Introduction The postpartum period can be challenging for women living with HIV. Understanding how the postpartum period impacts ART adherence and condomless sex could inform the development of comprehensive sexual and reproductive health and HIV services tailored to the needs of women living with HIV during this critical interval. Methods In a longitudinal cohort study of HIV-seropositive Kenyan women, late ART refills and self-reported condomless sex were compared between the woman’s pregnancy and the postpartum period. Analyses were conducted using generalized estimating equations and adjusted for alcohol use, depressive symptoms, intimate partner violence (IPV), and having a recent regular partner. Effect modification was explored for selected variables. Results and discussion 151 women contributed visits. Late ART refills occurred at 7% (32/439) of pregnancy visits compared to 18% (178/1016) during the postpartum period (adjusted relative risk [aRR] 2.44, 95% confidence interval [CI] 1.62–3.67). This association differed by women’s education level. Women with ≥8 years of education had late ART refills more during the postpartum period than pregnancy (aRR 3.00, 95%CI 1.95–4.62). In contrast, in women with <8 years of education, late ART refills occurred similarly during pregnancy and the postpartum period (aRR 0.88, 95%CI 0.18–4.35). Women reported condomless sex at 10% (60/600) of pregnancy visits compared to 7% (72/1081) of postpartum visits (aRR 0.76, 95%CI 0.45–1.27). This association differed by whether women had experienced recent IPV. Women without recent IPV had a significant decline in condomless sex from pregnancy to postpartum (aRR 0.53, 95%CI 0.30–0.95) while women with recent IPV had no significant change in condomless sex from pregnancy to postpartum (aRR 1.76, 95%CI 0.87–3.55). Conclusion Improved support for ART adherence during the postpartum period and addressing IPV to limit condomless sex could improve HIV treatment and prevention outcomes for HIV-seropositive women as well as their infants and sexual partners.

BACKGROUND Mobile technology can support HIV care, but studies in youth living with HIV (YLWH) are limited. OBJECTIVE We developed a facilitated WhatsApp group intervention (named Vijana-SMART) for YLWH, grounded in social support theory and guided by YLWH’s design recommendations. This paper evaluates the intervention’s acceptability and pre-post changes in health outcomes. METHODS YLWH participated in ~25-person interactive WhatsApp groups facilitated by study staff for 6 months. Study staff sent groups weekly structured messages and encouraged unstructured messaging. We conducted a single-arm pilot among 55 YLWH ages 14-24 recruited from a government healthcare facility serving a mixed income area of Nairobi, Kenya. At enrollment and follow-up, self-report questionnaires assessed acceptability, ART information, motivation, and behavioral skills (IMB), depression, social support, stigma, resilience, and ART adherence. All participants received the intervention. We used generalized estimating equations (GEE) clustered by participant to evaluate changes in scores from baseline to follow-up and levels and correlates of participant WhatsApp messaging. RESULTS Median age was 18 and 67% were female. Intervention acceptability was high: all participants reported it was helpful, and 73% sent ≥1 WhatsApp message. Messaging levels were higher during school holidays, earlier in the intervention, and among youth age ≥18. IMB scores increased from enrollment to follow-up (66.9% to 71.3%, p<0.001). Stigma scores also increased (8.3% to 16.7%, p=0.001) and resilience scores decreased (75.0% to 70.0%, p<0.001). We found no significant change in ART adherence, social support, or depression. CONCLUSIONS Increased IMB scores following WhatsApp group participation may improve HIV outcomes. Increased stigma and decreased resilience may reflect transient unintended consequences of group sharing of challenging experiences, which should be addressed in larger randomized evaluations. WhatsApp groups present a promising and acceptable modality to deliver supportive interventions to YLWH beyond the clinic. CLINICALTRIAL This study was registered at clinicaltrials.gov (NCT05634265).

Background Intimate partner violence (IPV) is a major public health problem and is the most common form of violence against women. Women with HIV in serodifferent relationships may be at an increased risk of IPV compared to women without HIV, hindering their ability to adhere to antiretroviral therapy, clinic appointments, and condom use during sex. This study assessed the prevalence and correlates of IPV in the past year among women with HIV in serodifferent relationships in Nairobi, Kenya. Methods This cross-sectional study included women with HIV in serodifferent relationships who were at least 18 years old and provided written informed consent. Their experience of physical, sexual, or emotional violence in the past year by the current partner was assessed using 13 questions adapted from the World Health Organization survey on violence against women. Standardized instruments were used to assess sociodemographic and behavioral factors. Associations between intimate partner violence and other variables were evaluated using log binomial regression models. Results Of the 159 women enrolled, 47 (29.6%, 95% CI 22.9–37.2%) reported IPV in the past year. Of these, 32 (68.1%) reported emotional, 27 (57.4%) physical, and 27 (57.4%) sexual violence. In the multivariate model, pregnancy (adjusted prevalence ratio [aPR] 2.14, 95% CI 1.09–4.20), alcohol use (minimal drinking aPR 1.91, 95% CI 1.10–3.33; moderate/severe drinking aPR 1.17, 95% CI 0.53–2.59), male partner controlling behavior (aPR 2.09, 95% CI 1.24–3.51), and past physical violence (aPR 1.93, 95% CI 1.22–3.05) remained significantly associated with a higher prevalence of IPV in the past year. Conclusion This study identified a high prevalence of IPV in the past year among women with HIV in serodifferent relationships. Pregnant women and women who had experienced prior violence had a higher prevalence of IPV. These data highlight the need to screen for IPV during clinic visits, and to offer evidence based interventions to support women in serodifferent relationships who have experienced IPV.
