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. A total of 710 male sex workers were recruited in the study.

This dataset was generated through the intake survey administered in male sex workers in Vietnam in a clinical, private atmosphere after selection for the intervention. The intake interview included formal assessments of alcohol use (AUDIT), anxiety/stress (DASS-21), depression (CESD-20), sexual history, current sexual practices (with male elective partners, female elective partners, and male sex work clients), a detailed assessment of their last male sex work event, and self-reported health status and use of health services. The dataset is tied to the Cross-Sectional Survey 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.
