Public health interventions to improve maternal nutrition during pregnancy: a nationally representative study of iron and folic acid consumption and food supplements in India.

OBJECTIVE: Despite a reduction in maternal mortality in recent years, a high rate of anaemia and other nutrient inadequacies during pregnancy pose a serious threat to mothers and their children in the Global South. Using the framework of the WHO-Commission on Social Determinants of Health, this study examines the socioeconomic, programmatic and contextual factors associated with the consumption of iron and folic acid (IFA) tablets/syrup for at least 100 d (IFA100) and receiving supplementary food (SF) by pregnant women in India. DESIGN: We analysed a nationally representative cross-sectional survey of over 190 898 ever-married women aged 15-49 years who were interviewed as part of the National Family Health Survey (NFHS) conducted during 2015-16, who had at least one live birth preceding 5 years of the survey. SETTING: All twenty-nine states and seven union territories of India. PARTICIPANTS: Ever-married women aged 15-49 years. RESULTS: Less than one-third of women were found to be consuming IFA100, and a little over half received SF during their last pregnancy. The consumption of IFA100 was likely to improve with women's education, household wealth, early and more prenatal visits, and in a community with high pregnancy registration. Higher parity, early and more prenatal visits, contact with community health workers during pregnancy, belonging to a poor household and living in an aggregated poor community and rural area positively determine whether a woman might receive SF during pregnancy. CONCLUSIONS: Continuous monitoring and evaluation of provisioning IFA and SF in targeted groups and communities is a key to expanding the coverage and reducing the burden of undernutrition during pregnancy.
