Table 2 Adjusted linear regression models of the associations between pre-pregnancy body mass index and total gestational weight gain with INTER-NDA score percentiles by domain at 24-month follow-up assessment in the 2015 Pelotas (Brazil) Birth Cohort, stratified by child’s sex.

From: Poor maternal nutritional status before and during pregnancy is associated with suspected child developmental delay in 2-year old Brazilian children
