Body mass index in Z-score.
Children’s Sleep Habits Questionnaire. β = standardized regression coefficient. Univariate model includes each sleep variable entered singularly. Multivariate model include each sleep variable entered simultaneously with covariates (age, sex, pubertal status, physical activity, screen time, socioeconomic status). Results remained consistent while adjusting for sleep duration (data not shown). Bolded values indicate statistical significance after Bonferonni corrections (p=0.0001).
