We examine to what extent there is an empirical linkage between income growth and reductions of child undernutrition in Africa. We pool all DHS surveys for African countries, control for other correlates of undernutrition, and add country‐level GDP per capita. We find that a 10 percent increase in GDP per capita is associated with 1.5 to 1.7 percent lower odds of being stunted, 2.8 to 3.0 percent lower odds of being underweight, and 3.5 to 4.0 percent lower odds of being wasted. Other drivers of undernutrition, including relative socioeconomic status and mother's education and her nutritional status, are quantitatively more important. This suggests that further increases in GDP will have only a modest impact on undernutrition and broader interventions are required to accelerate progress."],["dc.identifier.doi","10.1111/j.1728-4457.2013.00609.x"],["dc.identifier.uri","http://hdl.handle.net/2/14763"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.title","Economic Growth and Child Undernutrition in sub-Saharan Africa"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dspace.entity.type","Publication"]]

Methods We used nationally representative cross-sectional data from the 2015–16 India National Family and Health Survey (NFHS-4). The study population comprised 444 611 mothers aged 15–49 years. We used the sex of the first-born child as an instrumental variable (IV) for the total number of a woman’s children. We estimated the effect of an additional child on systolic and diastolic blood pressure in IV (two-stage least squares) regressions. In additional analyses, we stratified the IV regressions by time since a mother last gave birth. Furthermore, we repeated our analyses using mothers' husbands and partners as the regression sample. Results On average, mothers had 2.7 children [standard deviation (SD): 1.5], a systolic blood pressure of 116.4 mmHg (SD: 14.4) and diastolic blood pressure of 78.5 mmHg (SD: 9.4). One in seven mothers was hypertensive. In conventional ordinary least squares regression, each child was associated with 0.42 mmHg lower systolic [95% confidence interval (CI): –0.46 to –0.39, P < 0.001] and 0.13 mmHg lower diastolic (95% CI: –0.15 to –0.11, P < 0.001) blood pressure.
