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
