  • Values are provided as proportion.

  • *p Values calculated from χ2 test.

  • †Adjusted significance level using the Holm's method36 for multiple testing, the first entry being the adjusted significance level and the rank in parentheses the rank of the associated original p value in ascending order from most-to-least significant.

  • ‡Statistically significant (p<0.05) after adjustment for multiple testing using the Holm's method. Missing number of cases: children's overweight (252), parental status (3), and meal regularity (286); mothers living with children (n=1532): maternal employment status (66), habitual exercise (65), and screen time (152); fathers living with children (n=1412): habitual exercise (58) and screen time (94).
