Access to Oral Fluid-Based Human Immunodeficiency Virus Self-Tests Increases Testing Among Male Partners of Adolescent Girls in Kenya: A Randomized Controlled Trial

Purpose: The risk of human immunodeficiency virus (HIV) among adolescent girls (AGs) may be reduced if they know the HIV status of their male partners. We assessed the ability of AGs in Siaya County, Kenya, to offer HIV self-tests to their partners to promote partner and couples testing. Methods: Eligible AGs were 15–19 years old, self-tested HIV-negative, and had a male partner not tested in the past 6 months. Participants were randomly assigned to receive two oral fluid-based self-tests (intervention arm) or a referral coupon for facility-based testing (comparison arm). The intervention included counseling on ways to safely introduce self-tests to partners. Follow-up surveys were conducted within 3 months. Results: Among 349 AGs enrolled, median age was 17 years (interquartile range 16–18), 88.3% of primary partners were noncohabiting boyfriends, and 37.5% were unaware if their partner had ever tested. At 3 months, 93.9% of the intervention arm and 73.9% of the comparison arm reported that partner testing occurred. Compared to the comparison arm, partner testing was more likely in the intervention arm (risk ratio = 1.27; 95% confidence interval 1.15–1.40; p < .001). Among participants whose partners got tested, 94.1% and 81.5% in the intervention and comparison arms, respectively, reported that couples testing occurred; couples testing was more likely in the intervention than comparison arm (risk ratio = 1.15; 95% confidence interval 1.15–1.27; p = .003). Five participants reported partner violence, one study-related. Discussion: Provision of multiple self-tests to AGs for the purpose of promoting partner and couples testing should be considered in Kenya and other settings where AGs face a high risk of HIV acquisition.
