CI, confidence interval.
Boldface indicates P < 0.05.
aModel 1 adjusted for children’s sex and age, number of siblings, and children’s exercise time.
bModel 2 adjusted for covariates in model 1 plus parents’ age, parents’ educational attainment, equivalent household income and another parent’s working hours (maternal time for paternal time and vice versa).
