Prevalence of adverse childhood experiences among adolescents
Swedo EA , Holditch Niolon P , Anderson KN , Li J , Brener N , Mpofu J , Aslam MV , Underwood JM . Pediatrics 2024 OBJECTIVE: Adverse childhood experiences (ACEs) are preventable, potentially traumatic events with lifelong negative impacts. Population-level data on ACEs among adolescents have historically relied on parent reports and excluded abuse-related ACEs. We present the self-reported prevalence of ACEs among a large population-based sample of US high school students. METHODS: Using cross-sectional, state-representative data from 16 states that included core ACE questions on their 2021 Youth Risk Behavior Survey, we estimate the prevalence of 8 individual (lifetime emotional, physical, or sexual abuse, physical neglect, witnessed intimate partner violence, household substance use, household poor mental health, incarcerated parent or guardian) and cumulative ACEs (0, 1, 2-3, ≥4) among a large population-based sample of adolescents, overall and by demographic characteristics (sex, race and ethnicity, age, sexual orientation). RESULTS: Emotional abuse (65.8%), household poor mental health (36.1%), and physical abuse (32.5%) had the highest prevalence. ACEs were very common, with 80.5% of adolescents experiencing at least 1 ACE and 22.4% experiencing ≥4 ACEs. Experiencing ≥4 ACEs was highest among adolescents who were female (27.7%), non-Hispanic multiracial (33.7%), non-Hispanic American Indian or Alaska Native (27.1%), gay or lesbian (36.5%), bisexual (42.1%), or who described their sexual identity some other way or were not sure of their sexual identity (questioning) (36.5%). CONCLUSIONS: Self-reported ACE estimates among adolescents exceed previously published parent-reported estimates. ACEs are not equally distributed, with important differences in individual and cumulative ACEs by demographic characteristics. Collecting ACE data directly from adolescents at the state level provides actionable data for prevention and mitigation. |
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. |
Overview and methods for the Youth Risk Behavior Surveillance System - United States, 2019
Underwood JM , Brener N , Thornton J , Harris WA , Bryan LN , Shanklin SL , Deputy N , Roberts AM , Queen B , Chyen D , Whittle L , Lim C , Yamakawa Y , Leon-Nguyen M , Kilmer G , Smith-Grant J , Demissie Z , Jones SE , Clayton H , Dittus P . MMWR Suppl 2020 69 (1) 1-10 Health risk behaviors practiced during adolescence often persist into adulthood and contribute to the leading causes of morbidity and mortality in the United States. Youth health behavior data at the national, state, territorial, tribal, and local levels help monitor the effectiveness of public health interventions designed to promote adolescent health. 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. YRBSS includes a nationally representative Youth Risk Behavior Survey (YRBS) and separate state, local school district, territorial, and tribal school-based YRBSs. This overview report describes the surveillance system and the 2019 survey methodology, including sampling, data collection procedures, response rates, data processing, weighting, and analyses presented in this MMWR Supplement. A 2019 YRBS participation map, survey response rates, and student demographic characteristics are included. In 2019, a total of 78 YRBSs were administered to high school student populations across the United States (national and 44 states, 28 local school districts, three territories, and two tribal governments), the greatest number of participating sites with representative data since the surveillance system was established in 1991. The nine reports in this MMWR Supplement are based on national YRBS data collected during August 2018-June 2019. A full description of 2019 YRBS results and downloadable data are available (https://www.cdc.gov/healthyyouth/data/yrbs/index.htm).Efforts to improve YRBSS and related data are ongoing and include updating reliability testing for the national questionnaire, transitioning to electronic survey administration (e.g., pilot testing for a tablet platform), and exploring innovative analytic methods to stratify data by school-level socioeconomic status and geographic location. Stakeholders and public health practitioners can use YRBS data (comparable across national, state, tribal, territorial, and local jurisdictions) to estimate the prevalence of health-related behaviors among different student groups, identify student risk behaviors, monitor health behavior trends, guide public health interventions, and track progress toward national health objectives. |
Experiences of unstable housing among high school students - Youth Risk Behavior Survey, United States, 2021
McKinnon II , Krause KH , Robin L , King A , Leon-Nguyen M , Zavala E , Suarez NA , Lim C , Smith-Grant J , Underwood JM . MMWR Suppl 2023 72 (1) 29-36 Youths experiencing unstable housing face higher risks for poor physical, mental, and sexual health outcomes and increased risk for suicide compared with their peers experiencing stable housing. In addition, youths of color and sexual minority youths are disproportionately more likely to experience homelessness. For the first time, in 2021, the nationally representative Youth Risk Behavior Survey included an item assessing housing stability, or nighttime residence among students in grades 9-12 in the United States. During 2021, 2.7% of U.S. high school students experienced unstable housing. Among racial and ethnic subgroups, Native Hawaiian or other Pacific Islander youths were most likely to experience unstable housing, followed by American Indian or Alaska Native and Black youths. Sexual minority (lesbian, gay, bisexual, and questioning or other) youths were more likely to experience unstable housing compared with their heterosexual peers. Compared with students who were stably housed, students who were unstably housed were more likely to engage in risky sexual behaviors, substance use, and suicide ideation and attempts, and to experience violence. These findings highlight which adverse health risks and behaviors are elevated among youths experiencing housing insecurity. Focused public health interventions are required to address the disproportionate burden of health risks prevalent among youths who are unstably housed. |
Perceived racism and demographic, mental health, and behavioral characteristics among high school students during the COVID-19 pandemic - Adolescent Behaviors and Experiences Survey, United States, January-June 2021
Mpofu JJ , Cooper AC , Ashley C , Geda S , Harding RL , Johns MM , Spinks-Franklin A , Njai R , Moyse D , Underwood JM . MMWR Suppl 2022 71 (3) 22-27 Perceived racism in school (i.e., a student's report of being treated badly or unfairly because of their race or ethnicity) is an important yet understudied determinant of adolescent health and well-being. Knowing how perceived racism influences adolescent health can help reduce health inequities. CDC's 2021 Adolescent Behaviors and Experiences Survey (ABES), an online survey of a probability-based, nationally representative sample of U.S. public- and private-school students in grades 9-12 (N = 7,705), was conducted during January-June 2021 to assess student behaviors during the COVID-19 pandemic. CDC analyzed data from ABES to measure perceived racism and the extent to which perceptions of racism are associated with demographic, mental health, and behavioral characteristics. Mental health and behavioral characteristics analyzed included mental health status; virtual connection with others outside of school; serious difficulty concentrating, remembering, or making decisions; and feeling close to persons at school. Demographic characteristics analyzed included sex, race and ethnicity, and grade. Prevalence of perceived racism and associations between perceived racism and demographic, mental health, and behavioral characteristics are reported overall and stratified by race and ethnicity. Approximately one third (35.6%) of U.S. high school students reported perceived racism. Perceived racism was highest among Asian (63.9%), Black (55.2%), and multiracial students (54.5%). Students who reported perceived racism had higher prevalences of poor mental health (38.1%); difficulty concentrating, remembering, or making decisions (44.1%); and not feeling close to persons at school (40.7%). Perceived racism was higher among those students who reported poor mental health than those who did not report poor mental health during the pandemic among Asian (67.9% versus 40.5%), Black (62.1% versus 38.5%), Hispanic (45.7% and 22.9%), and White students (24.5% versus 12.7%). A better understanding of how negative health outcomes are associated with student experiences of racism can guide training for staff and students to promote cultural awareness and antiracist and inclusivity interventions, which are critical for promoting safe school environments for all students. |
Disruptions to school and home life among high school students during the COVID-19 pandemic - Adolescent Behaviors and Experiences Survey, United States, January-June 2021
Krause KH , Verlenden JV , Szucs LE , Swedo EA , Merlo CL , Niolon PH , Leroy ZC , Sims VM , Deng X , Lee S , Rasberry CN , Underwood JM . MMWR Suppl 2022 71 (3) 28-34 Youths have experienced disruptions to school and home life since the COVID-19 pandemic began in March 2020. During January-June 2021, CDC conducted the Adolescent Behaviors and Experiences Survey (ABES), an online survey of a probability-based, nationally representative sample of U.S. public- and private-school students in grades 9-12 (N = 7,705). ABES data were used to estimate the prevalence of disruptions and adverse experiences during the pandemic, including parental and personal job loss, homelessness, hunger, emotional or physical abuse by a parent or other adult at home, receipt of telemedicine, and difficulty completing schoolwork. Prevalence estimates are presented for all students and by sex, race and ethnicity, grade, sexual identity, and difficulty completing schoolwork. Since the beginning of the pandemic, more than half of students found it more difficult to complete their schoolwork (66%) and experienced emotional abuse by a parent or other adult in their home (55%). Prevalence of emotional and physical abuse by a parent or other adult in the home was highest among students who identified as gay, lesbian, or bisexual (74% emotional abuse and 20% physical abuse) and those who identified as other or questioning (76% and 13%) compared with students who identified as heterosexual (50% and 10%). Overall, students experienced insecurity via parental job loss (29%), personal job loss (22%), and hunger (24%). Disparities by sex and by race and ethnicity also were noted. Understanding health disparities and student disruptions and adverse experiences as interconnected problems can inform school and community initiatives that promote adolescent health and well-being. With community support to provide coordinated, cross-sector programming, schools can facilitate linkages to services that help students address the adverse experiences that they faced during the ongoing COVID-19 pandemic. Public health and health care professionals, communities, schools, families, and adolescents can use these findings to better understand how students' lives have been affected during the pandemic and what challenges need to be addressed to promote adolescent health and well-being during and after the 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. |
Challenging the Association of Marijuana Laws With Teen Marijuana Use
Jones CM , Underwood JM , Volkow ND . JAMA Pediatr 2020 174 (1) 99 To the Editor The debate on effects of state medical and recreational marijuana laws (MMLs/RMLs) is at the forefront of drug policy. Assessing associations of MMLs/RMLs with youth marijuana use is critical given marijuana’s potential for long-term negative effects on brain development and function.1,2 Anderson et al,3 using Youth Risk Behavior Survey (YRBS) data, report MMLs are not associated with youth marijuana use and RMLs are associated with reduced use. However, their analyses include substantial methodologic flaws that may undermine these findings. | | Authors pooled national and state YRBS data from 1993 to 2017. Pooling national and state YRBS data is inappropriate because underlying person-level weights are different, and there is some overlap between national and state YRBS data; thus, a student could be represented more than once. The YRBS codebook explicitly warns against combining these data.4 Authors pulled state data from the national YRBS and used it to assess state MMLs/RMLs. National YRBS data are nationally representative of high school students but not representative of students in a given state. In some cases, only a small number of schools may be selected within a state for the national YRBS, and individual state and school selection to participate in the national YRBS may vary by survey cycle. Authors used unweighted data; YRBS data are designed to be weighted to capture representative populations.4 Establishing that MML/RML implementation occurred before marijuana use reported in 2017 YRBS data is critical. In 2017, 9 states and Washington, DC, legalized recreational marijuana; yet only 4 had marketplaces open the full year. Authors also used binary variables to classify MMLs/RMLs as present or absent and did not account for their significant heterogeneity across states despite prior research documenting the pitfalls of this approach.5 States and Washington, DC, fielded YRBS in the spring or fall of the survey year, yet no information is provided on how survey timing and MML/RML implementation were handled. Results would be skewed if students surveyed before law enactment were combined with those surveyed after enactment in other states. Finally, using cross-sectional data to model RMLs alone on youth marijuana use is problematic; use may have changed after MML enactment, which in some states occurred a decade before RML passage. A more sophisticated approach would model effects of MMLs/RMLs on marijuana use accounting for timing of law implementation. | | We commend the authors for evaluating potential effects of MMLs/RMLs. However, the significant methodologic flaws described here compel us to question the validity of their findings. |
Health-risk behaviors and experiences among Asian American and native Hawaiian/Pacific Islander adolescents in the United States, 2011-2019
Swaminath M , Clayton HB , Lowry R , Hertz M , Underwood JM . Public Health Rep 2023 138 (6) 333549221137325 OBJECTIVES: Understanding the health-risk behaviors of racial and ethnic groups when disaggregated is an important step in improving the health outcomes of racial and ethnic minority groups. We compared national prevalence estimates for selected health-risk behaviors and experiences of Asian American and Native Hawaiian/Pacific Islander (NHPI) students with those of non-Hispanic White, non-Hispanic Black, and Hispanic students. METHODS: We analyzed data from the Youth Risk Behavior Survey, a nationally representative survey of US high school students. To generate a sufficient sample of Asian American and NHPI students for analyses, we combined data from 5 survey administrations, conducted in 2011, 2013, 2015, 2017, and 2019 (N = 73 074). We calculated the prevalence and 95% CIs; we analyzed data on Asian American and NHPI adolescents separately to unmask important differences. RESULTS: Compared with students of other races and ethnicities, Asian American students had the lowest prevalence of alcohol use (16.7%) and marijuana use (10.3%). In contrast, NHPI students were more likely than Asian American students to participate in several health-risk behaviors and experiences, such as substance use (ranging from 4.8% for ever injecting an illegal drug to 31.5% for current alcohol use), having been in a physical fight (15.4%), and having been threatened or injured with a weapon (11.6%). Differential patterns in the prevalence of ever having missed school due to feeling unsafe among NHPI and Asian American students were observed among male and female students. CONCLUSION: Further disaggregating racial subgroups within broad categories of Asian American and NHPI populations may reveal differences from overall group prevalence, and additional strategies to identify these differences should be investigated. |
The increasing utility of school health data to guide evidence-based interventions
Smith Grant J , Pierre K , Stinson J , Thornton J , Mpofu JJ , Rasberry CN , Sims VM , Underwood JM . J Sch Health 2022 92 (12) 1214-1216 The Centers for Disease Control and Prevention's (CDC) Division of Adolescent and School Health (DASH) works with local decision makers, schools, youth-serving organizations, and parents across the nation to equip youth with knowledge, skills, and resources needed for healthy adolescence and adulthood. Aligned with this effort, DASH maintains high-quality surveillance systems to understand youth health behaviors and assess school health programs and policies. The Youth Risk Behavior Surveillance System (YRBSS) is a system of surveys administered every other year to high school students. In addition to the national Youth Risk Behavior Survey conducted by CDC, YRBSS features Youth Risk Behavior Surveys (YRBS) conducted by state, territorial, and local education and health agencies and tribal governments across the nation.1 Local decision makers collaborate with partners to develop questionnaires for their respective YRBS, then coordinate data dissemination and utilization. Since its inception in 1991, YRBSS has collected data from more than 5 million high school students in approximately 2200 separate surveys across the United States.1 The School Health Profiles (Profiles) is a system of surveys conducted by state, territorial, and local education and health agencies and tribal governments. These surveys collect data every other year from principals and lead health education teachers to assess school-implemented health programs and policies.2 Since 1994, Profiles data have helped evaluate health programs and informed professional development needs for educators in middle and high schools.2 Together, YRBSS and Profiles offer metrics to inform public health needs, which are then translated into evidence-based programs to protect youth. |
Racial-ethnic disparities in adolescent sexual behaviours: the cross-sectional Youth Risk Behavior Survey, 2009-19
Demissie Z , Ethier K , Williams K , Dunville R , Cavalier Y , Payne R , Underwood JM . Sex Health 2022 19 (5) 456-463 BACKGROUND: There are notable disparities by race/ethnicity in the sexual health of US adolescents and young adults. Our objective was to examine change over time in racial-ethnic disparities in sexual behaviours among US high school students. METHODS: Data were analysed from six biennial cycles of the national Youth Risk Behavior Survey (2009-19), conducted among cross-sectional, nationally representative samples of 9th-12th grade students. Data were collected via self-administered questionnaires. Multivariable logistic regression models tested for linear trends by race/ethnicity (White, Black, Hispanic) and differences in these trends in: ever had sex, current sexual activity, having four or more lifetime sexual partners, and condomless sex. Prevalence ratios and risk differences by race/ethnicity for each cycle were used to calculate average percent change in the estimates to determine if health disparities changed over time. RESULTS: During 2009-19, prevalence estimates for ever had sex, current sexual activity, and having four or more lifetime sexual partners decreased overall and across all racial-ethnic groups. For condomless sex, prevalence estimates increased over time overall (38.9-45.7%) and for Black (37.6-51.8%) and White (36.7-44.2%) students, but not Hispanic (45.1-43.8%) students. Significant differences in trends by race/ethnicity were observed for all variables. Data suggest that racial-ethnic health disparities for sexual behaviours decreased over time, except for condomless sex. CONCLUSIONS: Although racial-ethnic gaps in sexual behaviours may be shrinking for many behaviours, work is still needed to achieve health equity in risks associated with HIV/AIDS, sexually transmitted infections, and pregnancy. |
At the intersections: Examining trends in experiences of violence, mental health status, and suicidal risk behaviors among US high school students using intersectionality, National Youth Risk Behavior Survey, 2015-2019
Krause KH , Mpofu J , Brown M , Rico A , Andrews C , Underwood JM . J Adolesc Health 2022 71 (3) 293-300 PURPOSE: Surveillance data are used for public health action, but the practice of analyzing data by single demographic characteristics may produce findings that reflect abstract categories rather than a person's lived experience. Intersectionality is a theoretical framework that advocates for individuals to be recognized as the whole of their identity and within context of power structures. Using the national Youth Risk Behavior Survey 2015-2019, we examined 5-year trends in experiencing violence, poor mental health, and suicidal risk behavior among US high school students using intersections of race/ethnicity and sex. METHODS: We used SUDAAN to calculate prevalence estimates and logistic regression models to assess for linear trends while accounting for the weighting and complex survey design. RESULTS: Among all students in aggregate, experiencing dating violence decreased while being threatened with a weapon at school and feeling persistently sad or hopeless increased over time; however, these trends did not apply to most students when stratified by identity. The one near-universal experience was that students in aggregate and almost all identities had an increased trend of skipping school because they felt unsafe there. DISCUSSION: By focusing on identities defined by two main drivers of health disparities-race/ethnicity and sex-we found that changes in risk behaviors did not occur equally among students and that prevalence estimates were highest among Black males, Black females, and Hispanic females. We outlined the power structures that frame the current educational environment. Patterns of health disparities can be highlighted by analyzing surveillance data through an intersectional lens. |
Electronic versus paper and pencil survey administration mode comparison: 2019 Youth Risk Behavior Survey
Bryan LN , Smith-Grant J , Brener N , Kilmer G , Lo A , Queen B , Underwood JM . J Sch Health 2022 92 (8) 804-811 BACKGROUND: Since the inception of the Youth Risk Behavior Surveillance System in 1991, all surveys have been conducted in schools, using paper and pencil instruments (PAPI). For the 2019 YRBSS, sites were offered the opportunity to conduct their surveys using electronic data collection. This study aimed to determine whether differences in select metrics existed between students who completed the survey electronically versus using PAPI. METHODS: Thirty risk behaviors were examined in this study. Data completeness, response rates and bivariate comparisons of risk behavior prevalence between administration modes were examined. RESULTS: Twenty-nine of 30 questions examined had more complete responses among students using electronic surveys. Small differences were found for student and school response rates between modes. Twenty-five of 30 adolescent risk behaviors showed no mode effect. CONCLUSIONS: Seven of 44 states and DC participated electronically. Because survey data were more complete; school and student response rates were consistent; and minor differences existed in risk behaviors between modes, the acceptability of collecting data electronically was demonstrated. |
The CDC's Adolescent Behaviors and Experiences Survey - Using Intersectionality and School Connectedness to Understand Health Disparities During the COVID-19 Pandemic.
Krause KH , Mpofu JJ , Underwood JM , Ethier KA . J Adolesc Health 2022 70 (5) 703-705 In March 2020, schools across the United States closed to reduce the transmission of SARS-CoV-2, the virus that causes COVID-19. As a result, youth experienced disruptions to their academic, social, and emotional support systems. In the spring and summer of 2020, high profile incidents of abject racism (highlighted by the murder of George Floyd, an unarmed black man killed by white police officers) led to racial tension, societal unrest, protests, and unprecedented levels of emotional distress among the US population [1]. School closures drastically limited the availability of services, such as meals and health services, as well as important connections to peers and supportive adults in the school setting. By late 2020, studies began to show that families with school-age youth were struggling with economic and food insecurity, with a greater burden among Black and Hispanic families and families with low income [2]. Many youths experienced poor mental health [3] and violence at home [4]. For a more comprehensive understanding of how the COVID-19 pandemic impacted student health and well-being, CDC administered the Adolescent Behaviors and Experiences Survey (ABES) among a nationally representative sample of high school students (grades 912) sampled through their schools JanuaryJune 2021 [5]. |
Risk Behaviors and Experiences Among Youth Experiencing Homelessness-Youth Risk Behavior Survey, 23 U.S. States and 11 Local School Districts,2019
Smith-Grant J , Kilmer G , Brener N , Robin L , Underwood JM . J Community Health 2022 47 (2) 324-333 Youth experiencing homelessness experience violence victimization, substance use, suicide risk, and sexual risk disproportionately, compared with their stably housed peers. Yet few large-scale assessments of these differences among high school students exist. The youth risk behavior survey (YRBS) is conducted biennially among local, state, and nationally representative samples of U.S. high school students in grades 9-12. In 2019, 23 states and 11 local school districts included a measure for housing status on their YRBS questionnaire. The prevalence of homelessness was assessed among states and local sites, and relationships between housing status and violence victimization, substance use, suicide risk, and sexual risk behaviors were evaluated using logistic regression. Compared with stably housed students, students experiencing homelessness were twice as likely to report misuse of prescription pain medicine, three times as likely to be threatened or injured with a weapon at school, and three times as likely to report attempting suicide. These findings indicate a need for intervention efforts to increase support, resources, and services for homeless youth. |
Individual and Collective Positive Health Behaviors and Academic Achievement Among U.S. High School Students, Youth Risk Behavior Survey 2017
Hawkins GT , Lee SH , Michael SL , Merlo CL , Lee SM , King BA , Rasberry CN , Underwood JM . Am J Health Promot 2021 36 (4) 8901171211064496 PURPOSE: We examined associations between academic grades and positive health behaviors, individually and collectively, among U.S. high school students. DESIGN: Cross-sectional study design. SETTING: Data were from the 2017 national Youth Risk Behavior Survey. Response rates were 75% for schools, 81% for students, and 60% overall (n = 14,765 students). SUBJECTS: Youth in grades 9th-12th. MEASURES: We focused on youth behaviors that can prevent or delay the onset of chronic health conditions. Seven dietary, 3 physical activity, 2 sedentary screen time, and 4 tobacco product use behaviors were assessed. Variables were dichotomized (0/1) to indicate that a score was given to the positive health behavior response (e.g.,, did not smoke cigarettes = 1). A composite score was created by summing each positive health behavior response among 16 total health behaviors. ANALYSIS: Multivariable logistic regression analyses for each individual health behavior, and a multivariable negative binomial regression for the composite score, were conducted with self-reported academic grades, controlling for sex, grade in school, race/ethnicity, and body mass index (BMI) categories. RESULTS: Controlling for covariates, students who reported mostly A's had 2.0 (P < .001) more positive health behaviors; students who reported mostly B's had 1.3 (P < .001) more positive health behaviors; and students who reported mostly C's had .78 (P < .001) more positive health behaviors, compared to students who reported mostly D's/F's. CONCLUSIONS: Higher academic grades are associated with more positive individual and cumulative health behaviors among high school students. Understanding these relationships can help inform efforts to create a healthy and supportive school environment and strive for health equity. |
School-level poverty and rurality associated with differences in sexual risk behaviors among U.S. public high school students
Underwood JM , Pampati S , Everett Jones S , Bryan LN , Demissie Z , Cavalier Y , Rasberry CN . J Adolesc Health 2021 69 (6) 964-969 PURPOSE: This study examined associations between student sexual behaviors and both school-level socioeconomic status and metropolitan status. METHODS: National Youth Risk Behavior Survey data from 2017 (N = 14,765, response rate = 60%) and 2019 (N = 13,677, 60%) were combined. School-level socioeconomic status (low-, mid-, and high-poverty based on the percentage of students eligible for free or reduced-price meals) and metropolitan status (urban, suburban/town, or rural) were identified for students attending public high schools. Sexual behaviors included currently sexually active, four or more lifetime sexual partners, condom use during the last sexual intercourse, hormonal birth control use during the last sexual intercourse, condom and hormonal birth control use during the last sexual intercourse, and drank alcohol or used drugs before the last sexual intercourse. Adjusted prevalence ratios were calculated using logistic regression models, controlling for sex, race/ethnicity, and grade. RESULTS: Compared to students attending low-poverty schools, high-poverty school students were significantly more likely to be currently sexually active (adjusted prevalence ratio = 1.4 [95% confidence interval = 1.1-1.8]) and have four or more lifetime sexual partners (1.6 [1.0-2.5]), but were significantly less likely to have drank alcohol or used drugs before the last sexual intercourse (.7 [.5-.9]) and have used hormonal birth control during the last sexual intercourse (.7 [.6-1.0]). Compared to students attending rural schools, urban school students were significantly less likely to be currently sexually active (.8 [.7-.9]) and have four or more lifetime sexual partners (.7 [.5-.9]). CONCLUSIONS: School-level socioeconomic status and metropolitan status were associated with differential risk in sexual behaviors. |
Health Risk Behaviors, Experiences, and Conditions Among Students Attending Private and Public High Schools
Deputy NP , Bryan L , Lowry R , Brener N , Underwood JM . J Sch Health 2021 91 (9) 683-696 BACKGROUND: Approximately 8.8% of US high school students attended private schools in 2015. Few studies have characterized health risk behaviors among these students or compared prevalence of behaviors between students in private and public schools using a contemporary, nationally representative sample. METHODS: Pooled 2007-2017 national Youth Risk Behavior Survey data were used to estimate the prevalence of 35 health risk behaviors for 89,848 public and private high school students. Unadjusted prevalence ratios were used to compare prevalence by school type. Differences in behaviors by school type were explored by sex and grade. RESULTS: Among private school students, the prevalence ranged from 5.0% to 31.9% for sexual risk behaviors; from 0.8% to 30.1% for substance use behaviors; from 0.7% to 21.8% for behaviors related mental health and suicide; from 3.2% to 6.8% for violence victimization experiences; and from 3.1% to 52.9% for behaviors related to unhealthy diet and physical inactivity. Private school students were less likely than public school students to report most behaviors; differences by school type were generally consistent across sex and grade. CONCLUSIONS: Students in both public and private schools reported health risk behaviors. Findings might inform prevention activities by identifying behaviors to prioritize in each school setting. |
US nationwide assessment of school health policies and practices using state-level data
Bryan LN , Brener N , Barker L , Lo A , Underwood JM . Health Educ J 2021 80 (6) 724-733 Objective: After the discontinuation of School Health Policies and Practices Study (SHPPS) in 2016, the US Centers for Disease Control and Prevention (CDC) began exploring innovative ways to gather school health information using existing surveillance systems. School Health Profiles (Profiles) is a school-based system of surveys that monitors school health policies and practices in states and other jurisdictions. The objective of this study was to assess whether prevalence estimates calculated using nationally representative SHPPS as an established benchmark were similar to estimates using aggregated Profiles data. Method: Nationwide 2014 Profiles estimates were calculated from data across all 50 US states and the District of Columbia and compared to national 2014 SHPPS estimates. Fifty-seven questions were identical between the data sources. Equivalence tests were used to determine similarity between data sources. Results: Overall, the median difference between 2014 SHPPS and 2014 Profiles estimate was one percentage point and distribution-free 95% confidence intervals were (−0.8, 3.1). Of the 57 school health policy and practice indicators examined in this study, 38 (66.7%) were found to be equivalent. Of these equivalent indicators, the median percentage point difference between data sources was 0.8 (−0.8, 2.5). A nonparametric sign test showed that none of the medians of the estimate differences examined were significantly different from zero. Conclusion: This study demonstrates the expanded utility of state-level data to meet public health surveillance needs. This study found that aggregated, state-level Profiles data can be used to calculate nationwide prevalence estimates that are reasonably consistent with results from a nationally representative survey. © The Author(s) 2021. |
Amplifying improvements in the Centers for Disease Control and Prevention Youth Risk Behavior Surveillance System
Underwood JM , Brener N , Ford CA . J Adolesc Health 2020 67 (3) 338-339 The Centers for Disease Control and Prevention (CDC) Youth Risk Behavior Surveillance System (YRBSS) monitors trends in adolescent health-related behaviors and experiences that contribute to the leading causes of death and disability among youth and adults in the U.S. Administered in high schools, YRBSS is the nation's largest surveillance system dedicated to monitoring adolescent health behaviors, and data are used to track student risk behaviors and guide school health programs across states and local jurisdictions [1]. During the 2019 YRBSS cycle, CDC led efforts to reach more jurisdictions, advance data collection methods, ensure representativeness to accurately reflect student populations, and incorporate innovative approaches to data dissemination. The structural improvements made during the 2019 YRBSS cycle align with CDC's surveillance modernization efforts to increase data quality and utilization [2]. In this commentary, we describe improvements in YRBSS methodology and announce the periodic publication of featured YRBSS findings in the Journal of Adolescent Health. |
Centers for Disease Control and Prevention's School Vaccination Assessment: Collaboration with US state, local, and territorial immunization programs, 2012-2018
Mellerson JL , Street E , Knighton C , Calhoun K , Seither R , Underwood JM . Am J Public Health 2020 110 (7) e1-e6 Objectives. To describe the ongoing collaboration of the Centers for Disease Control and Prevention's (CDC's) school vaccination assessment with state, local, and territorial immunization programs to provide data to monitor school entry vaccination.Methods. Departments of health and education partner to collect data from public school, private school, and homeschooled kindergartners in the 50 US states, the District of Columbia, 2 cities, and the US territories. Immunization programs submit vaccination coverage and exemption data to the CDC, and the CDC reports these data annually via multiple sources.Results. Among the 50 states and the District of Columbia, the number of programs using a census for vaccination coverage data increased from 39 to 41 during the school years 2012-2013 to 2017-2018 (which for most states was August or September through May or June), and the number using a census to collect exemption data increased from 40 to 46. The number of states that reported sharing their local-level vaccination coverage data online increased from 11 in 2012-2013 to 31 in 2017-2018.Conclusions. Coverage data can be used to address undervaccination among kindergartners to work with communities and schools that are susceptible to vaccine-preventable diseases. As more states publish local-level data online, access to improved data provides the public more valuable information. (Am J Public Health.

Vaccination-related activities at schools with kindergartners: Evidence from a school nurse survey
Leidner AJ , Maughan ED , Bjork A , Black C , Mazyck D , Underwood JM . J Sch Nurs 2019 36 (6) 1059840519847730 Vaccination coverage among children in kindergarten varies across the country and within states. We surveyed a convenience sample of kindergarten school nurses to investigate self-reported vaccination-related activities conducted at schools nationwide. The majority of the 1,435 kindergarten school nurses responding reported that their schools communicate with parents and guardians of undervaccinated students by phone (96%), postal mail (67%), newsletters (61%), and e-mail (59%). Most respondents reported documenting vaccination coverage in electronic systems (85%) and sharing coverage reports with health departments (69%). A total of 41% of school nurses worked with external partners for vaccination efforts, the most common support received from partners being vaccine administration (38%) and providing materials/vaccines (21%). School nurses also reported that 95% of kindergartners were up to date for all vaccines. School-based vaccination-related activities are essential to sustaining high levels of vaccination coverage for the protection of children at schools and in the broader community. |
Transgender identity and experiences of violence victimization, substance use, suicide risk, and sexual risk behaviors among high school students - 19 states and large urban school districts, 2017
Johns MM , Lowry R , Andrzejewski J , Barrios LC , Demissie Z , McManus T , Rasberry CN , Robin L , Underwood JM . MMWR Morb Mortal Wkly Rep 2019 68 (3) 67-71 Transgender youths (those whose gender identity* does not align with their sex(dagger)) experience disparities in violence victimization, substance use, suicide risk, and sexual risk compared with their cisgender peers (those whose gender identity does align with their sex) (1-3). Yet few large-scale assessments of these disparities among high school students exist. The Youth Risk Behavior Survey (YRBS) is conducted biennially among local, state, and nationally representative samples of U.S. high school students in grades 9-12. In 2017, 10 states (Colorado, Delaware, Hawaii, Maine, Maryland, Massachusetts, Michigan, Rhode Island, Vermont, Wisconsin) and nine large urban school districts (Boston, Broward County, Cleveland, Detroit, District of Columbia, Los Angeles, New York City, San Diego, San Francisco) piloted a measure of transgender identity. Using pooled data from these 19 sites, the prevalence of transgender identity was assessed, and relationships between transgender identity and violence victimization, substance use, suicide risk, and sexual risk behaviors were evaluated using logistic regression. Compared with cisgender males and cisgender females, transgender students were more likely to report violence victimization, substance use, and suicide risk, and, although more likely to report some sexual risk behaviors, were also more likely to be tested for human immunodeficiency virus (HIV) infection. These findings indicate a need for intervention efforts to improve health outcomes among transgender youths. |
Vaccination coverage among children aged 2 years - U.S. Affiliated Pacific Islands, April-October, 2016
Tippins A , Murthy N , Meghani M , Solsman A , Apaisam C , Basilius M , Eckert M , Judicpa P , Masunu Y , Pistotnik K , Pedro D , Sasamoto J , Underwood JM . MMWR Morb Mortal Wkly Rep 2018 67 (20) 579-584 Vaccine-preventable diseases (VPDs) cause substantial morbidity and mortality in the United States Affiliated Pacific Islands (USAPI).* CDC collaborates with USAPI immunization programs to monitor vaccination coverage. In 2016, (dagger) USAPI immunization programs and CDC piloted a method for estimating up-to-date status among children aged 2 years using medical record abstraction to ascertain regional vaccination coverage. This was the first concurrent assessment of childhood vaccination coverage across five USAPI jurisdictions (American Samoa; Chuuk State, Federated States of Micronesia [FSM]; Commonwealth of the Northern Mariana Islands [CNMI]; Republic of the Marshall Islands [RMI]; and Republic of Palau).( section sign) Differences in vaccination coverage between main and outer islands( paragraph sign) were assessed for two jurisdictions where data were adequate.** Series coverage in this report includes the following doses of vaccines: >/=4 doses of diphtheria and tetanus toxoids and acellular pertussis vaccine (DTaP); >/=3 doses of inactivated poliovirus vaccine (IPV); >/=1 dose of measles, mumps, and rubella vaccine (MMR); >/=3 doses of Haemophilus influenzae type B (Hib) vaccine; >/=3 doses of hepatitis B (HepB) vaccine; and >/=4 doses of pneumococcal conjugate vaccine (PCV); i.e., 4:3:1:3:3:4. Coverage with >/=3 doses of rotavirus vaccine was also assessed. Completion of the recommended series of each of these vaccines(daggerdagger) was <90% in all jurisdictions except Palau. Coverage with the full recommended six-vaccine series (4:3:1:3:3:4) ranged from 19.5% (Chuuk) to 69.1% (Palau). In RMI and Chuuk, coverage was lower in the outer islands than in the main islands for most vaccines, with differences ranging from 0.9 to 66.8 percentage points. Medical record abstraction enabled rapid vaccination coverage assessment and timely dissemination of results to guide programmatic decision-making. Effectively monitoring vaccination coverage, coupled with implementation of data-driven interventions, is essential to maintain protection from VPD outbreaks in the region and the mainland United States. |
Timeliness of childhood vaccination in the Federated States of Micronesia
Tippins A , Leidner AJ , Meghani M , Griffin A , Helgenberger L , Nyaku M , Underwood JM . Vaccine 2017 35 (47) 6404-6411 BACKGROUND: Vaccination coverage is typically measured as the proportion of individuals who have received recommended vaccine doses by the date of assessment. This approach does not provide information about receipt of vaccines by the recommended age, which is critical for ensuring optimal protection from vaccine-preventable diseases (VPDs). OBJECTIVE: To assess vaccination timeliness in the Federated States of Micronesia (FSM), and the projected impact of suboptimal vaccination in the event of an outbreak. METHODS: Timeliness of the 4th dose of diphtheria, tetanus, and acellular pertussis vaccine (DTaP) and 1st dose of measles, mumps, and rubella vaccine (MMR) among children 24-35 months was assessed in FSM. Both doses are defined as on time if administered from 361 through 395 days in age. Timeliness was calculated by one-way frequency analysis, and dose delays, measured in months after recommended age, were described using inverse Kaplan-Meier analysis. A time-series susceptible-exposed-infected-recovery (TSEIR) model simulated measles outbreaks in populations with on time and late vaccination. RESULTS: Total coverage for the 4th dose of DTaP ranged from 36.6% to 98.8%, and for the 1st dose of MMR ranged from 80.9% to 100.0% across FSM states. On time coverage for the 4th dose of DTaP ranged from 3.2% to 52.3%, and for the 1st dose of MMR ranged from 21.1% to 66.9%. Maximum and median dose delays beyond the recommended age varied by state. TSEIR models predicted 10.8-13.7% increases in measles cases during an outbreak based on these delays. CONCLUSIONS: In each of the FSM states, a substantial proportion of children received DTaP and MMR doses outside the recommended timeframe. Children who receive vaccinations later than recommended remain susceptible to VPDs during the period they remain unvaccinated, which may have a substantial impact on health systems during an outbreak. Immunization programs should consider vaccination timeliness in addition to coverage as a measure of susceptibility to VPDs in young children. |
Vaccination coverage for selected vaccines, exemption rates, and provisional enrollment among children in kindergarten - United States, 2016-17 school year
Seither R , Calhoun K , Street EJ , Mellerson J , Knighton CL , Tippins A , Underwood JM . MMWR Morb Mortal Wkly Rep 2017 66 (40) 1073-1080 State and local school vaccination requirements help protect students and communities against vaccine-preventable diseases (1). CDC reports vaccination coverage and exemption data for children attending kindergarten (kindergartners) collected by federally funded immunization programs in the United States.* The typical age range for kindergartners is 4-6 years. Although vaccination requirements vary by state (the District of Columbia [DC] is counted as a state in this report.), the Advisory Committee on Immunization Practices recommends that children in this age range have received, among other vaccinations, 5 doses of diphtheria, tetanus, and acellular pertussis vaccine (DTaP), 2 doses of measles, mumps, and rubella vaccine (MMR), and 2 doses of varicella vaccine (2). This report summarizes 2016-17 school year MMR, DTaP, and varicella vaccination coverage reported by immunization programs in 49 states, exemptions in 50 states, and kindergartners provisionally enrolled or within a grace period in 27 states. Median vaccination coveragedagger was 94.5% for the state-required number of doses of DTaP; 94.0% for 2 doses of MMR; and 93.8% for 2 doses of varicella vaccine. The median percentage of kindergartners with an exemption from at least one vaccine section sign was 2.0%, similar to 2015-16 (1.9%). Median grace period and provisional enrollment was 2.0%. Vaccination coverage remains consistently high and exemptions low at state and national levels. Local-level vaccination coverage data provide opportunities for immunization programs to identify schools, districts, counties, or regions susceptible to vaccine-preventable diseases and for schools to address undervaccination through implementation of existing state and local vaccination policies (1) to protect communities through increased coverage. |
Cost of a measles outbreak in a remote island economy: 2014 Federated States of Micronesia measles outbreak
Pike J , Tippins A , Nyaku M , Eckert M , Helgenberger L , Underwood JM . Vaccine 2017 35 (43) 5905-5911 After 20 years with no reported measles cases, on May 15, 2014 the Centers for Disease Control and Prevention (CDC) was notified of two cases testing positive for measles-specific immunoglobulin M (IgM) antibodies in the Federated States of Micronesia (FSM). Under the Compact of Free Association, FSM receives immunization funding and technical support from the United States (US) domestic vaccination program managed by the Centers for Disease Control and Prevention (CDC). In a collaborative effort, public health officials and volunteers from FSM and the US government worked to respond and contain the measles outbreak through an emergency mass vaccination campaign, contact tracing, and other outbreak investigation activities. Contributions were also made by United Nations Children's Emergency Fund (UNICEF) and World Health Organization (WHO). Total costs incurred as a result of the outbreak were nearly $4,000,000; approximately $10,000 per case. Direct medical costs ( approximately $141,000) were incurred in the treatment of those individuals infected, as well as lost productivity of the infected and informal caregivers ( approximately $250,000) and costs to contain the outbreak ( approximately $3.5 million). We assessed the economic burden of the 2014 measles outbreak to FSM, as well as the economic responsibilities of the US. Although the US paid the majority of total costs of the outbreak ( approximately 67%), examining each country's costs relative to their respective economy illustrates a far greater burden to FSM. We demonstrate that while FSM was heavily assisted by the US in responding to the 2014 Measles Outbreak, the outbreak significantly impacted their economy. FSM's economic burden from the outbreak is approximately equivalent to their entire 2016 Fiscal Year budget dedicated to education. |
