Interactions between covariates and month age were included in the adjustment models: (1) Weight models: maternal pre-pregnancy BMI (24 to 36 months), maternal pregnancy disease (36 to 48 months), child gender (1 to 3 months, 6 to 12 months), child birth weight (3 to 6 months, 6 to 12 months); (2) Height models: maternal pre-pregnancy BMI (1 to 3 months), maternal history of gestation (24 to 36 months), maternal age (6 to 12 months), child gender (1 to 3 months, 6 to 12 months), child birth weight (1 to 3 months, 36 to 48 months), exclusive breastfeeding from birth to 1 month (1 to 3 months, 12 to 24 months), child disease from birth to 1 month (1 to 3 months).
PPD, postpartum depression; CI, confidence interval.
Level of significance: P < 0.05.
