E-cigarette use among persons with diagnosed HIV in the U.S.
Thorne SL , Caraballo RS , Tie Y , Harris NS , Shouse RL , Brooks JT . AJPM Focus 2023 2 (1) INTRODUCTION: E-cigarettes emerged in the U.S. market in the late 2000s. In 2017, E-cigarette use among U.S. adults was 2.8%, with higher use among some population groups. Limited studies have assessed E-cigarette use among persons with diagnosed HIV. The purpose of this study is to describe the national prevalence estimates of E-cigarette use among persons with diagnosed HIV by selected sociodemographic, behavioral, and clinical characteristics. METHODS: Data were collected between June 2018 and May 2019 as part of the Medical Monitoring Project, an annual cross-sectional survey that produces nationally representative estimates of behavioral and clinical characteristics of persons with diagnosed HIV in the U.S. Statistically significant differences (p<0.05) were determined using chi-square tests. Data were analyzed in 2021. RESULTS: Among persons with diagnosed HIV, 5.9% reported currently using E-cigarettes, 27.1% had ever used them but were not using them currently, and 72.9% had never used them. Current use of E-cigarettes was highest among persons with diagnosed HIV who currently smoke conventional cigarettes (11.1%), those with major depression (10.8%), those aged 25-34 years (10.5%), those who reported injectable and noninjectable drug use in the past 12 months (9.7%), those diagnosed <5 years ago (9.5%), those who self-reported sexual orientation as other (9.2%), and non-Hispanic White people (8.4%). CONCLUSIONS: Overall, findings suggest that a greater proportion of persons with diagnosed HIV used E-cigarettes than the overall U.S. adult population and that higher rates were observed among certain subgroups, including those who currently smoke cigarettes. E-cigarette use among persons with diagnosed HIV warrants continued attention because of its potential impact on HIV-related morbidity and mortality. |
Socioeconomic differences in cigarette smoking among sociodemographic groups
Garrett BE , Martell BN , Caraballo RS , King BA . Prev Chronic Dis 2019 16 E74 We examined variations in cigarette smoking by socioeconomic status (education and poverty status) in relation to population sociodemographic characteristics (age, race/ethnicity, region and sex). We analyzed data from a nationally representative sample of US adults by using combined data from the National Survey on Drug Use and Health (2011-2014). Low socioeconomic status was generally associated with increased cigarette smoking prevalence by age, race/ethnicity, and region, irrespective of sex. The only exceptions were for Asian and Hispanic women, where low educational attainment was not associated with a high prevalence of cigarette smoking, and among Hispanic men and Asian women, where there was no association between poverty status and smoking. Efforts to reach smokers of low socioeconomic status by using proven tobacco control strategies could reduce disparities in cigarette smoking and smoking-related disease and death. |
Social and physical environmental characteristics associated with adult current cigarette smoking
Caraballo RS , Rice KL , Neff LJ , Garrett BE . Prev Chronic Dis 2019 16 E71 INTRODUCTION: Our objective was to identify social and physical environmental factors associated with current cigarette smoking among adults by metropolitan county in the United States. METHODS: We linked cigarette smoking data from the 2012 Behavioral Risk Factor Surveillance System (BRFSS) Selected Metropolitan Area Risk Trends (SMART) data set to 7 social and physical environmental characteristics: county type (metropolitan designation), primary care physician density, income inequality, percentage of the population that was a racial/ethnic minority, violent crime rate, education, and percentage of county residents with low income and no health insurance, all obtained from several county data sets. Spatial regression and hierarchical logistic regression modeling were performed. RESULTS: Results showed that metropolitan counties with a high proportion of non-Hispanic white adults (P < .001), lower education levels (high school graduate or less) (P < .001), and high violent crime rates (P < .001) had a higher adult cigarette smoking prevalence than other metropolitan counties. Spatial models showed 63.3% of the variability in county cigarette smoking prevalence was explained by these 3 factors as well as county type (based on population size of the of metropolitan area), primary care physician density, and percentage of county residents with low income and no health insurance. At an individual level, results showed that as the density (population) of primary care physicians increased in a county, the odds of being a current smoker decreased (OR, 0.980; P = .02). CONCLUSION: We found a significant association between adult cigarette smoking and county social and physical environmental factors. These place-based factors, especially social environmental characteristics, may reveal tobacco-related disparities to be considered when developing strategies to reduce tobacco use. |
Lung cancer screening inconsistent with U.S. Preventive Services Task Force recommendations
Richards TB , Doria-Rose VP , Soman A , Klabunde CN , Caraballo RS , Gray SC , Houston KA , White MC . Am J Prev Med 2018 56 (1) 66-73 INTRODUCTION: Prior studies suggest overuse of nonrecommended lung cancer screening tests in U.S. community practice and underuse of recommended tests. METHODS: Data from the 2010 and 2015 National Health Interview Surveys was analyzed from 2016 to 2018. Prevalence, populations, and number of chest computed tomography (CT) and chest x-ray tests were estimated for people who did and did not meet U.S. Preventive Services Task Force (USPSTF) criteria for lung cancer screening, among people aged >/=40 years without lung cancer. RESULTS: In 2015, among those who met USPSTF criteria, 4.4% (95% CI=3.0%, 6.6%), or 360,000 (95% CI=240,000, 535,000) people reported lung cancer screening with a chest CT; and 8.5% (95% CI=6.5%, 11.1%), or 689,000 (95% CI=526,000, 898,000) people reported a chest x ray. Among those who did not meet USPSTF criteria, 2.3% (95% CI=2.0%, 2.6%), or 3,259,000 (95% CI=2,850,000, 3,724,000) people reported a chest x ray; and 1.3% (95% CI=1.1%, 1.5%), or 1,806,000 (95% CI=1,495,000, 2,173,000) people reported a chest CT. The estimated population meeting USPSTF criteria for lung cancer screening in 2015 was 8,098,000 (95% CI=7,533,000, 8,702,000), which was smaller than the 9,620,000 people (95% CI=8,960,000, 10,325,000) in 2010. CONCLUSIONS: The number of adults inappropriately screened for lung cancer greatly exceeds the number screened according to USPSTF recommendations, the prevalence of appropriate lung cancer screening is low, and the population meeting USPSTF criteria is shrinking. To realize the potential benefits of screening, better processes to appropriately triage eligible individuals to screening, plus screening with a USPSTF-recommended test, would be beneficial. |
A comprehensive examination of own- and cross-price elasticities of tobacco and nicotine replacement products in the U.S
Huang J , Gwarnicki C , Xu X , Caraballo RS , Wada R , Chaloupka FJ . Prev Med 2018 117 107-114 While much is known about the demand for cigarettes, research on the demand for non-cigarette tobacco products and the cross-price impacts among those products is limited. This study aims to comprehensively examine the own- and cross-price elasticities of demand for tobacco and nicotine replacement products (NRPs) in the U.S. We analyzed market-level quarterly data on sales and prices of 15 different types of tobacco products and NRPs from 2007 to 2014, compiled from retail store scanner data. Fixed effects models with controls were used to estimate their own-price elasticities and cross-price elasticities between cigarettes and the other 14 products. Our results show that, except for cigars, the demand for combustible tobacco products was generally elastic, with the estimated own-price elasticity >1 (10% increase in prices reduces sales by >10%). The own-price elasticities for smokeless tobacco products were smaller than those for combustible tobacco, although not always significant. The demand for electronic cigarettes and NRPs was found to be elastic. The cross-price elasticities with respect to cigarettes were positive for cigarillos, little cigars, loose tobacco, pipe tobacco, electronic cigarettes and NRPs, but only results for little cigars, loose tobacco, pipe tobacco, and dissolvable lozenges were consistently significant. Our findings suggest demand for tobacco products and NRPs was responsive to changes in their own prices. Substitutions or positive cross-price impacts between cigarettes and certain other products exist. It is important that tobacco control policies take into account both own- and cross-price impacts among tobacco products and NRTs. |
Reasons for electronic cigarette use among middle and high school students - National Youth Tobacco Survey, United States, 2016
Tsai J , Walton K , Coleman BN , Sharapova SR , Johnson SE , Kennedy SM , Caraballo RS . MMWR Morb Mortal Wkly Rep 2018 67 (6) 196-200 Electronic cigarettes (e-cigarettes) were the most commonly used tobacco product among U.S. middle school and high school students in 2016 (1). CDC and the Food and Drug Administration (FDA) analyzed data from the 2016 National Youth Tobacco Survey (NYTS) to assess self-reported reasons for e-cigarette use among U.S. middle school (grades 6-8) and high school (grades 9-12) student e-cigarette users. Among students who reported ever using e-cigarettes in 2016, the most commonly selected reasons for use were 1) use by "friend or family member" (39.0%); 2) availability of "flavors such as mint, candy, fruit, or chocolate" (31.0%); and 3) the belief that "they are less harmful than other forms of tobacco such as cigarettes" (17.1%). The least commonly selected reasons were 1) "they are easier to get than other tobacco products, such as cigarettes" (4.8%); 2) "they cost less than other tobacco products such as cigarettes" (3.2%); and 3) "famous people on TV or in movies use them" (1.5%). Availability of flavors as a reason for use was more commonly selected by high school users (32.3%) than by middle school users (26.8%). Efforts to prevent middle school and high school students from initiating the use of any tobacco product, including e-cigarettes, are important to reduce tobacco product use among U.S. youths (2). |
Quit methods used by US adult cigarette smokers, 2014-2016
Caraballo RS , Shafer PR , Patel D , Davis KC , McAfee TA . Prev Chronic Dis 2017 14 E32 To quantify the prevalence of 10 quit methods commonly used by adult cigarette smokers, we used data from a nationally representative longitudinal (2014-2016) online survey of US adult cigarette smokers (n = 15,943). Overall, 74.7% of adult current cigarette smokers used multiple quit methods during their most recent quit attempt. Giving up cigarettes all at once (65.3%) and reducing the number of cigarettes smoked (62.0%) were the most prevalent methods. Substituting some cigarettes with e-cigarettes was used by a greater percentage of smokers than the nicotine patch, nicotine gum, or other cessation aids approved by the US Food and Drug Administration. Further research into the effectiveness of e-cigarettes as a cessation aid is warranted. |
Tax avoidance and evasion: Cigarette purchases from Indian reservations among US adult smokers, 2010-2011
Wang X , Xu X , Tynan MA , Gerzoff RB , Caraballo RS , Promoff GR . Public Health Rep 2017 132 (3) 33354917703653 Excise taxes are the primary public health strategy used to increase the price of cigarettes in the United States. Rather than quitting or reducing consumption of cigarettes, some price-sensitive smokers may avoid state and local excise taxes by purchasing cigarettes from Indian reservations. The objectives of this study were to (1) provide the most recent state-specific prevalence of purchases made on Indian reservations by non-American Indians/Alaska Natives (non-AI/ANs) and (2) assess the impact of these purchases on state tax revenues. We used data from a large national and state-representative survey, the 2010-2011 Tobacco Use Supplement to the Current Population Survey, which collects self-reported measures on cigarette use and purchases. Nationwide, 3.8% of non-AI/AN smokers reported purchasing cigarettes from Indian reservations. However, in Arizona, Nevada, New Mexico, New York, Oklahoma, and Washington State, about 15% to 30% of smokers reported making such purchases, resulting in annual tax revenue losses ranging from $3.5 million (Washington State) to $292 million (New York) during 2010-2011. Strategies to reduce the sale of non- or lower-taxed cigarettes to non-AI/ANs on Indian reservations have the potential to decrease smoking prevalence and recoup lost revenue from purchases made on reservations. |
Health-related behaviors by urban-rural county classification - United States, 2013
Matthews KA , Croft JB , Liu Y , Lu H , Kanny D , Wheaton AG , Cunningham TJ , Khan LK , Caraballo RS , Holt JB , Eke PI , Giles WH . MMWR Surveill Summ 2017 66 (5) 1-8 PROBLEM/CONDITION: Persons living in rural areas are recognized as a health disparity population because the prevalence of disease and rate of premature death are higher than for the overall population of the United States. Surveillance data about health-related behaviors are rarely reported by urban-rural status, which makes comparisons difficult among persons living in metropolitan and nonmetropolitan counties. REPORTING PERIOD: 2013. DESCRIPTION OF SYSTEM: The Behavioral Risk Factor Surveillance System (BRFSS) is an ongoing, state-based, random-digit-dialed landline- and cellular-telephone survey of noninstitutionalized adults aged ≥18 years residing in the United States. BRFSS collects data on health-risk behaviors, chronic diseases and conditions, access to health care, and use of preventive health services related to the leading causes of death and disability. BRFSS data were analyzed for 398,208 adults aged ≥18 years to estimate the prevalence of five self-reported health-related behaviors (sufficient sleep, current nonsmoking, nondrinking or moderate drinking, maintaining normal body weight, and meeting aerobic leisure time physical activity recommendations) by urban-rural status. For this report, rural is defined as the noncore counties described in the 2013 National Center for Health Statistics Urban-Rural Classification Scheme for Counties. RESULTS: Approximately one third of U.S. adults practice at least four of these five behaviors. Compared with adults living in the four types of metropolitan counties (large central metropolitan, large fringe metropolitan, medium metropolitan, and small metropolitan), adults living in the two types of nonmetropolitan counties (micropolitan and noncore) did not differ in the prevalence of sufficient sleep; had higher prevalence of nondrinking or moderate drinking; and had lower prevalence of current nonsmoking, maintaining normal body weight, and meeting aerobic leisure time physical activity recommendations. The overall age-adjusted prevalence of reporting at least four of the five health-related behaviors was 30.4%. The prevalence among the estimated 13.3 million adults living in noncore counties was lower (27.0%) than among those in micropolitan counties (28.8%), small metropolitan counties (29.5%), medium metropolitan counties (30.5%), large fringe metropolitan counties (30.2%), and large metropolitan centers (31.7%). INTERPRETATION: This is the first report of the prevalence of these five health-related behaviors for the six urban-rural categories. Nonmetropolitan counties have lower prevalence of three and clustering of at least four health-related behaviors that are associated with the leading chronic disease causes of death. Prevalence of sufficient sleep was consistently low and did not differ by urban-rural status. PUBLIC HEALTH ACTION: Chronic disease prevention efforts focus on improving the communities, schools, worksites, and health systems in which persons live, learn, work, and play. Evidence-based strategies to improve health-related behaviors in the population of the United States can be used to reach the Healthy People 2020 objectives for these five self-reported health-related behaviors (sufficient sleep, current nonsmoking, nondrinking or moderate drinking, maintaining normal body weight, and meeting aerobic leisure time physical activity recommendations). These findings suggest an ongoing need to increase public awareness and public education, particularly in rural counties where prevalence of these health-related behaviors is lowest. |
Disparities in adult cigarette smoking - United States, 2002-2005 and 2010-2013
Martell BN , Garrett BE , Caraballo RS . MMWR Morb Mortal Wkly Rep 2016 65 (30) 753-8 Although cigarette smoking has substantially declined since the release of the 1964 Surgeon General's report on smoking and health,* disparities in tobacco use exist among racial/ethnic populations (1). Moreover, because estimates of U.S. adult cigarette smoking and tobacco use are usually limited to aggregate racial or ethnic population categories (i.e., non-Hispanic whites [whites]; non-Hispanic blacks or African Americans [blacks]; American Indians and Alaska Natives [American Indians/Alaska Natives]; Asians; Native Hawaiians or Pacific Islanders [Native Hawaiians/Pacific Islanders]; and Hispanics/Latinos [Hispanics]), these estimates can mask differences in cigarette smoking prevalence among subgroups of these populations. To assess the prevalence of and changes in cigarette smoking among persons aged ≥18 years in six racial/ethnic populations and 10 select subgroups in the United States,(dagger) CDC analyzed self-reported data collected during 2002-2005 and 2010-2013 from the National Survey on Drug Use and Health (NSDUH) (2) and compared differences between the two periods. During 2010-2013, the overall prevalence of cigarette smoking among the racial/ethnic populations and subgroups ranged from 38.9% for American Indians/Alaska Natives to 7.6% for both Chinese and Asian Indians. During 2010-2013, although cigarette smoking prevalence was relatively low among Asians overall (10.9%) compared with whites (24.9%), wide within-group differences in smoking prevalence existed among Asian subgroups, from 7.6% among both Chinese and Asian Indians to 20.0% among Koreans. Similarly, among Hispanics, the overall prevalence of current cigarette smoking was 19.9%; however, within Hispanic subgroups, prevalences ranged from 15.6% among Central/South Americans to 28.5% among Puerto Ricans. The overall prevalence of cigarette smoking was higher among men than among women during both 2002-2005 (30.0% men versus 23.9% women) and 2010-2013 (26.4% versus 21.1%) (p<0.05). These findings highlight the importance of disaggregating tobacco use estimates within broad racial/ethnic population categories to better understand and address disparities in tobacco use among U.S. adults. |
Does a race-gender-age crossover effect exist in current cigarette smoking between non-Hispanic blacks and non-Hispanic whites? United States, 2001-2013
Caraballo RS , Sharapova SR , Asman KJ . Nicotine Tob Res 2016 18 Suppl 1 S41-8 INTRODUCTION: For years, national US surveys have found a lower prevalence of cigarette smoking among non-Hispanic (NH) black adolescents and young adults than their NH white counterparts while finding either similar or higher prevalence in NH blacks among older adults. We present results from four US surveys, including one supplemented by cotinine data, to determine if a race-gender-age crossover effect exists between NH black and NH white current cigarette smokers. METHODS: We present NH black and NH white current cigarette smoking estimates in the National Youth Tobacco Survey (2004-2013), National Survey on Drug Use and Health (2002-2013), National Health Interview Survey (2001-2013), and National Health and Nutrition Examination Survey (2001-2012). RESULTS: All surveys consistently found that NH black females aged 12-25 years had a lower smoking prevalence than NH white females of the same age while NH black males aged 26 years or older had a higher smoking prevalence than NH white males of the same age. Results were inconsistent between surveys for current smoking estimates for males 12-25 years and females aged 26 years or older. CONCLUSION: Our results are inconclusive in consistently detecting the existence of a race-gender-age crossover effect for current cigarette smoking between NH blacks and NH whites. National birth cohort studies are better suited to detect a race-gender-age crossover effect in smoking prevalence between these two racial groups. |
Not just cigarettes: A more comprehensive look at marijuana and tobacco use among African American and white youth and young adults
Kennedy SM , Caraballo RS , Rolle IV , Rock VJ . Nicotine Tob Res 2016 18 Suppl 1 S65-72 INTRODUCTION: Cigarettes, cigars, and marijuana have generally been studied in isolation yet their use does not occur in isolation. Focus on cigarette smoking may overstate the observation that African American youth and young adults are less likely to smoke any combustible product compared with their white counterparts. Assessing cigarette, cigar, and marijuana use trends may help identify the extent of this difference. METHODS: Data from the 2002-2012 National Survey on Drug Use and Health (N = 25 541 to N = 28 232) were used to investigate past 30-day cigarette, cigar, and marijuana use trends among African American and white youth (12-17) and young adults (18-25). Logistic regressions assessed trends in combustible tobacco (cigarettes and cigars) and marijuana use, alone and in combination. RESULTS: From 2002-2012, the absolute difference in cigarette smoking prevalence between African American and white youth (9.6%-4.2%) and young adults (19.0%-10.5%) narrowed. Any combustible tobacco/marijuana use was significantly lower among African Americans than whites but, relative to cigarettes, the absolute difference was much smaller among youth (7.2%-2.2%) and young adults (15.8%-5.6%). Among any combustible tobacco/marijuana users, using two or more substances ranged from 31.4% to 40.3% among youth and 29.1% to 39.8% among young adults. CONCLUSION: Any combustible tobacco/marijuana use trends suggest the smoking prevalence difference between African American and white youth and young adults is real, but less pronounced than when assessing cigarette smoking alone. Policies and programs addressing smoking behaviors may benefit from broadening focus to monitor and address cigar and marijuana use as well. IMPLICATIONS: Trends in any use of cigarettes, cigars, and/or marijuana suggest the difference in smoking prevalence between African American and white youth and young adults is real, but less pronounced than when cigarette smoking is assessed alone. In 2012, more than 10% of African American and white youth, more than a third of African American young adults, and nearly half of white young adults reported past 30-day use of cigarette, cigars, and/or marijuana. Public health programs aimed at reducing these behaviors among youth and young adults could be informed by considering detailed, race-specific information regarding tobacco and marijuana use patterns. |
Electronic nicotine delivery system use among U.S. adults, 2014
Caraballo RS , Jamal A , Nguyen KH , Kuiper NM , Arrazola RA . Am J Prev Med 2015 50 (2) 226-9 INTRODUCTION: Electronic nicotine delivery system (ENDS) use has increased rapidly in the U.S. in recent years. The availability and use of ENDS raise new issues for public health practice and tobacco regulation, as it is unknown whether patterns of ENDS use enhance, deter, or have no impact on combustible tobacco product use. This study assessed past-month, lifetime, and frequency of ENDS use among current, former, and never adult cigarette smokers. METHODS: Data were analyzed from the 2014 Styles, a national consumer-based probability-based web panel survey of U.S. adults aged ≥18 years (n=4,269) conducted during June and July. Lifetime ENDS users were defined as those who reported having used ENDS ≥1 day in their lifetime. Past-month ENDS users were defined as those who reported using ENDS in the past 30 days. RESULTS: In 2014, overall lifetime and past-month ENDS use was 14.1% and 4.8%, respectively. By smoking status, 49.5% of current, 14.7% of former, and 4.1% of never cigarette smokers had used ENDS in their lifetime, whereas 20.6% of current, 4.0% of former, and 0.8% of never smokers used ENDS in the past month. Among current and former cigarette smokers who ever used ENDS, 44.1% and 44.7% reported using ENDS >10 days in their lifetime, respectively. CONCLUSIONS: Because the effect ENDS use has on combustible tobacco products use is unknown, and lifetime and past-month ENDS use is more common among current than former or never smokers, continued surveillance of ENDS use among adults is critical to programs and policies. |
Is every smoker interested in price promotions? An evaluation of price-related discounts by cigarette brands
Xu X , Wang X , Caraballo RS . J Public Health Manag Pract 2016 22 (1) 20-8 CONTEXT: Raising unit price is one of the most effective ways of reducing cigarette consumption. A large proportion of US adult smokers use generic brands or price discounts in response to higher prices, which may mitigate the public health impacts of raising unit price. OBJECTIVE: The main purpose of this study was to evaluate the retail price impact and the determinants of price-related discount use among US adult smokers by their most commonly used cigarette brand types. METHODS: Data from the 2009-2010 National Adult Tobacco Survey, a telephone survey of US adults 18 years or older, was used to assess price-related discount use by cigarette brands. Price-related discounts included coupons, rebates, buy 1 get 1 free, 2 for 1, or any other special promotions. Multivariate logistic regression was used to assess sociodemographic and tobacco use determinants of discount use by cigarette brands. RESULTS: Discount use was most common among premium brand users (22.1%), followed by generic (13.3%) and other brand (10.8%) users. Among premium brand users, those who smoked 10 to 20 cigarettes per day were more likely to use discounts, whereas elderly smokers, non-Hispanic blacks, those with greater annual household income, dual users of cigarettes and other combustible tobacco products, and those who had no quit intentions were less likely to do so. Among generic brand users, those who had no quit intentions and those who smoked first cigarette within 60 minutes after waking were more likely to use discounts. CONCLUSIONS: Frequent use of discounts varies between smokers of premium and generic cigarette brands. Setting a high minimum price, together with limiting the use of coupons and promotions, may uphold the effect of cigarette excise taxes to reduce smoking prevalence. |
Current cigarette smoking among adults - United States, 2005-2014
Jamal A , Homa DM , O'Connor E , Babb SD , Caraballo RS , Singh T , Hu SS , King BA . MMWR Morb Mortal Wkly Rep 2015 64 (44) 1233-1240 Tobacco smoking is the leading cause of preventable disease and death in the United States, resulting in approximately 480,000 premature deaths and more than $300 billion in direct health care expenditures and productivity losses each year (1). To assess progress toward achieving the Healthy People 2020 objective of reducing the percentage of U.S. adults who smoke cigarettes to </=12.0%,* CDC assessed the most recent national estimates of smoking prevalence among adults aged >/=18 years using data from the 2014 National Health Interview Survey (NHIS). The percentage of U.S. adults who smoke cigarettes declined from 20.9% in 2005 to 16.8% in 2014. Among daily cigarette smokers, declines were observed in the percentage who smoked 20-29 cigarettes per day (from 34.9% to 27.4%) or >/=30 cigarettes per day (from 12.7% to 6.9%). In 2014, prevalence of cigarette smoking was higher among males, adults aged 25-44 years, multiracial persons and American Indian/Alaska Natives, persons who have a General Education Development certificate, live below the federal poverty level, live in the Midwest, are insured through Medicaid or are uninsured, have a disability or limitation, or are lesbian, gay, or bisexual. Proven population-based interventions, including tobacco price increases, comprehensive smoke-free laws, high impact mass media campaigns, and barrier-free access to quitting assistance, are critical to reduce cigarette smoking and smoking-related disease and death among U.S. adults. |
Frequency of tobacco use among middle and high school students - United States, 2014
Neff LJ , Arrazola RA , Caraballo RS , Corey CG , Cox S , King BA , Choiniere CJ , Husten CG . MMWR Morb Mortal Wkly Rep 2015 64 (38) 1061-5 The use of tobacco products during adolescence increases the risk for adverse health effects and lifelong nicotine addiction. In 2014, an estimated 4.6 million middle and high school students were current users of any tobacco product, of whom an estimated 2.2 million were current users of two or more types of tobacco products. Symptoms of nicotine dependence are increased for multiple tobacco product users compared with single-product users. CDC and the Food and Drug Administration (FDA) analyzed data from the 2014 National Youth Tobacco Survey (NYTS) to determine how frequently (the number of days in the preceding 30 days) U.S. middle school (grades 6-8) and high school (grades 9-12) students used cigarettes, e-cigarettes, cigars, and smokeless tobacco products. Among current users (>/=1 day during the preceding 30 days) in high school, frequent use (>/=20 days during the preceding 30 days) was most prevalent among smokeless tobacco users (42.0%), followed by cigarette smokers (31.6%), e-cigarette users (15.5%), and cigar smokers (13.1%); a similar pattern was observed for those who used during all 30 days. Among current users in middle school, frequent use was greatest among smokeless tobacco users (29.2%), followed by cigarette smokers (20.0%), cigar smokers (13.2%) and e-cigarette users (11.8%). Current use of two or more types of tobacco products was common, even among students who used tobacco products 1-5 days during the preceding 30 days: 77.3% for cigar smokers, 76.9% for cigarette smokers, 63.4% for smokeless tobacco users, and 54.8% for e-cigarettes users. Preventing youths from initiating the use of any tobacco product is important to tobacco use prevention and control strategies in the United States. Monitoring the frequency and patterns of tobacco use among youths, including the use of two or more tobacco products, is important to inform evidence-based interventions to prevent and reduce all forms of tobacco use among youths. |
Combustible and smokeless tobacco use among high school athletes - United States, 2001-2013
Agaku IT , Singh T , Jones SE , King BA , Jamal A , Neff L , Caraballo RS . MMWR Morb Mortal Wkly Rep 2015 64 (34) 935-9 Athletes are not a typical at-risk group for smoking combustible tobacco products, because they are generally health conscious and desire to remain fit and optimize athletic performance (1). In contrast, smokeless tobacco use historically has been associated with certain sports, such as baseball (2). Athletes might be more likely to use certain tobacco products, such as smokeless tobacco, if they perceive them to be harmless (3); however, smokeless tobacco use is not safe and is associated with increased risk for pancreatic, esophageal, and oral cancers (4). Tobacco use among youth athletes is of particular concern, because most adult tobacco users first try tobacco before age 18 years (5). To examine prevalence and trends in current (>/=1 day during the past 30 days) use of combustible tobacco (cigarettes, cigars) and smokeless tobacco (chewing tobacco, snuff, or dip [moist snuff]) products among athlete and nonathlete high school students, CDC analyzed data from the 2001-2013 National Youth Risk Behavior Surveys. Current use of any tobacco (combustible or smokeless tobacco) significantly declined from 33.9% in 2001 to 22.4% in 2013; however, current smokeless tobacco use significantly increased from 10.0% to 11.1% among athletes, and did not change (5.9%) among nonathletes. Furthermore, in 2013, compared with nonathletes, athletes had significantly higher odds of being current smokeless tobacco users (adjusted odds ratio [AOR] = 1.77, p<0.05), but significantly lower odds of being current combustible tobacco users (AOR = 0.80, p<0.05). These findings suggest that opportunities exist for development of stronger tobacco control and prevention measures targeting youth athletes regarding the health risks associated with all forms of tobacco use. |
Tobacco use among middle and high school students - United States, 2011-2014
Arrazola RA , Singh T , Corey CG , Husten CG , Neff LJ , Apelberg BJ , Bunnell RE , Choiniere CJ , King BA , Cox S , McAfee T , Caraballo RS . MMWR Morb Mortal Wkly Rep 2015 64 (14) 381-385 Tobacco use and addiction most often begin during youth and young adulthood. Youth use of tobacco in any form is unsafe. To determine the prevalence and trends of current (past 30-day) use of nine tobacco products (cigarettes, cigars, smokeless tobacco, e-cigarettes, hookahs, tobacco pipes, snus, dissolvable tobacco, and bidis) among U.S. middle (grades 6-8) and high school (grades 9-12) students, CDC and the Food and Drug Administration (FDA) analyzed data from the 2011-2014 National Youth Tobacco Surveys (NYTS). In 2014, e-cigarettes were the most commonly used tobacco product among middle (3.9%) and high (13.4%) school students. Between 2011 and 2014, statistically significant increases were observed among these students for current use of both e-cigarettes and hookahs (p<0.05), while decreases were observed for current use of more traditional products, such as cigarettes and cigars, resulting in no change in overall tobacco use. Consequently, 4.6 million middle and high school students continue to be exposed to harmful tobacco product constituents, including nicotine. Nicotine exposure during adolescence, a critical window for brain development, might have lasting adverse consequences for brain development, causes addiction, and might lead to sustained tobacco use. For this reason, comprehensive and sustained strategies are needed to prevent and reduce the use of all tobacco products among youths in the United States. |
The relation between tobacco taxes and youth and young adult smoking: what happened following the 2009 U.S. federal tax increase on cigarettes?
van Hasselt M , Kruger J , Han B , Caraballo RS , Penne MA , Loomis B , Gfroerer JC . Addict Behav 2015 45c 104-109 BACKGROUND: On April 1, 2009, the federal government raised cigarette taxes from $0.39 to $1.01 per pack. This study examines the impact of this increase on a range of smoking behaviors among youth aged 12 to 17 and young adults aged 18 to 25. METHODS: Data from the 2002-2011 National Survey on Drug Use and Health (NSDUH) were used to estimate the impact of the tax increase on five smoking outcomes: (1) past year smoking initiation, (2) past-month smoking, (3) past year smoking cessation, (4) number of days cigarettes were smoked during the past month, and (5) average number of cigarettes smoked per day. Each model included individual and state-level covariates and other tobacco control policies that coincided with the tax increase. We examined the impact overall and by race and gender. RESULTS: The odds of smoking initiation decreased for youth after the tax increase (odds ratio (OR)=0.83, p<0.0001). The odds of past-month smoking also decreased (youth: OR=0.83, p<0.0001; young adults: OR=0.92, p<0.0001), but the odds of smoking cessation remained unchanged. Current smokers smoked on fewer days (youth: coefficient=-0.97, p=0.0001; young adults: coefficient=-0.84, p<0.0001) and smoked fewer cigarettes per day after the tax increase (youth: coefficient=-1.02, p=0.0011; young adults: coefficient=-0.92, p<0.0001). CONCLUSIONS: The 2009 federal cigarette tax increase was associated with a substantial reduction in smoking among youths and young adults. The impact of the tax increase varied across male, female, white and black subpopulations. |
Vital Signs: disparities in nonsmokers' exposure to secondhand smoke - United States, 1999-2012
Homa DM , Neff LJ , King BA , Caraballo RS , Bunnell RE , Babb SD , Garrett BE , Sosnoff CS , Wang L . MMWR Morb Mortal Wkly Rep 2015 64 (4) 103-108 BACKGROUND: Exposure to secondhand smoke (SHS) from burning tobacco causes disease and death in nonsmoking children and adults. No risk-free level of SHS exposure exists. METHODS: National Health and Nutrition Examination Survey (NHANES) data from 1999-2012 were used to examine SHS exposure among the nonsmoking population aged ≥3 years. SHS exposure among nonsmokers was defined as a serum cotinine level (a metabolite of nicotine) of 0.05-10 ng/mL. SHS exposure was assessed overall and by age, sex, race/ethnicity, poverty level, education, and whether the respondent owned or rented their housing. RESULTS: Prevalence of SHS exposure in nonsmokers declined from 52.5% during 1999-2000 to 25.3% during 2011-2012. During this period, declines were observed for all population subgroups, but disparities exist. During 2011-2012, SHS was highest among: children aged 3-11 years (40.6%), non-Hispanic blacks (46.8%), persons living below the poverty level (43.2%), and persons living in rental housing (36.8%). Among children aged 3-11 years, 67.9% of non-Hispanic blacks were exposed to SHS compared with 37.2% of non-Hispanic whites and 29.9% of Mexican Americans. CONCLUSION: Overall, SHS exposure in the United States has been reduced by half since 1999-2000. However, 58 million persons were still exposed to SHS during 2011-2012, and exposure remains higher among children, non-Hispanic blacks, those living in poverty, and those who rent their housing. IMPLICATIONS FOR PUBLIC HEALTH PRACTICE: Eliminating smoking in indoor spaces fully protects nonsmokers from SHS exposure; separating smokers from nonsmokers, cleaning the air and ventilating buildings cannot completely eliminate exposure. Continued efforts to promote implementation of comprehensive statewide laws prohibiting smoking in workplaces and public places, smoke-free policies in multiunit housing, and voluntary smoke-free home and vehicle rules are critical to protect nonsmokers from this preventable health hazard in the places they live, work, and gather. |
Intentions to smoke cigarettes among never-smoking U.S. middle and high school electronic cigarette users, National Youth Tobacco Survey, 2011-2013
Bunnell RE , Agaku IT , Arrazola R , Apelberg BJ , Caraballo RS , Corey CG , Coleman B , Dube SR , King BA . Nicotine Tob Res 2014 17 (2) 228-35 INTRODUCTION: Electronic cigarette (e-cigarette) use is increasing rapidly and their impact on youth is unknown. We assessed associations between e-cigarette use and smoking intentions among U.S. youth who had never smoked conventional cigarettes. METHODS: We analyzed data from the nationally representative 2011, 2012, and 2013 National Youth Tobacco Surveys of students in grades 6-12. Youth reporting they would definitely not smoke in the next year or if offered a cigarette by a friend were defined as not having an intention to smoke, while all others were classified as having positive intention to smoke conventional cigarettes. Demographics, pro-tobacco advertisement exposure, ever use of e-cigarettes, and ever use of other combustibles (cigars, hookah, bidis, kreteks, and pipes) and non-combustibles (chewing tobacco, snuff, dip, snus, and dissolvables) were included in multivariate analyses assessing associations with smoking intentions among never-cigarette-smoking youth. RESULTS: Between 2011-2013, the number of never-smoking youth who used e-cigarettes increased three-fold, from 79,000 to over 263,000. Intention to smoke conventional cigarettes was 43.9% among ever e-cigarette users and 21.5% among never users. Ever e-cigarette users had higher adjusted odds of having smoking intentions than never users (Adjusted Odds Ratio: 1.70, 95% Confidence Interval: 1.24-2.32). Those who ever used other combustibles, ever used non-combustibles, or reported pro-tobacco advertisement exposure also had increased odds of smoking intentions. CONCLUSION: In 2013, over a quarter million never-smoking youth had used e-cigarettes. E-cigarette use was associated with increased intentions to smoke cigarettes. Enhanced prevention efforts for youth are important for all forms of tobacco, including e-cigarettes. |
Exposure to tobacco coupons among U.S. middle and high school students
Tessman GK , Caraballo RS , Corey CG , Xu X , Chang CM . Am J Prev Med 2014 47 S61-8 BACKGROUND: Tobacco marketing contributes to increased tobacco use susceptibility and sustained use. There are limited data on youth exposure to tobacco coupons, a type of pro-tobacco promotion. PURPOSE: To explore channels through which youth report exposure to coupons and characteristics associated with this exposure. This may help inform efforts aimed at decreasing youth exposure to advertising and promotion. METHODS: Data from the 2012 National Youth Tobacco Survey were analyzed in 2013 to estimate the self-reported prevalence of U.S. middle and high school student exposure to coupons through various channels. Associations among exposure to coupons and demographics, tobacco use, living with a tobacco user, and receptivity to tobacco marketing were examined using multivariate logistic regression models. RESULTS: Approximately 13% of students reported exposure to tobacco coupons in the past 30 days through mail, digital communications, or tobacco packages. Prevalence was greatest among current tobacco users (34.0%) and those receptive to tobacco marketing (23.4%) compared to non-tobacco users (9.3%) and those not receptive to tobacco marketing (8.2%), respectively. Coupon exposure varied by sex, grade, and race/ethnicity. In adjusted models, current tobacco use (AOR=3.4, 95% CI=3.0, 3.9); living with a tobacco user (AOR=2.1, 95% CI=1.9, 2.4); and receptivity to tobacco marketing (AOR=2.3, 95% CI=2.0, 2.7) were independently associated with coupon exposure. CONCLUSIONS: Findings from this study indicate that despite restrictions on marketing to youth, youth are still being exposed to tobacco promotions such as coupons. Efforts to limit youth exposure may be valuable in reducing curiosity, susceptibility, and initiation. |
Symptoms of tobacco dependence among middle and high school tobacco users: results from the 2012 national youth tobacco survey
Apelberg BJ , Corey CG , Hoffman AC , Schroeder MJ , Husten CG , Caraballo RS , Backinger CL . Am J Prev Med 2014 47 S4-s14 BACKGROUND: A growing body of evidence suggests that tobacco dependence symptoms can occur soon after smoking onset and with low levels of use. However, limited data are available nationally and among non-cigarette tobacco users. PURPOSE: To examine the prevalence and determinants of tobacco dependence symptoms among adolescent tobacco users in the 2012 National Youth Tobacco Survey, a nationally representative, school-based survey of U.S. middle and high school students. METHODS: Multivariate logistic regression was used to identify independent predictors of dependence symptoms among current users (i.e., past 30-day use) of cigarettes, cigars, or smokeless tobacco. Analyses were conducted in 2013 using SAS-callable SUDAAN, version 11 to account for the complex survey design. RESULTS: Prevalence of tobacco dependence symptoms ranged from 20.8% (95% CI=18.6, 23.1) of current tobacco users reporting wanting to use tobacco within 30 minutes of waking to 41.9% (95% CI=39.3, 44.5) reporting recent strong cravings. Reporting of dependence symptoms was most consistently associated with polytobacco use, higher frequency of use, earlier initiation age, and female gender. A 2-4-fold increase in the odds of symptom reporting was found in adolescents using tobacco products on as few as 3-5 days compared to those who only used it for 1-2 of the past 30 days. CONCLUSIONS: A substantial proportion of U.S. adolescent tobacco users, including those with low levels of use, report symptoms of tobacco dependence. These findings demonstrate the need for full implementation of evidence-based strategies to prevent both experimentation and progression to regular tobacco use among youth. |
Usual source of cigarettes and alcohol among US high school students
Everett Jones S , Caraballo RS . J Sch Health 2014 84 (8) 493-501 BACKGROUND: Cigarette and alcohol use are common among youth. We examined sources of cigarettes and alcohol among youth who were current cigarette and alcohol users. METHODS: We analyzed nationally representative data from the 2009 and 2011 national Youth Risk Behavior Surveys-biennial, school-based surveys of high school students in the United States. Students completed anonymous, self-administered questionnaires. Overall response rates were 71% for both years. RESULTS: Among the 17.3% of current cigarette users <18 years, 27.3% usually gave someone else money to buy their cigarettes and 27.7% usually borrowed (bummed) them. Fewer (14.1%) usually bought their own cigarettes in a store. Among the 40.3% of current alcohol users, 24.3% usually gave someone else money to buy it and 41.2% usually had someone give it to them. A few (4.5%) usually bought their own alcohol in a store. Age and intensity of use were positively associated with students buying their own cigarettes or alcohol, but negatively associated with students borrowing or having someone else give it to them. CONCLUSIONS: Because social and commercial sources of cigarettes and alcohol are common, multiple strategies are needed to reduce the ability for youth to obtain them and reduce their desire for them. |
Can you refuse these discounts? An evaluation of the use and price discount impact of price-related promotions among US adult smokers by cigarette manufacturers
Caraballo RS , Wang X , Xu X . BMJ Open 2014 4 (6) e004685 OBJECTIVES: The raising unit price of cigarette has been shown to be one of the most effective ways of reducing cigarette consumption and increasing rates of successful quitting. However, researchers have shown that price-sensitive smokers have used a variety of strategies to mitigate the effect of the rising price of cigarettes on their smoking habits. In particular, 23-34% of adult smokers in the US use cheaper brands, and 18-55% use coupons or promotions. Little is known about the discount use by type of brands. As such, the main purpose of this analysis is to evaluate the uses and price discount effects of these price-related discounts by manufacturers and major brands. SETTING: An analysis based on the cross-sectional 2009-2010 National Adult Tobacco Survey (NATS). PARTICIPANTS: 11 766 current smokers aged 18 or above in the USA. PRIMARY OUTCOME MEASURES: Price-related discount was defined as smokers who used coupons, rebates, buy-one-get-one-free, two-for-one or any other special promotions for their last cigarettes purchase. RESULTS: The use of price-related discounts and associated price impact vary widely by cigarette manufacturer and brand. Approximately one of three Camel, one of four Marlboro and one of eight Newport smokers used price-related discounts on their latest cigarette purchases. The average price reductions of discounts offered by Philip Morris (PM) or R.J. Reynolds (RJR) were around 29 cents per pack while that of Lorillard (Newport only) was 24 cents per pack. Cigarette brands that provided significant per pack price reductions include: PM Marlboro (28 cents), RJR brand Camel (41 cents), Doral (50 cents), Kool (73 cents) and Salem (80 cents), and Lorillard Newport (24 cents). CONCLUSIONS: Policies that decrease price-minimisation strategies will benefit public health. |
Lung cancer screening with low-dose computed tomography for primary care providers
Richards TB , White MC , Caraballo RS . Prim Care 2014 41 (2) 307-330 This review provides an update on lung cancer screening with low-dose computed tomography (LDCT) and its implications for primary care providers. One of the unique features of lung cancer screening is the potential complexity in patient management if an LDCT scan reveals a small pulmonary nodule. Additional tests, consultation with multiple specialists, and follow-up evaluations may be needed to evaluate whether lung cancer is present. Primary care providers should know the resources available in their communities for lung cancer screening with LDCT and smoking cessation, and the key points to be addressed in informed and shared decision-making discussions with patients. |
Are tobacco control policies effective in reducing young adult smoking?
Farrelly MC , Loomis BR , Kuiper N , Han B , Gfroerer J , Caraballo RS , Pechacek TF , Couzens GL . J Adolesc Health 2014 54 (4) 481-6 PURPOSE: We examined the influence of tobacco control program funding, smoke-free air laws, and cigarette prices on young adult smoking outcomes. METHODS: We use a natural experimental design approach that uses the variation in tobacco control policies across states and over time to understand their influence on tobacco outcomes. We combine individual outcome data with annual state-level policy data to conduct multivariable logistic regression models, controlling for an extensive set of sociodemographic factors. The participants are 18- to 25-year-olds from the 2002-2009 National Surveys on Drug Use and Health. The three main outcomes are past-year smoking initiation, and current and established smoking. A current smoker was one who had smoked on at least 1 day in the past 30 days. An established smoker was one who had smoked 1 or more cigarettes in the past 30 days and smoked at least 100 cigarettes in his or her lifetime. RESULTS: Higher levels of tobacco control program funding and greater smoke-free-air law coverage were both associated with declines in current and established smoking (p < .01). Greater coverage of smoke-free air laws was associated with lower past year initiation with marginal significance (p = .058). Higher cigarette prices were not associated with smoking outcomes. Had smoke-free-air law coverage and cumulative tobacco control funding remained at 2002 levels, current and established smoking would have been 5%-7% higher in 2009. CONCLUSIONS: Smoke-free air laws and state tobacco control programs are effective strategies for curbing young adult smoking. |
Cigarette smoking - United States, 2006-2008 and 2009-2010
Garrett BE , Dube SR , Winder C , Caraballo RS . MMWR Suppl 2013 62 (3) 81-4 Cigarette smoking is the leading cause of preventable disease and death in the United States, resulting in approximately 443,000 deaths and $193 billion in direct health-care expenditures and productivity losses each year. Declines in smoking prevalence would significantly impact the health-care and economic costs of smoking. Efforts to accelerate the decline in cigarette smoking include reducing cigarette smoking disparities among specific population groups. Findings from the previous report on cigarette use in the first CDC Health Disparities and Inequalities Report (CHDIR) indicated that progress has been achieved in reducing disparities in cigarette smoking among certain racial/ethnic groups. However, little progress has been made in reducing disparities in cigarette smoking among persons of low socioeconomic status (SES) and low educational attainment. |
Relapse among cigarette smokers: the CARDIA longitudinal study - 1985-2011
Caraballo RS , Kruger J , Asman K , Pederson L , Widome R , Kiefe CI , Hitsman B , Jacobs DR Jr . Addict Behav 2013 39 (1) 101-6 RATIONALE: There is little information about long-term relapse patterns for cigarette smokers. OBJECTIVE: To describe long-term prevalence of relapse and related smoking patterns by sex, race, age, and education level among a community-based cohort of young adults followed for 25years. METHODS: We examined 25years of data from Coronary Artery Risk Development in Young Adults (CARDIA), an ongoing study of a community-based cohort of 5115 men and women aged 18 to 30years at baseline with periodic re-examinations. At each examination smoking, quitting, and relapse were queried. We examined prevalence of smoking relapse among 3603 participants who attended at least 6 of the 8 examinations. RESULTS: About 53% of 3603 participants never reported smoking on a regular basis. Among the remaining 1682 ever smokers, 52.8% of those who reported current smoking at baseline were still smoking by the end of the study, compared to 10.7% of those who initiated smoking by year 5. Among those classified as former smokers at baseline, 39% relapsed at least once; of these, 69.5% had quit again by the end of the study. Maximum education level attained, age at study baseline, and race were associated with failure to quit smoking by the end of the study and relapse among those who did quit. Maximum education level attained and age at study baseline were also associated with ability to successfully quit after a relapse. CONCLUSIONS: Smoking relapse after quitting is common, especially in those with lower education level. Education was the strongest predictor of all three outcomes. Improvements in access to treatment and treatment options, especially for underserved populations, are needed to prevent relapse when smokers quit. |
A comprehensive examination of the influence of state tobacco control programs and policies on youth smoking
Farrelly MC , Loomis BR , Han B , Gfroerer J , Kuiper N , Couzens GL , Dube S , Caraballo RS . Am J Public Health 2013 103 (3) 549-55 OBJECTIVES: We examined the influence of tobacco control policies (tobacco control program expenditures, smoke-free air laws, youth access law compliance, and cigarette prices) on youth smoking outcomes (smoking susceptibility, past-year initiation, current smoking, and established smoking). METHODS: We combined data from the 2002 to 2008 National Surveys on Drug Use and Health with state and municipality population data from the US Census Bureau to assess the associations between state tobacco control policy variables and youth smoking outcomes, focusing on youths aged 12 to 17 years. We also examined the influence of policy variables on youth access when these variables were held at 2002 levels. RESULTS: Per capita funding for state tobacco control programs was negatively associated with all 4 smoking outcomes. Smoke-free air laws were negatively associated with all outcomes except past-year initiation, and cigarette prices were associated only with current smoking. We found no association between these outcomes and retailer compliance with youth access laws. CONCLUSIONS: Smoke-free air laws and state tobacco control programs are effective strategies for curbing youth smoking. (Am J Public Health.
