Resumen:
Objective To determine human immunodeficiency virus (HIV) seroprevalence in a sample
of men who have sex with men (MSM) in Buenos Aires City and to identify risk
factors associated with HIV type 1 infection.
Methods Participants were invited to receive HIV counselling and testing at NEXO (a gay
non-governmental organization) by means of informative leaflets distributed
in gay nightclubs, porno cinemas, gymnasiums, and in the streets. During the
encounter, the study was explained by a trained social worker and individuals
were invited to volunteer for the study. Diagnosis of HIV was performed using
two screening tests and Western Blot assay was used as confirmatory.
Results Human immunodeficiency virus was detected in 96 (13.8%; 95% CI: 11.416.7)
of 694 MSM. Fourteen (14.6%) of the 96 HIV-positive MSM were already aware
of their HIV serostatus. In univariate analysis, HIV-1 infection (odds ratio [OR]
_1.5) was found to be associated with older age (3039 years), being unemployed,
a previous sexually transmitted disease (STD) history, and having an HIV-positive
partner. Cocaine consumption and irregular use of condoms with occasional
partners were also found to be risk factors. In multivariate logistic regression
analysis, being unemployed (OR = 3.42; 95% CI: 1.179.99) and having an HIVpositive
partner (OR = 2.67; 95% CI: 1.096.52) remained significant risk factors.
Discussion The high HIV-1 prevalence observed suggests an urgent need for implementation
of effective prevention campaigns. This represents the first cross-sectional epidemiological
study of HIV among the high-risk group of MSM in Argentina.
