Maternal health and birth outcomes in a South African birth cohort study.

BACKGROUND: Maternal physical and mental health during pregnancy are key determinants of birth outcomes. There are relatively few prospective data that integrate physical and mental maternal health measures with birth outcomes in low- and middle-income country settings. We aimed to investigate maternal health during pregnancy and the impact on birth outcomes in an African birth cohort study, the Drakenstein Child Health Study. METHODS: Pregnant women attending 2 public health clinics, Mbekweni (serving a predominantly black African population) and TC Newman (predominantly mixed ancestry) in a poor peri-urban area of South Africa were enrolled in their second trimester and followed through childbirth. All births occurred at a single public hospital. Maternal sociodemographic, physical and psychosocial characteristics were comprehensively assessed. Multivariable linear regression models were used to explore associations between maternal health and birth outcomes. RESULTS: Over 3 years, 1137 women (median age 25.8 years; 21% HIV-infected) gave birth to 1143 live babies. Most pregnancies were uncomplicated but gestational diabetes (1%), anaemia (22%) or pre-eclampsia (2%) occurred in a minority. Most households (87%) had a monthly income of less than USD 350; only 27% of moms were employed and food insecurity was common (37%). Most babies (80%) were born by vaginal delivery at full term; 17% were preterm, predominantly late preterm. Only 74 (7%) of babies required hospitalisation immediately after birth and only 2 babies were HIV-infected. Food insecurity, socioeconomic status, pregnancy-associated hypertension, pre-eclampsia, gestational diabetes and mixed ancestry were associated with lower infant gestational age while maternal BMI at enrolment was associated with higher infant gestational age. Primigravida or alcohol use during pregnancy were negatively associated with infant birth weight and head circumference. Maternal BMI at enrolment was positively associated with birth weight and gestational diabetes was positively associated with birth weight and head circumference for gestational age. Smoking during pregnancy was associated with lower infant birth weight. CONCLUSION: Several modifiable risk factors including food insecurity, smoking, and alcohol consumption during pregnancy were identified as associated with negative birth outcomes, all of which are amenable to public health interventions. Interventions to address key exposures influencing birth outcomes are needed to improve maternal and child health in low-middle income country settings.

Investigating tangible and mental resources as predictors of perceived household food insecurity during pregnancy among women in a South African birth cohort study.

RATIONALE: Food insecurity during pregnancy is concerning given the increased nutritional needs of the mother for proper fetal development. However, research is lacking within the South African context to investigate the association of economic and psychosocial factors and food insecurity among pregnant women, using comprehensive, conceptually driven models. OBJECTIVE: This study applies the Network-Individual-Resource (NIR) Model to investigate individual, intimate dyadic, and family level predictors of perceived household food insecurity for pregnant women. METHODS: 826 pregnant women enrolled in the Drakenstein Child Health Study (DCHS), a birth cohort in two communities in a peri-urban area of South Africa. Hierarchical logistic regressions were used to investigate the impact of household/family, intimate dyads, and individual tangible and mental resources on perceived household food insecurity during the critical period of pregnancy. Perceived household food insecurity was assessed through an adapted version of the USDA Household Food Security Scale - Short Form. RESULTS: Among 826 pregnant women in South Africa, individual-level tangible resources (e.g. income, social assistance, HIV status) and mental resources (e. g. depression, childhood trauma) predicted perceived household food insecurity and these predictors differed by community. Intimate dyadic and family level resources did not predict household food insecurity. CONCLUSIONS: Our findings of the economic and psychosocial predictors of perceived household food insecurity among pregnant women in South Africa, mirror findings in general populations. This study provides support for the extension of the NIR model to perceived household food insecurity, particularly regarding individual-level mental and tangible resources, as well as the impact of community-level factors. Future research should investigate the extent to which resource sharing occurs within networks.

A pandemic of the poor: social disadvantage and the U.S. HIV epidemic.

The U.S. HIV/AIDS epidemic has evolved over the past 30 years and is now concentrated in socially marginalized and disenfranchised communities. The health disparities in this epidemic are striking, with most HIV infections occurring in sexual minorities and communities of color. While widely recognized, the health disparities in HIV and AIDS are not often discussed. In this article, we examine the factors underlying health disparities in the U.S. HIV epidemic. We first discuss the interlocking relationships between biological, social, and behavioral factors that drive HIV/AIDS epidemics. Guided by a well-established conceptual model of health disparities, we then describe the social positions of those most affected by HIV and AIDS, particularly racial and gender groups. Structural and economic conditions-including environmental resources, constraints, access to care, and psychosocial influences-are examined in relation to HIV disease trajectories. Greater attention to contextual factors and comorbidities is needed to reduce the health disparities in HIV/AIDS.

Barriers to care for rural people living with HIV: a review of domestic research and health care models.

Historically, the availability of heath care in rural areas has been sparse, and specialized care for people living with HIV (PLWH) has been especially problematic. Rural patients are faced with substantially greater barriers to care than their urban counterparts. A systematic review of empirical studies was conducted concerning barriers to care among patients infected with HIV in rural areas of the United States. This systematic review yielded 15 viable articles for analysis. Among the 27 barriers identified, the most commonly discussed were transportation needs, provider discrimination and stigma, confidentiality concerns, and affordability and lack of financial resources. Barriers to care must be addressed in conjunction with one another in order to alleviate their impacts. Key health care models addressing these concerns are highlighted and used to address the state of the field and provide suggestions for future research.

Service priorities and unmet service needs among people living with HIV/AIDS: results from a nationwide interview of HIV/AIDS housing organizations.

Housing for people living with HIV/AIDS (PLWHA) has been linked to a number of positive physical and mental health outcomes, in addition to decreased sexual and drug-related risk behavior. The current study identified service priorities for PLWHA, services provided by HIV/AIDS housing agencies, and unmet service needs for PLWHA through a nationwide telephone survey of HIV/AIDS housing agencies in the USA. Housing, alcohol/drug treatment, and mental health services were identified as the three highest priorities for PLWHA and assistance finding employment, dental care, vocational assistance, and mental health services were the top needs not being met. Differences by geographical region were also examined. Findings indicate that while housing affords PLWHA access to services, there are still areas (e.g., mental health services) where gaps in linkages to care exist.
