Data are presented as median (IQR) unless otherwise noted. MET-h, Metabolic Equivalent Task hour; NPAAS-FS, Nutrition and Physical Activity Assessment Study Feeding Study (n = 145); SSB, sugar-sweetened beverage.
2
Differences across tertiles of added sugar intake were assessed with either a χ2 square test (race, current smokers) or a Kruskal–Wallis test (all other variables). P < 0.05 was considered significant.
3
Race included 95% white and 5% nonwhite/race unknown (3 African American, 1 American Indian/Alaska Native, 1 Asian/Pacific Islander, and 2 race unknown).
