  • M ± SD, unless otherwise indicated. All values are weighted to account for oversampling in low-income neighborhoods. Mazes range = 1–19; verbal comprehension range = 51–149); CSI-4 range = 40–97; ChEAT range = 1–6. For BMI and ChEAT binge-eating frequency, means correspond to normal weight or overweight/obese status measured at the same time point (eg, mean BMI at age 10 is reported for girls who were normal weight versus overweight/obese at age 10; mean BMI at age 12 is reported for girls who were normal weight versus overweight/obese at age 12). All other values reflect measurement at age 10. Subgroup %/n values do not add up to full sample %/n values because of missing data.
