Background: Sexually transmitted infections pose a major public health challenge in the United States and this burden is especially acute in subpopulations like young men who have sex with men (YMSM) and young transgender women (YTW). Yet, the direct behavioral antecedents of these infections are not well understood making it difficult to identify the cause of recent increases in incidence. This study examines how variations in partnership rates and the number of condomless sex acts are associated with STI infections among YMSM-YTW.
Method: This study leveraged 3 years of data from a large longitudinal cohort of YMSM-YTW. A series of generalized linear mixed models examined the association between the number of condomless anal sex acts, number of one-time partners, number of casual partners, and number of main partners and chlamydia, gonorrhea, or any STI.
Results: Results indicated the number of casual partners was associated with gonorrhea [aOR = 1.17 (95% CI: 1.08, 1.26)], chlamydia [aOR = 1.12 (95% CI: 1.05, 1.20)], and any STI [aOR = 1.14 (95% CI: 1.08, 1.21)] while the number of one-time partners was only associated with gonorrhea [aOR = 1.13 (95% CI: 1.02, 1.26)]. The number of condomless anal sex acts was not associated with any outcome.
Conclusion: These findings suggest the number of casual partners is a consistent predictor of STI infection among YMSM-YTW. This may reflect the quick saturation of risk within partnerships making the number of partners, rather than the number of acts, the more relevant factor for STI risk.

Objectives: Doxycycline prophylaxis shows promise for sexually transmitted infection (STI) prevention, but data primarily come from high-income countries. This study assessed awareness, willingness and factors associated with willingness to use doxycycline for STI prevention among men who have sex with men (MSM) using HIV-PrEP in Vietnam.
Methods: Between January 25 and February 4, 2024, a cross-sectional study recruited males aged ≥18 years who reported sex with men in the past 12 months from 11 PrEP clinics in Hanoi and Ho Chi Minh City.

Adolescents in the United States (US) continue to be disproportionately impacted by HIV and STIs. We investigated the associations between sexual health and substance use behaviors with HIV and STI testing among high school students in the US. Cross-sectional weighted stepwise multivariate logistic regression models were conducted to determine the odds of lifetime HIV and STI testing among students, stratified by sex.

Objective: HIV can be effectively prevented by oral HIV pre-exposure prophylaxis (PrEP). When PrEP was introduced, there was apprehension that condom use would decrease and STIs would increase. The purpose of this study was to investigate sexual behaviour and STI incidence among PrEP users.

Background: To date, no randomized controlled trials have specifically addressed behavior changes after HIV self-testing (HIVST) among transgender women.
Objective: This study aims to evaluate the effects of HIVST on changes in HIV testing behavior, frequency of condomless sex, and partner numbers among transgender women in China.
Methods: Participants were recruited from 2 Chinese cities using both online and offline methods.
