.2%), hookahs (1.1%), heated tobacco products (1.0%), and pipe tobacco (0.5%). Among students who had ever used an e-cigarette, 46.7% reported current use. In 2023, among students reporting current e-cigarette use, 89.4% used flavored products and 25.2% used an e-cigarette daily; the most commonly reported brands were Elf Bar, Esco Bars, Vuse, JUUL, and Mr. Fog. Given the number of middle and high school students that use tobacco products, sustained efforts to prevent initiation of tobacco product use among young persons and strategies to help young tobacco users quit are critical to reducing U.S. youth tobacco product use. |
Tobacco product use among adults - United States, 2021
Cornelius ME , Loretan CG , Jamal A , Davis Lynn BC , Mayer M , Alcantara IC , Neff L . MMWR Morb Mortal Wkly Rep 2023 72 (18) 475-483 Commercial cigarette smoking among U.S. adults has declined during the preceding 5 decades (1,2); however, tobacco product use remains the leading cause of preventable disease and death in the United States, and some populations continue to be disproportionately affected by tobacco use (1,2). To assess recent national estimates of commercial tobacco use among U.S. persons aged ≥18 years, CDC, the Food and Drug Administration (FDA), and the National Cancer Institute analyzed 2021 National Health Interview Survey (NHIS) data. In 2021, an estimated 46 million U.S. adults (18.7%) reported currently using any tobacco product, including cigarettes (11.5%), e-cigarettes (4.5%), cigars (3.5%), smokeless tobacco (2.1%), and pipes (including hookah)* (0.9%).(†) Among those who used tobacco products, 77.5% reported using combustible products (cigarettes, cigars, or pipes), and 18.1% reported using two or more tobacco products.(§) The prevalence of current use of any tobacco product use was higher among the following groups: men; persons aged <65 years; persons of non-Hispanic other races; non-Hispanic White (White) persons(¶); residents of rural (nonmetropolitan) areas; financially disadvantaged (income-to-poverty ratio = 0-1.99); lesbian, gay, or bisexual (LGB) persons; those uninsured or enrolled in Medicaid; adults whose highest level of education was a general educational development (GED) certificate; who had a disability; and who had serious psychological distress. Continued surveillance of tobacco product use, implementation of evidence-based tobacco control strategies (e.g., hard-hitting media campaigns, smoke-free policies, and tobacco price increases), conducting linguistically and culturally appropriate educational campaigns, and FDA regulation of tobacco products will aid in reducing tobacco-related disease, death, and disparities among U.S. adults (3,4). |
Disparities in current cigarette smoking among US adults with mental health conditions
Loretan CG , Wang TW , Watson CV , Jamal A . Prev Chronic Dis 2022 19 E87 INTRODUCTION: Prevalence of cigarette smoking is disproportionally high among US adults with mental health conditions. Adults with mental health conditions who smoke cigarettes are at increased risk for smoking-related illness and death compared with adults without mental health conditions. METHODS: We analyzed pooled data from the 2019 and 2020 National Survey on Drug Use and Health to provide national estimates of current cigarette smoking prevalence among US adults aged 18 years or older who reported having in the past year any mental illness, serious mental illness, mild or moderate mental illness, serious psychological distress, and/or major depressive episode (N = 19,398) and state-level estimates for any mental illness. RESULTS: Prevalence of cigarette smoking for serious mental illness was 27.2%; serious psychological distress and major depressive disorder, 25.0%; serious psychological distress, 24.5%; any mental illness, 22.8%; mild or moderate mental illness, 21.2%; and major depressive disorder, 17.6%. State-level cigarette smoking prevalence among adults with any mental illness ranged from 11.7% in Utah to 42.1% in Louisiana, with a median of 24.7%. CONCLUSION: The prevalence of current cigarette smoking is higher among adults with any mental illness, psychological distress, and major depressive disorder than among those without any mental illness, especially among adults who are non-Hispanic American Indian or Alaska Native, Hispanic, lesbian, gay, or bisexual and among those who are experiencing poverty, are uninsured, or have been arrested and booked in the past year. Continued improvement in integration of smoking cessation interventions into mental health treatment, equitable implementation of comprehensive commercial tobacco control policies, and population-specific approaches could reduce cigarette smoking among adults with mental health conditions. |
Tobacco product use among middle and high school students - United States, 2022
Park-Lee E , Ren C , Cooper M , Cornelius M , Jamal A , Cullen KA . MMWR Morb Mortal Wkly Rep 2022 71 (45) 1429-1435 Tobacco use* is the leading cause of preventable disease, disability, and death among adults in the United States (1). Youth use of tobacco products in any form is unsafe, and nearly all tobacco use begins during youth and young adulthood (2). The Food and Drug Administration (FDA) and CDC analyzed data from the 2022 National Youth Tobacco Survey (NYTS) to estimate current (past 30-day) use of eight tobacco products among U.S. middle (grades 6-8) and high school (grades 9-12) students. In 2022, approximately 11.3% of all students (representing 3.08 million persons) reported currently using any tobacco product, including 16.5% of high school and 4.5% of middle school students (2.51 million and 530,000 persons, respectively). Electronic cigarettes (e-cigarettes) were the most commonly used tobacco product among high school (14.1%; 2.14 million) and middle school (3.3%; 380,000) students. Approximately 3.7% of all students (representing 1 million persons) reported currently smoking any combustible tobacco product. Current use of any tobacco product was higher among certain population groups, including 13.5% of non-Hispanic American Indian or Alaska Native (AI/AN)(†) students; 16.0% of students identifying as lesbian, gay, or bisexual (LGB); 16.6% of students identifying as transgender; 18.3% of students reporting severe psychological distress; 12.5% of students with low family affluence; and 27.2% of students with low academic achievement. Implementation of comprehensive evidence-based tobacco control strategies, combined with FDA regulation, is important for preventing and reducing youth tobacco product use (1,2). |
Notes from the field: E-cigarette use among middle and high school students - United States, 2022
Cooper M , Park-Lee E , Ren C , Cornelius M , Jamal A , Cullen KA . MMWR Morb Mortal Wkly Rep 2022 71 (40) 1283-1285 Since 2014, e-cigarettes have been the most commonly used tobacco product among U.S. middle and high school students (1). Most e-cigarettes contain nicotine, which is highly addictive, can harm the developing adolescent brain, and can increase risk for future addiction to other drugs (2). Among middle and high school current e-cigarette users (i.e., use on ≥1 day during the past 30 days), use of disposable e-cigarette devices* increased significantly between 2019 and 2020 (3) and was the most commonly used device type reported in 2021 (4). In 2020 and 2021, approximately eight in 10 middle and high school students who used e-cigarettes reported using flavored e-cigarettes (4,5). CDC and the Food and Drug Administration (FDA) analyzed nationally representative data from the 2022 National Youth Tobacco Survey (NYTS), a school-based, cross-sectional, self-administered survey conducted during January 18–May 31, 2022,† using a web-based survey instrument and administered to U.S. middle school (grades 6–8) and high school (grades 9–12) students.§ Participating students could complete the survey whether they were physically in school or at home engaging in remote learning; 99.3% of students reported completing the survey in school. Current e-cigarette use was assessed overall and by frequency of use, device type, flavors, and brands used (any brand used and usual brand used).¶ Weighted prevalence estimates and population totals were calculated.** The NYTS study protocol was reviewed and approved by CDC’s institutional review board.†† |
Cigarette smoking among US adults with selected chronic diseases associated with smoking, 2010-2019
Loretan CG , Cornelius ME , Jamal A , Cheng YJ , Homa DM . Prev Chronic Dis 2022 19 E62 INTRODUCTION: People who smoke cigarettes are at greater risk of developing chronic diseases and related complications. Our study provides recent estimates and trends in cigarette smoking among people with respiratory and cardiovascular diseases, cancers, and diabetes. METHODS: Using data from the 2019 National Health Interview Survey, we calculated the prevalence of current and former cigarette smoking among adults aged 18 to 44 years, 45 to 64 years, and 65 years or older with chronic diseases. Those diseases were cancers associated with smoking, chronic obstructive pulmonary disease, diabetes, coronary heart disease, and/or stroke (N = 3,741). Using data from the 2010-2019 National Health Interview Surveys, we assessed trends in current cigarette smoking by chronic disease by using the National Cancer Institute's Joinpoint Regression Program. RESULTS: In 2019, current cigarette smoking prevalence among adults with chronic diseases associated with smoking ranged from 6.0% among adults aged 65 or older with diabetes to 51.9% among adults aged 18 to 44 years with 2 or more chronic diseases. During 2010 through 2019, a significant decrease occurred in current cigarette smoking among adults aged 45 to 64 years with diabetes. CONCLUSION: Overall, smoking prevalence remains high and relatively unchanged among people with chronic diseases associated with smoking, even as the overall prevalence of cigarette smoking in the US continues to decrease. The lack of progress in smoking cessation among adults with chronic diseases associated with smoking suggests that access, promotion, and integration of cessation treatment across the continuum of health care (ie, oncology, pulmonology, and cardiology settings) may be important in the success of smoking cessation in this population. |
Incidence of typhoid and paratyphoid fever in Bangladesh, Nepal, and Pakistan: results of the Surveillance for Enteric Fever in Asia Project
Garrett DO , Longley AT , Aiemjoy K , Yousafzai MT , Hemlock C , Yu AT , Vaidya K , Tamrakar D , Saha S , Bogoch II , Date K , Saha S , Islam MS , Sayeed KMI , Bern C , Shakoor S , Dehraj IF , Mehmood J , Sajib MSI , Islam M , Thobani RS , Hotwani A , Rahman N , Irfan S , Naga SR , Memon AM , Pradhan S , Iqbal K , Shrestha R , Rahman H , Hasan MM , Qazi SH , Kazi AM , Saddal NS , Jamal R , Hunzai MJ , Hossain T , Marks F , Carter AS , Seidman JC , Qamar FN , Saha SK , Andrews JR , Luby SP . Lancet Glob Health 2022 10 (7) e978-e988 BACKGROUND: Precise enteric fever disease burden data are needed to inform prevention and control measures, including the use of newly available typhoid vaccines. We established the Surveillance for Enteric Fever in Asia Project (SEAP) to inform these strategies. METHODS: From September, 2016, to September, 2019, we conducted prospective clinical surveillance for Salmonella enterica serotype Typhi (S Typhi) and Paratyphi (S Paratyphi) A, B, and C at health facilities in predetermined catchment areas in Dhaka, Bangladesh; Kathmandu and Kavrepalanchok, Nepal; and Karachi, Pakistan. Patients eligible for inclusion were outpatients with 3 or more consecutive days of fever in the last 7 days; inpatients with suspected or confirmed enteric fever; patients with blood culture-confirmed enteric fever from the hospital laboratories not captured by inpatient or outpatient enrolment and cases from the laboratory network; and patients with non-traumatic ileal perforation under surgical care. We used a hybrid surveillance model, pairing facility-based blood culture surveillance with community surveys of health-care use. Blood cultures were performed for enrolled patients. We calculated overall and age-specific typhoid and paratyphoid incidence estimates for each study site. Adjusted estimates accounted for the sensitivity of blood culture, the proportion of eligible individuals who consented and provided blood, the probability of care-seeking at a study facility, and the influence of wealth and education on care-seeking. We additionally calculated incidence of hospitalisation due to typhoid and paratyphoid. FINDINGS: A total of 34 747 patients were enrolled across 23 facilitates (six tertiary hospitals, surgical wards of two additional hospitals, and 15 laboratory network sites) during the study period. Of the 34 303 blood cultures performed on enrolled patients, 8705 (26%) were positive for typhoidal Salmonella. Adjusted incidence rates of enteric fever considered patients in the six tertiary hospitals. Adjusted incidence of S Typhi, expressed per 100 000 person-years, was 913 (95% CI 765-1095) in Dhaka. In Nepal, the adjusted typhoid incidence rates were 330 (230-480) in Kathmandu and 268 (202-362) in Kavrepalanchok. In Pakistan, the adjusted incidence rates per hospital site were 176 (144-216) and 103 (85-126). The adjusted incidence rates of paratyphoid (of which all included cases were due to S Paratyphi A) were 128 (107-154) in Bangladesh, 46 (34-62) and 81 (56-118) in the Nepal sites, and 23 (19-29) and 1 (1-1) in the Pakistan sites. Adjusted incidence of hospitalisation was high across sites, and overall, 2804 (32%) of 8705 patients with blood culture-confirmed enteric fever were hospitalised. INTERPRETATION: Across diverse communities in three south Asian countries, adjusted incidence exceeded the threshold for "high burden" of enteric fever (100 per 100 000 person-years). Incidence was highest among children, although age patterns differed across sites. The substantial disease burden identified highlights the need for control measures, including improvements to water and sanitation infrastructure and the implementation of typhoid vaccines.

Tobacco product harm perceptions among US middle and high school students, 2016-2020
Glidden E , Hawkins NA , Jamal A , Wang TW . J Adolesc Health 2022 71 (3) 364-369 PURPOSE: The aim of this study is to examine US youths' harm perceptions toward nondaily use of e-cigarettes, cigarettes, cigars, smokeless tobacco, and hookahs. METHODS: The nationally representative, cross-sectional National Youth Tobacco Survey annually assessed the following: "How much do you think people harm themselves when they [use tobacco products] some days but not every day?" Weighted estimates for 2020 were generated overall (grades 6-12) and by select demographics. Multivariable regression examined linear and quadratic changes during 2016-2020 (excluding cigars). RESULTS: In 2020, the prevalence of middle and high school students reporting "no" or "little" harm (vs. "some" or "a lot") was 20.1% for e-cigarettes, 17.4% for hookahs, 14.6% for cigars, 13.5% for smokeless tobacco, and 11.0% for cigarettes. During 2016-2020, perceptions of "no" or "little" harm decreased for e-cigarettes, increased for cigarettes and smokeless tobacco, and exhibited nonlinear changes for hookahs. DISCUSSION: Most youth are aware of tobacco product harms, but opportunities exist to educate youth about the harms of nondaily tobacco product use. |
Awareness and Use of Heated Tobacco Products Among Middle School and High School Students, United States, 2019-2020.
Puvanesarajah S , Wang T , Alexander DS , Gomez Y , Head SK , Alexandridis AA , Jamal A , Trivers K . Nicotine Tob Res 2022 24 (8) 1273-1280 PURPOSE: Heated tobacco products (HTP) heat-processed tobacco leaf into an aerosol inhaled by the user. This study assessed prevalence and correlates of HTP awareness, ever use, and current use among US middle and high school students. METHODS: Data came from the 2019 and 2020 National Youth Tobacco Survey, a cross-sectional survey of US public and private, middle and high school students. HTP awareness, ever use, and current (past 30-day) use were assessed. Weighted prevalence estimates and adjusted prevalence ratios (aPR) were assessed overall and by sex, school level, race/ethnicity, and current other tobacco product use. RESULTS: In 2019, 12.8% (3.44 million) of all students reported HTP awareness, increasing to 19.3% (5.29 million) in 2020 (p < .01). Ever [2019: 2.6% (630 000); 2020: 2.4% (620 000)] and current [2019: 1.6% (420 000); 2020: 1.4% (370 000)] HTP use did not significantly change from 2019 to 2020. Current e-cigarette users were more likely to report ever (2020 aPR = 1.79, 95% CI:1.23, 2.62) or current HTP use (2019 aPR = 5.16, 95% CI: 3.48, 7.67; 2020 aPR = 3.39, 95% CI: 2.10, 5.47) than nonusers. In both years, ever and current HTP use was more likely among current combustible (aPR range = 3.59-8.17) and smokeless tobacco product (aPR range = 2.99-4.09) users than nonusers. CONCLUSIONS: HTP awareness increased 51% among US students during 2019-2020; however, HTP use did not significantly change during this period. Students who used other tobacco products were more likely to currently use HTPs. Estimates of HTP awareness and use provided serve as a baseline as future monitoring of these products is warranted. IMPLICATIONS: Awareness of heated tobacco products (HTPs) increased among US youth from 2019 to 2020; however, HTP use did not change. These estimates of HTP awareness and use serve as a baseline for future surveillance of these products as their availability in the US increases. |
Tobacco product use among adults - United States, 2020
Cornelius ME , Loretan CG , Wang TW , Jamal A , Homa DM . MMWR Morb Mortal Wkly Rep 2022 71 (11) 397-405 Although cigarette smoking has declined over the past several decades, a diverse landscape of combustible and noncombustible tobacco products has emerged in the United States (1-4). To assess recent national estimates of commercial tobacco product use among U.S. adults aged ≥18 years, CDC analyzed data from the 2020 National Health Interview Survey (NHIS). In 2020, an estimated 47.1 million U.S. adults (19.0%) reported currently using any commercial tobacco product, including cigarettes (12.5%), e-cigarettes (3.7%), cigars (3.5%), smokeless tobacco (2.3%), and pipes* (1.1%).(†) From 2019 to 2020, the prevalence of overall tobacco product use, combustible tobacco product use, cigarettes, e-cigarettes, and use of two or more tobacco products decreased. Among those who reported current tobacco product use, 79.6% reported using combustible products (e.g., cigarettes, cigars, or pipes), and 17.3% reported using two or more tobacco products.(§) The prevalence of any current commercial tobacco product use was higher among the following groups: 1) men; 2) adults aged <65 years; 3) non-Hispanic American Indian or Alaska Native (AI/AN) adults and non-Hispanic adults categorized as of "Other" race(¶); 4) adults in rural (nonmetropolitan) areas; 5) those whose highest level of educational attainment was a general educational development certificate (GED); 6) those with an annual household income <$35,000; 7) lesbian, gay, or bisexual adults; 8) uninsured adults or those with Medicaid; 9) adults living with a disability; and 10) those who regularly had feelings of anxiety or depression. Continued monitoring of tobacco product use and tailored strategies and policies that reduce the effects of inequitable conditions could aid in reducing disparities in tobacco use (1,4). |
Tobacco product use and associated factors among middle and high school students - national youth tobacco survey, United States, 2021
Gentzke AS , Wang TW , Cornelius M , Park-Lee E , Ren C , Sawdey MD , Cullen KA , Loretan C , Jamal A , Homa DM . MMWR Surveill Summ 2022 71 (5) 1-29 PROBLEM/CONDITION: Commercial tobacco use is the leading cause of preventable disease, disability, and death in the United States. Most tobacco product use begins during adolescence. In recent years, tobacco products have evolved to include various combusted, smokeless, and electronic products. PERIOD COVERED: 2021. DESCRIPTION OF SYSTEM: The National Youth Tobacco Survey (NYTS) is an annual, cross-sectional, school-based, self-administered survey of U.S. middle school (grades 6-8) and high school (grades 9-12) students. A three-stage cluster sampling procedure is used to generate a nationally representative sample of U.S. students attending public and private schools. NYTS is the only nationally representative survey of U.S. middle and high school students that focuses exclusively on tobacco use patterns and associated factors. NYTS provides data to support the design, implementation, and evaluation of comprehensive youth tobacco use prevention and control programs and to guide tobacco regulatory activities. Since 2019, NYTS has been administered electronically via tablet computers. Because of emergency COVID-19 protocols that were in place across the United States during the 2021 NYTS fielding window (January 18-May 21, 2021), the 2021 survey was administered using a web URL to allow participation by eligible students learning under varying instructional models (in-person, distance/virtual, and hybrid). In total, 50.8% of student respondents reported completing the survey in a school building or classroom and 49.2% at home or some other place. CDC and the Food and Drug Administration (FDA) analyzed data from the 2021 NYTS to assess tobacco product use patterns and associated factors among U.S. middle and high school students. Overall, 20,413 students (out of 25,149 sampled students; student response rate: 81.2%) completed the questionnaire from 279 schools (out of 508 sampled schools; school response rate: 54.9%). The overall response rate, defined as the product of the student and school response rates, was 44.6%. The sample was weighted to represent approximately 11.97 million middle school students and 15.44 million high school students. Students with missing information about grade level were excluded from the school-level analyses (n = 135). RESULTS: In 2021, an estimated 34.0% of high school students (5.22 million) and 11.3% of middle school students (1.34 million) reported ever using a tobacco product (i.e., electronic cigarettes [e-cigarettes], cigarettes, cigars, smokeless tobacco, hookahs, pipe tobacco, heated tobacco products, nicotine pouches, and bidis [small brown cigarettes wrapped in a leaf]). Current (past 30-day) use of a tobacco product was 13.4% for high school students (2.06 million) and 4.0% for middle school students (470,000). E-cigarettes were the most commonly currently used tobacco product, cited by 11.3% of high school students (1.72 million) and 2.8% of middle school students (320,000), followed by cigarettes, cigars, smokeless tobacco, hookahs, nicotine pouches, heated tobacco products, and pipe tobacco. Current use of any tobacco product was reported by 14.2% of students identifying as lesbian, gay, or bisexual (LGB) (versus 7.9% of heterosexual); 18.9% of students identifying as transgender (versus 8.2% of not transgender); and 14.2% of students reporting severe psychological distress (versus 5.5% with no distress). Among students who currently used each respective tobacco product, frequent use (on ≥20 days of the past 30 days) ranged from 17.2% for nicotine pouches to 39.4% for e-cigarettes. Among current users of any tobacco product, 79.1% reported using a flavored tobacco product; by product, e-cigarettes were the most commonly used flavored tobacco product. Among current users of any tobacco product, the most commonly reported source of access was from a friend (32.8%). Among students who currently used e-cigarettes, 53.7% used a disposable device, 28.7% used a prefilled/refillable pod or cartridge device, 9.0% used a tank or mod system (a system that can be customized by the user), and 8.6% did not know the device type. Among students who had ever used e-cigarettes, the most common reason for first trying them was "a friend used them" (57.8%); among current e-cigarette users, the most commonly cited reason for current use was "I am feeling anxious, stressed, or depressed" (43.4%). Among all middle and high school students, 75.2% reported past-year recognition of any antitobacco public education campaign ads. Exposure to marketing or advertising for any tobacco product was reported by 75.7% of students who had contact with an assessed potential source of tobacco product advertisements or promotions (going to a convenience store, supermarket, or gas station; using the Internet; watching television or streaming services or going to the movies; or reading newspapers or magazines). Among students who reported using social media, 73.5% had ever seen e-cigarette-related content. Among all students, perceiving "no" or "little" harm from intermittent tobacco product use was highest for e-cigarettes (16.6%) and lowest for cigarettes (9.6%). Among students who currently used any tobacco product, 27.2% had experienced cravings during the past 30 days; 19.5% reported wanting to use a tobacco product within 30 minutes of waking. Moreover, 65.3% of students who currently used tobacco products were seriously thinking about quitting the use of all products, and 60.2% had stopped using all products for ≥1 day because they were trying to quit during the past 12 months. INTERPRETATION: In 2021, approximately one in 10 U.S. middle and high school students (9.3%) had used a tobacco product during the preceding 30 days. By school level, this represented more than one in eight high school students (13.4%) and approximately one in 25 middle school students (4.0%). E-cigarettes were the most commonly used tobacco product in 2021. Tobacco product use was higher among certain subpopulations, such as those identifying as LGB or transgender, or those reporting psychological distress. Importantly, approximately two thirds of students who currently used tobacco products were seriously thinking about quitting. However, factors that might continue to promote tobacco product use among U.S. youths, such as the availability of flavors, access to tobacco products, exposure to tobacco product marketing, and misperceptions about harm from tobacco product use, remained prevalent in 2021. PUBLIC HEALTH ACTION: The continued monitoring of all forms of youth tobacco product use and associated factors through surveillance efforts including NYTS is important to the development of public health policy and action at national, state, and local levels. The 2021 NYTS was successfully administered during the COVID-19 pandemic using a web URL to allow participation by eligible students learning under varying instructional models. As a result of these modifications to the fielding procedures, any comparison of results between 2021 NYTS findings with previous years, including the direct attribution of any potential changes in tobacco product use, is not possible. Parents, educators, youth advocates, and health care providers can help protect youths from the harms of tobacco products, including e-cigarettes. In addition, the comprehensive and sustained implementation of evidence-based tobacco control strategies, combined with FDA's regulation of tobacco products, is important for reducing all forms of tobacco product use among U.S. youths. |
Notes from the field: E-cigarette use among middle and high school students - National Youth Tobacco Survey, United States, 2021
Park-Lee E , Ren C , Sawdey MD , Gentzke AS , Cornelius M , Jamal A , Cullen KA . MMWR Morb Mortal Wkly Rep 2021 70 (39) 1387-1389 Since 2014, e-cigarettes have been the most commonly used tobacco product among U.S. youths (1). In 2020, an estimated 3.6 million (13.1%) U.S. middle and high school students reported using e-cigarettes within the past 30 days (current use); more than 80% of current users reported flavored e-cigarette use (2). Whereas the most commonly used device type in 2019 and 2020 was a prefilled pod or cartridge, disposable e-cigarette use increased significantly during this time among youths who currently used e-cigarettes in middle school (from 3.0% to 15.2%) and high school (from 2.4% to 26.5%) (3). CDC and the Food and Drug Administration (FDA) analyzed nationally representative data from the 2021 National Youth Tobacco Survey (NYTS), a school-based, cross-sectional, self-administered survey of U.S. middle school (grades 6–8) and high school (grades 9–12) students conducted during January 18–May 21, 2021 (20,413 students from 279 schools; overall response rate = 44.6%). Because of the ongoing COVID-19 pandemic, data were collected online to allow participation of eligible students in remote learning settings. Current e-cigarette use was assessed overall, by frequency of use, device type, flavors, and usual brand. Weighted prevalence estimates and population totals were calculated. This study was reviewed and approved by the CDC IRB © 2021. MMWR Recommendations and Reports. All rights reserved. |
Screening for colorectal cancer in the United States: correlates and time trends by type of test
Shapiro JA , Soman AV , Berkowitz Z , Fedewa SA , Sabatino SA , de Moor JS , Clarke TC , Doria-Rose VP , Breslau ES , Jamal A , Nadel MR . Cancer Epidemiol Biomarkers Prev 2021 30 (8) 1554-1565 BACKGROUND: It is strongly recommended that adults aged 50-75 years be screened for colorectal cancer (CRC). Recommended screening options include colonoscopy, sigmoidoscopy, computed tomography colonography, guaiac fecal occult blood testing (FOBT), fecal immunochemical testing (FIT), or the more recently introduced FIT-DNA (FIT in combination with a stool DNA test). CRC screening programs can benefit from knowledge of patterns of use by test type and within population subgroups. METHODS: Using 2018 National Health Interview Survey data, we examined CRC screening test use for adults aged 50-75 years (N=10,595). We also examined time trends in CRC screening test use from 2010-2018. RESULTS: In 2018, an estimated 66.9% of U.S. adults aged 50-75 years had a CRC screening test within recommended time intervals. However, the prevalence was less than 50% among those aged 50-54 years, those without a usual source of health care, those with no doctor visits in the past year, and those who were uninsured. The test types most commonly used within recommended time intervals were colonoscopy within 10 years (61.1%), FOBT or FIT in the past year (8.8%), and FIT-DNA within 3 years (2.7%). After age-standardization to the 2010 census population, the percentage up-to-date with CRC screening increased from 61.2% in 2015 to 65.3% in 2018, driven by increased use of stool testing, including FIT-DNA. CONCLUSIONS: These results show some progress, driven by a modest increase in stool testing. However, CRC testing remains low in many population subgroups. IMPACT: These results can inform efforts to achieve population CRC screening goals. |
Characteristics of e-Cigarette Use Behaviors Among US Youth, 2020
Wang TW , Gentzke AS , Neff LJ , Glidden EV , Jamal A , Park-Lee E , Ren C , Cullen KA , King BA , Hacker KA . JAMA Netw Open 2021 4 (6) e2111336 IMPORTANCE: Comprehensive surveillance of e-cigarette use behaviors among youth is important for informing strategies to address this public health epidemic. OBJECTIVE: To characterize e-cigarette use behaviors among US youth in 2020. DESIGN, SETTING, AND PARTICIPANTS: The 2020 National Youth Tobacco Survey, a nationally representative, cross-sectional, school-based survey of middle school (grades 6-8) and high school (grades 9-12) students, was conducted from January 16, 2020, to March 16, 2020. A total of 14 531 students from 180 schools participated in the 2020 survey, yielding a corresponding student-level participation rate of 87.4% and school-level participation rate of 49.9%. The overall response rate, a product of the school-level and student-level participation rates, was 43.6%. EXPOSURES: Current (past 30-day) e-cigarette use. MAIN OUTCOMES AND MEASURES: Self-reported current e-cigarette use behaviors (frequency of use, usual e-cigarette brand, and access source) by school level and flavored e-cigarette use and flavor types among current e-cigarette users by school level and device type. Prevalence estimates were weighted to account for the complex survey design. RESULTS: Overall, 14 531 students completed the survey, including 7330 female students and 7133 male students with self-reported grade level and sex. In 2020, 19.6% (95% CI, 17.2%-22.2%) of high school students and 4.7% (95% CI, 3.6%-6.0%) of middle school students reported current e-cigarette use. Among them, 38.9% (95% CI, 35.2%-42.6%) of high school users and 20.0% (95% CI, 16.0%-24.8%) of middle school users reported e-cigarette use on 20 to 30 days within the past 30 days. Among current users, JUUL was the most commonly reported usual brand (high school: 25.4%; 95% CI, 18.8%-33.4%; middle school: 35.1%; 95% CI, 27.9%-43.1%). Among current users, the most common source of obtaining e-cigarettes was from a friend (high school: 57.1%; 95% CI, 52.6%-61.4%; middle school: 58.9%; 95% CI, 51.4%-66.1%). Among current users, 84.7% (95% CI, 82.2%-86.9%) of high school students and 73.9% (95% CI, 66.9%-79.8%) of middle school students reported flavored e-cigarette use. Fruit-flavored e-cigarettes were the most commonly reported flavor among current exclusive e-cigarette users of prefilled pods or cartridges (67.3%; 95% CI, 60.9%-73.0%), disposable e-cigarettes (85.8%; 95% CI, 79.8%-90.3%), and tank-based devices (82.7%; 95% CI, 68.9%-91.1%), followed by mint-flavored e-cigarettes. CONCLUSIONS AND RELEVANCE: These results suggest that although current e-cigarette use decreased during 2019 to 2020, overall prevalence, frequent use, and flavored e-cigarette use remained high. Continued actions are warranted to prevent and reduce e-cigarette use among US youth. |
Surveillance to Track Progress Toward Polio Eradication - Worldwide, 2019-2020.
Tuma JN , Wilkinson AL , Diop OM , Jorba J , Gardner T , Snider CJ , Anand A , Ahmed J . MMWR Morb Mortal Wkly Rep 2021 70 (18) 667-673 When the Global Polio Eradication Initiative (GPEI) was established in 1988, an estimated 350,000 poliomyelitis cases were reported worldwide. In 2020, 140 wild poliovirus (WPV) cases were confirmed, representing a 99.99% reduction since 1988. WPV type 1 transmission remains endemic in only two countries (Pakistan and Afghanistan), but outbreaks of circulating vaccine-derived poliovirus (cVDPV) occurred in 33 countries during 2019-2020 (1,2). Poliovirus transmission is detected primarily through syndromic surveillance for acute flaccid paralysis (AFP) among children aged <15 years, with confirmation by laboratory testing of stool specimens. Environmental surveillance supplements AFP surveillance and plays an increasingly important role in detecting poliovirus transmission. Within 2 weeks of COVID-19 being declared a global pandemic (3), GPEI recommended continuing surveillance activities with caution and paused all polio supplementary immunization activities (4). This report summarizes surveillance performance indicators for 2019 and 2020 in 42 priority countries at high risk for poliovirus transmission and updates previous reports (5). In 2020, 48% of priority countries* in the African Region, 90% in the Eastern Mediterranean Region, and 40% in other regions met AFP surveillance performance indicators nationally. The number of priority countries rose from 40 in 2019 to 42 in 2020.(†) Analysis of 2019-2020 AFP surveillance data from 42 countries at high risk for poliovirus transmission indicates that national and subnational nonpolio AFP rates and stool specimen adequacy declined in many priority countries, particularly in the African Region, suggesting a decline in surveillance sensitivity and quality. The findings in this report can be used to guide improvements to restore a sensitive surveillance system that can track poliovirus transmission and provide evidence of interruption of transmission. |
State-Specific Prevalence of Tobacco Product Use Among US Women, Tobacco Use Supplement to the Current Population Survey, 2018-2019
Wang TW , Walton K , Reyes-Guzman C , Cullen KA , Jamal A . Prev Chronic Dis 2021 18 E36 In this study, we assessed tobacco product use among US women aged 18 years or older using data from the 2018-2019 Tobacco Use Supplement to the Current Population Survey. State-specific current use of any tobacco product (cigarettes, e-cigarettes, cigars, regular pipes, water pipes or hookah, and smokeless tobacco) ranged from 6.6% (California) to 23.1% (West Virginia); current use of 2 or more tobacco products ranged from 0.6% (New York) to 3.0% (Oklahoma). Current tobacco product use among US women differed significantly by age, education, race/ethnicity, household income, marital status, disability status, and US region. Comprehensive tobacco control strategies, including targeted interventions, can reduce tobacco use among all women. |
Disposable E-Cigarette Use among U.S. Youth - An Emerging Public Health Challenge
Wang TW , Gentzke AS , Neff LJ , Glidden EV , Jamal A , King BA , Hacker KA , Park-Lee E , Ren C , Cullen KA . N Engl J Med 2021 384 (16) 1573-1576 Previous increases in the use of electronic cigarettes (e-cigarettes) by youth were driven by multiple factors, including advertising, the use of appealing flavors, and the introduction of new devices with prefilled pods or cartridges and high nicotine levels, such as Juul.1 According to data from the National Youth Tobacco Survey (NYTS), 19.6% of high school students (3.02 million) and 4.7% of middle school students (550,000) reported current (within the preceding 30 days) e-cigarette use in 2020 — 1.8 million fewer than in 2019.2 However, e-cigarette use among youth remains prominent and the landscape of devices is evolving, both of which pose a public health challenge. We assessed the changes in device type–specific e-cigarette use during 2019 and 2020. |
Impact of COVID-19 Pandemic on Global Poliovirus Surveillance.
Zomahoun DJ , Burman AL , Snider CJ , Chauvin C , Gardner T , Lickness JS , Ahmed JA , Diop O , Gerber S , Anand A . MMWR Morb Mortal Wkly Rep 2021 69 (5152) 1648-1652 On January 30, 2020, the World Health Organization (WHO) declared coronavirus disease 2019 (COVID-19) a Public Health Emergency of International Concern (1). On March 24, 2020, the Global Polio Eradication Initiative (GPEI) suspended all polio supplementary immunization activities and recommended the continuation of polio surveillance (2). In April 2020, GPEI shared revised polio surveillance guidelines in the context of the COVID-19 pandemic, which focused on reducing the risk for transmission of SARS-CoV-2, the virus that causes COVID-19, to health care workers and communities by modifying activities that required person-to-person contact, improving hand hygiene and personal protective equipment use practices, and overcoming challenges related to movement restrictions, while continuing essential polio surveillance functions (3). GPEI assessed the impact of the COVID-19 pandemic on polio surveillance by comparing data from January to September 2019 to the same period in 2020. Globally, the number of acute flaccid paralysis (AFP) cases reported declined 33% and the mean number of days between the second stool collected and receipt by the laboratory increased by 70%. Continued analysis of AFP case reporting and stool collection is critical to ensure timely detection and response to interruptions of polio surveillance. |
Tobacco product use among middle and high school students - United States, 2020
Gentzke AS , Wang TW , Jamal A , Park-Lee E , Ren C , Cullen KA , Neff L . MMWR Morb Mortal Wkly Rep 2020 69 (50) 1881-1888 Tobacco use is the leading cause of preventable disease and death in the United States; nearly all tobacco product use begins during youth and young adulthood (1,2). CDC and the Food and Drug Administration (FDA) analyzed data from the 2019 and 2020 National Youth Tobacco Surveys (NYTS) to determine changes in the current (past 30-day) use of seven tobacco products among U.S. middle (grades 6-8) and high (grades 9-12) school students. In 2020, current use of any tobacco product was reported by 16.2% (4.47 million) of all students, including 23.6% (3.65 million) of high school and 6.7% (800,000) of middle school students. Electronic cigarettes (e-cigarettes) were the most commonly used tobacco product among high school (19.6%; 3.02 million) and middle school (4.7%; 550,000) students. From 2019 to 2020, decreases in current use of any tobacco product, any combustible tobacco product, multiple tobacco products, e-cigarettes, cigars, and smokeless tobacco occurred among high school and middle school students; these declines resulted in an estimated 1.73 million fewer current youth tobacco product users in 2020 than in 2019 (6.20 million) (3). From 2019 to 2020, no significant change occurred in the use of cigarettes, hookahs, pipe tobacco, or heated tobacco products. The comprehensive and sustained implementation of evidence-based tobacco control strategies at the national, state, and local levels, combined with tobacco product regulation by FDA, is warranted to help sustain this progress and to prevent and reduce all forms of tobacco product use among U.S. youths (1,2). |
Characteristics and correlates of recent successful cessation among adult cigarette smokers, United States, 2018
Walton K , Wang TW , Prutzman Y , Jamal A , Babb SD . Prev Chronic Dis 2020 17 E154 We assessed characteristics and correlates of recent successful cessation (quitting smoking for 6 months or longer within the past year) among US adult cigarette smokers aged 18 years or older. Estimates came from the July 2018 fielding of the 2018-2019 Tobacco Use Supplement to the Current Population Survey (N = 26,759). In 2018, 7.1% of adult smokers reported recent successful cessation. Recent successful cessation varied by certain demographic characteristics, noncigarette tobacco product use, smoke-free home rules, and receipt of advice to quit from a medical doctor. To help more smokers quit, public health practitioners can ensure that evidence-based tobacco control interventions, including barrier-free access to evidence-based cessation treatments, are reaching all tobacco users, especially those who face greater barriers to quitting. |
Tobacco product use among adults - United States, 2019
Cornelius ME , Wang TW , Jamal A , Loretan CG , Neff LJ . MMWR Morb Mortal Wkly Rep 2020 69 (46) 1736-1742 Cigarette smoking remains the leading cause of preventable disease and death in the United States (1). The prevalence of current cigarette smoking among U.S. adults has declined over the past several decades, with a prevalence of 13.7% in 2018 (2). However, a variety of combustible, noncombustible, and electronic tobacco products are available in the United States (1,3). To assess recent national estimates of tobacco product use among U.S. adults aged ≥18 years, CDC analyzed data from the 2019 National Health Interview Survey (NHIS). In 2019, an estimated 50.6 million U.S. adults (20.8%) reported currently using any tobacco product, including cigarettes (14.0%), e-cigarettes (4.5%), cigars (3.6%), smokeless tobacco (2.4%), and pipes* (1.0%).(†) Most current tobacco product users (80.5%) reported using combustible products (cigarettes, cigars, or pipes), and 18.6% reported using two or more tobacco products.(§) The prevalence of any current tobacco product use was higher among males; adults aged ≤65 years; non-Hispanic American Indian/Alaska Native (AI/AN) adults; those whose highest level of educational attainment was a General Educational Development (GED) certificate; those with an annual household income <$35,000; lesbian, gay, or bisexual (LGB) adults; uninsured adults and those with Medicaid; those with a disability; or those with mild, moderate, or severe generalized anxiety disorder. E-cigarette use was highest among adults aged 18-24 years (9.3%), with over half (56.0%) of these young adults reporting that they had never smoked cigarettes. Implementing comprehensive, evidence-based, population level interventions (e.g., tobacco price increases, comprehensive smoke-free policies, high-impact antitobacco media campaigns, and barrier-free cessation coverage), in coordination with regulation of the manufacturing, marketing, and sale of all tobacco products, can reduce tobacco-related disease and death in the United States (1,4). As part of a comprehensive approach, targeted interventions are also warranted to reach subpopulations with the highest prevalence of use, which might vary by tobacco product type. |
Feasibility of administering an electronic version of the National Youth Tobacco Survey in a classroom setting
Hu SS , Gentzke A , Jamal A , Homa D , Neff L . Prev Chronic Dis 2020 17 E20 INTRODUCTION: The National Youth Tobacco Survey (NYTS) has successfully monitored tobacco product use patterns and correlates since 1999 among US students in grades 6 through 12 using a scannable paper-and-pencil format. We conducted a study to determine the feasibility and potential benefits of administering an electronic version of the NYTS in school settings. METHODS: The pilot survey was administered by using 2 versions. Version 1 mimicked the scannable paper-and-pencil format with respect to design, formatting, and structure, but was administered on a tablet computer. Version 2 used an electronic survey design and formatting capabilities, which included programmed logic skips and tobacco product images. Chi-square and t tests were used to assess subgroup differences. Multivariable-adjusted logistic regression models were used to determine if the odds of ever and current tobacco product use differed between the 2 versions. RESULTS: In total, 2,769 students completed version 1 or version 2. Three-quarters of respondents reported a strong preference for using an electronic device to take the NYTS (74.7%). Compared with version 1, version 2 reduced the mean time to complete the survey by 15% (P < .01), reduced the number of questions students needed to answer by 30% (P < .01), and removed 1.9% of inconsistent survey responses. A significant difference was observed for ever e-cigarette use between versions 1 (22.2%) and 2 (29.5%; P < .0001). No significant differences in ever or current use were observed for other tobacco products. CONCLUSION: An electronic mode of administration is feasible and valid for conducting surveillance of tobacco product use among US youths. |
Adults' attitudes toward raising the minimum age of sale for tobacco products to 21 years, United States, 2014-2017
Gentzke AS , Glover-Kudon R , Tynan M , Jamal A . Prev Med 2020 133 106012 Raising the minimum age of sale for tobacco products to 21years (Tobacco 21) could help prevent and delay tobacco product initiation among youth. This study examined changes in U.S. adults' attitudes toward Tobacco 21 policies during 2014-2017. Data came from the 2014-2017 annual Summer Styles surveys, an Internet-based, cross-sectional survey of U.S. adults aged >/=18years, drawn from GfK's KnowledgePanel(R). Sample sizes ranged from 4107 in 2017 to 4269 in 2014. Each year, respondents were asked if they "strongly favor," "somewhat favor," "somewhat oppose," or "strongly oppose" Tobacco 21 policies. Weighted prevalence estimates of favorability (strongly or somewhat favor) were assessed each year; differences in favorability between years were assessed by chi square tests. Adjusted odds ratios (aOR) of favorability with 95% confidence intervals (CI) were calculated using logistic regression for the year 2017. Tobacco 21 policy favorability was reported by 75.0% in 2014; 72.3% in 2015; 78.4% in 2016; and 75.2% in 2017; the difference in favorability between 2014 and 2017 was not statistically significant. In 2017, lower odds of favorability toward Tobacco 21 policies were observed for current (aOR=0.49, CI=0.37-0.64) and former (aOR=0.54, CI=0.44-0.66) cigarette smokers, and current other tobacco product users (aOR=0.54, CI=0.49-0.64) than respective nonusers. Among U.S. adults, Tobacco 21 favorability has remained high since 2014, coinciding with a period of rapid state and local-level policy adoption. These results could be helpful for states and localities as they work to understand the feasibility of Tobacco 21 policies in their jurisdiction. |
Tobacco product use and associated factors among middle and high school students - United States, 2019
Wang TW , Gentzke AS , Creamer MR , Cullen KA , Holder-Hayes E , Sawdey MD , Anic GM , Portnoy DB , Hu S , Homa DM , Jamal A , Neff LJ . MMWR Surveill Summ 2019 68 (12) 1-22 PROBLEM/CONDITION: Tobacco use is the leading cause of preventable disease, disability, and death in the United States. Most tobacco product use begins during adolescence. In recent years, tobacco products have evolved to include various smoked, smokeless, and electronic products. PERIOD COVERED: 2019. DESCRIPTION OF SYSTEM: The National Youth Tobacco Survey (NYTS) is an annual, cross-sectional, school-based, self-administered survey of U.S. middle school (grades 6-8) and high school (grades 9-12) students. A three-stage cluster sampling procedure is used to generate a nationally representative sample of U.S. students attending public and private schools. NYTS is the only nationally representative survey of U.S. middle and high school students that focuses exclusively on tobacco use patterns and associated factors. NYTS is designed to provide national data on tobacco product use and has been conducted periodically during 1999-2009 and annually since 2011. Data from NYTS are used to support the design, implementation, and evaluation of comprehensive tobacco use prevention and control programs and to inform tobacco regulatory activities. Since its inception in 1999 through 2018, NYTS had been conducted via paper and pencil questionnaires. In 2019, NYTS for the first time was administered in schools using electronic data collection methods. CDC's Office on Smoking and Health, in collaboration with the U.S. Food and Drug Administration's (FDA's) Center for Tobacco Products, analyzed data from the 2019 NYTS to assess tobacco product use patterns and associated factors among U.S. middle and high school students. Overall, 19,018 questionnaires were completed and weighted to represent approximately 27.0 million students. On the basis of self-reported grade level, this included 8,837 middle school questionnaires (11.9 million students) and 10,097 high school questionnaires (15.0 million students); 84 questionnaires with missing information on grade level were excluded from school-level analyses. RESULTS: In 2019, an estimated 53.3% of high school students (8.0 million) and 24.3% of middle school students (2.9 million) reported having ever tried a tobacco product. Current (past 30-day) use of a tobacco product (i.e., electronic cigarettes [e-cigarettes], cigarettes, cigars, smokeless tobacco, hookahs, pipe tobacco, and bidis [small brown cigarettes wrapped in a leaf]) was reported by 31.2% of high school students (4.7 million) and 12.5% of middle school students (1.5 million). E-cigarettes were the most commonly cited tobacco product currently used by 27.5% of high school students (4.1 million) and 10.5% of middle school students (1.2 million), followed in order by cigars, cigarettes, smokeless tobacco, hookahs, and pipe tobacco. Tobacco product use also varied by sex and race/ethnicity. Among current users of each tobacco product, the prevalence of frequent tobacco product use (on >/=20 days of the preceding 30 days) ranged from 16.8% of cigar smokers to 34.1% of smokeless tobacco product users. Among current users of each individual tobacco product, e-cigarettes were the most commonly used flavored tobacco product (68.8% of current e-cigarette users). Among students who reported ever having tried e-cigarettes, the three most commonly selected reasons for use were "I was curious about them" (55.3%), "friend or family member used them" (30.8%), and "they are available in flavors, such as mint, candy, fruit, or chocolate" (22.4%). Among never users of each individual tobacco product, curiosity and susceptibility (a construct that can help to identify future tobacco product experimentation or use) was highest for e-cigarettes (39.1% and 45.0%, respectively) and cigarettes (37.0% and 45.9%, respectively). Overall, 86.3% of students who reported contact with an assessed potential source of tobacco product advertisements or promotions (going to a convenience store, supermarket, or gas station; using the Internet; watching television or streaming services or going to the movies; or reading newspapers or magazines) reported exposure to marketing for any tobacco product; 69.3% reported exposure to e-cigarette marketing and 81.7% reported exposure to marketing for cigarettes or other tobacco products. Among all students, perceiving no harm or little harm from intermittent tobacco product use (use on some days but not every day) was 28.2% for e-cigarettes, 16.4% for hookahs, 11.5% for smokeless tobacco products, and 9.5% for cigarettes. Among current users of any tobacco product, 24.7% reported experiencing cravings to use tobacco products during the past 30 days and 13.7% reported wanting to use a tobacco product within 30 minutes of waking. Moreover, 57.8% of current tobacco product users reported they were seriously thinking about quitting the use of all tobacco products and 57.5% reported they had stopped using all tobacco products for >/=1 day because they were trying to quit. INTERPRETATION: In 2019, approximately one in four youths (23.0%) had used a tobacco product during the past 30 days. By school level, this represented approximately three in 10 high school students (31.2%) and approximately one in eight middle school students (12.5%). Since 2014, e-cigarettes have been the most commonly used tobacco product among youths. Importantly, more than half of current youth tobacco product users reported seriously thinking about quitting all tobacco products in 2019. However, established factors of use and initiation, including the availability of flavors, exposure to tobacco product marketing, curiosity and susceptibility, and misperceptions about harm from tobacco product use, remained prevalent in 2019 and continue to promote tobacco product use among youths. PUBLIC HEALTH ACTION: The continued monitoring of all forms of youth tobacco product use and associated factors through surveillance efforts including NYTS is important to the development of public health policy and action at national, state, and community levels. Everyone, including public health professionals, health care providers, policymakers, educators, parents, and others who influence youths, can help protect youths from the harms of all tobacco products. In addition, the comprehensive and sustained implementation of evidence-based tobacco control strategies, combined with FDA's regulation of tobacco products, is important for reducing all forms of tobacco product use among U.S. youths. |
Tobacco product use and cessation indicators among adults - United States, 2018
Creamer MR , Wang TW , Babb S , Cullen KA , Day H , Willis G , Jamal A , Neff L . MMWR Morb Mortal Wkly Rep 2019 68 (45) 1013-1019 Cigarette smoking is the leading cause of preventable disease and death in the United States (1). The prevalence of adult cigarette smoking has declined in recent years to 14.0% in 2017 (2). However, an array of new tobacco products, including e-cigarettes, has entered the U.S. market (3). To assess recent national estimates of tobacco product use among U.S. adults aged >/=18 years, CDC, the Food and Drug Administration (FDA), and the National Cancer Institute analyzed data from the 2018 National Health Interview Survey (NHIS). In 2018, an estimated 49.1 million U.S. adults (19.7%) reported currently using any tobacco product, including cigarettes (13.7%), cigars (3.9%), e-cigarettes (3.2%), smokeless tobacco (2.4%), and pipes* (1.0%). Most tobacco product users (83.8%) reported using combustible products (cigarettes, cigars, or pipes), and 18.8% reported using two or more tobacco products. The prevalence of any current tobacco product use was higher in males; adults aged </=65 years; non-Hispanic American Indian/Alaska Natives; those with a General Educational Development certificate (GED); those with an annual household income <$35,000; lesbian, gay, or bisexual adults; uninsured adults; those with a disability or limitation; and those with serious psychological distress. The prevalence of e-cigarette and smokeless tobacco use increased during 2017-2018. During 2009-2018, there were significant increases in all three cigarette cessation indicators (quit attempts, recent cessation, and quit ratio). Implementing comprehensive population-based interventions in coordination with regulation of the manufacturing, marketing, and distribution of all tobacco products can reduce tobacco-related disease and death in the United States (1,4). |

Cullen KA , Gentzke AS , Sawdey MD , Chang JT , Anic GM , Wang TW , Creamer MR , Jamal A , Ambrose BK , King BA . JAMA 2019 322 (21) 2095-2103 Importance: The prevalence of e-cigarette use among US youth increased from 2011 to 2018. Continued monitoring of the prevalence of e-cigarette and other tobacco product use among youth is important to inform public health policy, planning, and regulatory efforts. Objective: To estimate the prevalence of e-cigarette use among US high school and middle school students in 2019 including frequency of use, brands used, and use of flavored products. Design, Setting, and Participants: Cross-sectional analyses of a school-based nationally representative sample of 19018 US students in grades 6 to 12 participating in the 2019 National Youth Tobacco Survey. The survey was conducted from February 15, 2019, to May 24, 2019. Main Outcomes and Measures: Self-reported current (past 30-day) e-cigarette use estimates among high school and middle school students; frequent use (>/=20 days in the past 30 days) and usual e-cigarette brand among current e-cigarette users; and use of flavored e-cigarettes and flavor types among current exclusive e-cigarette users (no use of other tobacco products) by school level and usual brand. Prevalence estimates were weighted to account for the complex sampling design. Results: The survey included 10097 high school students (mean [SD] age, 16.1 [3.0] years; 47.5% female) and 8837 middle school students (mean [SD] age, 12.7 [2.8] years; 48.7% female). The response rate was 66.3%. An estimated 27.5% (95% CI, 25.3%-29.7%) of high school students and 10.5% (95% CI, 9.4%-11.8%) of middle school students reported current e-cigarette use. Among current e-cigarette users, an estimated 34.2% (95% CI, 31.2%-37.3%) of high school students and 18.0% (95% CI, 15.2%-21.2%) of middle school students reported frequent use, and an estimated 63.6% (95% CI, 59.3%-67.8%) of high school students and 65.4% (95% CI, 60.6%-69.9%) of middle school students reported exclusive use of e-cigarettes. Among current e-cigarette users, an estimated 59.1% (95% CI, 54.8%-63.2%) of high school students and 54.1% (95% CI, 49.1%-59.0%) of middle school students reported JUUL as their usual e-cigarette brand in the past 30 days; among current e-cigarette users, 13.8% (95% CI, 12.0%-15.9%) of high school students and 16.8% (95% CI, 13.6%-20.7%) of middle school students reported not having a usual e-cigarette brand. Among current exclusive e-cigarette users, an estimated 72.2% (95% CI, 69.1%-75.1%) of high school students and 59.2% (95% CI, 54.8%-63.4%) of middle school students used flavored e-cigarettes, with fruit, menthol or mint, and candy, desserts, or other sweets being the most commonly reported flavors. Conclusions and Relevance: In 2019, the prevalence of self-reported e-cigarette use was high among high school and middle school students, with many current e-cigarette users reporting frequent use and most of the exclusive e-cigarette users reporting use of flavored e-cigarettes. |
State-specific prevalence of quit attempts among adult cigarette smokers - United States, 2011-2017
Walton K , Wang TW , Schauer GL , Hu S , McGruder HF , Jamal A , Babb S . MMWR Morb Mortal Wkly Rep 2019 68 (28) 621-626 From 1965 to 2017, the prevalence of cigarette smoking among U.S. adults aged >/=18 years decreased from 42.4% to 14.0%, in part because of increases in smoking cessation (1,2). Increasing smoking cessation can reduce smoking-related disease, death, and health care expenditures (3). Increases in cessation are driven in large part by increases in quit attempts (4). Healthy People 2020 objective 4.1 calls for increasing the proportion of U.S. adult cigarette smokers who made a past-year quit attempt to >/=80% (5). To assess state-specific trends in the prevalence of past-year quit attempts among adult cigarette smokers, CDC analyzed data from the 2011-2017 Behavioral Risk Factor Surveillance System (BRFSS) surveys for all 50 states, the District of Columbia (DC), Guam, and Puerto Rico. During 2011-2017, quit attempt prevalence increased in four states (Kansas, Louisiana, Virginia, and West Virginia), declined in two states (New York and Tennessee), and did not significantly change in the remaining 44 states, DC, and two territories. In 2017, the prevalence of past-year quit attempts ranged from 58.6% in Wisconsin to 72.3% in Guam, with a median of 65.4%. In 2017, older smokers were less likely than younger smokers to make a quit attempt in most states. Implementation of comprehensive state tobacco control programs and evidence-based tobacco control interventions, including barrier-free access to cessation treatments, can increase the number of smokers who make quit attempts and succeed in quitting (2,3). |
State-specific cessation behaviors among adult cigarette smokers - United States, 2014-2015
Wang TW , Walton K , Jamal A , Babb SD , Schecter A , Prutzman YM , King BA . Prev Chronic Dis 2019 16 E26 This study assessed state-specific smoking cessation behaviors among US adult cigarette smokers aged 18 years or older. Estimates came from the 2014-2015 Tobacco Use Supplement to the Current Population Survey (N = 163,920). Prevalence of interest in quitting ranged from 68.9% (Kentucky) to 85.7% (Connecticut); prevalence of making a quit attempt in the past year ranged from 42.7% (Delaware) to 62.1% (Alaska); prevalence of recently quitting smoking ranged from 3.9% (West Virginia) to 11.1% (District of Columbia); and prevalence of receiving quit advice from a medical doctor in the past year ranged from 59.4% (Nevada) to 81.7% (Wisconsin). These findings suggest that opportunities exist to encourage and help more smokers to quit. |
