Note: Low SES was determined if the female guardian had no high school degree, a high school degree, or some college experience; IQ = intelligent quotient; BMI = body mass index; Data are presented as mean (±1 SEM) unless noted otherwise. Values sharing a common superscript are not statistically different at p ≤ .05.
