Are early childhood stunting and catch-up growth associated with school age cognition?-Evidence from an Indian birth cohort.

This study showed persistent stunting in childhood was associated with lowering of 4-5 IQ points in childhood cognition at 9 years of age. Recovery from early life stunting in children with catch up growth prevented further lowering of cognition scores in these children compared to persistently stunted children. Nutritional supplementation during late infancy and early toddlerhood in addition to continuing nutritional supplementation programmes for preschool and school children can improve childhood stunting and cognitive abilities in vulnerable populations.
