Susceptibility to human immunodeficiency virus (HIV) infection is of particular concern for marginalized populations. The objective of this study was to determine risk factors associated with sex trade work among young gay and bisexual men. Further, we aimed to compare HIV prevalence and incidence among men involved and not involved in sex trade work.
The study is based upon data obtained from a prospective cohort study of young gay and bisexual men. Participants had completed a baseline questionnaire which elicited information on demographic information, sexual behaviours, and substance use. Sex trade involvement was defined as the exchange of money, drugs, goods, clothing, shelter or protection for sex within the one year prior to enrollment. Contingency table and multivariate logistic regression analyses were used to identify risk factors associated with involvement in the sex trade.
Of the 761 eligible participants, 126 (16%) reported involvement in sex trade work. Multivariate logistic regression analysis revealed regular alcohol use (Odds Ratio [OR] = 3.6, 95% CI : 1.8-7.2), aboriginal ethnicity (OR = 3.7, 95% CI : 1.6-8.7), unemployment (OR = 3.9, 95% CI : 2.1-7.3), history of residence in a psychiatric ward (OR = 4.2, 95% CI : 1.8-9.8), bisexual activity (OR = 7.0, 95% CI : 3.5-14.1) and the use of crack (OR = 7.4, 95% CI : 3.0-18.7) to be independently associated with sex trade work. Sex trade workers had a significantly higher HIV prevalence at baseline compared with non-sex trade workers (7.3% versus 1.1%, P
