“I had made the decision, and no one was going to stop me” —facilitators of PREP adherence during pregnancy and postpartum in Cape Town, South Africa
PrEP is safe and effective but requires adherence during potential HIV exposure, yet the facilitators of long-term maternal adherence are not well understood. We conducted semi-structured interviews with 25 postpartum women who reported high adherence (PrEP use ≥ 25 days in last 30-days and never missed a PrEP prescription in pregnancy/postpartum period) within a PrEP service for pregnant and postpartum women. A thematic approach guided an iterative process of coding and analysis. Themes identified as drivers of optimal PrEP use were HIV risk perception, mainly because of partner’s behaviors and unknown serostatus, and a strong desire to have a baby free of HIV. Reported disclosure of PrEP use facilitated PrEP adherence. Women discussed having partner and family support, which included reminders to take PrEP daily. Primary barriers were anticipated or experienced stigma, overcome through education of partners and family about PrEP. Pregnant women experienced transient side-effects, but found ways to continue, including taking PrEP at night. PrEP programs for pregnant and postpartum women should integrate strategies to assist women with realistic appraisals of risk and teach skills for disclosure and securing support from significant others.N/

Experiences of HIV-positive postpartum women and health workers involved with community-based antiretroviral therapy adherence clubs in Cape Town, South Africa
Background
The rollout of universal, lifelong treatment for all HIV-positive pregnant and breastfeeding women (“Option B+”) has rapidly increased the number of women initiating antiretroviral treatment (ART) and requiring ART care postpartum. In a pilot project in South Africa, eligible postpartum women were offered the choice of referral to the standard of care, a local primary health care clinic, or a community-based model of differentiated ART services, the adherence club (AC). ACs have typically enrolled only non-pregnant and non-postpartum adults; postpartum women had not previously been referred directly from antenatal care. There is little evidence regarding postpartum women’s preferences for and experiences of differentiated models of care, or the capacity of this particular model to cater to their specific needs. This qualitative paper reports on feedback from both postpartum women and health workers who care for them on their respective experiences of the AC.
Methods
One-on-one in-depth qualitative interviews were conducted with 19 (23%) of the 84 postpartum women who selected the AC and were retained at approximately 12Â months postpartum, and 9 health workers who staff the AC. Data were transcribed and thematically analysed using NVivo 11.
Results
Postpartum women’s inclusion in the AC was acceptable for both participants and health workers. Health workers were welcoming of postpartum women but expressed concerns about prospects for longer term adherence and retention, and raised logistical issues they felt might compromise trust with AC members in general.
Conclusions
Enrolling postpartum women in mixed groups with the general adult population is feasible and acceptable. Preliminary recommendations are offered and may assist in supporting the specific needs of postpartum women transitioning from antenatal ART care.

Re-recruiting postpartum women living with HIV into a follow-up study in Cape Town, South Africa
Objective
Recruitment and retention present major challenges to longitudinal research in maternal and child health, yet there are few insights into optimal strategies that can be employed in low-resource settings. Following prior participation in a longitudinal study following women living with HIV through pregnancy and breastfeeding in Cape Town, women were re-contacted at least 18Â months after the last study contact and were invited to attend an additional follow-up visit. We describe lessons learnt and offer recommendations for a multiphase recruitment approach.
Results
Using telephone calls, home visits, clinic tracing and Facebook/WhatsApp messages, we located 387 of the 463 eligible women and successfully enrolled 353 (91% of those contacted). Phone calls were the most successful strategy, yielding 67% of enrolments. Over half of the women had changed their contact information since participation in the previous study. We recommend that researchers collect multiple contact details and use several recruitment strategies in parallel from the start of a study. Participants in longitudinal studies may require frequent contact to update contact information, particularly in settings where mobility is common

Experiences and perceptions of participants and staff involved in HIV research in Gugulethu, South Africa
It is important to understand the experiences and perceptions of HIV research from the perspectives of persons who have either participated in or worked on HIV research in lowresource settings. Obtaining such information is important because research in low-resource settings presents several ethical challenges that result in the vulnerability of participants due to factors such as low literacy levels, high rates of food insecurity and unemployment. Conducting research on the aforementioned can help researchers to design studies that mitigate some of the ethical challenges associated with conducting HIV research in lowresource communities. This dissertation adds on to existing literature on the experiences and perceptions of HIV research participants and staff involved in HIV research in low-resource settings. This dissertation is divided into three parts. Part A (Research protocol) discusses the importance of evaluating research participants’ experiences and perceptions of HIV studies conducted in lowresource settings. The section also outlines the purpose of the study, research questions, methodology, ethical considerations, rigour, reimbursement and dissemination of results. Part B (Literature review) presents an overview of the literature on HIV research in low-resource settings, with a specific focus on: ethical challenges, factors that contribute to participants’ decisions to participate in HIV research and findings from other studies which examined experiences and perceptions of HIV research in low-resource settings. The section also identifies gaps in the existing literature. Part C (Journal article) presents the findings of the study and the implications thereof
Sexual risk during pregnancy and postpartum periods among HIV-infected and -uninfected South African women: Implications for primary and secondary HIV prevention interventions.
HIV acquisition in pregnancy and breastfeeding contributes significantly toward pediatric HIV infection. However, little is known about how sexual behavior changes during pregnancy and postpartum periods which will help develop targeted HIV prevention and transmission interventions, including pre-exposure prophylaxis (PrEP).Cross-sectional study in HIV-infected and uninfected pregnant and postpartum women in Cape Town, South Africa. Interviewers collected survey data on demographic, sexual behaviors, and alcohol use among pregnant and post-partum women. We report descriptive results of sexual behavior by trimester and postpartum period, and results of multivariable logistic regression stratified by pregnancy status.We enrolled 377 pregnant and postpartum women (56% pregnant, 40% HIV-infected). During pregnancy, 98% of women reported vaginal sex (8% anal sex, 44% oral sex) vs. 35% and 88% during the periods 0-6 and 7-12 months postpartum, respectively (p1 partner in the past 12-months compared to postpartum women (18% vs. 13%, respectively, p6-months postpartum (13 mean sex acts in first trimester; 17 mean sex acts >6-months postpartum). Pregnant women had increased odds of reporting condomless sex at last sex (aOR = 2.96;95%CI = 1.84-4.78) and ever having condomless sex in past 3-months (aOR = 2.65;95%CI = 1.30-5.44) adjusting for age, HIV status, and sex frequency compared to postpartum women.We identified that sexual behaviors and risk behaviors were high and changing during pregnancy and postpartum periods, presenting challenges to primary and secondary HIV prevention efforts, including PrEP delivery to pregnant and breastfeeding women

Modelling the potential impact of providing preexposure prophylaxis in pregnant and breastfeeding women in South Africa.
ObjectiveHIV-uninfected pregnant and breastfeeding women are at high risk of HIV acquisition, contributing to vertical transmission of HIV. Preexposure prophylaxis (PrEP) is safe in pregnancy, but PrEP in pregnancy is not policy in many countries including South Africa. We evaluated the potential impact of providing PrEP for pregnant/breastfeeding women using a HIV model for South Africa.MethodsOur model considers two scenarios: a conservative scenario that matches the experience reported in the Kenyan PrEP programme for pregnant women (probability of uptake = 32% and 11% in high-risk and low-risk women, respectively); and an optimistic scenario with PrEP initiated by 80% of all pregnant women. We compared this with PrEP for female sex workers, MSM and adolescent girls/young women. Women are assumed to remain on PrEP throughout pregnancy and breastfeeding, and an equivalent average PrEP duration (2 years) is assumed in other scenarios.ResultsBetween 2020 and 2030, if PrEP is provided to pregnant/breastfeeding mothers, we project a 2.5% reduction in total HIV transmission [95% credibility interval (CI): 2.4-2.6%] in the conservative scenario and 7.2% (95% CI: 6.8-7.5%) in the optimistic scenario, which is similar to that in the female sex worker and MSM PrEP scenarios (1.9% and 3.0%, respectively). Without PrEP, 76 000 (95% CI: 64 000-90 000) new cases of vertical transmission are expected; PrEP provision may reduce these infections by 13% (95% CI: 13-14%) in the conservative scenario and 41% (95% CI: 39-44%) in the optimistic scenario.ConclusionHigh levels of uptake of and adherence to PrEP among pregnant/breastfeeding women could substantially reduce maternal and infant HIV acquisition in South Africa
Impact of adverse childhood experiences on women’s psychosocial and HIV-related outcomes and early child development in their offspring
Adverse childhood experiences (ACEs) may have a critical influence on adult outcomes and subsequent offspring development, but few data have explored the effects of ACEs in low-resource settings where the burdens of childhood adversity and HIV are high. Among mothers living with HIV in Cape Town, we examined the effects of ACEs on maternal psychosocial and HIV-related outcomes, as well as early child development in their offspring aged 36–60 months. The World Health Organization’s Adverse Childhood Experiences International Questionnaire was used to measure maternal reports of ACEs, and the Ages & Stages Questionnaire to screen for developmental delays in their offspring. Among 353 women (median age: 32 years), 84% reported ≥1 ACEs. Increased report of ACEs was strongly associated with depressive symptoms, hazardous alcohol use, intimate partner violence and self-reported suboptimal adherence to antiretroviral therapy. These associations were driven by more severe childhood experiences, including abuse, neglect and exposure to collective violence. Among 255 women who reported on their child’s development, maternal ACEs were associated with poorer socioemotional development. These data suggest that childhood adversity has long-term effects on maternal outcomes as well as their children’s socioemotional development and point to ACEs that might be targeted for screening and intervention
