ABSTRACT
Children born to mothers living with HIV may experience greater risk of poor growth and development outcomes than their HIV-unexposed peers. Few studies have examined the relationship between maternal depression and social support with infant growth and development in the context of HIV. We conducted a prospective cohort study of 2,298 pregnant women living with HIV in Dar es Salaam, Tanzania, assessing antenatal depression (Hopkins Symptoms Checklist-25) and social support (Duke-UNC Functional Social Support Questionnaire) at 12-27 weeks of gestation. At one-year age, infant anthropometry and caregiver-reported infant development were assessed. Generalized estimating equations were used to assess mean differences (MD) and relative risks (RR) for growth and developmental outcomes. Symptoms consistent with maternal antenatal depression had 67% prevalence and were associated with infant wasting (RR 2.61; 95% confidence interval (CI) 1.03-6.65; z = 2.02; p = 0.04), but no other growth or developmental outcomes. Greater maternal social support was not associated with infant growth outcomes. Greater affective support was associated with better cognitive (MD 0.18; CI 0.01-0.35; z = 2.14; p = 0.03) and motor (MD 0.16; CI 0.01-0.31; z = 2.04; p = 0.04) development scores. Greater instrumental support was associated with better cognitive (MD 0.26; CI 0.10-0.42; z = 3.15; p < 0.01), motor (MD 0.17; CI 0.02-0.33; z = 2.22; p = 0.03), and overall (MD 0.19; CI 0.03-0.35; z = 2.35; p = 0.02) development scores. Depressive symptoms were associated with greater risk of wasting, while social support was associated with better infant development scores. Strategies to improve mental health and social support for mothers living with HIV during the antenatal period may benefit infant growth and development.
ABSTRACT
BACKGROUND: Women who experience antenatal depression may be at increased risk of adverse birth outcomes. Few studies have examined this association among women living with HIV (WHIV). METHODS: We conducted a prospective cohort study of 2298 pregnant WHIV on antiretroviral therapy (ART) in Dar es Salaam, Tanzania, who were participants in a randomized trial of vitamin D3 supplementation. Depressive symptoms were assessed at 12-27 weeks gestation using the Hopkins Symptoms Checklist (HSCL-25). Generalized estimating equations to account for twins were used to assess the relative risks of adverse birth outcomes. RESULTS: Approximately 67 % of the women in our study population reported symptoms consistent with depression. We observed a 4.0 % prevalence of stillbirth and a 25.1 % prevalence of preterm birth. We found that low social support, higher education, and more recent initiation of ART were associated with a greater risk of antenatal depression. There was no association of antenatal depression with risk of fetal loss, stillbirth, low birth weight, birth weight, preterm birth, gestational age at delivery, or small-for-gestational age. LIMITATIONS: Depression was self-reported and only collected at one timepoint in pregnancy. Our findings may not be generalizable to all WHIV. CONCLUSIONS: Our findings illustrate the high risk of both depression and adverse birth outcomes among WHIV and underscore the need for interventions to improve their mental health and the health of their infants; however, the relationship between depression and birth outcomes remains unclear. Further research on this topic is merited, particularly examining the chronicity and timing of depression in pregnancy.

INTRODUCTION: Children who are born to women living with HIV are at a greater risk of suboptimal neurodevelopment; however, evidence from sub-Saharan Africa is limited and functional developmental outcomes are rarely assessed in this vulnerable population. The School Readiness among HIV-Exposed Children (SRHEC) cohort study aims to assess the school readiness of preschool aged children born to women living with HIV and to identify the biological, environmental and social factors that contribute to school readiness in this population. METHODS AND ANALYSIS: The SRHEC cohort is an observational follow-up study of children born to HIV-infected pregnant women who were previously enrolled in a maternal vitamin D supplementation randomised, placebo-controlled trial in Dar es Salaam, Tanzania. This parent trial enrolled 2300 pregnant women and followed mothers and infants up to 1-year postpartum. Mother/caregiver and child pairs will be eligible for the SRHEC follow-up study if the child is between 3 and 6.5 years of age at assessment, and the mother/caregiver provides informed consent. The International Development and Early Learning Assessment tool will be used to assess children's school readiness, including their early literacy, early numeracy, motor, socialemotional, and executive function skills. Data on maternal and child health and nutritional status (eg, anthropometry, blood pressure and diet) will be collected using standardised instruments and survey-based questionnaires. Data on maternal/caregiver depression and anxiety, maternal exposure to intimate partner violence, and HIV-related stigma will also be collected. Generalised linear and logistic regressions will be used to assess the relationship between child school readiness and biological, social, environmental factors. ETHICS AND DISSEMINATION: This study received ethical clearance from the Tanzanian National Institute of Medical Research, the Muhimbili University of Health and Allied Sciences, and the Harvard T.H. Chan School of Public Health. We will disseminate our results in the form of scientific conference presentations and peer-reviewed publications.
