Epidemiology of sexual health in the virtual environment: A multinational online survey of Spanish- and portuguese-speaking men who use an internet sexual networking site

There is limited data on the sexual health of users of sexual networking websites for men who have sex with men (MSM) in Latin America. Members of a MSM-targeted social/sexual networking website in Latin America, Spain, and Portugal participated in an online sexual health survey. Among 36,063 respondents, nearly 90 % reported having anal or vaginal intercourse in the past 3 months. Among sexually active men, 53.2 % used condoms inconsistently. In the past year, 54 % of respondents reported undergoing sexually transmitted infections (STI) testing and 67 % reported testing yearly or more often for HIV. Self-reported HIV prevalence was 9.1 %. Differences were seen by geographic region. Unprotected intercourse with partners of different or unknown HIV status was associated with recent STI diagnosis (OR = 1.83, t = 13.15, d.f. = 21, p <.001) and HIV diagnosis (OR = 2.20, t = 14.00, d.f. = 21, p <.001). Online surveys are a promising tool for HIV/STI surveillance and prevention internationally to reach an important subset of MSM.
