This dataset is part of a larger study of male sex workers in Vietnam. The study included a community-based cross-sectional interview and an intake interview. From the cross-sectional interview, a random sample of participants were selected for participation in the sexual health promotion intervention. Intervention participants then completed a more detailed intake interview and received a clinical exam and testing for HIV/STIs, onsite treatment for STIs, vaccinations, and referrals for HIV treatment if positive. Study participants were recruited from public and semi-public venues in Hanoi, Nha Trang, and Ho Chi Ming City, were males aged 16 to 35 years old, and reported having sex with a man in the previous 90 days that involved the expectation of material award.

This dataset was generated through the community-based cross-sectional interview. The community-based cross-sectional interview collected information in the following domains: demographics, lifetime and current substance use, mental health diagnosis and treatment, sexual history, health service utilization, and HIV/STI transmission and treatment knowledge. The dataset is tied to the Intake Interview Data of Male Sex Workers in Vietnam with de-identified study participant identifiers. Participants who received the intervention were also tested for HIV, chlamydia, gonorrhea and syphilis and received a basic clinical exam.
