1Units = kg per HEI-score standard deviation ( = 7.31 for HEI-NFG, 2.54 for HEI-NNR).
2Linear regression model, adjusted for maternal age, maternal education, household income, marital status, pre-pregnancy BMI, parity, weight of the child at birth, breastfeeding duration up to 6 months postpartum, total energy intake (kcal), exercise during pregnancy (week 15), smoking during pregnancy, alcohol intake during pregnancy (week 22).
3Analogous model but without adjustment for breastfeeding duration.
