	Model 1 B (95% CI)	Model 2 B (95% CI)
PA type (hours/week)
Walking	3.5 (2.4 to 4.6)*	2.3 (1.2 to 3.4)*
Cycling	0.4 (0.0 to 0.7)*	0.2 (−0.2 to 0.5)
Exercise	0.1 (−0.2 to 0.3)	0.0 (−0.2 to 0.3)
Chores	0.6 (−0.3 to 1.4)	−0.3 (−1.2 to 0.6)
PA intensity (hours/week)
Moderate PA	4.1 (2.6 to 5.5)*	2.0 (0.5 to 3.4)*
Vigorous PA	0.5 (0.0 to 0.9)*	0.2 (−0.3 to 0.7)
	Model 1 OR (95% CI)	Model 2 OR (95% CI)
Sports activities
Plays sports (yes)	0.9 (0.7 to 1.0)	0.9 (0.7 to 1.1)
Type of sports (non-individual)	0.9 (0.7 to 1.3)	1.0 (0.7 to 1.3)
Sports intensity (≥6.0 MET)	1.2 (0.9 to 1.6)	1.2 (0.9 to 1.7)

Reference group: non-shift workers.

Model 1: adjusted for age, gender, educational level, marital status, smoking status and diet; model 2: model 1+adjusted for occupational PA.
