Do men who have sex with men who report alcohol and illicit drug use before/during sex (chemsex) present moderate/high risk for substance use disorders?

Background: We evaluated the prevalence of sexualized drug use (Chemsex) and its association with moderate/high risk for substance use disorders and HIV sexual risk behavior among men who have sex with men (MSM).

Methods: We conducted a cross-sectional web-based survey among MSM from Rio de Janeiro (Brazil). The Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) was used to screen people at moderate/high-risk for substance use disorders.

Development of a Social Network-Based Intervention to Overcome Multilevel Barriers to ART Adherence Among Adolescents in Brazil.

Brazil's comprehensive HIV treatment program does not specifically address ART adherence challenges for adolescents-a group accounting for the largest number of incident HIV infections in Brazil. We conducted three focus groups with 24 adolescents (age 15-24) living with HIV in Rio de Janeiro, separately for cisgender men who have sex with men, heterosexual-identified cisgender men and women, and transgender women of any sexual orientation, and key informant interviews (n = 7) with infectious disease specialists and HIV/AIDS service organization staff. Content analysis identified socioecological barriers and facilitators to adherence, including individual (e.

Barriers and facilitators to PrEP for transwomen in Brazil.
