Factors Associated with Use of HIV Prevention and Health Care Among Transgender Women - Seven Urban Areas, 2019-2020.

Transgender women* are disproportionately affected by HIV. Among 1,608 transgender women who participated in CDC's National HIV Behavioral Surveillance (NHBS) during 2019-2020, 42% received a positive HIV test result (1). This report provides results from seven U.S. urban areas where the 2019-2020 NHBS questionnaire was administered. Thirty-eight percent of participants reported having previously received a positive test result for HIV. Detrimental socioeconomic factors, including low income (44%), homelessness (39%), and severe food insecurity in the past 12 months (40%), were common and associated with lower receipt of HIV prevention and treatment services. Having a usual health care source or a provider with whom the participant was comfortable discussing gender-related health issues was associated with improved HIV prevention and treatment outcomes, including HIV testing, preexposure prophylaxis (PrEP) use, and viral suppression. These findings illustrate the benefit of gender-affirming approaches used by health care providers (2), and highlight the challenging socioeconomic conditions faced by many transgender women. Ensuring access to gender-affirming health care approaches and addressing the socioeconomic challenges of many transgender women could improve access to and use of HIV prevention and care in this population and will help achieve the goals of the Ending the HIV Epidemic in the United States initiative (3).

Racial, Ethnic, and Gender Disparities in Awareness of Preexposure Prophylaxis Among HIV-Negative Heterosexually Active Adults at Increased Risk for HIV Infection - 23 Urban Areas, United States, 2019.

In 2019, heterosexual sex accounted for 23% of new HIV diagnoses in the United States and six dependent areas (1). Although preexposure prophylaxis (PrEP) can safely reduce the risk for HIV infection among heterosexual persons, this group is underrepresented in PrEP research (2). CDC analyzed National HIV Behavioral Surveillance (NHBS) data to describe PrEP awareness among heterosexually active adults in cities with high HIV prevalence. Overall, although 32.3% of heterosexually active adults who were eligible were aware of PrEP, <1% used PrEP. Racial, ethnic, and gender disparities were identified, with the lowest awareness of PrEP among residents of Puerto Rico (5.8%) and Hispanic or Latino (Hispanic) men (19.5%) and women (17.6%). Previous studies have found that heterosexual adults are interested in taking PrEP when they are aware of it (3); tailoring PrEP messaging, including Spanish-language messaging, to heterosexual adults, might increase PrEP awareness and mitigate disparities in use.

Vital Signs: HIV Infection, Diagnosis, Treatment, and Prevention Among Gay, Bisexual, and Other Men Who Have Sex with Men - United States, 2010-2019.

BACKGROUND: Men who have sex with men (MSM) accounted for two thirds of new HIV infections in the United States in 2019 despite representing approximately 2% of the adult population. METHODS: CDC analyzed surveillance data to determine trends in estimated new HIV infections and to assess measures of undiagnosed infection and HIV prevention and treatment services including HIV testing, preexposure prophylaxis (PrEP) use, antiretroviral therapy (ART) adherence, and viral suppression, as well as HIV-related stigma. RESULTS: The estimated number of new HIV infections among MSM was 25,100 in 2010 and 23,100 in 2019. New infections decreased significantly among White MSM but did not decrease among Black or African American (Black) MSM and Hispanic/Latino MSM. New infections increased among MSM aged 25-34 years. During 2019, approximately 83% of Black MSM and 80% of Hispanic/Latino MSM compared with 90% of White MSM with HIV had received an HIV diagnosis. The lowest percentage of diagnosed infection was among MSM aged 13-24 years (55%). Among MSM with a likely PrEP indication, discussions about PrEP with a provider and PrEP use were lower among Black MSM (47% and 27%, respectively) and Hispanic/Latino MSM (45% and 31%) than among White MSM (59% and 42%). Among MSM with an HIV diagnosis, adherence to ART and viral suppression were lower among Black MSM (48% and 62%, respectively) and Hispanic/Latino MSM (59% and 67%) compared with White MSM (64% and 74%). Experiences of HIV-related stigma among those with an HIV diagnosis were higher among Black MSM (median = 33; scale = 0-100) and Hispanic/Latino MSM (32) compared with White MSM (26). MSM aged 18-24 years had the lowest adherence to ART (45%) and the highest median stigma score (39). CONCLUSION: Improving access to and use of HIV services for MSM, especially Black MSM, Hispanic/Latino MSM, and younger MSM, and addressing social determinants of health, such as HIV-related stigma, that contribute to unequal outcomes will be essential to end the HIV epidemic in the United States.

Age-Related Differences in Past or Present Hepatitis C Virus Infection Among People Who Inject Drugs: National Human Immunodeficiency Virus Behavioral Surveillance, 8 US Cities, 2015.

BACKGROUND: Historically, older people who inject drugs (PWID) have had the highest hepatitis C virus (HCV) burden; however, young PWID now account for recent increases. We assessed factors associated with past or present HCV infection (HCV antibody [anti-HCV] positive) among young (≤35 years) and older (>35 years) PWID. METHODS: We calculated adjusted prevalence ratios (aPRs) and 95% confidence intervals (CIs) to examine sociodemographic and past 12-month injection behaviors associated with HCV infection. RESULTS: Of 4094 PWID, 55.2% were anti-HCV positive. Among young PWID, anti-HCV prevalence was 42.1% and associated with ≤high school diploma/General Education Development diploma (GED) (aPR, 1.17 [95% CI, 1.03-1.33]), receptive syringe sharing (aPR, 1.37 [95% CI, 1.21-1.56]), sharing injection equipment (aPR, 1.16 [95% CI, 1.01-1.35]), arrest history (aPR, 1.14 [95% CI, 1.02-1.29]), and injecting speedball (aPR, 1.37 [95% CI, 1.16-1.61]). Among older PWID, anti-HCV prevalence was 62.2% and associated with ≤high school diploma/GED (aPR, 1.08 [95% CI, 1.02-1.15]), sharing injection equipment (aPR, 1.08 [95% CI, 1.02-1.15]), high injection frequency (aPR, 1.16 [95% CI, 1.01-1.34]), and injecting speedball (aPR, 1.09 [95% CI, 1.01-1.16]). CONCLUSIONS: Anti-HCV prevalence is high among PWID and varies with age. Scaling up direct-acting antiviral treatment, syringe service programs, and medication-assisted therapy is critical to mitigating transmission risk and infection burden.

Trends in Sexual Risk Behaviors Among Hispanic/Latino Men Who Have Sex with Men - 19 Urban Areas, 2011-2017.

Correct and consistent condom use and human immunodeficiency virus (HIV) preexposure prophylaxis (PrEP) are protective against sexual transmission of HIV (1,2). The incidence of HIV infection among Hispanic/Latino men who have sex with men (MSM) in the United States is increasing (3). HIV risk among Hispanic/Latino MSM differs based on their place of birth and years of U.S. residence (4). Data from CDC's National HIV Behavioral Surveillance (NHBS)* for 2011-2017 were analyzed to assess changes in sexual risk behaviors among Hispanic/Latino MSM by place of birth and years of U.S. residence. Overall, condomless anal sex during the previous 12 months increased from 63% in 2011 to 74% in 2017, and PrEP use during the previous 12 months increased from 3% in 2014 to 24% in 2017. Regardless of place of birth, nearly 75% of Hispanic/Latino MSM reported condomless anal sex during 2017. However, because of PrEP use, <60% of non-U.S.-born Hispanic/Latino MSM and <50% of U.S.-born Hispanic/Latino MSM reported unprotected anal sex (condomless anal sex and no PrEP use) during 2017. Results indicate that PrEP can be a vital tool for reducing HIV transmission among Hispanic/Latino MSM, especially those who have condomless anal sex. Interventions to prevent HIV acquisition, including increasing PrEP uptake, could address cultural and linguistic needs of Hispanic/Latino MSM, as well as other barriers to prevention of HIV infection typically faced by all MSM.

Changes in HIV Preexposure Prophylaxis Awareness and Use Among Men Who Have Sex with Men - 20 Urban Areas, 2014 and 2017.

In February 2019, the U.S. Department of Health and Human Services proposed a strategic initiative to end the human immunodeficiency (HIV) epidemic in the United States by reducing new HIV infections by 90% during 2020-2030* (1). Phase 1 of the Ending the HIV Epidemic initiative focuses on Washington, DC; San Juan, Puerto Rico; and 48 counties where the majority of new diagnoses of HIV infection in 2016 and 2017 were concentrated and on seven states with a disproportionate occurrence of HIV in rural areas relative to other states.† One of the four pillars in the initiative is protecting persons at risk for HIV infection using proven, comprehensive prevention approaches and treatments, such as HIV preexposure prophylaxis (PrEP), which is the use of antiretroviral medications that have proven effective at preventing infection among persons at risk for acquiring HIV. In 2014, CDC released clinical PrEP guidelines to health care providers (2) and intensified efforts to raise awareness and increase the use of PrEP among persons at risk for infection, including gay, bisexual, and other men who have sex with men (MSM), a group that accounted for an estimated 68% of new HIV infections in 2016 (3). Data from CDC's National HIV Behavioral Surveillance (NHBS) were collected in 20 U.S. urban areas in 2014 and 2017, covering 26 of the geographic areas included in Phase I of the Ending the HIV Epidemic initiative, and were compared to assess changes in PrEP awareness and use among MSM. From 2014 to 2017, PrEP awareness increased by 50% overall, with >80% of MSM in 17 of the 20 urban areas reporting PrEP awareness in 2017. Among MSM with likely indications for PrEP (e.g., sexual risk behaviors or recent bacterial sexually transmitted infection [STI]), use of PrEP increased by approximately 500% from 6% to 35%, with significant increases observed in all urban areas and in almost all demographic subgroups. Despite this progress, PrEP use among MSM, especially among black and Hispanic MSM, remains low. Continued efforts to improve coverage are needed to reach the goal of 90% reduction in HIV incidence by 2030. In addition to developing new ways of connecting black and Hispanic MSM to health care providers through demonstration projects, CDC has developed resources and tools such as the Prescribe HIV Prevention program to enable health care providers to integrate PrEP into their clinical care.§ By routinely testing their patients for HIV, assessing HIV-negative patients for risk behaviors, and prescribing PrEP as needed, health care providers can play a critical role in this effort.

Nonprescription Hormone Use Among Transgender Women - National HIV Behavioral Surveillance Among Transgender Women, Seven Urban Areas, United States, 2019-2020.

Certain transgender women who seek gender-affirming hormone treatment (GAHT) face economic and social barriers that limit or prevent access to medically supervised GAHT. Transgender women facing such barriers might acquire GAHT without prescription, potentially without proper dosage, administration, and health monitoring in the absence of medical supervision. For this report, survey data were analyzed from 1,165 transgender women in seven urban areas in the United States to examine associations between self-reported use of nonprescription GAHT and known correlates of nonprescription GAHT, including cost, insurance coverage for GAHT, homelessness, receiving money or drugs in exchange for sex during the past 12 months (exchange sex), lack of comfort discussing gender with provider, and lack of health care use. After controlling for complex sampling design, transgender women who reported recent health care use or insurance coverage for GAHT were less likely to report nonprescription GAHT, and those reporting recent exchange sex or recent homelessness were more likely to report nonprescription GAHT. Findings suggest that transgender women were more likely to use GAHT without a prescription in situations of economic and social marginalization (e.g., disengagement from health care, lack of insurance or trans-specific health care, homelessness, or engagement in sex work). Public health professionals can use these results to design effective interventions to facilitate prescribed hormone use among transgender women in the United States, although access to housing, trans-affirming health care, and insurance coverage might be needed to prevent nonprescription use.

Structural and Psychosocial Syndemic Conditions and Condomless Anal Intercourse Among Transgender Women - National HIV Behavioral Surveillance Among Transgender Women, Seven Urban Areas, United States, 2019-2020.

Psychosocial and structural syndemic conditions, including polydrug use and experiencing homelessness, frequently co-occur and might jointly increase HIV risk. Limited studies have assessed racial and ethnic differences in exposure to syndemic conditions and behaviors associated with HIV transmission among transgender women. This report examines the relation between syndemic conditions and condomless anal intercourse (CAI) among transgender women in seven urban areas in the United States to develop HIV prevention interventions for transgender women. During 2019-2020, transgender women in seven urban areas were recruited using respondent-driven sampling for a biobehavioral survey. Reported syndemic conditions (psychosocial: polydrug use, sexual violence, and psychological distress; structural: homelessness, incarceration, and exchange sex) were summed to create a syndemic score. Using modified Poisson regression to account for RDS, the study assessed whether the strength of the association between syndemic score and CAI differed by race and ethnicity. To assess additive interaction, the relative excess prevalence owing to interaction (REPI) and 95% CIs for selected pairs of syndemic conditions on CAI prevalence stratified by race and ethnicity were estimated. Of 1,348 transgender women (Black = 546, White = 176, and Hispanic = 626), 55% reported CAI; and 24% reported ≥3 syndemic conditions. Reporting additional syndemic conditions was associated with CAI for White, Hispanic, and Black participants. The association was significantly stronger for White than Black and Hispanic participants. Limited significant superadditive interactions were found, although the majority were between structural syndemic conditions. Racial and ethnic differences in REPI estimates were observed. Reporting more syndemic conditions was associated with increased CAI across racial and ethnic groups, demonstrating that HIV prevention efforts for transgender women should address structural and psychosocial syndemic conditions. Results differed by race and ethnicity, indicating that syndemic-focused interventions for transgender women should be tailored to racial and ethnic groups.

Overview and Methodology of the National HIV Behavioral Surveillance Among Transgender Women - Seven Urban Areas, United States, 2019-2020.

Transgender women, especially transgender women of color, are disproportionately affected by HIV. However, no surveillance system collects data on HIV risk factors among this population. To address this gap, CDC developed a surveillance system entitled National HIV Behavioral Surveillance Among Transgender Women (NHBS-Trans) to assess behavioral and contextual data through systematic biobehavioral surveillance to monitor behavioral risk factors, prevention usage, and HIV prevalence among transgender women. NHBS-Trans used respondent-driven sampling in seven urban areas in the United States. Trained interviewers used a standardized, anonymous questionnaire to collect information on HIV-related behavioral risk factors, HIV testing, and use of prevention services. Each of the seven participating project areas recruited approximately 200 eligible transgender women and offered anonymous HIV testing. Overall, in the seven project areas, 1,757 participants completed the eligibility screener for NHBS-Trans during 2019-2020; of these, 6.6% were seeds (i.e., a limited number of initial participants who were chosen by referrals from persons and community-based organizations who knew or were part of the local population of transgender women). A total of 1,637 (93.2%) participants were eligible, consented, and completed the interview. Of these, 1,624 (99.2%) agreed to HIV testing. Of the total 1,637 participants, 29 participants did not report identity of woman or transgender woman, resulting in a final sample of 1,608 transgender women. NHBS-Trans project area staff members (n = 14) reported that the survey was timely and addressed a critical need for HIV surveillance in a population that is often overlooked. The MMWR supplement includes this overview report on NHBS-Trans, which describes the methods (history, participant eligibility criteria, questionnaire, data collection, and HIV testing) as well as evaluation of project implementation and the performance of the questionnaire content, specifically the acceptability for transgender women. The other NHBS-Trans reports in the supplement include information on pre-exposure prophylaxis use, psychosocial syndemic conditions and condomless anal intercourse, nonprescription hormone use, homelessness, discrimination and the association between employment discrimination and health care access and use, and social support and the association between certain types of violence and harassment (gender-based verbal and physical abuse or harassment, physical intimate partner abuse or harassment, and sexual violence) and suicidal ideation. NHBS-Trans provides important data related to the goals of the Ending the HIV Epidemic in the U.S. initiative. Findings from NHBS-Trans can help guide community leaders, clinicians, and public health officials in improving access to and use of HIV prevention and treatment services by transgender women.

Prevalence of Discrimination and the Association Between Employment Discrimination and Health Care Access and Use - National HIV Behavioral Surveillance Among Transgender Women, Seven Urban Areas, United States, 2019-2020.

Transgender women experience discrimination in many settings, including in employment. Because employment and health insurance are intertwined in the United States, employment discrimination might be related to lower health insurance coverage and health care use, including gender-affirming care. This analysis used data from transgender women (N = 1,608) in seven urban areas in the United States collected during 2019-2020 to present the prevalence of six discrimination types (employment, housing, bathroom, businesses, health care, and abuse) and to measure the association between employment discrimination (defined as trouble getting a job or fired due to being transgender) and sociodemographic characteristics, health care access, and health care use. Log-linked Poisson regression models were conducted to estimate adjusted prevalence ratios and 95% CIs. Seven in 10 transgender women experienced at least one type of discrimination during the past 12 months. During the same period, 9.9% of transgender women were fired and 32.4% had trouble getting a job because of being transgender. Employment discrimination was associated with younger age and lower socioeconomic status. Having trouble getting a job was associated with health care access and health care use factors, including having no health insurance or having Medicaid only, having an unmet medical need because of cost, never having transgender-specific care, and having an unmet need for gender-affirming procedures. These findings suggest that employment discrimination contributes to transgender women's economic marginalization and their ability to obtain adequate health insurance coverage and achieve their transition goals. These findings might help guide efforts that protect transgender women's right to pursue their work, health, and life goals without discrimination.

Transgender Women Experiencing Homelessness - National HIV Behavioral Surveillance Among Transgender Women, Seven Urban Areas, United States, 2019-2020.

Transgender women experience high prevalence of homelessness, which can affect their likelihood of acquiring HIV infection and can lead to poor medical outcomes. CDC analyzed data from the National HIV Behavioral Surveillance Among Transgender Women to identify whether personal characteristics and social factors affecting transgender women were associated with duration of homelessness during the past 12 months. Longer duration and chronic homelessness might indicate greater unmet needs, which increases their likelihood for acquiring HIV infection. Ordinal logistic regression was conducted to calculate adjusted prevalence odds ratios and 95% CIs for transgender women from seven urban areas in the United States experiencing homelessness 30-365 nights, 1-29 nights, and zero nights during the past 12 months. Among 1,566 transgender women, 9% reported 1-29 nights homeless and 31% reported 30-365 nights homeless during the past 12 months. Among participants who reported physical intimate partner violence or forced sex, 50% and 47%, respectively, reported experiencing 30-365 nights homeless. Furthermore, 55% who had been evicted or denied housing because of their gender identity and 58% who had been incarcerated during the past year experienced 30-365 nights homeless. The odds of transgender women experiencing longer duration of homelessness was associated with being younger and having a disability; higher psychological distress scores were associated with longer duration of homelessness. Analysis of social determinants of health found transgender women experiencing longer homelessness to be less educated, living below the Federal poverty level, and having lower social support. Therefore, focusing on HIV prevention and interventions addressing housing instability to reduce the duration of homelessness among transgender women is important. Further, integrating housing services with behavioral health services and clinical care, specifically designed for transgender women, could reduce HIV acquisition risk and improve HIV infection outcomes.

Disparities in School Connectedness, Unstable Housing, Experiences of Violence, Mental Health, and Suicidal Thoughts and Behaviors Among Transgender and Cisgender High School Students - Youth Risk Behavior Survey, United States, 2023.

Transgender high school students (those whose gender identity differs from their sex assigned at birth) experience disparate health outcomes and challenges in school, including violence and discrimination, compared with cisgender students (those whose gender identity aligns with their sex assigned at birth). Until recently, population-based data describing the experiences of transgender students and students questioning whether they are transgender (questioning) have been limited. In 2023, the national Youth Risk Behavior Survey assessed transgender identity, providing the first nationally representative data about transgender students. This report describes the demographic characteristics of transgender and questioning high school students and examines differences in the prevalence of experiences of violence, poor mental health, suicidal thoughts and behaviors, school connectedness, and unstable housing among transgender, questioning, and cisgender high school students nationwide. In 2023, 3.3% of U.S. high school students identified as transgender, and 2.2% identified as questioning. Transgender and questioning students experienced a higher prevalence of violence, poor mental health, suicidal thoughts and behaviors, and unstable housing, and a lower prevalence of school connectedness than their cisgender peers. Compared with 8.5% of cisgender male students, 25.3% of transgender students and 26.4% of questioning students skipped school because they felt unsafe. An estimated 40% of transgender and questioning students were bullied at school, and 69% of questioning students and 72% of transgender students experienced persistent feelings of sadness or hopelessness, a marker for experiencing depressive symptoms. Approximately 26% of transgender and questioning students attempted suicide in the past year compared with 5% of cisgender male and 11% of cisgender female students. Intervention opportunities for schools to create safer and more supportive environments for transgender and questioning students can help address these disparities. The findings of this report suggest that more effort is necessary to ensure that the health and well-being of youths who are socially marginalized is prioritized.

Asking for Verbal Sexual Consent and Experiences of Sexual Violence and Sexual Behaviors Among High School Students - Youth Risk Behavior Survey, United States, 2023.

Adolescents' sexual consent behaviors are critical for developing healthy sexual relationships and preventing experiences of sexual violence. This report uses 2023 Youth Risk Behavior Survey data to describe prevalence of asking for sexual consent verbally at last sexual contact among U.S. high school students. Differences in prevalence of asking for sexual consent verbally by sex, age, race and ethnicity, sexual identity, sex of sexual contacts, and gender identity were examined. Differences in asking for sexual consent verbally also were examined by experiences of sexual violence and sexual behaviors. Sex-stratified logistic regression analyses were performed to determine the association between asking for sexual consent verbally with experiences of sexual violence and sexual behaviors. In addition, data were analyzed using adjusted logistic regression models controlling for age, race and ethnicity, and sexual identity. Among high school students who reported ever having sexual contact, 79.8% reported asking for sexual consent verbally at last sexual contact. A lower percentage of female students (74.5%) reported asking for sexual consent verbally than male students (84.6%). In adjusted sex-stratified analyses, female students who asked for sexual consent verbally had higher prevalence of ever having had sexual intercourse. Male students who asked for sexual consent verbally had higher prevalence of ever having had sexual intercourse and being currently sexually active. Female and male students who asked for sexual consent verbally had higher prevalence of having first sexual intercourse before age 13 and using condoms. In addition, female students who asked for sexual consent verbally during last sexual intercourse had lower prevalence of using alcohol or drugs at last sexual intercourse. Public health researchers and practitioners, health care providers, schools, and youth-serving organizations can use these findings to better understand high school students' verbal sexual consent, improve complex measurement of consent-seeking behaviors, and guide multicomponent sexual health and violence prevention efforts across various settings.

Adult Caretaker Engagement and School Connectedness and Association with Substance Use, Indicators of Emotional Well-Being and Suicide Risk, and Experiences with Violence Among American Indian or Alaska Native High School Students - Youth Risk Behavior Survey, United States, 2023.

The strength of American Indian and Alaska Native (AI/AN) communities comes from generations of Indigenous traditions, language, culture, and knowledge. These strengths have been challenged by a complex set of systemic, structural, and social factors related to historical and intergenerational trauma that affects the health of AI/AN communities. Furthermore, AI/AN population health data often are inaccurate because of analytic coding practices that do not account for multiracial and ethnic AI/AN identification and inadequate because of statistical suppression. The 2023 national Youth Risk Behavior Survey included a supplemental sample of AI/AN high school students. Coding of race and ethnicity was inclusive of all AI/AN students, even if they also identified as another race or as Hispanic or Latino, providing comprehensive data on health behaviors and experiences among AI/AN high school students nationwide. Adult caretaker engagement and school connectedness and their association with 13 health behaviors and experiences were examined, including five types of current substance use, four indicators of emotional well-being and suicide risk, and four types of violence. Pairwise t-tests and adjusted prevalence ratios from logistic regression models identified significant associations between exposure and outcome variables. Among AI/AN students, having an adult who always tried to meet their basic needs, high parental monitoring, and high school connectedness were associated with lower prevalence of certain measures of substance use, poor emotional well-being and suicide risk, and violence. Compared with non-AI/AN students, the prevalence of current electronic vapor product use, current marijuana use, attempted suicide, and experience of sexual violence was higher among AI/AN students.This report presents the most comprehensive, up-to-date data on substance use, indicators of emotional well-being and suicide risk, and experiences with violence among AI/AN high school students nationwide. The findings suggest the importance of engaged household adults and school connectedness in promoting emotional well-being and preventing substance use, suicide-related behavior, and experiences of violence among AI/AN students. Understanding the historical context and incorporating Indigenous knowledge when developing interventions focused on AI/AN youths are critical to ensure such interventions are successful in improving AI/AN health and well-being.

Overview and Methods for the Youth Risk Behavior Surveillance System - United States, 2023.

The Youth Risk Behavior Surveillance System (YRBSS) is a set of surveys that tracks a broad range of behaviors, experiences, and conditions that can lead to poor health among high school students. The system includes a nationally representative Youth Risk Behavior Survey (YRBS) and separate school-based YRBSs conducted by states, tribes, territories, and local school districts. For the 2023 national YRBS, CDC made changes to the sampling method, survey administration mode, and questionnaire. Specifically, the sampling design added an American Indian or Alaska Native (AI/AN) supplemental sample so that separate, precise estimates could be made for AI/AN high school students, in addition to the usual sample designed to provide nationally representative data for the population of students in grades 9-12. To decrease the time needed to collect and process data, CDC changed the survey administration mode from paper-and-pencil scannable booklets to a tablet-based electronic survey. To provide national data on topics of emerging interest, CDC added new questions to the questionnaire. These new questions assessed social media use, experiences of racism at school, adverse childhood experiences, transgender identity, consent for sexual contact, and unfair discipline at school. Public health practitioners and researchers can use YRBSS data to examine the prevalence of youth health behaviors, experiences, and conditions; monitor trends; and guide interventions. This overview report describes 2023 YRBSS survey methodology, including sampling, data collection, data processing, weighting, and data analyses. The 2023 YRBS participation map, survey response rates, and a detailed examination of student demographic characteristics are included in this report. During 2023, in addition to the national YRBS, 68 site-level surveys were administered to high school students in 39 states, three tribal governments, five territories, and 21 local school districts. These site-level surveys use site-specific questionnaires that are similar to the national YRBS questionnaire but are modified to meet sites' needs. This overview and methods report is one of 11 featured in this MMWR supplement, which reports results from the 2023 national YRBS but does not include data from the 68 site-level surveys. Each report is based on data collected using methods presented in this overview report. A full description of YRBSS results and downloadable data are available (https://www.cdc.gov/yrbs/index.html).

AIDS or HIV Education and Sexual Behaviors Among Adolescent Sexual Minority Males: National HIV Behavioral Surveillance, 3 U.S. Cities, 2015.

In the U.S., HIV transmission rates have increased among male-male sexual contacts. Sex education reduces HIV-related risks; yet impacts for adolescent sexual minority males (ASMM) are less known. Data from a sample (n = 556) of ASMM (aged 13-18) in three U.S cities were used to examined associations between HIV education in school and sexual behaviors. Outcomes of interest included: sexually transmitted infection (STI), multiple sex partners, and condomless anal intercourse (CAI) with a male (all past 12 months). Adjusted prevalence ratios (aPR) and 95% confidence intervals (CI) were calculated. Of 556 ASMM, 84% reported received HIV education. Among sexually active ASMM (n = 440) who received HIV education, fewer reported an STI (10% vs. 21%, aPR: 0.45, CI [0.26, 0.76]) and CAI (48% vs. 64%, aPR: 0.71, CI [0.58, 0.87]) than ASMM who did not receive HIV education. Protective effects of school HIV education on sexual behaviors are promising and suggest prevention education is vital to reducing HIV- and STI-related risks among ASMM.

Prevalence of and racial/ethnic differences in sexuality disclosure among men who have sex with men in 23 U.S. cities-National HIV Behavioral Surveillance, 2017.

Sexuality disclosure among men who have sex with men (MSM) is key in access to HIV prevention services. We used weighted 2017 data from National HIV Behavioral Surveillance to investigate prevalence of, and racial/ethnic differences in, sexuality disclosure among MSM. Of 10,753 MSM, 89.4% (95% CI: 88.5-90.3%) had disclosed their sexuality to any non-lesbian, gay, or bisexual (LGB) friends, 85.9% (95% CI: 84.8-87.0%) had disclosed their sexuality to any family members, and 82.8% (95% CI: 81.6-83.9%) had disclosed their sexuality to any health care providers. Although most MSM had disclosed, 23.8% (95% CI: 22.4-25.1%) had not disclosed to at least one of the three groups. Black, Hispanic/Latino, or Asian MSM were less likely than White MSM to have disclosed their sexuality to any non-LGB friends, any family members, or any health care providers, after adjusting for age and region. We found high prevalence of sexuality disclosure among MSM, but racial/ethnic differences persist. Strategies and interventions to promote sexuality disclosure among MSM are needed.

Material Hardship and Association With Sexual Risk Behavior Among Adolescent Sexual Minority Males in 3 US Cities-National HIV Behavioral Surveillance-Young Men Who Have Sex With Men, 2015.

INTRODUCTION: Adolescent sexual minority males (ASMMs) are disproportionately affected by HIV relative to other youth within the United States. Social determinants of health have been explored among this population; however, economic determinants, such as material hardship, remain understudied. We examined the relationship between material hardship and sexual behavior among ASMMs aged 13-18 years residing in 3 US cities using 2015 data from CDC's National HIV Behavioral Surveillance among Young Men Who Have Sex with Men. METHODS: Young men ages 13-18 years residing in 3 US cities were recruited through venue-based, respondent-driven, or Facebook sampling. We estimated adjusted prevalence ratios (aPRs) with 95% confidence intervals (CIs) for condomless anal intercourse (CAI) with a male sex partner in the past 12 months and with having 4 or more male sex partners in the past 12 months. RESULTS: Of 547 ASMMs, 27% reported experiencing material hardship in the past 12 months. After adjusting for demographics, household characteristics, and city, ASMMs who experienced material hardship were more likely to report CAI with a male partner in the past 12 months (aPR: 1.55, 95% CI: 1.25 to 1.93) and to have had 4 or more male sex partners in the past 12 months (aPR: 1.44, 95% CI: 1.08 to 1.91). DISCUSSION: More than a quarter of ASMMs experienced material hardship that was associated with increased sexual risk behavior among ASMMs. Incorporating services that address all unmet needs is important to consider for HIV prevention efforts for ASMMs.

Family Factors and HIV-Related Risk Behaviors Among Adolescent Sexual Minority Males in Three United States Cities, 2015.

Purpose: We examined the relationship between family factors and HIV-related sexual risk behaviors among adolescent sexual minority males (ASMM) who are affected disproportionately by HIV. Methods: We analyzed results from the National HIV Behavioral Surveillance among Young Men Who Have Sex with Men. Adolescent males ages 13-18 who identified as gay or bisexual, or who reported attraction to or sex with males were interviewed in 2015 in Chicago, New York City, and Philadelphia. Separate log-linked Poisson regression models were used to estimate associations between family factors and sexual risk behaviors. Results: Of the 569 ASMM, 41% had condomless anal intercourse in the past 12 months, 38% had ≥4 male sex partners in the past 12 months, and 23% had vaginal or anal sex before age 13. ASMM who had ever been kicked out of their house or run away, those who were out to their mother, and those who were out to their father, were more likely to engage in sexual risk behaviors. ASMM who were currently living with parents or guardians and those who received a positive reaction to their outness by their mother were less likely to engage in sexual risk behaviors. Conclusion: Our findings highlight the important role of family factors in HIV risk reduction among ASMM. A better understanding of the complex dynamics of these families will help in developing family-based interventions.
