Table 2. Adjusted association between physical activity scores category and odds of having ≥ 1, 2, 3 CVDMRF (OR, 95% CI).

	≥ 1 CVDMRF			≥ 2 CVDMRF			≥ 3 CVDMRF
	Moderate PA	High PA		Moderate PA	High PA		Moderate PA	High PA
Adjusted OR was estimated with low physical activity as reference group. CVDMRF: cardiovascular disease modifiable risk factors; PA: physical activity.
