This study address persistent wealth inequality in anthropometric failure in India by analyzing two rounds of the Indian National Family Health Survey (2019-2021 and 2015-2016) focusing on children aged 0–59 and 6–23 months, reveals a negative wealth gradient for each anthropometric failure measure. Over 60% of the anthropometric failure burden lies in the poorest wealth groups. Notably, even with similar risk factors, children from poorer backgrounds exhibit higher prevalence. Maternal BMI, media exposure, and sanitary facility access are key factors explaining the poor-rich gap.
