Social Support, Stigma and Antenatal Depression Among HIV-Infected Pregnant Women in South Africa.

ABSTRACT: Depression, HIV-related stigma and low levels of social support may be particularly prevalent and adversely affect health and treatment outcomes among HIV-infected pregnant women. We examined factors associated with social support and stigma among pregnant women initiating antiretroviral therapy in the Western Cape, South Africa; and explored associations with depressive symptoms (Edinburgh Postnatal Depression Scale; EPDS) in linear regression models. Among 623 participants, 11 and 19 % had elevated EPDS scores using thresholds described in the original development of the scale (scores ?13 and ?10, respectively). Social support and stigma were highly interrelated and were associated with depressive symptoms. Stigma was observed to moderate the association between social support and depression scores; when levels of stigma were high, no association between social support and depression scores was observed. Elevated depression scores are prevalent in this setting, and interventions to reduce stigma and to address risk factors for depressive symptoms are needed.

Project description:Food insecurity has emerged as an important, and potentially modifiable, risk factor for depression. Few studies have brought longitudinal data to bear on investigating this association in sub-Saharan Africa.To estimate the association between food insufficiency and depression symptom severity, and to determine the extent to which any observed associations were modified by social support.We conducted a secondary analysis of population-based, longitudinal data collected from 1238 pregnant women during a three-year cluster-randomized trial of a home visiting intervention in Cape Town, South Africa. Surveys were conducted at baseline, 6 months, 18 months, and 36 months (85% retention). A validated, single-item food insufficiency measure inquired about the number of days of hunger in the past week. Depression symptom severity was measured using the Xhosa version of the 10-item Edinburgh Postnatal Depression Scale. In multivariable regression models with cluster-correlated robust estimates of variance, lagged food insufficiency had a strong and statistically significant association with depression symptom severity (? = 0.70; 95% CI, 0.46-0.94), suggesting a 6.5% relative difference in depression symptom severity per day of hunger. In stratified analyses, food insufficiency had a statistically significant association with depression only among women with low levels of instrumental support. Using quantile regression, we found that the adverse impacts of food insufficiency were experienced to a greater degree by women in the upper end of the conditional distribution of depression symptom severity. Estimates from fixed-effects regression models and fixed-effects quantile regression models, accounting for unobserved confounding by time-invariant characteristics, were similar.Food insufficiency was associated with depression symptom severity, particularly for women in the upper end of the conditional depression distribution. Instrumental social support buffered women against the adverse impacts of food insufficiency.

Project description:IntroductionNew HIV infection during pre-conception and pregnancy is a significant contributor of mother-to-child transmission of HIV in South Africa. This study estimated HIV incidence (defined as new infection within the last one year from the time of the survey which included both new infections occurred during pregnancy or just before pregnancy) among pregnant women and described the characteristics of recently infected pregnant women at national level.MethodsBetween 1 October and 15 November 2017, we conducted a national cross-sectional survey among pregnant women aged 15-49 years old attending antenatal care at 1,595 public facilities. Blood specimens were collected from pregnant women and tested for HIV in a centralised laboratory. Plasma viral load and Limiting Antigen Avidity Enzyme Immunosorbent Assay (LAg) tests were further performed on HIV positive specimens to differentiate between recent and long-term infections. Recent infection was defined as infection that occurred within one year from the date of collection of blood specimen for the survey. Data on age, age of partner, and marital status were collected through interviews. Women whose specimens were classified as recent by LAg assay and with viral loads >1,000 copies/mL were considered as recently infected. The calculated proportion of HIV positive women with recent infection was adjusted for assay-specific parameters to estimate annual incidence. Survey multinomial logistic regression was used to examine factors associated with being recently infected using HIV negative women as a reference group. Age-disparate relationship was defined as having a partner 5 or more years older.ResultsOf 10,049 HIV positive participants with LAg and viral load data, 1.4% (136) were identified as recently infected. The annual HIV incidence was 1.5% (95% confidence interval (CI): 1.2-1.7). In multivariable analyses, being single (adjusted odds ratio, aOR: 3.4, 95% CI: 1.8-6.2) or cohabiting (aOR: 3.8, 95% CI: 1.8-7.7), compared to being married as well as being in an age-disparate relationship among young women (aOR: 3.1, 95% CI: 2.0-4.7; reference group: young women (15-24years) whose partners were not 5 years or more older) were associated with higher odds of recent infection.ConclusionsCompared to previous studies among pregnant women, the incidence estimated in this study was substantially lower. However, the UNAIDS target to reduce incidence by 75% by 2020 (which is equivalent to reducing incidence to <1%) has not been met. The implementation of HIV prevention and treatment interventions should be intensified, targeting young women engaged in age-disparate relationship and unmarried women to fast track progress towards the UNAIDS target.

Project description:Antiretroviral treatment (ART) initiation in HIV-infected pregnant women in sub-Saharan Africa (SSA) remains inadequate, and there is a severe shortage of professional healthcare workers in the region. The effectiveness of community support programmes for HIV-infected pregnant women and their infants in SSA is unclear. This study compared initiation of maternal antiretrovirals and infant outcomes amongst HIV-infected pregnant women and their infants who received and did not receive community-based support (CBS) in a high HIV-prevalence setting in South Africa. A cohort study, including HIV-infected pregnant women and their infants, was conducted at three sentinel surveillance facilities between January 2009 and June 2012, utilising enhanced routine clinical data. Through home visits, CBS workers encouraged uptake of interventions in the ART cascade, provided HIV-related education, ART initiation counselling and psychosocial support. Outcomes were compared using Kaplan-Meier analyses and multivariable Cox and log-binomial regression. Amongst 1105 mother-infant pairs included, 264 (23.9%) received CBS. Amongst women eligible to start ART antenatally, women who received CBS had a reduced risk of not initiating antenatal ART, 5.4% vs. 30.3%; adjusted risk ratio (aRR)?=?0.18 (95% CI: 0.08-0.44; P?<?.0001). Women who received CBS initiated antenatal ART with less delay after the first antenatal visit, median 26 days vs. 39 days; adjusted hazard ratio (aHR)?=?1.57 (95% CI: 1.15-2.14; P?=?.004). Amongst women who initiated antenatal zidovudine (ZDV) to prevent vertical transmission, women who received CBS initiated ZDV with less delay, aHR?=?1.52 (95% CI: 1.18-2.01; P?=?.001). Women who received CBS had a lower risk of stillbirth, 1.5% vs. 5.4%; aRR?=?0.24 (95% CI: 0.07-1.00; P?=?.050). Pregnant women living with HIV who received CBS had improved antenatal triple ART initiation in eligible women, women initiated ART and ZDV with shorter delays, and had a lower risk of stillbirth. CBS is an intervention that shows promise in improving maternal and infant health in high HIV-prevalence settings.
