^*P values and partial eta squared are shown for analysis using physical activity, sedentary behaviours and eating habits as continuous variables, without any adjustments.

¹P value: The mean difference is significant at the 0.05 level or less.

²PES: partial eta squared (proportions of variance).

³Moderate activities include activities such as normal pace walking, brisk walking, recreational swimming, badminton, table tennis.

⁴Vigorous activities include activities such as jogging, running, self-defence, weight training, soccer, basketball.

⁵At least moderate activities include both moderate and vigorous activities.
