^aModel 1 adjusted for baseline WHZ1, baseline age, gender, race/ethnicity, birthweight, maternal language preference, maternal educational level, maternal age, family size, family monthly income, follow-up time.

^bModel 2 adjusted for model 1 covariates and maternal BMI

Note that the model for WHZ₃ further included interaction terms between race and WHZ₂ and between WHZ₁ and WHZ₂. No interaction was included in the WHZ₂ model
