The p value is the result of a Wilcoxon test in analyses with two categories (sex, sleep during the day), and a Kruskal–Wallis test was used in analyses with three or more categories (physical activity duration per day, physical activity type, screen time duration during the day, type of screen most often used, sleep duration during the day)
*p value < 0.05 was considered statistically significant when comparing BMI and waist circumference between daily movement behaviour categories
