  1. aChildren with height-for-age Z scores < − 2 SD were classified as stunted
  2. bChildren with weight-for-age Z scores < − 2 SD were classified as underweight
  3. cWAMI index was based on water and sanitation facility, household assets, mother’s education, and total income
  4. d Mean blood lead levels were obtained by taking average of lead values measured at 15, 24 and 36 months of age
  5. eDependent variables considered for analysis were cognition, language, and motor domains of BSID-III scores. Regression co-efficients were derived using generalized estimating equations and the model fitness was assessed for each domain separately using Wald statistics and P value was noted as < 0.0001
