Changes in physical activity and sedentary behavior levels during lockdown vs. pre-COVID-19, and changes in PA and sedentary behavior after lockdown lifted vs. pre-COVID-19 among participating youths.

PA, physical activity.

The categories “increased,” “constant,” and “decreased” reflect the changes of PA levels (none, 1–149 min/weeks, and ≥150 min/weeks). For instance, if one moved from ≥150 min/weeks to 1–149 min/week, then deemed as “decreased.” The same applies to sedentary time levels (<2 h/days and ≥2 h/days).

χ² tests were performed to examine the significance of differences in changes in PA and sedentary behavior levels between sexes.
