Abstract

Highlights: Approximately 55% of the women in the study were living with HIV. Women in the Women's Health CoOp+ (WHC+) were more likely to use a condom. Women in the WHC+ arm were less likely to engage in frequent heavy drinking. Women in the WHC+ arm were less likely to report all forms of abuse. The WHC+ shows promise for increasing adherence to ARVs among women who use AODs. Abstract: Background: HIV prevalence has increased among South African women who use alcohol and other drugs (AOD). However, HIV prevention and treatment efforts have not focused on this population. This study presents the efficacy of the Women's Health CoOp Plus (WHC+) in a cluster-randomized trial to reduce AOD use, gender-based violence, and sexual risk and to increase linkage to HIV care among women who use AODs, compared with HIV counseling and testing alone. Methods: Black African women (N = 641) were recruited from 14 geographic clusters in Pretoria, South Africa, and underwent either an evidence-based gender-focused HIV prevention intervention that included HIV counseling and testing (WHC+) or HIV counseling and testing alone. Participants were assessed at baseline, 6-months, and 12-months post enrollment. Results: At 6-month follow-up, the WHC+ arm (vs. HCT) reported more condom use with a main partner and sexual negotiation, less physical and sexual abuse by a boyfriend, and less frequent heavy drinking (ps < 0.05). At 12-month follow-up, the WHC+ arm reported less emotional abuse (p < 0.05). Among a subsample of women, the WHC+ arm was significantly more likely to have a non-detectable viral load (measured by dried blood spots; p = 0.01). Conclusion: The findings demonstrate the WHC+'s efficacy to reduce HIV risk among women who use AODs in South Africa. Substance abuse rehabilitation centers and health centers that serve women may be ideal settings to address issues of gender-based violence and sexual risk as women engage in substance use treatment, HIV testing, or HIV care.
