p-value from Kruskal-Wallis test for the difference in participation in physical activity by gender.

Time spent in various intensities of activity from accelerometer: moderate-to-vigorous activity ≥760 ct/min; light activity 100 ct/min-759 ct/min; sedentary behavior.

Time spent in various intensities of activity as reported on PAQ1, PAQ2 and the PA-log: moderate-to-vigorous activity >3.0 METs; light activity 2.0–3.0 METs; sedentary behavior.

Among employed participants.

¥

Active transport includes walking or cycling for work or getting about.

§

p-value from Wilcoxon sign-rank test for the difference in participation in physical activity subcomponents from accelerometer with PAQ1, PAQ2 and with the PA-log <0.05 for all physical activity variables except occupational activity.
