Assessment of environmental exposure factors on child diarrhea and systemic inflammation in the Eastern Cape.

Poor environmental technologies and gastrointestinal illnesses have been hypothesized to be a primary cause to the lack of impact of child health programs on child stunting rates (low height-for-age) in South Africa. This study assessed correlations between environmental exposures (water source, water treatment, sanitation, refuse), diarrheal occurrences, and systemic inflammation proxies among female and male children under five years of age in the Eastern Cape. A conceptual model was hypothesized using structural equation (SE) modeling and two sex-specific (female and male) datasets were subsequently generated from the data and applied to the hypothesized SE model. Results suggested that environmental exposure variables associated with diarrhea and systemic inflammation proxies were different between females and males. For diarrheal occurrences among females, an increase in local authority management of refuse (compared to household management) (0.161, p-value (p) = 0.007), sharing sanitation facilities (0.060, p = 0.023), and a decrease in the frequency of the treatment of drinking water (-0.043, p = 0.025) were correlated with an increase in diarrhea. For males, an increase in household use of flush toilets (as compared to ventilated pit latrines) was correlated with an increase in diarrhea (0.113, p = 0.027). For systemic inflammation among both sexes, an increase in household use of water pumped into the premises (as compared to a public water tap) and an increase in diarrheal occurrences were correlated with an increase in systemic inflammation. The data support an increased focus on sex and gender specific factors among field practitioners and policy makers working in the environmental health field in South Africa.

Persistence of the inverse care law in maternal health service utilization: An examination of antenatal care and hospital delivery in Ghana.

The gap in maternal health outcomes, access and utilization between the haves and have-nots continues to be a challenge globally despite improvements over the past decade. Though Ghana has experienced steady gains in maternal health access and utilization over the years, maternal outcomes, on the other hand, remain poor. In this regard, it is essential to know how various groups in the population achieved improvements and whether some women continue to be disproportionately disadvantaged. The paper performs an analysis of cross-sectional data from the 2017 Ghana maternal health survey to examine the existence of the inverse care law in maternal health services in Ghana. Using descriptive techniques and multivariate logistic regression models the study reveals a pro-rich and pro-urban gradient in the use of hospital facilities for delivery and antenatal care attendance - also, regions known for their high levels of poverty feature significantly lower rates of hospital deliveries. The paper concludes by stressing that unless policies are changed to accommodate these groups, overall gains in maternal health will continue to be incremental.

A comparative analysis of socioeconomic inequities in stunting: a case of three middle-income African countries.

BACKGROUND: Despite increased economic growth and development, and existence of various policies and interventions aimed at improving food security and nutrition, majority of countries in sub-Saharan Africa have very high levels of child malnutrition. The prevalence of stunting, an indicator of chronic malnutrition, is especially high. METHODS: In this paper, we use Demographic and Health Survey datasets from three countries in the region that obtained middle-income status over the last decade (Ghana, Kenya and Zambia), to provide a comparative quantitative assessment of stunting levels, and examine patterns in stunting inequalities between 2007 and 2014. RESULTS: Our analyses reveal that stunting rates decreased in all three countries over the study period, but are still high. In Zambia, 40% of under 5-year olds are stunted, compared to 26% in Kenya and 19% in Ghana. In all three countries, male children and those living in the poorest households have significantly higher levels of stunting. We also observe stark inequalities across socio-economic status, and show that these inequalities have increased over time. CONCLUSIONS: Our results reveal that even with economic gains at the national level, there is need for continued focus on improving the socio-economic levels of the poorest households, if child nutritional outcomes are to improve.
