SC, step counts; ST, screen time; % ^a, proportion of children (daughter, sons) who met the pedometer-based recommendation for daily step counts 11,500 steps/day in a given row (e.g. 60.6 % of the children, whose mothers reached ≥ 10,000 steps/day on weekdays, met the recommendation of 11,500 steps/day); OR, odds ratio; 95 % CI, confidence interval; Ref., reference group
