Overview and methods for the Youth Risk Behavior Surveillance System - United States, 2023
Brener ND , Mpofu JJ , Krause KH , Everett Jones S , Thornton JE , Myles Z , Harris WA , Chyen D , Lim C , Arrey L , Mbaka CK , Trujillo L , Shanklin SL , Smith-Grant J , Whittle L , McKinnon II , Washington M , Queen BE , Roberts AM . MMWR Suppl 2024 73 (4) 1-12 The Youth Risk Behavior Surveillance System (YRBSS) is a set of surveys that tracks a broad range of behaviors, experiences, and conditions that can lead to poor health among high school students. The system includes a nationally representative Youth Risk Behavior Survey (YRBS) and separate school-based YRBSs conducted by states, tribes, territories, and local school districts. For the 2023 national YRBS, CDC made changes to the sampling method, survey administration mode, and questionnaire. Specifically, the sampling design added an American Indian or Alaska Native (AI/AN) supplemental sample so that separate, precise estimates could be made for AI/AN high school students, in addition to the usual sample designed to provide nationally representative data for the population of students in grades 9-12. To decrease the time needed to collect and process data, CDC changed the survey administration mode from paper-and-pencil scannable booklets to a tablet-based electronic survey. To provide national data on topics of emerging interest, CDC added new questions to the questionnaire. These new questions assessed social media use, experiences of racism at school, adverse childhood experiences, transgender identity, consent for sexual contact, and unfair discipline at school. Public health practitioners and researchers can use YRBSS data to examine the prevalence of youth health behaviors, experiences, and conditions; monitor trends; and guide interventions. This overview report describes 2023 YRBSS survey methodology, including sampling, data collection, data processing, weighting, and data analyses. The 2023 YRBS participation map, survey response rates, and a detailed examination of student demographic characteristics are included in this report. During 2023, in addition to the national YRBS, 68 site-level surveys were administered to high school students in 39 states, three tribal governments, five territories, and 21 local school districts. These site-level surveys use site-specific questionnaires that are similar to the national YRBS questionnaire but are modified to meet sites' needs. This overview and methods report is one of 11 featured in this MMWR supplement, which reports results from the 2023 national YRBS but does not include data from the 68 site-level surveys. Each report is based on data collected using methods presented in this overview report. A full description of YRBSS results and downloadable data are available (https://www.cdc.gov/yrbs/index.html). |
Adverse childhood experiences and health conditions and risk behaviors among high school students - Youth Risk Behavior Survey, United States, 2023
Swedo EA , Pampati S , Anderson KN , Thorne E , McKinnon II , Brener ND , Stinson J , Mpofu JJ , Niolon PH . MMWR Suppl 2024 73 (4) 39-50 Adverse childhood experiences (ACEs) are preventable, potentially traumatic events occurring before age 18 years. Data on ACEs among adolescents in the United States have primarily been collected through parent report and have not included important violence-related ACEs, including physical, sexual, and emotional abuse. This report presents the first national prevalence of self-reported ACEs among U.S. high school students aged <18 years, estimates associations between ACEs and 16 health conditions and risk behaviors, and calculates population-attributable fractions of ACEs with these conditions and behaviors using cross-sectional, nationally representative 2023 Youth Risk Behavior Survey data. Exposures were lifetime prevalence of individual (emotional, physical, and sexual abuse; physical neglect; witnessed intimate partner violence; household substance use; household poor mental health; and incarcerated or detained parent or guardian) ACEs and cumulative ACEs count (zero, one, two or three, or four or more). Health conditions and risk behaviors included violence risk factors, substance use, sexual behaviors, weight and weight perceptions, mental health, and suicidal thoughts and behaviors. Bivariate analyses assessed associations between individual and cumulative ACEs and demographics. Adjusted prevalence ratios assessed associations between cumulative ACEs and health conditions and risk behaviors, accounting for demographics. Population-attributable fractions were calculated to determine the potential reduction in health conditions and risk behaviors associated with preventing ACEs. ACEs were common, with approximately three in four students (76.1%) experiencing one or more ACEs and approximately one in five students (18.5%) experiencing four or more ACEs. The most common ACEs were emotional abuse (61.5%), physical abuse (31.8%), and household poor mental health (28.4%). Students who identified as female; American Indian or Alaska Native; multiracial; or gay or lesbian, bisexual, questioning, or who describe their sexual identity in some other way experienced the highest number of ACEs. Population-attributable fractions associated with experiencing ACEs were highest for suicide attempts (89.4%), seriously considering attempting suicide (85.4%), and prescription opioid misuse (84.3%). ACEs are prevalent among students and contribute substantially to numerous health conditions and risk behaviors in adolescence. Policymakers and public health professionals can use these findings to understand the potential public health impact of ACEs prevention to reduce adolescent suicidal behaviors, substance use, sexual risk behaviors, and other negative health conditions and risk behaviors and to understand current effects of ACEs among U.S. high school students. |
Mental health and suicide risk among high school students and protective factors - Youth Risk Behavior Survey, United States, 2023
Verlenden JV , Fodeman A , Wilkins N , Jones SE , Moore S , Cornett K , Sims V , Saelee R , Brener ND . MMWR Suppl 2024 73 (4) 79-86 Adolescent mental health and suicide risk remain substantial public health concerns. High pre-COVID rates of poor mental health and suicide-related behaviors have continued to rise, highlighting the need to identify factors that might foster positive mental health outcomes and reduce suicide-related behaviors at population levels. Using CDC's 2023 Youth Risk Behavior Survey, CDC analyzed the prevalence of mental health and suicide risk indicators and their associations with individual-, family-, and school- or community-level protective factors. Prevalence estimates were calculated for each of the mental health and suicide risk indicators by demographic characteristic. Prevalence ratios adjusted for sex, sexual identity, grade, and race and ethnicity were calculated to examine the association between protective factors and mental health and suicide risk indicators. Overall, 39.7% of students experienced persistent feelings of sadness and hopelessness, 28.5% experienced poor mental health, 20.4% seriously considered attempting suicide, and 9.5% had attempted suicide. Mental health and suicide risk indicators differed by sex, sexual identity, grade, and race and ethnicity. All protective factors were associated with lower prevalence of one or more risk indicators. Findings from this report can serve as a foundation for the advancement of research on protective factors and for the development and implementation of programs, practices, and policies that protect and promote mental health and emotional well-being among youth. |
Reliability of the 2021 National Youth Risk Behavior Survey Questionnaire
Jones SE , Brener ND , Queen B , Hershey-Arista M , Harris WA , Mpofu JJ , Underwood JM . Am J Health Promot 2024 8901171241239735 PURPOSE: The Youth Risk Behavior Survey (YRBS) monitors behaviors, experiences, and conditions affecting the health of high school students nationwide. This study examined the test-retest reliability of the 2021 national YRBS questionnaire. DESIGN: Respondents completed a Time 1 and Time 2 paper-and-pencil questionnaire approximately 2 weeks apart during February to May 2022. Data were linked in such a way as to preserve anonymity. SETTING: Convenience sample of high schools. SUBJECTS: High school students (N = 588). MEASURES: Health risk behaviors and experiences assessed on the 2021 national YRBS questionnaire. ANALYSIS: Time 1 and Time 2 responses were compared for each questionnaire item using the McNemar's test. Then, Cohen's kappa coefficients tested the agreement between Time 1 and Time 2 responses overall, and by sex, grade, and Black, White, and Hispanic race and ethnicity. RESULTS: Among the 74 items analyzed, 96% had at least moderate reliability, and 73% had substantial or almost perfect reliability. The mean Cohen's kappa was .68. McNemar's test findings showed Time 1 and Time 2 data significantly differed (P < .01) for 9 items (12%). CONCLUSION: Reliable health behavior measures are important in the development of youth-focused public health programs and policies. Findings suggest the national YRBS questionnaire is a reliable instrument. Such findings lend support to relying on adolescent self-reported data when monitoring health behaviors using the YRBS. |
Overview and methods for the youth risk behavior surveillance system - United States, 2021
Mpofu JJ , Underwood JM , Thornton JE , Brener ND , Rico A , Kilmer G , Harris WA , Leon-Nguyen M , Chyen D , Lim C , Mbaka CK , Smith-Grant J , Whittle L , Jones SE , Krause KH , Li J , Shanklin SL , McKinnon I , Arrey L , Queen BE , Roberts AM . MMWR Suppl 2023 72 (1) 1-12 The Youth Risk Behavior Surveillance System (YRBSS) is the largest public health surveillance system in the United States, monitoring a broad range of health-related behaviors among high school students. The system includes a nationally representative Youth Risk Behavior Survey (YRBS) and separate school-based YRBSs conducted by states, tribes, territories, and local school districts. In 2021, these surveys were conducted during the COVID-19 pandemic. The pandemic underscored the importance of data in understanding changes in youth risk behaviors and addressing the multifaceted public health needs of youths. This overview report describes 2021 YRBSS survey methodology, including sampling, data collection procedures, response rates, data processing, weighting, and analyses. The 2021 YRBS participation map, survey response rates, and a detailed examination of student demographic characteristics are included in this report. During 2021, in addition to the national YRBS, a total of 78 surveys were administered to high school students across the United States, representing the national population, 45 states, two tribal governments, three territories, and 28 local school districts. YRBSS data from 2021 provided the first opportunity since the onset of the COVID-19 pandemic to compare youth health behaviors using long-term public health surveillance. Approximately half of all student respondents represented racial and ethnic minority groups, and approximately one in four identified as lesbian, gay, bisexual, questioning, or other (a sexual identity other than heterosexual) (LGBQ+). These findings reflect shifts in youth demographics, with increased percentages of racial and ethnic minority and LGBQ+ youths compared with previous YRBSS cycles. Educators, parents, local decision makers, and other partners use YRBSS data to monitor health behavior trends, guide school health programs, and develop local and state policy. These and future data can be used in developing health equity strategies to address long-term disparities so that all youths can thrive in safe and supportive environments. This overview and methods report is one of 11 featured in this MMWR supplement. Each report is based on data collected using methods presented in this overview. A full description of YRBSS results and downloadable data are available (https://www.cdc.gov/healthyyouth/data/yrbs/index.htm). |
Overview and methodology of the Adolescent Behaviors and Experiences Survey - United States, January-June 2021
Rico A , Brener ND , Thornton J , Mpofu JJ , Harris WA , Roberts AM , Kilmer G , Chyen D , Whittle L , Leon-Nguyen M , Lim C , Saba A , Bryan LN , Smith-Grant J , Underwood JM . MMWR Suppl 2022 71 (3) 1-7 Many U.S. schools closed nationwide in March 2020 to prevent the spread of COVID-19. School closures and online-only instruction have negatively affected certain students, with studies showing adverse effects of the pandemic on mental health. However, little is known about other experiences such as economic and food insecurity and abuse by a parent, as well as risk behaviors such as alcohol and drug use among youths across the United States during the pandemic. To address this gap, CDC developed the one-time, online Adolescent Behaviors and Experiences Survey (ABES), which was conducted during January-June 2021 to assess student behaviors and experiences during the COVID-19 pandemic among high school students, including unintentional injury, violence, tobacco product use, sexual behaviors, and dietary behaviors. This overview report of the ABES MMWR Supplement describes the ABES methodology, including the student questionnaire and administration, sampling, data collection, weighting, and analysis. ABES used a stratified, three-stage cluster probability-based sampling approach to obtain a nationally representative sample of students in grades 9-12 attending public and private schools. Teachers of selected classes provided students with access to the anonymous online survey while following local consent procedures. Data were collected using a 110-item questionnaire during January-June 2021 in 128 schools. A total of 7,998 students submitted surveys, and 7,705 of these surveys had valid data (i.e., ≥20 questions answered). The school response rate was 38%, the student response rate was 48%, and the overall response rate was 18%. Information on mode of instruction and school-provided equipment was also collected from all sampled schools. This overview report provides student- and school-level characteristics obtained from descriptive analyses, and the other reports in the ABES MMWR Supplement include information on substance use, mental health and suicidality, perceived racism, and disruptions to student life among high school students. Findings from ABES during the COVID-19 pandemic can help guide parents, teachers, school administrators, community leaders, clinicians, and public health officials in decision-making for student support and school health programs. |
Dietary and physical activity behaviors among high school students - Youth Risk Behavior Survey, United States, 2019
Merlo CL , Jones SE , Michael SL , Chen TJ , Sliwa SA , Lee SH , Brener ND , Lee SM , Park S . MMWR Suppl 2020 69 (1) 64-76 Establishing healthy dietary and physical activity patterns among youths is an important public health strategy for improving health and preventing chronic diseases; however, few adolescents meet U.S. government recommendations for dietary or physical activity behaviors, and disparities by sex and race/ethnicity exist. CDC analyzed data from the 2019 Youth Risk Behavior Survey to update estimates of dietary and physical activity behaviors among U.S. high school students overall and by sex and race/ethnicity. In addition, 2-year comparisons (2017 and 2019) and trends in prevalence of these behaviors during 2009-2019 were examined. In 2019, overall, during the 7 days before the survey, 41.8% of students had eaten fruit or drunk 100% fruit juices <1 time/day; 40.7% had eaten vegetables <1 time/day; and 16.7% had not eaten breakfast on all 7 days. Moreover, although 57.4% of students had played on ≥1 sports team during the 12 months before the survey, less than half of students had been physically active for ≥60 minutes/day on all 7 days (23.2%), had exercised to strengthen or tone their muscles on ≥3 days/week (49.5%), had met both aerobic and muscle-strengthening physical activity guidelines (16.5%), or had attended physical education classes on all 5 days in an average school week (25.9%). Trend data indicate limited progress in shifting dietary and physical activity behaviors. That is, with the exception of decreases in the percentage of students who had consumed soda ≥1 time/day (2009: 29.2%; 2019: 15.1%), sports drinks ≥1 time/day (2015: 13.8%; 2019: 10.6%), and <3 glasses/day of plain water (2015: 50.5%; 2019: 44.6%), high school students' dietary and physical activity behaviors have not improved and, in certain cases, have worsened. These findings support the need for multicomponent approaches, including policy and environmental changes, and opportunities for adolescents to learn about and practice making healthy choices. |
Dietary and physical activity behaviors in 2021 and changes from 2019 to 2021 among high school students - Youth Risk Behavior Survey, United States, 2021
Michael SL , Jones SE , Merlo CL , Sliwa SA , Lee SM , Cornett K , Brener ND , Chen TJ , Ashley CL , Park S . MMWR Suppl 2023 72 (1) 75-83 The fall of 2021 was the first school semester to begin with widespread in-person learning since the COVID-19 pandemic began. Understanding dietary and physical activity behaviors of adolescents during this time can provide insight into potential health equity gaps and programmatic needs in schools and communities. This report uses data from the 2021 national Youth Risk Behavior Survey conducted among a nationally representative sample of U.S. public and private school students in grades 9-12 to update estimates of dietary and physical activity behaviors among U.S. high school students overall and by sex and race and ethnicity. In addition, 2-year comparisons (2019 versus 2021) of these behaviors were examined. In 2021, daily consumption of fruits, vegetables, and breakfast during the past 7 days remained low and decreased overall with specific disparities by sex and race and ethnicity from 2019 to 2021. The overall prevalence of students attending physical education classes daily, exercising to strengthen muscles on ≥3 days/week (i.e., met the guideline for muscle-strengthening activity), and playing on at least one sports team decreased from 2019 to 2021; whereas being physically active for ≥60 minutes/day on all 7 days (i.e., met the guideline for aerobic activity) and meeting both aerobic and muscle-strengthening guidelines remained low but did not change. These findings underscore the need for strategies to increase healthy dietary and physical activity behaviors both in the recovery phase of COVID-19 and longer term. |
Use of tobacco products, alcohol, and other substances among high school students during the COVID-19 pandemic - Adolescent Behaviors and Experiences Survey, United States, January-June 2021
Brener ND , Bohm MK , Jones CM , Puvanesarajah S , Robin L , Suarez N , Deng X , Harding RL , Moyse D . MMWR Suppl 2022 71 (3) 8-15 The COVID-19 pandemic has been associated with established risk factors for adolescent substance use, including social isolation, boredom, grief, trauma, and stress. However, little is known about adolescent substance use patterns during the pandemic. CDC analyzed data from the Adolescent Behaviors and Experiences Survey, an online survey of a probability-based, nationally representative sample of public- and private-school students in grades 9-12 (N = 7,705), to examine the prevalence of current use of tobacco products, alcohol, and other substances among U.S. high school students. Prevalence was examined by demographic characteristics and instructional models of the students' schools (in-person, virtual, or hybrid). During January-June 2021, 31.6% of high school students reported current use of any tobacco product, alcohol, or marijuana or current misuse of prescription opioids. Current alcohol use (19.5%), electronic vapor product (EVP) use (15.4%), and marijuana use (12.8%) were more prevalent than prescription opioid misuse (4.3%), current cigarette smoking (3.3%), cigar smoking (2.3%), and smokeless tobacco use (1.9%). Approximately one third of students who used EVPs did so daily, and 22.4% of students who drank alcohol did so ≥6 times per month. Approximately one in three students who ever used alcohol or other drugs reported using these substances more during the pandemic. The prevalence of substance use was typically higher among non-Hispanic American Indian or Alaska Native students, older students, and gay, lesbian, or bisexual students than among students of other racial or ethnic groups, younger students, and heterosexual students. The prevalence of alcohol use also was higher among non-Hispanic White students than those of other racial or ethnic groups. Students only attending school virtually had a lower prevalence of using most of the substances examined than did students attending schools with in-person or hybrid models. These findings characterizing youth substance use during the pandemic can help inform public health interventions and messaging to address these health risks during and after the COVID-19 pandemic. |
Reliability of the 2020 school health profiles principal and lead health education teacher questionnaires
Jones SE , Brener ND , Queen B , Hershey-Arista M , Harris W , Underwood JM . J Sch Health 2024 BACKGROUND: School Health Profiles assesses school health policies and practices among US secondary schools. METHODS: The 2020 School Health Profiles principal and teacher questionnaires were used for a test-retest reliability study. Cohen's kappa coefficients tested the agreement in dichotomous responses to each questionnaire variable at 2 time points. The aggregate prevalence estimates between time 1 and time 2 were compared for each questionnaire item via overlapping 95% confidence intervals. Chi-square tests examined whether the prevalence at time 2 differed between paper and web administration for both questionnaires. RESULTS: For the principal (N = 50) and teacher (N = 34) data, there were no significant differences in the prevalence of any items between time 1 and time 2. For the principal survey, the mean kappa for 191 variables was 0.49. For the teacher survey, the mean kappa for 260 variables was 0.65. Overall, 60.7% of principal and 91.1% of teacher questionnaire items had at least "moderate" reliability. CONCLUSIONS: School Health Profiles offers education and health agencies a reliable tool to monitor school policies and practices. |
Trends in diversity-related learning among secondary schools in 35 US states, 2014–2018
Young E , Demissie Z , Szucs LE , Brener ND , Waheed F , Jasani S . Health Educ J 2024 Objective: School Health Profiles (Profiles) is a national surveillance system operated by the US Centers for Disease Control and Prevention. A school-based system of surveys, Profiles monitors school health policies and practices in US states and other jurisdictions through questionnaires completed by school principals and lead health education teachers. This study used the Profiles principal survey to identify trends in US schools’ implementation of diversity-related learning opportunities (i.e. opportunities to learn about people who are different from themselves) in secondary school classrooms and extracurricular settings. Methods: Logistic regression models using data from three cycles of School Health Profiles from 35 US states examined trends in the percentages of secondary schools offering students diversity-related learning opportunities in the following settings, each measured by using dichotomous yes/no response options: (a) clubs; (b) lessons in class and (c) special events (e.g. multicultural week, family night) sponsored by the school or community organisations. Results: Between 2014–2018, no states experienced decreases in opportunities for students to learn about people who are different from themselves; most states demonstrated no significant change. Conclusion: Findings suggest efforts are needed to strengthen capacity for and prioritisation of policies, programmes and practices promoting diversity and culturally relevant education in schools, and in turn, promote positive health and educational outcomes for youth. © The Author(s) 2024. |
Trends in the teaching of sexual and reproductive health topics and skills in required courses in secondary schools, in 38 US states between 2008 and 2018
Szucs LE , Demissie Z , Steiner RJ , Brener ND , Lindberg L , Young E , Rasberry CN . Health Educ Res 2022 38 (1) 84-94 Information about state and local education policies regarding sexually transmitted infections, including human immunodeficiency virus, and unintended pregnancy prevention is available, yet less is known about school-level implementation of such policies. We examine trends in the percentage of US secondary schools teaching sexual and reproductive health (SRH) topics in a required course in Grades 6-8 and 9-12, including healthy relationships, sexual abstinence, condoms and condoms with other contraceptive methods. We analyze representative data from 38 states across six cycles of School Health Profiles (2008-18) assessed through self-administered questionnaires completed by lead health teachers. Logistic regression models examined linear trends in the percentages of schools teaching topics for Grades 6-8 and 9-12, separately. Trends were calculated for states having representative data for at least three cycles, including 2018. During 2008-18, it was more common to have increases in teaching how to obtain condoms, correct condom use and use condoms with other contraceptive methods in Grades 6-12 than decreases. More states showed decreases in teaching abstinence in Grades 6-12 than increases. Most states had no change in teaching SRH topics across grades. Findings suggest some improvement in school-based SRH education, yet efforts are needed to improve comprehensive, developmentally appropriate content. |
Trends in teaching sexual and reproductive health skills in US secondary schools in 35 states, 2008 to 2018
Young E , Demissie Z , Brener ND , Benes S , Szucs LE . J Sch Health 2022 92 (7) 711-719 BACKGROUND: Little is known about trends in implementing skills-based instruction in US schools, specifically for sexual and reproductive health (SRH). We examined state-level trends in the percentage of US secondary schools teaching SRH skills in a required course in grades 6 to 8 and 9 to 12. METHODS: Representative data from 35 states participating across 6 cycles of School Health Profiles (2008-2018) was analyzed. The prevalence of teaching four SRH skills was assessed through lead health education teacher self-administered questionnaires. Logistic regression models examined linear trends in the percentages of schools teaching SRH skills in grades 6 to 8 and 9 to 12. Trends were calculated for states with weighted data (response rates ≥70%) for at least 3 cycles, including 2018. RESULTS: During 2008 to 2018, the median percentage of schools addressing each SRH skill ranged from 63.5% to 69.7% (grades 6-8) and 88.2% to 92.0% (grades 9-12). Linear decreases in SRH skills instruction were more common for grades 6 to 8 than grades 9 to 12; linear increases were comparable for both groups. Most states demonstrated no change in the percentage of schools teaching SRH skills in grades 6 to 8 and 9 to 12. CONCLUSIONS: Limited changes and decreases in SRH skills instruction in US secondary schools suggest efforts to strengthen SRH education are needed. |
Hiring requirements and qualifications of school food authority directors changed in some districts after implementation of US Department of Agriculture professional standards
Merlo CL , Tiu G , Wallace-Williams D , Brener ND , Figueroa H . J Acad Nutr Diet 2020 120 (9) 1538-1547 BACKGROUND: In 2015, the US Department of Agriculture set minimum education and training requirements (ie, professional standards) to ensure that school nutrition professionals have the knowledge and experience to operate school meal programs. No study to date has examined whether hiring requirements and qualifications of school food authority (SFA) directors have changed since 2015. OBJECTIVE: To assess changes in hiring requirements and qualifications of SFA directors since the US Department of Agriculture professional standards were established, overall and by district size. DESIGN: Cross-sectional analysis of nationally representative district-level data from the 2012 and 2016 cycles of the School Health Policies and Practices Study. PARTICIPANTS/SETTING: In 2012, 660 sampled districts completed the School Health Policies and Practices Study Nutrition Services questionnaire. In 2016, 599 sampled districts completed the questionnaire. MAIN OUTCOME MEASURES: Hiring requirements for newly hired SFA directors and reported qualifications of SFA directors. STATISTICAL ANALYSES PERFORMED: Differences in prevalence estimates from 2012 to 2016 for all districts and by district size were assessed with χ(2) tests. RESULTS: Significant increases were found for 3 hiring requirements: degree in nutrition or related field, registered dietitian credential, and food safety certification. Significant changes in 4 of the 5 reported qualifications were found including an increase in the percentage of district directors with a degree in nutrition or a related field and decreases in the percentage of directors with a School Nutrition Specialist credential from the School Nutrition Association, School Nutrition Association certifications, and certified dietary managers. Changes were found in small and medium districts, but not large districts. CONCLUSIONS: District hiring requirements and SFA director qualifications have changed since the implementation of the US Department of Agriculture professional standards, including some differences by district size. Future research could identify challenges facing districts in hiring directors who have a degree in nutrition or related fields or who have specialized nutrition credentials or certificates (eg, registered dietitians). |
Characteristics associated with school health services for the management of chronic health conditions
Tiu GF , Leroy ZC , Lee SM , Maughan ED , Brener ND . J Sch Nurs 2019 37 (5) 1059840519884626 It is unknown how health services staff (school nurse or school physician) or school characteristics are associated with the number of services provided for chronic health conditions in schools. Using data from the 2014 School Health Policies and Practices Study, four services (identification or school-based management, tracking, case management, and referrals) were analyzed using a multivariable ordered logistic regression. Approximately 57.2% of schools provided all four, 17.5% provided three, 10.1% provided two, 5.8% provided one, and 9.4% did not provide any such services. Schools with a school nurse were 51.5% (p < .001) more likely to provide all four, and schools with access to consult with a school physician were 15.4% (p < .05) more likely, compared to schools without one. Schools comprised of mostly racial/ethnic minority students (less than or equal to 50% non-Hispanic White) were 14.7% (p < .05) less likely to provide all four, compared to schools with greater than 50% White students. |
State-level guidance and district-level policies and practices for food marketing in US school districts
Merlo CL , Michael S , Brener ND , Blanck H . Prev Chronic Dis 2018 15 E74 State agencies play a critical role in providing school districts with guidance and technical assistance on school nutrition issues, including food and beverage marketing practices. We examined associations between state-level guidance and the policies and practices in school districts regarding food and beverage marketing and promotion. State policy guidance was positively associated with districts prohibiting advertisements for junk food or fast food restaurants on school property. Technical assistance from states was negatively associated with 2 district practices to restrict marketing of unhealthy foods and beverages, but positively associated with 1 practice to promote healthy options. These findings may help inform the guidance that states provide to school districts and help identify which districts may need additional assistance to address marketing and promotion practices. |
Evaluating behavioral health surveillance systems
Azofeifa A , Stroup DF , Lyerla R , Largo T , Gabella BA , Smith CK , Truman BI , Brewer RD , Brener ND . Prev Chronic Dis 2018 15 E53 In 2015, more than 27 million people in the United States reported that they currently used illicit drugs or misused prescription drugs, and more than 66 million reported binge drinking during the previous month. Data from public health surveillance systems on drug and alcohol abuse are crucial for developing and evaluating interventions to prevent and control such behavior. However, public health surveillance for behavioral health in the United States has been hindered by organizational issues and other factors. For example, existing guidelines for surveillance evaluation do not distinguish between data systems that characterize behavioral health problems and those that assess other public health problems (eg, infectious diseases). To address this gap in behavioral health surveillance, we present a revised framework for evaluating behavioral health surveillance systems. This system framework builds on published frameworks and incorporates additional attributes (informatics capabilities and population coverage) that we deemed necessary for evaluating behavioral health-related surveillance. This revised surveillance evaluation framework can support ongoing improvements to behavioral health surveillance systems and ensure their continued usefulness for detecting, preventing, and managing behavioral health problems. |
Do schools that screen for body mass index have recommended safeguards in place
Sliwa SA , Brener ND , Lundeen EA , Lee SM . J Sch Nurs 2018 35 (4) 1059840518758376 The Centers for Disease Control and Prevention recommends that schools adopt 10 safeguards before launching a body mass index (BMI) screening program; however, little is known about schools' safeguard adoption. Authors identified questions from the 2014 School Health Policies and Practices Study that aligned with 4 of the 10 safeguards to estimate safeguard prevalence among schools that screened students for BMI (40.7%, N = 223). Among these schools, 3.1% had all four safeguards and 56.5% had none or one. The most prevalent safeguard was having reliable and accurate equipment (54.1%, 95% confidence interval [CI] = [46.1, 62.1]). Providing staff with appropriate expertise and training was the least prevalent; respondents in 26.4% (95% CI [17.1, 35.6]) of schools received recent training on weight status assessment, weight management, and eating disorder identification. School-based BMI screening is common, but adopting multiple recommended safeguards is not. Absent these safeguards, BMI screening programs may fall short of intended outcomes and potentially incur unintended consequences. |
District policies and practices vary in their association with adolescents' consumption of milk and 100% fruit juice
Sliwa SA , Miller GF , Brener ND , Park S , Merlo CL . J Adolesc Health 2017 60 (5) 577-583 PURPOSE: Researchers previously examined the relationship between school beverage policies and sugar-sweetened beverage (SSB) consumption. This study addressed a research gap by examining cross-sectional associations between district-level policies and practices and U.S. high school students' consumption of milk and 100% fruit juice. METHODS: Data from the 2012 School Health Policies and Practices Study and 2013 Youth Risk Behavior Surveillance System were linked for 12 large urban school districts. Outcome variables were daily milk consumption (≥1 glass/day) and 100% fruit juice consumption (≥1 time/day). Exposure variables were five district policies (i.e., restrict SSB sales, maintain closed campuses, offer/sell healthful alternatives, restrict promotional products, and require nutrition education). Logistic regression models estimated the odds of consuming milk or 100% fruit juice daily, conditional on the policies and adjusting for sex, race/ethnicity, grade level, weight status, and district free/reduced-price lunch eligibility (n = 23,173). RESULTS: Students in districts that required/recommended restricting the times of SSB sales had 55% higher (adjusted odds ratio [AOR], 1.55; 95% confidence interval [CI], 1.28-1.87) odds of consuming ≥1 glass/day of milk than students in districts without this policy. Closed campus policies were associated with lower odds of consuming milk (AOR, .72; 95% CI, .63-.82) and higher odds of consuming juice (AOR, 1.27; 95% CI, 1.07-1.50). Policies requiring/recommending that districts offer/sell healthful alternatives were associated with lower odds of consuming 100% fruit juice daily. CONCLUSIONS: Results suggest that restricting SSB sales may support adolescents' milk consumption. Future studies should assess whether the implementation of federal standards that further restrict SSB sales in school leads to increased milk consumption. |
Differences in food and beverage marketing policies and practices in US school districts, by demographic characteristics of school districts, 2012
Merlo CL , Michael S , Brener ND , Coffield E , Kingsley BS , Zytnick D , Blanck H . Prev Chronic Dis 2016 13 E169 INTRODUCTION: Foods and beverages marketed in schools are typically of poor nutritional value. School districts may adopt policies and practices to restrict marketing of unhealthful foods and to promote healthful choices. Students' exposure to marketing practices differ by school demographics, but these differences have not yet been examined by district characteristics. METHODS: We analyzed data from the 2012 School Health Policies and Practices Study to examine how food and beverage marketing and promotion policies and practices varied by district characteristics such as metropolitan status, size, and percentage of non-Hispanic white students. RESULTS: Most practices varied significantly by district size: a higher percentage of large districts than small or medium-sized districts restricted marketing of unhealthful foods and promoted healthful options. Compared with districts whose student populations were majority (>50%) non-Hispanic white, a higher percentage of districts whose student populations were minority non-Hispanic white (≤50% non-Hispanic white) prohibited advertising of soft drinks in school buildings and on school grounds, made school meal menus available to students, and provided families with information on school nutrition programs. Compared with suburban and rural districts, a higher percentage of urban districts prohibited the sale of soft drinks on school grounds and used several practices to promote healthful options. CONCLUSION: Preliminary findings showing significant associations between district demographics and marketing policies and practices can be used to help states direct resources, training, and technical assistance to address food and beverage marketing and promotion to districts most in need of improvement. |
School district policies and adolescents' soda consumption
Miller GF , Sliwa S , Brener ND , Park S , Merlo CL . J Adolesc Health 2016 59 (1) 17-23 PURPOSE: Sugar-sweetened beverages (SSBs) are a significant source of calories and added sugars for youth ages 14-18 years in the United States. This study examined the relationship between district-level policies and practices and students' consumption of regular soda, one type of SSB, in 12 large urban school districts. METHODS: Data from the 2012 School Health Policies and Practices Study and 2013 Youth Risk Behavior Surveillance System were linked by district. The outcome variable was soda consumption and exposure variables were district policies. We used multivariable logistic regression analyses to calculate adjusted odds ratios (AORs) and 95% confidence intervals (CIs) after controlling for student characteristics and district free/reduced-price meal eligibility. RESULTS: About 18% of students reported consuming regular soda at least once per day. Most districts required high schools to have nutrition education, maintain closed campuses, and required/recommended that schools restrict promotional products and sale of beverages. Fewer districts required/recommended that schools offer healthful alternative beverages. Students in districts that restricted promotional products had lower odds of regular soda consumption (AOR = .84, 95% CI = .71-1.00), as did students in districts that restricted access to SSBs and offered healthful beverages when other beverages were available (AOR = .72, 95% CI = .54-.93, AOR = .76, 95% CI = .63-.91). CONCLUSIONS: This study demonstrates that certain district-level policies are associated with student consumption of regular soda. These findings add to a growing consensus that policies and practices that influence the availability of healthier foods and beverages are needed across multiple settings. |
National and state attitudes of US adults toward tobacco-free school grounds, 2009-2010
Kruger J , Patel R , Kegler MC , Brener ND , King BA . Prev Chronic Dis 2015 12 E229 INTRODUCTION: Schools are an important environment for addressing tobacco use among youth. Tobacco-free school policies can help reduce the social acceptability of tobacco use and prevent tobacco initiation among youth. This study assessed attitudes toward tobacco-free school grounds among US adults. METHODS: Data came from the 2009-2010 National Adult Tobacco Survey, a telephone survey of adults aged 18 or older in the 50 US states and District of Columbia. Respondents were considered to have a favorable attitude toward tobacco-free school grounds if they reported tobacco use should be completely banned on school grounds, including fields and parking lots, and at all school events. Data were assessed using descriptive statistics and multivariable logistic regression, overall and by tobacco use status. Correlates were sex, age, race/ethnicity, education, marital status, income, sexual orientation, US region, and whether respondent lived with any children aged 17 years or younger. RESULTS: Nationally, 86.1% of adults had a favorable attitude toward tobacco-free school grounds, with larger percentages among nontobacco users (91.9%) than current users (76.1%). State prevalence ranged from 80.0% (Kentucky) to 90.9% (Washington). Overall odds of favorable attitudes were higher among nontobacco users (referent, current users), women (referent, men), and adults aged 25 or older (referent, aged 18-24); odds were lower among residents of the South (referent, West) and lesbian, gay, bisexual, or transgender adults (referent, heterosexual or straight). CONCLUSION: Nearly 9 in 10 US adults have a favorable attitude toward tobacco-free school grounds, but attitudes vary across states and subpopulations. Opportunities exist to educate the public about the benefits of tobacco-free school grounds, which might help reduce tobacco use among youth. |
Challenges in and strategies for the surveillance of school health policies and practices: a commentary
Brener ND , Wechsler H , Kann L . J Sch Health 2014 84 (11) 687-9 Since 1994, the Centers for Disease Control and Prevention (CDC) has been monitoring policies and practices across multiple components of school health through 2 surveillance systems: the School Health Policies and Practices Study (SHPPS), a national survey periodically conducted at the state, district, school, and classroom levels, and the School Health Profiles (Profiles), a system of surveys assessing school health policies and practices in states, large urban school districts, territories, and tribal governments. CDC has encountered several challenges in implementing these systems. In this commentary, we describe the most common challenges encountered and the strategies that CDC has identified to address them. We hope our experiences will be helpful to others interested in monitoring school health policies and practices. |
Association between school district policies that address chronic health conditions of students and professional development for school nurses on such policies
Jones SE , Brener ND , Bergren MD . J Sch Nurs 2014 31 (3) 163-6 Supportive school policies and well-prepared school nurses can best address the needs of students with chronic health conditions. We analyzed nationally representative data from the 2012 School Health Policies and Practices Study to examine whether districts with policies requiring that schools provide health services to students with chronic health conditions were more likely to provide funding for professional development (PD) or offer PD to school nurses on those health services than districts without such policies. Compared to districts without certain requirements for health services related to chronic health conditions, districts with those requirements were more likely to provide PD on related topics (for all comparisons, p ≤ .001). For some topics, however, regardless of district requirements, PD was fairly low and suggests the need for increases in the rates at which districts provide PD to support school nurses who deliver services to students with chronic health conditions. |
The relationship between state policies for competitive foods and school nutrition practices in the United States
Merlo CL , Olsen EO , Galic M , Brener ND . Prev Chronic Dis 2014 11 E66 INTRODUCTION: Most students in grades kindergarten through 12 have access to foods and beverages during the school day outside the federal school meal programs, which are called competitive foods. At the time of this study, competitive foods were subject to minimal federal nutrition standards, but states could implement additional standards. Our analysis examined the association between school nutrition practices and alignment of state policies with Institute of Medicine recommendations (IOM Standards). METHODS: For this analysis we used data from the Centers for Disease Control and Prevention's (CDC's) report, Competitive Foods and Beverages in US Schools: A State Policy Analysis and CDC's 2010 School Health Profiles (Profiles) survey to examine descriptive associations between state policies for competitive foods and school nutrition practices. RESULTS: Access to chocolate candy, soda pop, sports drinks, and caffeinated foods or beverages was lower in schools in states with policies more closely aligned with IOM Standards. No association was found for access to fruits or nonfried vegetables. CONCLUSION: Schools in states with policies more closely aligned with the IOM Standards reported reduced access to less healthful competitive foods. Encouraging more schools to follow these standards will help create healthier school environments and may help promote healthy eating among US children. |
Suicidal thoughts and attempts among U.S. high school students: trends and associated health-risk behaviors, 1991-2011
Lowry R , Crosby AE , Brener ND , Kann L . J Adolesc Health 2014 54 (1) 100-8 PURPOSE: To describe secular trends in suicidal thoughts and attempts and the types of health-risk behaviors associated with suicidal thoughts and attempts among U.S. high school students. METHODS: Data were analyzed from 11 national Youth Risk Behavior Surveys conducted biennially during 1991-2011. Each survey employed a nationally representative sample of students in grades 9-12 and provided data from approximately 14,000 students. Using sex-stratified logistic regression models that controlled for race/ethnicity and grade, we analyzed secular trends in the prevalence of suicidal thoughts and attempts. Adjusted prevalence ratios (APR) were calculated to measure associations between suicide risk and a broad range of health-risk behaviors. RESULTS: During 1991-2011, among female students, both suicidal thoughts (seriously considered suicide; made a plan to attempt suicide) and attempts (any attempt; attempt with injury requiring medical treatment) decreased significantly; among male students, only suicidal thoughts decreased significantly. During 2011, compared with students with no suicidal thoughts or attempts, the health-risk behaviors most strongly associated with suicide attempts among female students were injection drug use (APR = 12.8), carrying a weapon on school property (APR = 9.7), and methamphetamine use (APR = 8.7); among male students, the strongest associations were for IDU (APR = 22.4), using vomiting/laxatives for weight control (APR = 17.1), and having been forced to have sex (APR = 14.8). CONCLUSIONS: School-based suicide prevention programs should consider confidential screening for health-risk behaviors that are strongly associated with suicide attempts to help identify students at increased risk for suicide and provide referrals to suicide and other prevention services (e.g., substance abuse and violence prevention) as appropriate. |
Methodology of the Youth Risk Behavior Surveillance System--2013
Brener ND , Kann L , Shanklin S , Kinchen S , Eaton DK , Hawkins J , Flint KH . MMWR Recomm Rep 2013 62 1-20 Priority health-risk behaviors (i.e., interrelated and preventable behaviors that contribute to the leading causes of morbidity and mortality among youths and adults) often are established during childhood and adolescence and extend into adulthood. The Youth Risk Behavior Surveillance System (YRBSS), established in 1991, monitors six categories of priority health-risk behaviors among youths and young adults: 1) behaviors that contribute to unintentional injuries and violence; 2) sexual behaviors that contribute to human immunodeficiency virus (HIV) infection, other sexually transmitted diseases, and unintended pregnancy; 3) tobacco use; 4) alcohol and other drug use; 5) unhealthy dietary behaviors; and 6) physical inactivity. In addition, YRBSS monitors the prevalence of obesity and asthma among this population. YRBSS data are obtained from multiple sources including a national school-based survey conducted by CDC as well as schoolbased state, territorial, tribal, and large urban school district surveys conducted by education and health agencies. These surveys have been conducted biennially since 1991 and include representative samples of students in grades 9-12. In 2004, a description of the YRBSS methodology was published (CDC. Methodology of the Youth Risk Behavior Surveillance System. MMWR 2004;53 [No RR-12]). Since 2004, improvements have been made to YRBSS, including increases in coverage and expanded technical assistance.This report describes these changes and updates earlier descriptions of the system, including questionnaire content; operational procedures; sampling, weighting, and response rates; data-collection protocols; data-processing procedures; reports and publications; and data quality. This report also includes results of methods studies that systematically examined how different survey procedures affect prevalence estimates. YRBSS continues to evolve to meet the needs of CDC and other data users through the ongoing revision of the questionnaire, the addition of new populations, and the development of innovative methods for data collection. |
A comparison of fruit and vegetable intake estimates from three survey question sets to estimates from 24-hour dietary recall interviews
Eaton DK , Olsen EO , Brener ND , Scanlon KS , Kim SA , Demissie Z , Yaroch AL . J Acad Nutr Diet 2013 113 (9) 1165-74 BACKGROUND: Fruit and vegetable (F/V) intake surveillance can provide information critical to the design and evaluation of interventions and the assessment of progress toward national intake objectives. The CDC's Youth Risk Behavior Surveillance System (YRBSS) assesses F/V intake among high school students using six questions about the frequency of intake in times per day. It is not known whether F/V intake frequency in times per day can be used as a proxy for intake in servings per day. OBJECTIVE: To compare F/V intake estimates based on responses to three sets of survey questions, including the standard set of six YRBSS questions, with criterion F/V intake in servings per day based on data from 24-hour dietary recall interviews. PARTICIPANTS/SETTING: Study participants were 610 high school students who completed an in-class questionnaire and three telephone-administered 24-hour dietary recall interviews. The questionnaire asked students how many times they consumed 100% fruit juice and ate fruit, carrots, potatoes, green salad, and other vegetables during the "past 7 days" (set 1), the number of times they did so "yesterday" (set 2), and the number of cup-equivalents of fruits and vegetables they consumed per day (set 3). MAIN OUTCOME MEASURE: Mean estimated F/V intake either as "times/day" or "servings/day" and the percentage of students whose estimated F/V intake was ≥1, ≥2, and ≥3 times/day or servings/day. STATISTICAL ANALYSES PERFORMED: t tests and corrected Pearson correlations were used to compare F/V intake estimates based on survey question responses with estimates based on responses to the 24-hour dietary recall interviews. RESULTS: Mean F/V intake estimates (in times/day or servings/day) based on responses to all sets of survey questions were significantly more than servings/day estimates based on responses to the 24-hour dietary recall interviews, and the percentages of students meeting each intake cutpoint were also more. Of the three sets of survey questions, the standard YRBSS questions produced estimates and percentages that were most consistently closest to 24-hour dietary recall interview estimates. CONCLUSIONS: For brief self-administered questionnaires of high school students, the current YRBSS questions are recommended for monitoring F/V intake even though mean intake estimates in times/day will likely be higher than, and are not a proxy for, mean intake estimates in servings/day. |
Comparing methods for assessing beverage intake among high school students
O'Malley Olsen E , Eaton DK , Park S , Brener ND , Blanck HM . Am J Health Behav 2014 38 (1) 114-23 OBJECTIVES: To compare 7 beverage intake survey questions against criterion data from 24-hour dietary recall interviews (24HrDRIs) among adolescents. METHODS: Data were available from 610 US high school students completing a survey and ≥3 24HrDRIs. Analyses compared mean intake (times/day) calculated from the survey to intake (servings/day) from the 24HrDRIs. Proportions of students reporting intake of ≥1 times/day were compared to the 24HrDRI results. RESULTS: Survey data significantly correlated with 24HrDRI data (all corrected r: 0.26-0.49). Survey results differed from 24HrDRI results on reported intake of 5 beverages. CONCLUSION: Intake from these beverage questions should be reported in times/day, which is related to, but not a proxy for, servings/day. These questions are useful for population-level surveillance of beverage intake and monitoring trends over time. |
Trends in professional development for and collaboration by health education teachers-41 states, 2000-2010
Brener ND , McManus T , Wechsler H , Kann L . J Sch Health 2013 83 (10) 734-42 BACKGROUND: Professional development (PD) and collaboration help ensure the quality of school health education. The purpose of this study was to examine trends in the percentage of lead health education teachers (LHETs) receiving PD on health topics and collaborating with other school staff on health education activities. METHODS: This study analyzed representative data from 41 states participating in School Health Profiles surveys between 2000 and 2010. Logistic regression examined linear trends in the percentage of LHETs who received PD on 12 topics and who collaborated on health education activities. RESULTS: Significant increases in the percentage of LHETs receiving PD on nutrition and physical activity and significant decreases in the percentage of LHETs receiving PD on alcohol- and other drug-use prevention and human immunodeficiency virus prevention were seen. Significant increases in the percentage of LHETs who collaborated with physical education staff and nutrition services staff were seen in 29 and 39 states, respectively. CONCLUSIONS: Although 10-year increases in PD and collaboration in the areas of nutrition and physical activity are encouraging, PD and collaboration in other topic areas still need improvement. These results will help states target more resources toward PD and collaboration in areas where they have been decreasing. |
