aPrimary cohort includes singletons and one randomly selected multiple of a set.
Model 1 adjusted for infant age, gender and their interactions, maternal age (years), maternal race (White, Black, Asian, Hispanic, other), education (less than HS, HS, some college, college, advanced), pregnancy smoking (yes/no), private insurance (yes/no), maternal pre-pregnancy BMI (kg/m2) and paternal BMI (kg/m2). Bold value indicates significance at P < 0.05.
