  1. Note: Model-specific covariates included 1) gestational age: pre-pregnancy BMI, MET∙min∙week−1; 2) preterm: pre-pregnancy BMI, MET∙min∙week− 1; 3) cesarean section: MET∙min∙week− 1; 4) birthweight: MET∙min∙week− 1; and 5) low birthweight: MET∙min∙week− 1. a Median regression was performed and the respective βs were reported. b Poisson regression was performed, and the respective relative risks are reported. c Linear regression was performed and the respective βs were reported
