Mean 5‐y changes in aBMI were obtained from age group– and sex‐stratified regression models that adjusted for age (continuous). P 1 denotes P value from testing whether 5‐y changes in aBMI are different from zero in each ethnic group. P 2 denotes P value from testing whether 5‐y changes in each ethnic group are different from respective 5‐y changes in White children.
