Model 1 includes race + covariates (gender, age, puberty stage, prematurity, and birth weight). Model 2 includes parent education + covariates. Model 3 includes both race and parent education + covariates. Model 4 adds breastfeeding for >4 months, the proposed mediator, to model 3.

^aReferent categories are white and college degree or more.

^bReferent category is breastfeeding for 0 to 4 months.
