Introduction: Secondary distribution of HIV self‐tests (HIVST) by HIV‐negative pregnant women to male partners increases men's testing rates. We examined whether this strategy promotes male partner testing for pregnant women living with HIV (PWLHIV). Methods: We conducted an open‐label individually randomized trial in Kampala, Uganda, in which PWLHIV ≥18 years who reported a partner of unknown HIV status were randomized 2:1 to secondary distribution of HIVST for male partner(s) or standard‐of‐care (SOC; invitation letter to male partner for fast‐track testing). Women were followed until 12 months post‐partum. Male partners were offered confirmatory HIV testing and facilitated linkage to antiretroviral treatment (ART) or oral pre‐exposure prophylaxis (PrEP). Using intention‐to‐treat analysis, primary outcomes were male partner testing at the clinic and initiation on PrEP or ART evaluated through 12 months post‐partum (ClinicalTrials.gov, NCT03484533). Results: From November 2018 to March 2020, 500 PWLHIV were enrolled with a median age of 27 years (interquartile range [IQR] 23–30); 332 were randomized to HIVST and 168 to SOC with 437 PWLHIV (87.4%) completing 12 months follow‐up post‐partum. Of 236 male partners who tested at the clinic and enrolled (47.2%), their median age was 31 years (IQR 27–36), 45 (88.3%) men with HIV started ART and 113 (61.1%) HIV‐negative men started PrEP. There was no intervention effect on male partner testing (hazard ratio [HR] 1.04; 95% confidence interval [CI]: 0.79–1.37) or time to ART or PrEP initiation (HR 0.96; 95% CI: 0.69–1.33). Two male partners and two infants acquired HIV for an incidence of 0.99 per 100 person‐years (95% CI: 0.12–3.58) and 1.46 per 100 person‐years (95% CI: 0.18%–5.28%), respectively. Social harms related to study participation were experienced by six women (HIVST = 5, SOC = 1). Conclusions: Almost half of the partners of Ugandan PWLHIV tested for HIV with similar HIV testing rates and linkage to ART or PrEP among the secondary distribution of HIVST and SOC arms. Although half of men became aware of their HIV serostatus and linked to services, additional strategies to reach male partners of women in antenatal care are needed to increase HIV testing and linkage to services among men.

Introduction: Increased HIV testing by men in sub‐Saharan Africa is key to meeting UNAIDS 2025 testing targets. Secondary distribution of HIV self‐testing (HIVST) kits by pregnant women attending antenatal care to male partners has been shown to increase testing among African men. A detailed understanding of how women and male partners manage the distribution and use of HIVST and subsequent linkage to clinic‐based follow‐up can inform implementation and scale‐up efforts. Methods: We use qualitative data from the Obumu Study, a randomized trial of secondary distribution of HIVST by pregnant women living with HIV to male partners in Kampala, Uganda, to unpack the HIVST delivery process. The protocol included a clinic visit by male partners to confirm HIVST results. Individual interviews eliciting data on experiences of delivering and using HIVST and of subsequent linkage to clinic‐based testing were conducted with a purposefully selected sample of 45 women and 45 male partner Obumu Study participants from November 2018 to March 2021. Interview data from 59 participants (29 women and 30 men) in the HIVST arm were analysed through coding and category construction. Results: Women living with HIV were apprehensive about delivering HIVST to their partners, especially if they had not disclosed their HIV status. They invested effort in developing strategies for introducing HIVST. Male partners described a range of responses to receiving the self‐testing kit, especially fear of a positive test result. Women reported leading the self‐testing process, often conducting the test themselves. Most women confidently interpreted HIVST results. However, they tended to defer to healthcare workers rather than report positive results directly to partners. Women told their partners the testing process required a clinic follow‐up visit, often without explaining the visit's purpose. Many partners delayed the visit as a result. Women again responded by strategizing to persuade their partners to link to follow‐up care. Conclusions: Secondary distribution of HIVST by pregnant women living with HIV to male partners can be challenging, especially when women have not disclosed their HIV status. Additional support may alleviate the burden; outreach to male partners may facilitate linkage to confirmatory testing and HIV care or prevention. [ABSTRACT FROM AUTHOR]
