Abstract
BACKGROUND: Childhood anaemia remains a significant public health problem in India, as it adversely affects child development and overall health outcomes. This study aimed to analyse the prevalence of severe and moderate anaemia among children aged 6-59 months and identify consistent predictors of this condition over the past 15 years. METHODS: Data from the three most recent rounds of the NFHS were used for this analysis. The final weighted sample included 40,331 children from the NFHS-3 (2005-2006), 200,093 from the NFHS-4 (2015-2016), and 178,909 from the NFHS-5 (2019-2021). Descriptive and bivariate analyses were conducted, followed by binary logistic regression to identify factors associated with severe and moderate anaemia in children aged 6-59 months. All statistical analyses were performed using Stata version 14. RESULTS: Over the past 15 years, the prevalence of severe and moderate anaemia among children in India has shown a slight decline. However, the influence of various predictors has changed over time. Young children (aged 6-23 months), those from Scheduled Caste (SC) and Scheduled Tribe (ST) communities, and children born to mothers with high parity and low educational attainment remain particularly vulnerable to anaemia. Additionally, short-term illness significantly increases the risk of anaemia. Furthermore, women's autonomy, indicated by higher education and lower fertility rates, along with maternal nutrition education, have emerged as key factors in reducing anaemia burden in the future. Notably, children whose mothers had no education were 1.4 times more likely to suffer from severe or moderate anaemia. Similarly, children born to mothers with four to five children (OR 1.1, p < 0.05) and those with six or more children (OR 1.2, p < 0.05) had an elevated risk of anaemia. CONCLUSION: The findings highlight three key areas for programmatic focus to accelerate anaemia reduction in India: [1] targeting young children (aged 6-23 months); [2] ensuring the inclusion of SC and ST communities in all relevant interventions; and [3] promoting women's autonomy. These strategies are essential for reducing the burden of anaemia across the country.
