Men who have sex with men (MSM) in developing countries such as Mexico have received relatively little research attention. In Tijuana, Mexico, a border city experiencing a dynamic HIV epidemic, data on MSM are over a decade old. Our aims were to estimate the prevalence and examine correlates of HIV infection among MSM in this city. Methods We conducted a cross‐sectional study of 191 MSM recruited through respondent‐driven sampling (RDS) in 2012. Biological males over the age of 18 who resided in Tijuana and reported sex with a male in the past year were included. Participants underwent interviewer‐administered surveys and rapid tests for HIV and syphilis with confirmation. Results A total of 33 MSM tested positive for HIV, yielding an RDS‐adjusted estimated 20% prevalence. Of those who tested positive, 89% were previously unaware of their HIV status. An estimated 36% (95% CI: 26.4–46.5) had been tested for HIV in the past year, and 30% (95% CI: 19.0–40.0) were estimated to have ever used methamphetamine. Independent correlates of being infected with HIV were methamphetamine use (odds ratio [OR]=2.24, p =0.045, 95% CI: 1.02, 4.92) and active syphilis infection (OR=4.33, p =0.01, 95% CI: 1.42, 13.19). Conclusions Our data indicate that MSM are a key sub‐population in Tijuana at higher risk for HIV. Tijuana would also appear to have the highest proportion among upper‐middle‐income countries of HIV‐positive MSM who are unknowingly infected. More HIV prevention research on MSM is urgently needed in Tijuana.
