RESUMEN
This prospective cohort study investigated the mobility patterns of 200 pregnant and postpartum women living with HIV in South Africa. Participants were enrolled during their third trimester from routine antenatal care near Cape Town, South Africa, and followed for six months postpartum. Quantitative data were collected at enrollment and follow-up. Mobility (self-reported) was common among the participants, despite the brief study period and the concurrent COVID-19 pandemic. While most reported stability in their current residence, 71% had a second main residence, primarily in the Eastern Cape (EC). Participants had a median of two lifetime moves, motivated by work, education, and family life. During the study period, 20% of participants met the study definition of travel (>7 days and >50â km), with trips predominantly to the EC, lasting a median duration of 30 days. Over one-third of participants with other living children reported that these children lived apart from them, with the mother's family being primary caregivers. These findings emphasize the need for targeted interventions to support continuity of care for mobile populations, particularly peripartum women living with HIV. The study contributes valuable insights into mobility dynamics and highlights unique barriers faced by this population, contributing to improved HIV care in resource-limited settings.

INTRODUCTION: Several HIV-related syndemics have been described among adults. We investigated syndemic vulnerability to hazardous drinking (HD), intimate partner violence (IPV) and household food insecurity (HFIS) in breastfed children born without HIV in urban South Africa. We compared those who were perinatally HIV exposed (CHEU) to those who were not (CHU), under conditions of universal maternal antiretroviral therapy (ART) and breastfeeding. METHODS: A prospective cohort of pregnant women living with HIV (WLHIV), and without HIV, were enrolled and followed with their infants for 12 months postpartum (2013-2017). All WLHIV initiated antenatal efavirenz-based ART. Measurements of growth (â¼3 monthly), infectious cause hospitalisation, ambulatory childhood illness (2-week recall) and neurodevelopment (BSID-III, measured at â¼12 months' age) were compared across bio-social strata using generalised linear regression models, with interaction terms; maternal data included interview-based measures for HD (AUDIT-C), IPV (WHO VAW) and HFIS. RESULTS: Among 872 breastfeeding mother-infant pairs (n = 461 CHEU, n = 411 CHU), WLHIV (vs. HIV negative) reported more unemployment (279/461, 60% vs. 217/411, 53%; p = 0.02), incomplete secondary education (347/461, 75% vs. 227/411, 55%; p < 0.0001), HD (25%, 117/459 vs. 7%, 30/411; p < 0.0001) and IPV (22%, 101/457 vs. 8%, 32/411; p < 0.0001) at enrolment; and HFIS at 12 months (45%, 172/386 vs. 30%, 105/352; p > 0.0001). There were positive interactions between maternal HIV and other characteristics. Compared to food secure CHU, the mean difference (95% CI) in weight-for-age Z-score (WAZ) was 0.06 (-0.14; 0.25) for food insecure CHU; -0.26 (-0.42; -0.10) for food secure CHEU; and -0.43 (-0.61; -0.25), for food insecure CHEU. Results were similar for underweight (WAZ < -2), infectious-cause hospitalisation, cognitive and motor delay. HIV-IPV interactions were evident for ambulatory diarrhoea and motor delay. There were HIV-HD interactions for odds of underweight, stunting, cognitive and motor delay. Compared to HD-unexposed CHU, the odds ratios (95% CI) of underweight were 2.31 (1.11; 4.82) for HD-exposed CHU; 3.57 (0.84; 15.13) for HD-unexposed CHEU and 6.01 (2.22; 16.22) for HD-exposed CHEU. CONCLUSIONS: These data suggest that maternal HIV-related syndemics may partly drive excess CHEU health risks, highlighting an urgent need for holistic maternal and family care and support alongside ART to optimise the health of CHEU.

BACKGROUND: Mobile health (mHealth) initiatives are increasingly common in low-resource settings, but the appropriateness of smartphone interventions in health care settings is uncertain. More research is needed to establish the appropriateness and feasibility of integrating new mHealth modalities (novel apps and social media apps) in the South African context. OBJECTIVE: In this study, to inform future mHealth interventions, we describe smartphone ownership, preferences, and usage patterns among pregnant women living with HIV in Gugulethu, South Africa. METHODS: We screened pregnant women living with HIV from December 2019 to February 2021 for the CareConekta trial. To be enrolled in the trial, respondents were required to be 18 years of age or older, living with HIV, ≥28 weeks pregnant, and own a smartphone that met the technical requirements of the CareConekta app. In this secondary analysis, we describe mobile phone ownership and sociodemographic characteristics of all women screened for eligibility (n=639), and smartphone use patterns among those enrolled in the trial (n=193). RESULTS: Overall, median age was 31 (IQR 27-35) years. Of the 582 women who owned smartphones, 580 responded to the question about whether or not it was a smartphone, 2 did not. Among those with smartphones, 92% (421/458) of them used the Android operating system of version 5.0 or above, 98% (497/506) of phones had a GPS, and 96% (485/506) of individuals charged their phones less than twice a day. Among women who were enrolled in the trial, nearly all (99%, 190/193) owned the smartphone themselves; however, 14% (26/193) shared their smartphone with someone. In this case, 96% (25/26) reported possessing the phone most of the day. Median duration of ownership of the smartphone was 12 (IQR 5-24) months, median duration with current phone number use was 25 (IQR 12-60) months, and median number of cell phone numbers owned 2 years prior to enrollment in the trial was 2 (IQR 1-2). Receiving (192/193, 99.5%) and making (190/193, 99%) phone calls were among the most common smartphone uses. The least used features were GPS (106/193, 55%) and email (91/193, 47%). WhatsApp was most frequently reported as a favorite app (181/193, 94%). CONCLUSIONS: Smartphone ownership is very common among pregnant women living with HIV in this low-resource, periurban setting. Phone sharing was uncommon, nearly all used the Android system, and phones retained sufficient battery life. These results are encouraging to the development of mHealth interventions. Existing messaging platforms-particularly WhatsApp-are exceedingly popular and could be leveraged for interventions. Findings of moderate smartphone ownership turnover and phone number turnover are considerations for mHealth interventions in similar settings.

RESUMEN
BACKGROUND: Mobile health interventions are common in public health settings in Africa, and our preliminary work showed that smartphones are increasing in South Africa. We developed a novel smartphone app-CareConekta-that used GPS location data to characterize personal mobility to improve engagement in HIV care among pregnant and postpartum women living with HIV in South Africa. The app also used the user's location to map nearby clinics. OBJECTIVE: We aimed to describe the feasibility, acceptability, and initial efficacy of using the app in a real-world setting. METHODS: We conducted a prospective randomized controlled trial at a public sector clinic near Cape Town, South Africa. We enrolled 200 pregnant (third trimester) women living with HIV who owned a smartphone that met the required specifications. All participants installed the app, designed to collect 2 GPS heartbeats per day to geolocate the participant within a random 1-km fuzzy radius (for privacy). We randomized (1:1) participants to a control arm to receive the app with no additional support or an intervention arm to receive supportive phone calls, WhatsApp (Meta Platforms, Inc) messages, or both from the study team when traveling >50 km from the study area for >7 days. In addition to mobility data collected daily through the phone, participants completed questionnaires at enrollment and follow-up (approximately 6 months post partum). RESULTS: A total of 7 participants were withdrawn at enrollment or shortly after because of app installation failure (6/200, 3%) or changing to an unsuitable phone (1/200, 0.50%). During the study period, no participant's smartphone recorded at least 1 heartbeat per day, which was our primary feasibility measure. Of the 171 participants who completed follow-up, only half (91/171, 53.2%) reported using the same phone as that used at enrollment, with the CareConekta app still installed on the phone and GPS usually enabled. The top reasons reported for the lack of heartbeat data were not having mobile data, uninstalling the app, and no longer having a smartphone. Acceptability measures were positive, but participants at follow-up demonstrated a lack of understanding of the app's purpose and function. The clinic finder was a popular feature. Owing to the lack of consistent GPS heartbeats throughout the study, we were unable to assess the efficacy of the intervention. CONCLUSIONS: Several key challenges impeded our study feasibility. Although the app was designed to reverse bill participants for any data use, the lack of mobile data was a substantial barrier to our study success. Participants reported purchasing WhatsApp data, which could not support the app. Problems with the web-based dashboard meant that we could not consistently monitor mobility. Our study provides important lessons about implementing an ambitious GPS-based study under real-world conditions in a limited-resource setting.

BACKGROUND: We investigated the association between travel and viraemia in post-partum women with human immunodeficiency virus on antiretroviral therapy (ART). METHODS: Data are from a trial of post-partum ART delivery strategies. Women who initiated ART during pregnancy, were clinically stable with a viral load (VL) <400 copies/ml and were <10 weeks post-partum were enrolled at a primary care antenatal clinic in Cape Town, South Africa. Study visits at 3, 6, 12, 18 and 24 months post-partum included questions about travel, defined as ≥1 night spent outside of the city, and VL testing. Generalised mixed effects models assessed the association between travel and subsequent VL ≥400 copies/ml. RESULTS: Among 402 women (mean age 29 y, 35% born in the Western Cape), 69% reported one or more travel events over 24 months. Being born beyond the Western Cape (adjusted odds ratio [aOR] 2.03 [95% confidence interval {CI} 1.49 to 2.77]), duration post-partum in months (aOR 1.03 [95% CI 1.02 to 1.05]) and living with the child (aOR 0.60 [95% CI 0.38 to 0.93]) were associated with travel. In multivariable analyses, a travel event was associated with a 92% increase in the odds of a VL ≥400 copies/ml (aOR 1.92 [95% CI 1.19 to 3.10]). CONCLUSIONS: Interventions to support women on ART who travel are urgently required.

PURPOSE: Pregnant and postpartum women living with HIV in South Africa are at high risk of dropping out of care, particularly after delivery. Population mobility may contribute to disruptions in HIV care, and postpartum women are known to be especially mobile. To improve engagement in HIV care during the peripartum period, we developed CareConekta, a smartphone application (app) that uses GPS coordinates to characterise mobility and allow for real-time intervention. We conducted a randomised controlled pilot study to assess feasibility, acceptability and initial efficacy of the app intervention to improve engagement in HIV care. This cohort profile describes participant enrolment and follow-up, describes the data collected and provides participant characteristics. PARTICIPANTS: We enrolled 200 pregnant women living with HIV attending routine antenatal care at the Gugulethu Midwife Obstetric Unit in Cape Town, South Africa. Eligible women must have owned smartphones that met the app's technical requirements. Seven participants were withdrawn near enrolment, leaving 193 in the cohort. FINDINGS TO DATE: Data were collected from detailed participant questionnaires at enrolment and follow-up (6 months after delivery), as well as GPS data from the app, and medical records. Follow-up is complete; initial analyses have explored smartphone ownership, preferences and patterns of use among women screened for eligibility and those enrolled in the study. FUTURE PLANS: Additional planned analyses will characterise mobility in the population using the phone GPS data and participant self-reported data. We will assess the impact of mobility on engagement in care for the mother and infant. We also will describe the acceptability and feasibility of the study, including operational lessons learnt. By linking this cohort to the National Health Laboratory Service National HIV Cohort in South Africa, we will continue to assess engagement in care and mobility outcomes for years to come. Collaborations are welcome. TRIAL REGISTRATION NUMBER: NCT03836625.

Background: Detection of antiretrovirals (ARVs) in biological specimens is a reliable, objective way to measure adherence. However, routine ARV testing is not feasible in many high-burden settings. This study explored if pharmacy data could accurately predict HIV viremia postpartum in previously virally suppressed women. Methods: South African women with HIV who initiated antiretroviral therapy (ART) during pregnancy and achieved viral suppression (VS; viral load [VL]≤50â copies/mL) were followed postpartum; during follow-up, plasma VL was measured and ARV adherence self-reported. A portion of samples were tested for the presence of ARV using mass spectrometry. Patient-level routine pharmacy data were used to classify if women should have the drug in hand for the past 7 days before the visit date. Logistic regressions were used to calculate associations between adherence and viral nonsuppression (VNS; VL > 50) or failure (VF; VL > 1000) at the first study visit of women who had ARV measured. Data for all women were examined for associations of self-reported adherence and drug in hand with VS and VF at 2, 6, and 12 months postpartum. Results: Women with no ARV detected were significantly more likely to have VNS (odds ratio [OR], 26.4). Having no drug in hand for 7 days was also predictive of VNS in these same women (OR, 7.0) and the full cohort (n = 572) at 3 (OR, 2.9), 6 (OR, 8.7), and 12 months (OR, 14.5). Similar results were seen for VF. Conclusions: These data show that routine pharmacy data can act as a highly predictive mechanism for identifying patients at risk of VNS and VF due to nonadherence.
RESUMEN
BACKGROUND: Patients stable on antiretroviral therapy (ART) may require transfer between health care facilities to maintain continuous care, yet data on the frequency, predictors, and virologic outcomes of transfers are limited. METHODS: Data for all viral load (VL) testing at public sector health facilities in the Western Cape Province (2011-2018) were obtained. Participant inclusion criteria were a first VL between 2011 and 2013, age >15 years at ART initiation, and >1 VL within 5 years of ART initiation, of which ≥1 was at a primary health care facility. Two successive VLs taken at different facilities indicated a transfer. We assessed predictors of transfer using generalized estimating equations with Poisson regression and the association between transfer and subsequent VL> 1000 copies/mL using generalized mixed effects. RESULTS: Overall 84,814 participants (median age at ART initiation 34 years and 68% female) were followed up for up to 4.5 years after their first VL: 34% (n = 29,056) transferred at least once, and among these, 26% transferred twice and 11% transferred thrice or more. Female sex, age <30 years, and first VL > 1000 copies/mL were independently associated with an increased rate of transfer [adjusted rate ratio 1.24, 95% confidence interval (CI): 1.21 to 1.26; 1.34, 95% CI: 1.31 to 1.36; and 1.42, 95% CI: 1.38 to 1.45, respectively]. Adjusting for age, sex, and disengagement, transfer was associated with an increased relative odds of VL > 1000 copies/mL (odds ratio 1.35, 95% CI: 1.29 to 1.42). CONCLUSIONS: Approximately one-third of participants transferred and virologic outcomes were poor post-transfer. Stable patients who transfer may require additional support to maintain adherence.

BACKGROUND: There are few data on the utility of tenofovir diphosphate (TFV-DP) in dried blood spots (DBSs) to predict future viral load (VL) in postpartum women with HIV on antiretroviral therapy (ART). METHODS: We conducted a nested case-control study within a trial of postpartum ART delivery strategies. Participants started ART containing tenofovir disoproxil fumarate (TDF) in pregnancy, were <10 weeks postpartum, and had a VL <400 copies/mL. VL and TFV-DP samples were taken every 3-6 months over 24 months. Cases had ≥1 VL ≥20 copies/mL; controls were randomly sampled from women with persistent viral suppression (VS; VL <20 copies/mL). Generalized estimating equations were used to calculate likelihood odds ratios (LORs) for future VL ≥20 copies/mL by TFV-DP concentration at the preceding visit. RESULTS: 61 cases and 20 controls contributed 365 DBS-VL pairs (median ART duration, 16 months). Sensitivity and specificity of TFV-DP <700 fmol/punch to detect future viremia were 62.9% (95% CI, 54.7-70.6%) and 89.7% (84.9-93.4%), respectively. Adjusting for age, ART duration, previous VL, and duration between the TFV-DP and VL measures, LORs of viremia for TFV-DP concentrations 350-699 and <350 fmol/punch versus TFV-DP ≥1850 fmol/punch were 3.5 (95% CI, 1.1-10.8; Pâ =â .033) and 12.9 (3.6-46.6; Pâ <â .0001), respectively. Including only samples taken during VS, the LOR of future viremia for TFV-DP concentration <350 fmol/punch versus TFV-DP ≥1850 fmol/punch was 9.5 (1.9-47.0). CONCLUSIONS: TFV-DP concentrations in DBSs were strongly associated with future viremia and appear useful to identify nonadherence and predict future elevated VL.

In settings with a high burden of HIV, pregnant women often experience a cluster of risk factors, including alcohol use and intimate partner violence (IPV). These interrelated risks are poorly understood among pregnant women at risk of HIV in sub-Saharan Africa. We aim to determine cross-sectional associations between pregnant women's alcohol use and victimization due to IPV in the HIV-Unexposed-Uninfected Mother-Infant Cohort Study in Cape Town, South Africa. Women who tested HIV-negative at first antenatal care (ANC) visit were followed to delivery. Trained interviewers collected demographic and psychosocial information, including recent alcohol use and experiences of IPV victimization. We assess the prevalence of alcohol use and associations with IPV using multivariable logistic regression. In 406 HIV-uninfected pregnant women (mean age = 28 years; mean gestational age = 21 weeks), 41 (10%) reported alcohol consumption in the past 12 months; 30/41 (73%) of these at hazardous levels. Any and hazardous alcohol use were associated with greater odds of reporting past year IPV (adjusted odds ratio [aOR] for hazardous use: 3.24, 95% CI = 1.11, 7.56; aOR for any alcohol use: 2.97, 95% CI = 1.19, 7.45). These data suggest the occurrence of overlapping HIV risk factors among pregnant women and may help design improved health interventions in this population.

BACKGROUND: Maternal HIV and antiretroviral therapy (ART) exposure in utero may influence infant weight, but the contribution of maternal y body mass index (BMI) to early life overweight and obesity is not clear. OBJECTIVE: To estimate associations between maternal BMI at entry to antenatal care (ANC) and infant weight through approximately 1 year of age and to evaluate whether associations were modified by maternal HIV status, maternal HIV and viral load, breastfeeding intensity through 6 months or timing of entry into ANC. METHODS: We followed HIV-uninfected and -infected pregnant women initiating efavirenz-based ART from first antenatal visit through 12 months postpartum. Infant weight was assessed via World Health Organization BMI and weight-for-length z-scores (WLZ) at 6 weeks, 3, 6, 9 and 12 months. We used multivariable linear mixed-effects models to estimate associations between maternal BMI and infant z-scores over time. RESULTS: In 861 HIV-uninfected infants (454 HIV-exposed; 407 HIV-unexposed), nearly 20% of infants were overweight or obese by 12 months of age, regardless of HIV exposure status. In multivariable analyses, increasing maternal BMI category was positively associated with higher infant BMIZ and WLZ scores between 6 weeks and 12 months of age and did not differ by HIV exposure status. However, HIV-exposed infants had slightly lower BMIZ and WLZ trajectories through 12 months of age, compared with HIV-unexposed infants across all maternal BMI categories. Differences in BMIZ and WLZ scores by HIV exposure were not explained by timing of entry into ANC or maternal viral load pre-ART initiation, but z-scores were slightly higher for HIV-exposed infants who were predominantly or exclusively versus partially breastfed. CONCLUSIONS: These findings suggest maternal BMI influences early infant weight gain, regardless of infant HIV exposure status. Intervention to reduce maternal BMI may help to address growing concerns about obesity among HIV-uninfected children.

BACKGROUND: Perceived birth experiences of parents can have a lasting impact on children. We explored the birth and new parenting experiences of South African parents in 2020 during the Covid-19 lockdown. METHODS: We conducted a cross-sectional online survey with consenting parents of babies born in South Africa during 2020. Factors associated with negative birth emotions and probable depression were estimated using logistic regression. RESULTS: Most of the 520 respondents were females (n = 496, 95%) who gave birth at private hospitals (n = 426, 86%). Mothers reported having overall positive birth emotions (n = 399, 80%). Multivariable analysis showed that having a preterm baby (aOR 2.89; CI 1.51-5.53) and the mother self-reporting that Covid-19 affected her birth experience (aOR 4.25; CI 2.08-8.68) increased the odds of mothers reporting predominantly negative emotions about their birth. The mother having her preferred delivery method reduced the odds of having negative birth emotions (aOR 0.41; CI 0.25-0.66). Multivariable analysis showed that having predominantly negative emotions about the birth increased the odds of probable minor depression (aOR 3.60; CI 1.93-6.70). Being older reduced the odds of having probable minor depression (25-34 years aOR 0.36; CI 0.10-1.32; 35 years or older aOR 0.25; CI 0.06-0.91). CONCLUSIONS: Lockdown exacerbated many birth and parenting challenges including mental health and health care access. However, overall experiences were positive and there was a strong sense of resilience amongst parents.

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.

Transitions between services for continued antiretroviral treatment (ART) during and after pregnancy are a commonly overlooked aspect of the HIV care cascade, but ineffective transitions can lead to poor health outcomes for women and their children. In this qualitative study, we conducted interviews with 15 key stakeholders from Ministries of Health along with PEPFAR-supported and other in-country non-governmental organizations actively engaged in national programming for adult HIV care and prevention of mother-to-child-transmission of HIV (PMTCT) services in Côte d'Ivoire, Lesotho and Malawi. We aimed to understand perspectives regarding transitions into and out of PMTCT services for continued ART. Thematic analysis revealed that, although transitions of care are necessary and a potential point of loss from ART care in all three countries, there is a lack of clear guidance on transition approach and no formal way of monitoring transition between services. Several opportunities were identified to monitor and strengthen transitions of care for continued ART along the PMTCT cascade.

OBJECTIVE: We examined the longitudinal association between women's exposure to intimate partner violence (IPV) and HIV viral load during pregnancy and postpartum. DESIGN: Secondary analysis of an HIV-positive cohort enrolled during pregnancy at a South African antenatal clinic. METHODS: Viral load was assessed at 10 study visits and analyzed continuously as log10 copies/ml and suppression at less than 50âcopies/ml. IPV was measured at three timepoints using behaviorally specific items. We used multivariate logistic regression to examine the association between IPV and viral suppression, and cross-lagged dynamic panel modeling (DPMs) to estimate the longitudinal association between IPV (lagged by 3-6 months) and log10 viral load. RESULTS: Of 471 women, 84% were virally suppressed by 6 weeks postpartum and 67% at 12 months postpartum. One-third reported IPV exposure. IPV victimization was not associated with viral suppression at delivery, but was associated with a reduced odds of viral suppression at 12 months postpartum (aOR = 0.48, 95% CIâ=â0.27-0.85). Findings were robust to sensitivity analyses at different timepoints and clinical cut-points. In DPMs, lagged IPV exposure was associated with higher log10 viral load after controlling for past viral load, duration on ART, age, alcohol use, and gestation at study enrolment. Each standardized increase in IPV intensity was associated with higher log10 viral load (standardized coefficientâ=â0.12, 95% CIâ=â0.05-0.23). CONCLUSION: Although viral suppression was widely achieved during pregnancy, suppression rates declined postpartum in this South African cohort. These data suggest IPV is longitudinally associated with elevated viral load postpartum. Interventions for reducing exposure to IPV are important for the health of women and may improve HIV care and treatment.

BACKGROUND: Peripartum women living with HIV in South Africa are at high risk of dropping out of care and are also a particularly mobile population, which may impact their engagement in HIV care. With the rise in mobile phone use worldwide, there is an opportunity to use smartphones and GPS location software to characterize mobility in real time. OBJECTIVE: The aim of this study was to propose a smartphone app that could collect individual GPS locations to improve engagement in HIV care and to assess potential users' attitudes toward the proposed app. METHODS: We conducted 50 in-depth interviews (IDIs) with pregnant women living with HIV in Cape Town and Johannesburg, South Africa, and 6 focus group discussions (FGDs) with 27 postpartum women living with HIV in Cape Town. Through an open-ended question in the IDIs, we categorized "positive," "neutral," or "negative" reactions to the proposed app and identified key quotations. For the FGD data, we grouped the text into themes, then analyzed it for patterns, concepts, and associations and selected illustrative quotations. RESULTS: In the IDIs, the majority of participants (76%, 38/50) responded favorably to the proposed app. Favorable comments were related to the convenience of facilitated continued care, a sense of helpfulness on the part of the researchers and facilities, and the difficulties of trying to maintain care while traveling. Among the 4/50 participants (8%) who responded negatively, their comments were primarily related to the individual's responsibility for their own health care. The FGDs revealed four themes: facilitating connection to care, informed choice, disclosure (intentional or unintentional), and trust in researchers. CONCLUSIONS: Women living with HIV were overwhelmingly positive about the idea of a GPS-based smartphone app to improve engagement in HIV care. Participants reported that they would welcome a tool to facilitate connection to care when traveling and expressed trust in researchers and health care facilities. Within the context of the rapid increase of smartphone use in South Africa, these early results warrant further exploration and critical evaluation following real-world experience with the app.
RESUMEN
INTRODUCTION: Women living with HIV are required to transition into the prevention of mother-to-child transmission of HIV (PMTCT) services when they become pregnant and back to ART services after delivery. Transition can be a vulnerable time when many women are lost from HIV care yet there is little guidance on the optimal transition approaches to ensure continuity of care. We reviewed the available evidence on existing approaches to transitioning women into and out of PMTCT, outcomes following transition and factors influencing successful transition. METHODS: We searched PubMed and SCOPUS, as well as abstracts from international HIV-focused meetings, from January 2006 to July 2020. Studies were included that examined three points of transition: pregnant women already on ART into PMTCT (transition 1), pregnant women living with HIV not yet on ART into treatment services (transition 2) and postpartum women from PMTCT into general ART services after delivery (transition 3). Results were grouped and reported as descriptions of transition approach, comparison of outcomes following transition and factors influencing successful transition. RESULTS & DISCUSSION: Out of 1809 abstracts located, 36 studies (39 papers) were included in this review. Three studies included transition 1, 26 transition 2 and 17 transition 3. Approaches to transition were described in 26 studies and could be grouped into the provision of information at the point of transition (n = 8), strengthened communication or linkage of data between services (n = 4), use of transition navigators (n = 12), and combination approaches (n = 4). Few studies were designed to directly assess transition and only nine compared outcomes between transition approaches, with substantial heterogeneity in study design, setting and outcomes. Four themes were identified in 25 studies reporting on factors influencing successful transition: fear, knowledge and preparedness, clinic characteristics and the transition requirements and process. CONCLUSIONS: This review highlights that, despite the need for women to transition into and out of PMTCT services for continued ART in many settings, there is very limited evidence on optimal transition approaches. Ongoing operational research is required to identify sustainable and acceptable transition approaches and service delivery models that support continuity of HIV care during and after pregnancy.

OBJECTIVE: To examine associations between high blood pressure (BP) when entering antenatal care (ANC) and birth outcomes in a cohort of pregnant HIV- and women living with HIV (WLHIV) initiating antiretroviral treatment (ART). STUDY DESIGN: Prospective cohort study. MAIN OUTCOME MEASURES: Cesarean delivery, preterm birth (<37 weeks' gestation), low birthweight (LBW, <2500 g), small-for-gestational age (SGA, <10th percentile), and large-for-gestational age (LGA, >10th percentile for GA). RESULTS: Of 1116 women (median GA 20 weeks; WLHIV 53%), 48% (53% WLHIV; 43% HIV-) entered ANC with high BP, defined as elevated (120-129 or < 80 mmHg), stage 1 (>130-139 or 80-89) or stage 2 hypertension (≥140 / or ≥ 90). WLHIV were more likely to have high BP (RR 1.32; 95%CI 1.12-1.57), controlling for pre-pregnancy body mass index and additional confounders. In multivariable analysis, there was no evidence that high BP increased the risk of cesarean delivery (RR 1.10, 95% CI 0.92-1.30), preterm birth (RR 1.15, 95% CI 0.81-1.62), LBW (RR 1.16, 95% CI 0.84-1.60) or SGA (RR 1.02, 0.72-1.44), overall or when stratified by HIV-status. High BP was associated with an increased risk of LGA (RR 1.43; 95% CI 1.00-2.03). CONCLUSION: In this setting, half of women had high BP at entry into ANC, with WLHIV at increased risk of high BP. There was no strong evidence that high BP increased the risk of adverse birth outcomes overall, or by HIV-status, with the exception of LGA. WLHIV may be at high risk of high BP during pregnancy and should be monitored closely.

OBJECTIVES: Mother-child pairs may separate during early life, yet the health impacts thereof are unclear. We explored the patterns and impact of separation among women living with HIV (WLHIV) and their children in South Africa. METHODS: WLHIV who had initiated antiretroviral therapy (ART) during pregnancy received HIV viral load (VL) testing and completed a timeline questionnaire of mother-child separation since delivery at 3-5 years post-partum. Health care usage was abstracted from routine medical records. We examined associations between separation and (a) maternal health outcomes (engagement in HIV care and HIV viral suppression, [VS]) and (b) child health outcomes (post-breastfeeding HIV testing and immunisation completion), using logistic regression. RESULTS: Of 346 mother-child pairs (median maternal age at antenatal ART initiation, 28 years), 24% were ever separated (median time to first separation 20 months, interquartile range [IQR] 9, 31). Most separated children were living with their grandmothers (65/83, 78%). Mothers who ever separated were younger, and more likely to be employed, and to reside in informal housing than those who never separated. Any separation reduced the odds of VS ≤ 50 copies/mL at four years post-partum (odds ratio 0.57; 95% CI 0.34-0.93); associations were similar for VL ≤ 1000 copies/mL and maternal engagement in care. No association was found between separation and child confirmatory HIV testing or immunisation completion. CONCLUSIONS: In this setting, mother-child separation is common in the first four years of life and appears associated with suboptimal maternal outcomes. Further research is required to understand the drivers and implications of mother-child separation.
OBJECTIFS: Les couples mère-enfant peuvent être séparés au début de la vie, mais les effets sur la santé ne sont pas clairs. Nous avons exploré les modèles et l'impact de la séparation chez les femmes vivant avec le VIH (PVVIH) et leurs enfants en Afrique du Sud. MÉTHODES: Les PVVIH qui avaient initié un traitement antirétroviral (ART) pendant la grossesse ont subi un test de charge virale du VIH (CV) et ont rempli un questionnaire chronologique sur la séparation mère-enfant depuis l'accouchement à 3-5 ans post-partum. L'utilisation des soins de santé a été extraite des dossiers médicaux de routine. Nous avons examiné les associations entre la séparation et (a) les résultats pour la santé maternelle (engagement dans les soins du VIH et la suppression virale du VIH [SV]) et (b) les résultats pour la santé de l'enfant (dépistage du VIH après l'allaitement et achèvement de la vaccination), en utilisant la régression logistique. RÉSULTATS: Sur 346 couples mère-enfant (âge maternel médian au début de l'ART prénatal, 28 ans), 24% ont été séparés (délai médian jusqu'à la première séparation 20 mois, intervalle interquartile [IQR] 9 à 31). La plupart des enfants séparés vivaient avec leurs grands-mères (65/83, 78%). Les mères qui ont vécu une telle séparation étaient plus jeunes et plus susceptibles d'avoir un emploi et de vivre dans un logement informel que celles qui ne l'ont jamais vécue. Toute séparation réduisait les chances de SV ≤50 copies/mL à quatre ans après l'accouchement (odds ratio 0,57; IC95%: 0,34-0,93); les associations étaient similaires pour la CV ≤1000 copies/mL et l'engagement de la mère dans les soins. Aucune association n'a été trouvée entre la séparation et le test de confirmation du VIH chez l'enfant ou l'achèvement de la vaccination. CONCLUSIONS: Dans ce contexte, la séparation mère-enfant est courante au cours des quatre premières années de la vie et semble associée à des résultats maternels sous-optimaux. Des recherches supplémentaires sont nécessaires pour comprendre les facteurs et les implications de la séparation mère-enfant.
