Item Built Environment and HIV Linkage to Care in Rural South Africa(2023-01) Nosipho Shangase; Brian Pence; Sheri A. Lippman; Mi-Suk Kang Dufour; Chodziwadziwa Whiteson Kabudula; F. Xavier Gomez-Olive; Kathleen Kahn; Audrey PettiforBackground: We assessed built environment (residential density, landuse mix and aesthetics) and HIV linkage to care (LTC) among 1,681 (18–49 years-old) residents of 15 Mpumalanga villages, South Africa. Methods: Multilevel models (linear-binomial) were used for the association between built environment, measured using NEWS for Africa, and LTC from a clinical database of 9 facilities (2015–2018). Additionally, we assessed effect-measure modification by universal test-and-treat policy (UTT). Results: We observed, a significant association in the adjusted 3-month probability of LTC for residential density (risk difference (RD)%: 5.6, 95%CI: 1.2–10.1), however, no association for land-use mix (RD%: 2.4, 95%CI: 0.4, 5.2) and aesthetics (RD%: 1.2, 95% CI: 4.5–2.2). Among those diagnosed after UTT, residents of high land-use villages were more likely to link-to-care than those of low land-use villages at 12 months (RD%: 4.6, 95%CI: 1.1–8.1, p < 0.04), however, not at 3 months (RD%: 3.0, 95%CI: 2.1–8.0, p > 0.10). Conclusion: Findings suggest, better built environment conditions (adequate infrastructure, proximity to services etc.) help facilitate LTC. Moreover, UTT appears to have a protective effect on LTC.Item Effect of quality of caregiver-adolescent relationship on sexual debut, transactional sex and on age-disparate relationships among young women in rural South Africa enrolled in HPTN 068(2022-04-01) Nosipho Shangase; Jess Edwards; Brian Pence; Allison Aiello; Andrea Hussong; Xavier Gómez-Olivé; Kathleen Kahn; Marie Stoner; Audrey PettiforBackground: Adolescent girls and young women (AGYW) remain burdened by the HIV epidemic. Positive caregiver-child relationships are associated with safe sexual behaviors in young people; yet, this literature often highlights the role of parent-child communication and parental monitoring, neglecting the importance of emotional relationships between a caregiver and adolescent. Setting: We used longitudinal data from HIV Prevention Trial Network 068-conducted among 2533 AGYW (13-20 years) over a period of 5 years in Agincourt, South Africa. Method: Kaplan-Meier and Cox models were used to estimate the effect of quality of caregiver-adolescent relationships (caring and closeness) on sexual debut, and log-binomial models with generalized estimating equations were used to examine the relationship between our exposures and transactional sex and age-disparate relationships. Results: Sexual debut was delayed among those who reported high levels of caregiver caring [hazard ratio: 0.80, 95% confidence interval (CI): 0.69 to 0.93] and caregiver closeness (hazard ratio: 0.80, 95% CI: 0.68 to 0.95). AGYW who reported high quality caregiver-adolescent relationships had a lower risk of transactional sex [caring: risk ratio (RR): 0.67, 95% CI: 0.58 to 0.78; closeness: RR: 0.58; 95% CI: 0.50 to 0.67]. Similarly, those with high-quality caregiver-adolescent relationships were less likely to be in an age-disparate relationship (caring: RR: 0.68, 95% CI: 0.58 to 0.79; closeness: RR: 0.77, 95% CI: 0.66 to 0.90). Conclusions: Findings indicate high-quality caregiver-adolescent relationships are associated with delayed sexual debut, a lower risk of transactional sex, and having an older partner. Family-centered interventions are needed to improve relationships between AGYW and caregivers.
