^a,b Estimates in the same row marked with different letters are statistically significantly different from each other (p < .01).
¹ Multiple regression models are adjusted for race/ethnicity, gender, socioeconomic status, total energy intake at Time 2, and dietary intake at Time 1.
² Vegetable intake does not include servings of French fries.
³ Whole grains intake does not include chip servings.
