Physical and sexual violence, childhood sexual abuse and HIV/STI risk behaviour among alcohol-using women engaged in sex work in Mongolia

Abstract

Although the prevalence of human immunodeficiency virus (HIV) in Mongolia is low, it could increase without strategic prevention strategies. Female sex workers (FSWs) often experience barriers to prevention, including interpersonal violence. This study investigated if childhood sexual abuse (CSA) or recent physical or sexual violence was associated with HIV sexual risk behaviours and if CSA modified associations between recent violence and HIV sexual risk behaviours. Two-hundred twenty-two women who (1) were at least 18 years old and clients at the National AIDS Foundation; (2) reported vaginal or anal sex in the past 90 days in exchange for money or goods and (3) met criteria for harmful alcohol use in the past year were enrolled. In-person interviews assessed sexual risk behaviours and violence in childhood and adulthood. Negative binomial regression, ordinary least squares regression and modified Poisson regression were performed. Sexual risk with paying partners was associated with penetrative CSA and sexual violence by paying partners. CSA and recent violence were not associated with sexual risk behaviours with intimate partners. CSA modified the association between recent sexual violence and unprotected sex with intimate partners. Findings highlight the need for integrated violence and sexual risk reduction services to ensure safe and effective prevention for FSWs.

Notes

1. Because the sample size for intimate partners is 98 and the sample size for paying partners is 222, the analyses are limited to estimating the association of violence from intimate partners and sexual behaviours with intimate partners (n = 98), and the association of violence from paying partners and sexual behaviours with paying partners (n = 222). Analyses do not combine intimate and paying partners.
