P-value is for ethnic difference by two-way ANOVA. Gender and gender × ethnicity effects were not detected.

^*Ethnic differences in gender and tanner stage distributions were determined by Mann Whitney U-test.

^†Physical activity score was determined using the physical activity questionnaire for children (see refs. 23, 24). Scoring range 1-5: the higher the score the higher the physical activity.
