Multilevel linear regression models with exchangeable correlation structure, robust standard errors, and adjustments prepregnancy BMI (normal weight, overweight, or obese), parent study intervention assignment (nonintervention, treatment, or comparison group), gestational age at the study visit (first, second, or third trimester), and study visit length (continuous).
