statistics for the FHS G3 sample that we use in our analysis by educational status. Those without a college degree have an average BMI that is 1.44 units higher than those with a college degree (p < .001). This is a moderate effect size (Cohen's D ~ .3) and translates to roughly 10 additional pounds for a 140-pound adult who is 5′8″. There are no gender differences by educational attainment, but we do see that our college-educated sample is slightly younger. We include these controls in the genome-wide association models described later.
