Confidentiality concerns are a well-established barrier to sexual health services for adolescents. These barriers are likely even greater for young men who have sex with men (YMSM), who often experience stigma at multiple levels. This study examined the relationship between state laws regulating minors' access to confidential sexual health services, sexual behavior, and lifetime HIV testing among a large, representative sample of sexually active male high school students from the 2019 state-level Youth Risk Behavior Surveillance System (23 states; N = 17,509).

Black women in community supervision programs (CSPs) are disproportionately affected by HIV and other sexually transmitted infections (STIs). A randomized controlled trial of a group intervention titled Empowering African-American Women on the Road to Health (E-WORTH) demonstrated effectiveness in reducing sexual risk behaviors and STI incidence among Black women in CSPs. This secondary analysis aimed to assess the moderating effects of housing status and food security on E-WORTH effectiveness in reducing sexual risk behaviors and cumulative incidence of STIs over a 12-month period which were found significant in the original trial among a sample of 351 Black women in CSPs in New York City who use drugs and/or engage in binge drinking who reported engaging in HIV risk behaviors or testing positive for HIV.

Background: Black women involved in the legal system disproportionately experience intimate partner violence (IPV); however, current research does not satisfactorily describe the risk and protective factors associated with IPV among Black women under community supervision.

Methods: We conducted a subgroup analysis of Black women ( = 128) using data from a randomized controlled trial that evaluated the feasibility and efficacy of two IPV screening and prevention programs for women under community supervision. Participants in the original study were randomized into two IPV prevention conditions-computerized or case manager Women Initiating New Goals of Safety (WINGS).

Since the COVID-19 pandemic, intimate partner violence (IPV) rates have increased in the United States. Although accumulating research has documented the effectiveness of couple-based interventions in reducing HIV/STIs, it remains unclear whether they are effective and safe for couples experiencing IPV. We used moderation analysis from a randomized clinical trial to evaluate whether a couples-based HIV/STI intervention may have differential effectiveness in reducing HIV/STI risks among couples where one or both partners reported experiencing IPV compared to couples without such IPV among a sample of 230 men at risk for HIV/STIs who reported using drugs and were mandated to community supervision settings in New York City and their main female sexual partners.

Stressful life events are prevalent among justice-involved populations and are associated with sexual risk behaviors and partner communication regarding safe-sex practices. We describe patterns of stress exposure for heterosexual couples (where males are under community supervision) and how stress patterns are associated with sexual risk behaviors and communication (460 individuals; 230 couples). Latent class analysis identified patterns of stress.

Introduction: Female sex workers (FSW) who use drugs are a key population at risk of HIV in Kazakhstan, and face multiple structural barriers to HIV prevention. More research is needed on the role of structural interventions such as microfinance (MF) in reducing HIV risk. This paper describes the results of a cluster-randomized controlled trial to test the efficacy of a combination HIVRR + MF intervention in reducing biologically confirmed STIs and HIV risk behaviours.

Importance: Concentrated epidemics of HIV and sexually transmitted infections (STIs) have persisted among Black women in community supervision programs (CSPs) in the United States. Accumulating research has highlighted the effectiveness of culturally tailored HIV/STI interventions for Black women; however, there is a dearth of such interventions for the large number of Black women in CSPs.

Objective: To determine the effectiveness of a 5-session culturally tailored group-based intervention (Empowering African-American Women on the Road to Health [E-WORTH]) with individualized computerized modules and streamlined HIV testing in reducing STIs and condomless sex vs a 1-session streamlined HIV testing control condition.

Importance: In the United States, the prevalence rates of HIV and sexually transmitted infections (STIs) are higher among individuals in community supervision programs (CSPs) than in the general population. However, to date, no couple-based HIV or STI prevention interventions have been implemented for the large number of men in CSPs.

Objective: To determine the effectiveness of a 5-session couple-based prevention intervention, compared with a 1-session counseling, testing, and referral (CTR) program, in reducing HIV and STIs as well as condomless intercourse among men in CSPs and their female sexual partners.

Intimate partner violence (IPV) has emerged as a serious public health issue in migrant communities in Central Asia and globally. To date, however, research on risk factors associated with male perpetration of IPV among migrants remains scant. This study aims to examine risk environment theory-driven factors associated with male perpetration of IPV in the prior 6 months.

Existing research indicates that justice-involved individuals use a variety of different drugs and polysubstance use is common. Research shows that different typologies of drug users, such as polydrug users versus users of a single drug, have differing types of individual-, structural-, and neighborhood-level risk characteristics. However, little research has been conducted on how different typologies of drug use are associated with HIV risks among individuals in community corrections and their intimate sex partners.
