Abbreviations: CI, confidence interval; BMI, body mass index; wk, week. Data were expressed as mean ± standard deviation unless otherwise indicated. * Geometric mean ± standard deviation; ^a paired t-test between baseline data and 16-wk follow-up data. ^b group × time interaction effects adjusted for age and sex in the mixed effects linear regression models (random intercept: individual). ^c group × time interaction effects adjusted for age, sex, parental obesity, parental education, monthly household income, marital status, and sleep time, in the mixed effects linear regression models (random intercept: individual).
