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.

Background: Point-of-care (POC) nucleic acid testing for diagnosis of HIV in infants facilitates earlier initiation of antiretroviral therapy (ART) than with centralised (standard-of-care, SOC) testing, but can be more expensive. We evaluated cost-effectiveness data from mathematical models comparing POC with SOC to provide global policy guidance.

Methods: In this systematic review of modelling studies, we searched PubMed, MEDLINE, Embase, the National Health Service Economic Evaluation Database, Econlit, and conference abstracts, combining terms for "HIV" + "infant"/"early infant diagnosis" + "point-of-care" + "cost-effectiveness" + "mathematical models", without restrictions from database inception to July 15, 2022.

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.

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.

Background: South Africa faces dual epidemics of HIV and obesity; however, little research has explored whether HIV status influences associations between pre-pregnancy body mass index (BMI) and adverse birth outcomes.

Objectives: To examine associations between pre-pregnancy body mass index (BMI) and adverse birth outcomes, and if they differ by HIV status.

Methods: We followed HIV-uninfected and -infected pregnant women initiating antiretroviral therapy (ART) from first antenatal visit through delivery.

In South Africa, up to 40% of pregnant women are living with human immunodeficiency virus (HIV), and 30-45% are obese. However, little is known about the dual burden of HIV and obesity in the postpartum period. In a cohort of HIV-uninfected and HIV-infected pregnant women initiating antiretroviral therapy in Cape Town, South Africa, we examined maternal anthropometry (weight and body mass index [BMI]) from 6 weeks through 12 months postpartum.

Background: Without breastfeeding and maternal antiretroviral therapy (ART), HIV-exposed uninfected (HEU) infants have greater infectious morbidity than HIV-unexposed (HU) infants. We hypothesised that with the introduction of universal maternal ART, breastfed HEU and HU infants would have similar morbidity.

Methods: We prospectively studied a cohort of HIV-infected pregnant women initiating ART, and a parallel group of HIV-uninfected pregnant women, starting from their first antenatal care visit at the Gugulethu Midwife Obstetrics Unit in Cape Town, South Africa.

: Despite widespread concerns about HIV incidence in pregnant and postpartum women, there are few data from Africa on HIV acquisition in breastfeeding and subsequent mother-to-child transmission. We measured HIV incidence in a prospective cohort of 413 peripartum and breastfeeding women who tested HIV-negative during pregnancy. In 377 woman-years accrued postpartum (median duration of follow-up, 1 year), there were seven women infected after delivery (postpartum incidence, 1.

Background: Over 1 million HIV-exposed uninfected (HEU) children are born in sub-Saharan Africa annually. Little data exist on the risk of impaired growth in this population under current policies of universal maternal antiretroviral therapy (ART) with breastfeeding. We aimed to study the growth of breastfed HEU children born to women who initiated ART during pregnancy and compare their growth with that of breastfed HIV-unexposed (HU) children drawn from the same community.

Background: Elevated HIV viral load (VL) in pregnancy has been linked to increased risk of mortality, immunologic abnormalities, infectious morbidity and restricted growth among HIV-exposed uninfected (HEU) children, but little is known about effects on child development.

Methods: HIV-infected women initiating lifelong antiretroviral therapy (ART; tenofovir + emtricitabine + efavirenz) antenatally were followed from first antenatal visit through delivery and with their breastfed infants postpartum. Cognitive, motor and expressive language development (Bayley Scales of Infant and Toddler Development-Third Edition; delay defined as score <85) were assessed on a subset of HEU infants.

Background: Studies of antiretroviral therapy (ART) use during pregnancy in HIV-infected women have suggested that ART exposure may be associated with adverse birth outcomes. However, there are few data from sub-Saharan Africa where HIV is most common, and few studies involving the World Health Organization's (WHO's) recommended first-line regimens.

Methods: We enrolled consecutive HIV-infected pregnant women and a comparator cohort of uninfected women at a primary-level antenatal care facility in Cape Town, South Africa.

Objective: HIV-exposed but HIV-uninfected (HEU) children are widely considered at increased risk of mortality and morbidity. Recent advances in prevention of mother-to-child HIV transmission (PMTCT) strategies, incorporating life-long universal maternal antiretroviral therapy (ART, "Option B+") with extended breastfeeding, may improve HEU child health substantially. We critically reviewed reports of mortality/morbidity among HEU and HIV-unexposed (HU) children in sub-Saharan Africa.
