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. |
Interpersonal violence victimization among high school students - Youth Risk Behavior Survey, United States, 2019
Basile KC , Clayton HB , DeGue S , Gilford JW , Vagi KJ , Suarez NA , Zwald ML , Lowry R . MMWR Suppl 2020 69 (1) 28-37 Adolescent interpersonal violence victimization is an adverse childhood experience and a serious public health problem for youths, their families, and communities. Violence victimization includes dating violence, sexual violence, and bullying. Youth Risk Behavior Survey data for 2019 were used to examine physical and sexual dating violence; sexual violence by anyone; and bullying victimization, whether on school property or electronic, of U.S. high school students by sex, race/ethnicity, and sexual identity. In addition, this report explores frequency of dating violence and frequency of sexual violence among students who reported these forms of victimization and presents composites of dating violence and bullying. Findings reveal that 8.2% of students reported physical dating violence; 8.2% reported sexual dating violence; 10.8% reported sexual violence by anyone, of which 50% of cases were by a perpetrator other than a dating partner; 19.5% reported bullying on school property; and 15.7% reported electronic bullying victimization during the previous 12 months. Approximately one in eight students reported any dating violence, and one in four reported any bullying victimization. Female students; lesbian, gay, and bisexual students; and students not sure of their sexual identity reported the highest prevalence estimates across all five violence victimization types, any and both forms of dating violence, and any bullying victimization. Non-Hispanic white students reported the highest prevalence of bullying victimization. Among students experiencing physical or sexual dating violence or sexual violence by anyone, the most common frequency reported was one time during the previous year; higher frequency was more prevalent among male students compared with female students. These findings provide a contextual understanding of the prevalence of interpersonal violence of U.S. high school students, highlighting those with highest prevalence. Findings can be used by public health professionals to guide prevention efforts with youths in schools and communities. |
Dating violence, sexual violence, and bullying victimization among high school students -Youth Risk Behavior Survey, United States, 2021
Clayton HB , Kilmer G , DeGue S , Estefan LF , Le VD , Suarez NA , Lyons BH , Thornton JE . MMWR Suppl 2023 72 (1) 66-74 Experiences of teen dating violence (TDV), sexual violence, and bullying during adolescence are all forms of interpersonal violence victimization (IVV) and are associated with health and behavioral issues during adulthood. Data from the nationally representative 2011-2021 Youth Risk Behavior Surveys were used to estimate the 2021 prevalence of IVV reported by U.S. high school students. IVV included past-year sexual TDV, physical TDV, sexual violence by anyone, electronic bullying, being bullied on school property, and lifetime forced sex and was analyzed by demographic characteristics and sex of sexual contacts. This report also explored trends in IVV over this 10-year period among U.S. high school students. In 2021, a total of 8.5% of students reported physical TDV, 9.7% reported sexual TDV, 11.0% reported sexual violence by anyone (with 59.5% of those also reporting sexual TDV), 15.0% reported bullying on school property, and 15.9% reported electronic bullying victimization during the past 12 months; 8.5% also reported experiencing forced sex in their lifetime. Disparities were observed for each form of IVV assessed for females and for most forms of IVV among racial and ethnic minority students; students who identified as lesbian, gay, bisexual, questioning, or other (LGBQ+); and students who reported their sexual contacts as same sex only or both sexes. Trend analyses indicated that physical TDV, sexual TDV, any physical or sexual TDV, and both physical and sexual TDV victimization decreased from 2013 to 2021 (although sexual TDV increased from 2019 to 2021). Any bullying victimization decreased from 2011 to 2021. Lifetime forced sexual intercourse decreased from 2011 to 2015, then increased from 2015 to 2021. Being bullied on school property was unchanged from 2011 to 2017, then decreased from 2017 to 2021. Sexual violence by anyone increased from 2017 to 2021. This report highlights disparities in IVV and provides the first national estimates among Native Hawaiian or other Pacific Islander youths. Findings, including trend analyses indicating recent increases in certain forms of IVV, point to the continued urgency of violence prevention efforts for all U.S. youths and especially those who are disproportionately affected by IVV. |
Prescription opioid misuse and use of alcohol and other substances among high school students - Youth Risk Behavior Survey, United States, 2019
Jones CM , Clayton HB , Deputy NP , Roehler DR , Ko JY , Esser MB , Brookmeyer KA , Hertz MF . MMWR Suppl 2020 69 (1) 38-46 Adolescence is an important period of risk for substance use initiation and substance use-related adverse outcomes. To examine youth substance use trends and patterns, CDC analyzed data from the 2009-2019 Youth Risk Behavior Survey. This report presents estimated prevalence of current (i.e., previous 30-days) marijuana use, prescription opioid misuse, alcohol use, and binge drinking and lifetime prevalence of marijuana, synthetic marijuana, cocaine, methamphetamine, heroin, injection drug use, and prescription opioid misuse among U.S. high school students. Logistic regression and Joinpoint analyses were used to assess 2009-2019 trends. Prevalence of current and lifetime substance use by demographics, frequency of use, and prevalence of co-occurrence of selected substances among students reporting current prescription opioid misuse are estimated using 2019 data. Multivariable logistic regression analysis was used to determine demographic and substance use correlates of current prescription opioid misuse. Current alcohol, lifetime cocaine, methamphetamine, heroin, and injection drug use decreased during 2009-2019. Lifetime use of synthetic marijuana (also called synthetic cannabinoids) decreased during 2015-2019. Lifetime marijuana use increased during 2009-2013 and then decreased during 2013-2019. In 2019, 29.2% reported current alcohol use, 21.7% current marijuana use, 13.7% current binge drinking, and 7.2% current prescription opioid misuse. Substance use varied by sex, race/ethnicity, grade, and sexual minority status (lesbian, gay, or bisexual). Use of other substances, particularly current use of alcohol (59.4%) and marijuana (43.5%), was common among students currently misusing prescription opioids. Findings highlight opportunities for expanding evidence-based prevention policies, programs, and practices that aim to reduce risk factors and strengthen protective factors related to youth substance use, in conjunction with ongoing initiatives for combating the opioid crisis. |
Age-specific probability of 4 major health outcomes in children with spina bifida
Gilbertson KE , Liu T , Wiener JS , Walker WO Jr , Smith K , Castillo J , Castillo H , Wilson P , Peterson P , Clayton GH , Valdez R . J Dev Behav Pediatr 2023 44 (9) e633-e641 OBJECTIVE: This study aimed to estimate the age-specific probability of 4 health outcomes in a large registry of individuals with spina bifida (SB). METHODS: The association between age and 4 health outcomes was examined in individuals with myelomeningocele (MMC, n = 5627) and non-myelomeningocele (NMMC, n = 1442) from the National Spina Bifida Patient Registry. Sixteen age categories were created, 1 for each year between the ages of 5 and 19 years and 1 for those aged 20 years or older. Generalized linear models were used to calculate the adjusted probability and 95% prediction intervals of each outcome for each age category, adjusting for sex and race/ethnicity. RESULTS: For the MMC and NMMC groups, the adjusted coefficients for the correlation between age and the probability of each outcome were -0.933 and -0.657 for bladder incontinence, -0.922 and -0.773 for bowel incontinence, 0.942 and 0.382 for skin breakdown, and 0.809 and 0.619 for lack of ambulation, respectively. CONCLUSION: In individuals with SB, age is inversely associated with the probability of bladder and bowel incontinence and directly associated with the probability of skin breakdown and lack of ambulation. The estimated age-specific probabilities of each outcome can help SB clinicians estimate the expected proportion of patients with the outcome at specific ages and explain the probability of the occurrence of these outcomes to patients and their families. |
Violent victimization during childhood in the United States: Associations with revictimization and health
Basile KC , Chen J , Smith SG , Clayton HB , Simon TR , Mercy JA . Violence Vict 2023 38 (3) 375-395 Childhood violence victimization is a serious adverse childhood experience with lasting health impacts. This study examined the prevalence and characteristics of five forms of childhood violence victimization and their association with revictimization and negative health conditions among adults. Data are from the 2010-2012 National Intimate Partner and Sexual Violence Survey. Age at first victimization and perpetrator sex were assessed; adjusted odds ratios assessed associations with revictimization and health. Ages 14-17 were the most common age at first victimization for most violence types; almost half of male (46.7%) and a quarter of female (27.0%) rape victims reported first victimization before age 10. Most victimization was associated with revictimization and negative health, controlling for adult victimization. Primary prevention of childhood violence may reduce later health risks. |
Bullying victimization and associations with substance use among US middle school students: 2019 Youth Risk Behavior Survey
Barbero C , Vagi KJ , Clayton H , Holland K , Hertz M , Krause KH , Brittingham R , Bunge S , Saka SM , Marchessault N , Hynes N , Green D , Spell L , Monteiro K , Murray K , Reilly-Chammat R , Tignor L , Mercado MC . J Sch Health 2023 93 (12) 1111-1118 BACKGROUND: Research shows associations between bullying victimization and substance use for teens. However, more research about this relationship for younger adolescents and across race/ethnicity is needed. METHODS: Prevalence and pooled logistic regression analyses of 2019 Middle School Youth Risk Behavior Survey data from 13 states (N = 74,059 students) examined associations between self-reported bulling victimization (at school, electronically, and both) and having ever tried cigarette smoking, alcohol, or marijuana; used an electronic vapor product; or misused prescription pain medicine. Regression analyses were adjusted by age and sex/race/ethnicity. RESULTS: All 3 measures of bullying victimization were significantly associated (p < .05) with the 5 substance use behaviors examined (adjusted prevalence ratios ranged from 1.29 to 2.32). These associations held across sexes. Significant associations were found within all 7 race/ethnicity categories, with the most associations reported for the non-Hispanic (NH) white, NH black or African American, Hispanic/Latino, and NH Asian groups. CONCLUSION: The association between bullying and substance use by middle school is a highly relevant issue to consider as students return to classrooms. |
Key insights on multisector community partnerships from real-world efforts to address social determinants of health
Glasgow L , Clayton M , Honeycutt A , Bayer EM , Plescia M , Holtgrave PL , Hacker K . Eval Program Plann 2023 99 102298 PURPOSE: To better understand and inform how multisector community partnerships (MCPs) perform meaningful work to prevent chronic disease and advance health equity by addressing social determinants of health (SDOH). METHODS: We conducted a rapid retrospective evaluation of SDOH initiatives implemented within the past three years by 42 established MCPs across the United States. The mixed methods evaluation included document review and coding of available outcomes data, virtual discussions, and Prevention Impacts Simulation Model (PRISM) analysis. RESULTS: All 42 MCPs built community capacity for addressing SDOH through new or strengthened data systems, leveraged resources, or engaged residents, for example. Most MCPs (N = 38, 90%) reported contributions to community changes that promote healthy living. More than half of the MCPs (N = 22) reported health outcomes data for their SDOH initiatives, including improved health behaviors and clinical outcomes. Based on reach data provided by 27 MCPs, PRISM analysis results suggest that sustained initiatives could save over $633 million in productivity and medical costs cumulatively through 20 years. CONCLUSIONS: With sufficient technical assistance and funding resources, MCPs are a key component of the public health strategy to address SDOH. |
Estimating burden of syphilis among men who have sex with men - Authors' reply
Chico RM , Tsuboi M , Evans J , Davies EP , Rowley J , Korenromp EL , Clayton T , Mabey D , Taylor MM . Lancet Glob Health 2021 9 (12) e1649 Can a change in venues sampled in syphilis serosurveys influence prevalence estimates among men who have sex with men (MSM), and has this contributed to spurious trends of decline in the past decade? In this issue of The Lancet Global Health, Ting-Ting Jiang and colleagues in their Correspondence pose this question and note evidence from China that HIV prevalence evaluated among MSM at public bathhouses and saunas is consistently higher than among MSM recruited through internet sites.1 This difference in testing venues could extend to syphilis, although such a difference was not apparent in our recent global systematic review and meta-analysis of syphilis prevalence among MSM published in The Lancet Global Health.2 In our study, the pooled prevalence estimate of syphilis among studies that recruited MSM at venues including bathhouses and saunas, clubs, and one-off public events was 6·1% (95% CI 3·7–9·1; 13 229 MSM; 29 data points). When taking into account MSM studies that used a variety of convenience sampling methods, including internet advertising, the pooled prevalence estimate was 8·7% (95% CI 7·6–9·9%; 109 065 MSM; 64 data points). Neither of these subgroup estimates were meaningfully different from our overall pooled estimate of 7·5% (95% CI 7·0–8·0; 606 232 MSM; 345 data points). However, a prevalence data compilation and trend estimation of syphilis in Yunnan province, China did find prevalence among MSM (or female sex workers) to be systematically lower in routine annual surveillance surveys and higher in research studies.3 The venues involved might have contributed to this difference, although neither dataset (nor their weighted sum) showed a statistically significant upward or downward prevalence trend over 2010–17; these findings do highlight the importance of inferring time trends only within series of methodologically comparable samples. |
Associations of adverse childhood experiences with pregnancy and infant health
Swedo EA , D'Angelo DV , Fasula AM , Clayton HB , Ports KA . Am J Prev Med 2023 64 (4) 512-524 INTRODUCTION: Adverse childhood experiences are associated with a host of negative outcomes; however, few have studied cumulative adverse childhood experiences in the context of pregnancy and infant health. This study examines state-level prevalence of adverse childhood experiences and associations with pregnancy- and infant health‒related indicators. METHODS: The study used 2016-2018 Pregnancy Risk Assessment Monitoring System population-based data from 5 states. Analyses were conducted for individual states and grouped states using similar adverse childhood experience items. Thirteen adverse childhood experience measures were included across 3 domains: abuse, neglect, and household challenges. Adverse childhood experience scores were calculated for the number of adverse childhood experiences experienced (0, 1, 2, ≥3) on the basis of available state measures. Fourteen pregnancy- and infant health‒related indicators were examined, including unwanted pregnancy, adequate prenatal care, experiences during pregnancy (e.g., smoking, abuse, depression), gestational diabetes, hypertensive disorders of pregnancy, birth outcomes (e.g., preterm birth), and breastfeeding. Adjusting for demographics, parity, health insurance status, and educational attainment, prevalence ratios and 95% CIs were calculated to examine the associations between pregnancy- and infant health‒related indicators and adverse childhood experience scores. RESULTS: Over 50% of respondents reported at least 1 adverse childhood experience and 13%-31% reported ≥3 adverse childhood experiences, depending on the state. Significant associations were identified in all adjusted models between adverse childhood experiences and unwanted pregnancy, smoking, physical abuse, and depression during pregnancy. CONCLUSIONS: Adverse childhood experiences are associated with risk factors that impact pregnancy and infant health. Preventing and mitigating adverse childhood experiences is an important strategy to improve pregnancy- and infant health‒related indicators. |
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. |
First cases of SARS-CoV-2 infection and secondary transmission in Kisumu, Kenya
Tippett Barr Beth A , Herman-Roloff Amy , Mburu Margaret , Murnane Pamela M , Sang Norton , Bukusi Elizabeth , Oele Elizabeth , Odhiambo Albert , Lewis-Kulzer Jayne , Onyango Clayton O , Hunsperger Elizabeth , Odhiambo Francesca , Joseph Rachel H , Munyua Peninah , Othieno Kephas , Mulwa Edwin , Akelo Victor , Muok Erick , Bulterys Marc , Nzioka Charles , Cohen Craig R . PLoS Glob Public Health 2022 2 (9) e0000951 We investigated the first 152 laboratory-confirmed SARS-CoV-2 cases (125 primary and 27 secondary) and their 248 close contacts in Kisumu County, Kenya. Conducted June 10–October 8, 2020, this study included interviews and sample collection at enrolment and 14–21 days later. Median age was 35 years (IQR 28–44); 69.0% reported COVID-19 related symptoms, most commonly cough (60.0%), headache (55.2%), fever (53.3%) and loss of taste or smell (43.8%). One in five were hospitalized, 34.4% >25 years of age had at least one comorbidity, and all deaths had comorbidities. Adults ≥25 years with a comorbidity were 3.15 (95% CI 1.37–7.26) times more likely to have been hospitalized or died than participants without a comorbidity. Infectious comorbidities included HIV, tuberculosis, and malaria, but no current cases of influenza, respiratory syncytial virus, dengue fever, leptospirosis or chikungunya were identified. Thirteen (10.4%) of the 125 primary infections transmitted COVID-19 to 27 close contacts, 158 (63.7%) of whom resided or worked within the same household. Thirty-one percent (4 of 13) of those who transmitted COVID-19 to secondary cases were health care workers; no known secondary transmissions occurred between health care workers. This rapid assessment early in the course of the COVID-19 pandemic identified some context-specific characteristics which conflicted with the national line-listing of cases, and which have been substantiated in the year since. These included over two-thirds of cases reporting the development of symptoms during the two weeks after diagnosis, compared to the 7% of cases reported nationally; over half of cases reporting headaches, and nearly half of all cases reporting loss of taste and smell, none of which were reported at the time by the World Health Organization to be common symptoms. This study highlights the importance of rapid in-depth assessments of outbreaks in understanding the local epidemiology and response measures required. |
Adverse Childhood Experiences During the COVID-19 Pandemic and Associations with Poor Mental Health and Suicidal Behaviors Among High School Students - Adolescent Behaviors and Experiences Survey, United States, January-June 2021.
Anderson KN , Swedo EA , Trinh E , Ray CM , Krause KH , Verlenden JV , Clayton HB , Villaveces A , Massetti GM , HolditchNiolon P . MMWR Morb Mortal Wkly Rep 2022 71 (41) 1301-1305 Social and educational disruptions during the COVID-19 pandemic have exacerbated concerns about adolescents' mental health and suicidal behavior. Data from the 2021 Adolescent Behaviors and Experiences Survey (ABES) indicate that 37.1% of U.S. high school students reported poor mental health during the COVID-19 pandemic, with 19.9% considering and 9.0% attempting suicide in the preceding year (1). Adverse childhood experiences (ACEs)* are associated with poor mental health and suicidal behaviors (2,3), and high prevalence of some ACEs have been documented during the pandemic (4). ACEs are preventable, potentially traumatic events that occur in childhood (ages 0-17 years) such as neglect, experiencing or witnessing violence, or having a family member attempt or die by suicide. Also included are aspects of a child's environment that can undermine their sense of safety, stability, and bonding. Associations between ACEs occurring during the pandemic and mental health or suicidal behaviors among U.S. high school students were examined using ABES data. Experience of one to two ACEs was associated with poorer mental health and increased suicidal behaviors, and these deleterious outcomes increased with additional ACE exposure. After adjusting for demographic characteristics, adolescents who reported four or more ACEs during the pandemic had a prevalence of poor current mental health four times as high as, and a prevalence of past-year suicide attempts 25 times as high as, those without ACEs during the pandemic. Experience of specific ACE types (e.g., emotional abuse) was associated with higher prevalences of poor mental health and suicidal behaviors. Prevention and intervention strategies (5), including early identification and trauma-informed mental health service and support provision, for ACEs and their acute and long-term impacts could help address the U.S. child and adolescent mental health and suicide crisis.(). |
Gun carrying among youths, by demographic characteristics, associated violence experiences, and risk behaviors - United States, 2017-2019
Simon TR , Clayton HB , Dahlberg LL , David-Ferdon C , Kilmer G , Barbero C . MMWR Morb Mortal Wkly Rep 2022 71 (30) 953-957 Suicide and homicide are the second and third leading causes of death, respectively, among youths aged 14-17 years (1); nearly one half (46%) of youth suicides and most (93%) youth homicides result from firearm injuries (1). Understanding youth gun carrying and associated outcomes can guide prevention initiatives (2). This study used the updated measure of gun carrying in the 2017 and 2019 administrations of CDC's Youth Risk Behavior Survey* (YRBS) to describe the national prevalence of gun carrying for reasons other than hunting or sport among high school students aged <18 years and to examine the associations between gun carrying and experiencing violence, suicidal ideation or attempts, or substance use. Gun carrying during the previous 12 months was reported by one in 15 males and one in 50 females. Gun carrying was significantly more likely among youths with violence-related experiences (adjusted prevalence ratio [aPR] range = 1.5-10.1), suicidal ideation or attempts (aPR range = 1.8-3.5), or substance use (aPR range = 4.2-5.6). These results underscore the importance of comprehensive approaches to preventing youth violence and suicide, including strategies that focus on preventing youth substance use and gun carrying (3). |
Building infrastructure for surveillance of adverse and positive childhood experiences: Integrated, multimethod approaches to generate data for prevention action
Anderson KN , Swedo EA , Clayton HB , Niolon PH , Shelby D , McDavidHarrison K . Am J Prev Med 2022 62 S31-s39 Adverse and positive childhood experiences have a profound impact on lifespan health and well-being. However, their incorporation into ongoing population-based surveillance systems has been limited. This paper outlines critical steps in building a comprehensive approach to adverse and positive childhood experiences surveillance, provides examples from the Preventing Adverse Childhood Experiences: Data to Action cooperative agreement, and describes improvements needed to optimize surveillance data for action. Components of a comprehensive approach to adverse and positive childhood experiences surveillance include revisiting definitions and measurement, including generating and using uniform definitions for adverse and positive childhood experiences across data collection efforts; conducting youth-based surveillance of adverse and positive childhood experiences; using innovative methods to gather and analyze near real-time data; leveraging available data, including from administrative sources; and integrating data on community- and societal-level risk and protective factors for adverse childhood experiences, including social and health inequities such as racism and poverty, as well as policies and conditions that create healthy environments for children and families. Comprehensive surveillance data on adverse and positive childhood experiences can inform data-driven prevention and intervention efforts, including focusing prevention programming and services to populations in greatest need. Data can be used to evaluate progress in reducing the occurrence of adverse childhood experiences and bolstering the occurrence of positive childhood experiences. Through expansion and improvement in adverse and positive childhood experiences surveillance-including at federal, state, territorial, tribal, and local levels-data-driven action can reduce children's exposure to violence and other adversities and improve lifelong health and well-being. |
Social vulnerability and rurality associated with higher SARS-CoV-2 infection-induced seroprevalence: a nationwide blood donor study, United States, July 2020 - June 2021.
Li Z , Lewis B , Berney K , Hallisey E , Williams AM , Whiteman A , Rivera-González LO , Clarke KEN , Clayton H , Tincher T , Opsomer JD , Busch MP , Gundlapalli A , Jones JM . Clin Infect Dis 2022 75 (1) e133-e143 BACKGROUND: Most studies on health disparities during COVID-19 pandemic focused on reported cases and deaths, which are influenced by testing availability and access to care. This study aimed to examine SARS-CoV-2 antibody seroprevalence in the U.S. and its associations with race/ethnicity, rurality, and social vulnerability over time. METHODS: This repeated cross-sectional study used data from blood donations in 50 states and Washington, D.C. from July 2020 through June 2021. Donor ZIP codes were matched to counties and linked with Social Vulnerability Index (SVI) and urban-rural classification. SARS-CoV-2 antibody seroprevalences induced by infection and infection-vaccination combined were estimated. Association of infection-induced seropositivity with demographics, rurality, SVI, and its four themes were quantified using multivariate regression models. FINDINGS: Weighted seroprevalence differed significantly by race/ethnicity and rurality, and increased with increasing social vulnerability. During the study period, infection-induced seroprevalence increased from 1.6% to 27.2% and 3.7% to 20.0% in rural and urban counties, respectively, while rural counties had lower combined infection- and vaccination-induced seroprevalence (80.0% vs. 88.1%) in June 2021. Infection-induced seropositivity was associated with being Hispanic, non-Hispanic Black, and living in rural or higher socially vulnerable counties, after adjusting for demographic and geographic covariates. CONCLUSION: The findings demonstrated increasing SARS-CoV-2 seroprevalence in the U.S. across all geographic, demographic, and social sectors. The study illustrated disparities by race-ethnicity, rurality, and social vulnerability. The findings identified areas for targeted vaccination strategies and can inform efforts to reduce inequities and prepare for future outbreaks. |
Racial and Ethnic Disparities in COVID-19 Vaccination Coverage: The Contribution of Socioeconomic and Demographic Factors.
Williams AM , Clayton HB , Singleton JA . Am J Prev Med 2021 62 (4) 473-482 INTRODUCTION: Health disparities among racial and ethnic and socioeconomic groups are pervasive, and the COVID-19 pandemic has not been an exception. This study explores the key demographic and socioeconomic factors related to racial and ethnic disparities in COVID-19 vaccination coverage. METHODS: Using recent (January 2021-March 2021) data on adults from the U.S. Census Bureau Household Pulse Survey, a regression-based decomposition method was used to estimate how much of the observed racial and ethnic disparities in vaccination coverage could be explained by particular socioeconomic and demographic factors (i.e., age, number of children and adults in household). RESULTS: Demographics, socioeconomic factors, and experiencing economic hardship during the pandemic each explained a statistically significant portion of vaccination coverage disparities between non-Hispanic White and racial/ethnic minority individuals. The largest disparity was observed among people who identified as Hispanic or Latino, whose vaccination coverage was 8.0 (95% CI=7.1, 8.9) percentage points lower than that of their non-Hispanic White counterparts. Socioeconomic factors explained 4.8 (95% CI=4.3, 5.2) percentage points of this disparity, and economic hardship explained an additional 1.4 (95% CI=1.2, 1.6) percentage points. CONCLUSIONS: This paper identified the key factors related to racial and ethnic disparities in adult vaccination coverage. The variables that explained the largest portions of the disparities were age, education, employment, and income. The study findings can help to inform efforts to increase equitable vaccine access and engage various segments of the population to prevent the further exacerbation of COVID-19 health disparities. |
Food Insecurity and Its Association With Alcohol and Other Substance Use Among High School Students in the United States
Turner VE , Demissie Z , Sliwa SA , Clayton HB . J Sch Health 2021 92 (2) 177-184 BACKGROUND: Studies show that food insecurity is associated with adverse health behaviors for children and adults. However, published data among adolescents are limited. The objective of this study was to examine the association between food insecurity and substance use behaviors among US high school students. METHODS: Data from the 2017 Youth Risk Behavior Survey in 10 states were combined to examine the association between household food insecurity and adolescent use of alcohol, marijuana, prescription opioid misuse, and illicit drugs using logistic regression. RESULTS: Among surveyed respondents, 12.3% of high school students reported experiencing food insecurity. In unadjusted analyses, the prevalence of substance use was higher among students with food insecurity compared to food secure students: current binge drinking (16.2% vs 11.5%), current marijuana use (24.0% vs 16.2%), lifetime prescription opioid misuse (21.3% vs 12.6%), and lifetime use of illicit drugs (12.3% vs 5.0%) (all p < .05). In adjusted models, food insecurity was associated with lifetime prescription opioid misuse and lifetime use of illicit drugs (aPR 1.38 and 1.70, respectively). CONCLUSION: Students with food insecurity are a potential group at a higher rise of substance misuse and may benefit from prevention programs designed to address their needs. |
Prevalence of syphilis among men who have sex with men: a global systematic review and meta-analysis from 2000-20
Tsuboi M , Evans J , Davies EP , Rowley J , Korenromp EL , Clayton T , Taylor MM , Mabey D , Chico RM . Lancet Glob Health 2021 9 (8) e1110-e1118 BACKGROUND: The WHO Global Health Sector Strategy aims to reduce worldwide syphilis incidence by 90% between 2018 and 2030. If this goal is to be achieved, interventions that target high-burden groups, including men who have sex with men (MSM), will be required. However, there are no global prevalence estimates of syphilis among MSM to serve as a baseline for monitoring or modelling disease burden. We aimed to assess the global prevalence of syphilis among MSM using the available literature. METHODS: In this global systematic review and meta-analysis, we searched MEDLINE, Embase, LILACS, and AIM databases, and Integrated Bio-Behavioral Surveillance (IBBS) reports between April 23, 2019, and Feb 1, 2020, to identify studies done between Jan 1, 2000, and Feb 1, 2020, with syphilis point prevalence data measured by biological assay among MSM (defined as people who were assigned as male at birth and had oral or anal sex with at least one other man in their lifetime). Studies were excluded if participants were exclusively HIV-infected MSM, injection-drug users, only seeking care for sexually transmitted infections (STIs) or genital symptoms, or routine STI clinic attendees. Data were extracted onto standardised forms and cross-checked for accuracy and validity. We used random-effects models to generate pooled prevalence estimates across the eight regions of the Sustainable Development Goals. We calculated risk of study bias based on the Appraisal tool for Cross-Sectional Studies, and stratified results based on low versus high risk of bias. This systematic review and meta-analysis was registered with PROSPERO, CRD42019144594. FINDINGS: We reviewed 4339 records, 228 IBBS reports, and ten articles from other sources. Of these, 1301 duplicate records were excluded, 2467 records were excluded after title and abstract screening, and 534 articles were excluded after full-text analysis. We identified 345 prevalence data points from 275 studies across 77 countries, with a total of 606 232 participants. Global pooled prevalence from 2000-20 was 7·5% (95% CI 7·0-8·0%), ranging from 1·9% (1·0-3·1%) in Australia and New Zealand to 10·6% (8·5-12·9%) in Latin America and the Caribbean. INTERPRETATION: Unacceptably high syphilis prevalence among MSM warrants urgent action. FUNDING: Wellcome Trust. |
Disparities in COVID-19 Vaccination Coverage Between Urban and Rural Counties - United States, December 14, 2020-April 10, 2021.
Murthy BP , Sterrett N , Weller D , Zell E , Reynolds L , Toblin RL , Murthy N , Kriss J , Rose C , Cadwell B , Wang A , Ritchey MD , Gibbs-Scharf L , Qualters JR , Shaw L , Brookmeyer KA , Clayton H , Eke P , Adams L , Zajac J , Patel A , Fox K , Williams C , Stokley S , Flores S , Barbour KE , Harris LQ . MMWR Morb Mortal Wkly Rep 2021 70 (20) 759-764 Approximately 60 million persons in the United States live in rural counties, representing almost one fifth (19.3%) of the population.* In September 2020, COVID-19 incidence (cases per 100,000 population) in rural counties surpassed that in urban counties (1). Rural communities often have a higher proportion of residents who lack health insurance, live with comorbidities or disabilities, are aged ≥65 years, and have limited access to health care facilities with intensive care capabilities, which places these residents at increased risk for COVID-19-associated morbidity and mortality (2,3). To better understand COVID-19 vaccination disparities across the urban-rural continuum, CDC analyzed county-level vaccine administration data among adults aged ≥18 years who received their first dose of either the Pfizer-BioNTech or Moderna COVID-19 vaccine, or a single dose of the Janssen COVID-19 vaccine (Johnson & Johnson) during December 14, 2020-April 10, 2021 in 50 U.S. jurisdictions (49 states and the District of Columbia [DC]). Adult COVID-19 vaccination coverage was lower in rural counties (38.9%) than in urban counties (45.7%) overall and among adults aged 18-64 years (29.1% rural, 37.7% urban), those aged ≥65 years (67.6% rural, 76.1% urban), women (41.7% rural, 48.4% urban), and men (35.3% rural, 41.9% urban). Vaccination coverage varied among jurisdictions: 36 jurisdictions had higher coverage in urban counties, five had higher coverage in rural counties, and five had similar coverage (i.e., within 1%) in urban and rural counties; in four jurisdictions with no rural counties, the urban-rural comparison could not be assessed. A larger proportion of persons in the most rural counties (14.6%) traveled for vaccination to nonadjacent counties (i.e., farther from their county of residence) compared with persons in the most urban counties (10.3%). As availability of COVID-19 vaccines expands, public health practitioners should continue collaborating with health care providers, pharmacies, employers, faith leaders, and other community partners to identify and address barriers to COVID-19 vaccination in rural areas (2). |
Widespread SARS-CoV-2 Transmission Among Attendees at a Large Motorcycle Rally and their Contacts, 30 US Jurisdictions, August-September, 2020.
Carter RJ , Rose D , Sabo R , Clayton J , Steinberg J , Anderson M . Clin Infect Dis 2021 73 S106-S109 The 2020 Sturgis Motorcycle rally resulted in widespread transmission of SARS-CoV-2 across the United States. At least 649 COVID-19 cases were identified, including secondary and tertiary spread to close contacts. To limit transmission, persons attending events should wear masks and practice physical distancing. Persons with a known exposure should quarantine and obtain COVID-19 testing. |
Initiation of nonmedical use of prescription opioids among high school students
Deputy NP , Lowry R , Clayton HB , Demissie Z , Bohm MK , Conklin S . Subst Abus 2021 42 (4) 1-6 Nonmedical use of prescription opioids (NUPO) is associated with heroin use and other adverse outcomes among adolescents. To inform the timing of substance use prevention activities and which substances to target, we examined age at NUPO initiation, associations between substance use initiation and current (past 30-day) NUPO, and order of NUPO initiation relative to other substances. Methods: Data from 2,834 students aged 15 or older participating in the 2017 Virginia Youth Survey, the first Youth Risk Behavior Surveillance System survey to assess age at NUPO initiation and current NUPO, were analyzed in 2019. Students reported current NUPO and ages at initiation for cigarettes, alcohol, marijuana, and NUPO (categorized as 12 or younger, 13 or 14, 15 or older, or never). Associations between age at substance use initiation and current NUPO were examined using adjusted prevalence ratios (aPRs) and 95% confidence intervals (CIs). Results: Overall, 12% of students reported lifetime NUPO, with 2.4%, 4.0%, and 5.6% initiating at 12 or younger, 13 or 14, and 15 or older, respectively; 5.3% reported current NUPO. Initiating cigarettes, alcohol, and marijuana at each age category (compared with never) was associated with an increased prevalence of current NUPO after adjusting for demographics and initiation of other substances. Among students initiating NUPO, initiating NUPO at 12 or younger (compared with 15 or older) was associated with an increased prevalence of current NUPO after adjusting for demographics (aPR = 1.54, 95% CI: 1.10-2.16), but not after further adjustment for initiation of other substances (aPR = 1.38, 95% CI = 0.97-1.97). Among students initiating NUPO, 45.4% initiated NUPO before or during the same age as other substances. Conclusions: More than 6% of students initiated NUPO at 14 or younger. Younger substance use initiation was associated with current NUPO, suggesting that some students may benefit from prevention activities during early adolescence that address multiple substances. |
Cumulative protective factors are associated with decreased risk for prescription opioid misuse among high school students
Timpe Z , Clayton HB , Andrzejewski J , Phillips C , Conklin S , Bohm MK . J Epidemiol Community Health 2021 75 (10) 987-993 BACKGROUND: Multiple protective factors at the individual and environmental levels have been associated with prescription opioid misuse (POM) among adolescents. The literature may benefit by extending this research to consider the association between cumulative protective factors and current (ie, within the past 30 days) POM. METHODS: The 2017 Virginia Youth Survey (part of the Youth Risk Behaviour Surveillance System) (N=3697) was used to investigate recent POM and the presence of individual and cumulative protective factors among high school students. Youth were asked to indicate whether they had engaged POM within the past 30 days. A set of protective factors representing youths' internal assets (eg, aspirational plans for education) and external resources (eg, family meals, safe school environment) were investigated as predictors of current POM, followed by testing of a cumulative protective factor score. Logistic regression models estimated ORs and 95% CIs. RESULTS: When including demographics and risk factors in the model, none of the individual protective factors were significantly associated with current POM. Alternatively, the cumulative protective factor score was significantly associated with a decrease in the odds of current POM. CONCLUSIONS: The cumulative protective factor score was significantly associated with a decrease in the odds of current POM among high school students in Virginia. Programmes designed to provide multiple forms of support may be effective strategies for preventing current POM. |
Current Prescription Opioid Misuse and Suicide Risk Behaviors Among High School Students
Wilkins NJ , Clayton H , Jones CM , Brown M . Pediatrics 2021 147 (4) BACKGROUND AND OBJECTIVES: In previous studies, researchers have reported that youth with a lifetime history of prescription opioid misuse (POM) are at an increased risk for suicidal ideation, planning, and attempts. In this study, we investigate whether the association between youth POM and suicide outcomes differs by recency of POM (ie, none, past, or current misuse). METHODS: In this report, we use data from the 2019 Youth Risk Behavior Survey to examine associations between recency of POM (current POM, past POM, and no POM) and suicide risk behaviors among US high school students. RESULTS: After controlling for demographics, alcohol, and other drug use, both current POM and past POM were significantly associated with all suicide risk behaviors compared with no POM. Students who reported current POM had the highest adjusted prevalence ratios (aPRs) for suicidal ideation (aPR: 2.30; 95% confidence interval [CI] 1.97-2.69), planning (aPR: 2.33; 95% CI 1.99-2.79), attempts (aPR: 3.21; 95% CI 2.56-4.02), and feeling sad or hopeless (aPR: 1.59; 95% CI 1.37-1.84). Students who reported current POM also were significantly more likely than youth who reported past POM to report that they had seriously considered attempting suicide, made a suicide plan, and attempted suicide. CONCLUSIONS: Although POM, particularly current POM, is associated with increases in the risk for suicide-related behaviors and experiences of youth, comprehensive prevention approaches that address the intersections between suicide and POM provide a promising path forward for addressing these public health challenges among youth. |
Vital Signs: Prevalence of multiple forms of violence and increased health risk behaviors and conditions among youths - United States, 2019
David-Ferdon C , Clayton HB , Dahlberg LL , Simon TR , Holland KM , Brener N , Matjasko JL , D'Inverno AS , Robin L , Gervin D . MMWR Morb Mortal Wkly Rep 2021 70 (5) 167-173 INTRODUCTION: Experiencing violence, especially multiple types of violence, can have a negative impact on youths' development. These experiences increase the risk for future violence and other health problems associated with the leading causes of morbidity and mortality among adolescents and adults. METHODS: Data from the 2019 national Youth Risk Behavior Survey were used to determine the prevalence of high school students' self-reported experiences with physical fighting, being threatened with a weapon, physical dating violence, sexual violence, and bullying. Logistic regression models adjusting for sex, grade, and race/ethnicity were used to test the strength of associations between experiencing multiple forms of violence and 16 self-reported health risk behaviors and conditions. RESULTS: Approximately one half of students (44.3%) experienced at least one type of violence; more than one in seven (15.6%) experienced two or more types during the preceding 12 months. Experiencing multiple types of violence was significantly more prevalent among females than among males and among students identifying as gay, lesbian, or bisexual or not sure of their sexual identity than among heterosexual students. Experiencing violence was significantly associated with higher prevalence of all examined health risks and conditions. Relative to youths with no violence experiences, adjusted health risk and condition prevalence estimates were up to seven times higher among those experiencing two types of violence and up to 21 times higher among those experiencing three or more types of violence. CONCLUSIONS AND IMPLICATIONS FOR PUBLIC HEALTH PRACTICE: Many youths experience multiple types of violence, with potentially lifelong health impacts. Violence is preventable using proven approaches that address individual, family, and environmental risks. Prioritizing violence prevention is strategic to promoting adolescent and adult health. |

PLoS One 2020 15 (10) e0240309 INTRODUCTION: Etiology studies of severe acute respiratory infections (SARI) in adults are limited. We studied potential etiologies of SARI among adults in six countries using multi-pathogen diagnostics. METHODS: We enrolled both adults with SARI (acute respiratory illness onset with fever and cough requiring hospitalization) and asymptomatic adults (adults hospitalized with non-infectious illnesses, non-household members accompanying SARI patients, adults enrolled from outpatient departments, and community members) in each country. Demographics, clinical data, and nasopharyngeal and oropharyngeal specimens were collected from both SARI patients and asymptomatic adults. Specimens were tested for presence of 29 pathogens utilizing the Taqman® Array Card platform. We applied a non-parametric Bayesian regression extension of a partially latent class model approach to estimate proportions of SARI caused by specific pathogens. RESULTS: We enrolled 2,388 SARI patients and 1,135 asymptomatic adults from October 2013 through October 2015. We detected ≥1 pathogen in 76% of SARI patients and 67% of asymptomatic adults. Haemophilus influenzae and Streptococcus pneumoniae were most commonly detected (≥23% of SARI patients and asymptomatic adults). Through modeling, etiology was attributed to a pathogen in most SARI patients (range among countries: 57.3-93.2%); pathogens commonly attributed to SARI etiology included influenza A (14.4-54.4%), influenza B (1.9-19.1%), rhino/enterovirus (1.8-42.6%), and RSV (3.6-14.6%). CONCLUSIONS: Use of multi-pathogen diagnostics and modeling enabled attribution of etiology in most adult SARI patients, despite frequent detection of multiple pathogens in the upper respiratory tract. Seasonal flu vaccination and development of RSV vaccine would likely reduce the burden of SARI in these populations. |

Adolescent marijuana use and related risk behaviors, national findings from 2015 to 2017
Schauer GL , Clayton HB , Njai R , Grant AM . Am J Prev Med 2020 59 (5) 714-724 INTRODUCTION: As policies legalizing nonmedical marijuana have increased in states, understanding the implications of marijuana use among adolescents is increasingly important. This study uses nationally representative data to assess behavioral risk factors among students with different patterns of marijuana use. METHODS: Data from the 2015 and 2017 Youth Risk Behavior Surveys, cross-sectional surveys conducted among a nationally representative sample of students in Grades 9-12 (n=30,389), were used to examine the association between self-reported current marijuana use status and self-report of 30 risk behaviors across 3 domains: substance use, injury/violence, and sexual health. Among current marijuana users, authors assessed differences between established (≥100 lifetime uses) and nonestablished (<100 uses) users. Multivariable models were used to calculate adjusted prevalence ratios. Data were analyzed in 2019. RESULTS: Current marijuana users (regardless of use pattern) had a significantly greater likelihood of engaging in 27 of the 30 behaviors assessed across the 3 domains than the noncurrent users. Those with established use patterns (versus nonestablished) had a greater risk of lifetime use of most other substances (licit and illicit, including tobacco, alcohol, heroin, misuse of opioids), some injury/violence behaviors (including driving while using marijuana and suicide ideation and attempt), and sexual risk behaviors. CONCLUSIONS: Both established and nonestablished patterns of adolescent marijuana use are associated with a number of other risky behaviors. In addition to interventions focused on preventing youth initiation of marijuana, clinicians and public health professionals should consider interventions to help adolescents who have nonestablished use patterns to avoid continued, established use. |
Nonmedical use of prescription opioids, heroin use, injection drug use, and overdose mortality in U.S. adolescents
Bohm MK , Clayton HB . J Stud Alcohol Drugs 2020 81 (4) 484-488 OBJECTIVE: We assessed overdose mortality by opioid types involved as well as interrelationships between nonmedical use of prescription opioids (NUPO) and heroin and injection drug use (IDU) among adolescents. METHOD: We examined 2010 and 2016 overdose data by drug type for decedents in the United States ages 15-19 years from the Multiple Cause of Death Files. We also analyzed data from the 2017 National Youth Risk Behavior Survey, a nationally representative survey of high school students. We assessed lifetime NUPO and calculated heroin use and IDU by frequency of lifetime NUPO. Adjusted prevalence ratios (aPRs) were generated, and linear contrast analysis determined dose-response relationships between frequency of lifetime NUPO and the two outcomes. RESULTS: The percentage of deaths involving prescription opioids that also involved illicit opioids such as heroin or fentanyl was 5.5% in 2010 and 25.0% in 2016. We observed a positive dose-response relationship with frequency of lifetime NUPO; aPRs were highest for 20 or more times of NUPO and heroin use (aPR = 49.49, 95% CI [33.39, 73.34]) and IDU (aPR = 44.37, 95% CI [23.16, 84.99]). However, aPRs for heroin and IDU were high even among those reporting just one or two occasions of NUPO (aPRs = 9.25, 95% CI [5.90, 14.49] and 6.63, 95% CI [3.99, 11.02], respectively). CONCLUSIONS: Adolescent prescription opioid overdose deaths now frequently involve illicit opioids. Heroin use and IDU are higher among students reporting even a few instances of NUPO, indicating that students with any NUPO are an important risk group. Clinical, community, and school-based efforts can address NUPO, noting these associations. |
Mass Testing for SARS-CoV-2 in 16 Prisons and Jails - Six Jurisdictions, United States, April-May 2020.
Hagan LM , Williams SP , Spaulding AC , Toblin RL , Figlenski J , Ocampo J , Ross T , Bauer H , Hutchinson J , Lucas KD , Zahn M , Chiang C , Collins T , Burakoff A , Bettridge J , Stringer G , Maul R , Waters K , Dewart C , Clayton J , de Fijter S , Sadacharan R , Garcia L , Lockett N , Short K , Sunder L , Handanagic S . MMWR Morb Mortal Wkly Rep 2020 69 (33) 1139-1143 Preventing coronavirus disease 2019 (COVID-19) in correctional and detention facilities* can be challenging because of population-dense housing, varied access to hygiene facilities and supplies, and limited space for isolation and quarantine (1). Incarcerated and detained populations have a high prevalence of chronic diseases, increasing their risk for severe COVID-19-associated illness and making early detection critical (2,3). Correctional and detention facilities are not closed systems; SARS-CoV-2, the virus that causes COVID-19, can be transmitted to and from the surrounding community through staff member and visitor movements as well as entry, transfer, and release of incarcerated and detained persons (1). To better understand SARS-CoV-2 prevalence in these settings, CDC requested data from 15 jurisdictions describing results of mass testing events among incarcerated and detained persons and cases identified through earlier symptom-based testing. Six jurisdictions reported SARS-CoV-2 prevalence of 0%-86.8% (median = 29.3%) from mass testing events in 16 adult facilities. Before mass testing, 15 of the 16 facilities had identified at least one COVID-19 case among incarcerated or detained persons using symptom-based testing, and mass testing increased the total number of known cases from 642 to 8,239. Case surveillance from symptom-based testing has likely underestimated SARS-CoV-2 prevalence in correctional and detention facilities. Broad-based testing can provide a more accurate assessment of prevalence and generate data to help control transmission (4). |
