PA Guideline (MVPA ≥150 min/week or not)			0.50 (0.36–0.70)	< .001	0.71 (0.50–1.03)	.07	0.89 (0.60–1.31)	.55

Abbreviations: CKD, chronic kidney disease; OR, odds ratio; CI, confidence interval; PA, physical activity; MVPA, moderate to vigorous physical activity; LIPA, light intensity physical activity.

Model 1 is unadjusted; Model 2 adjusted for age, sex, and accelerometer wear time; Model 3 adjusted for age, sex, accelerometer wear time, smoking, BMI, SBP, use of antihypertensive medication, diabetes, TC/HDL-C, use of lipid-lowering medication, and the prevalence of CVD at exam 9; All PA variables and sedentary time were considered as exposure variables (separate model for each); CVD includes fatal or nonfatal myocardial infarction, unstable angina (prolonged ischemic episode with documented reversible ST-segment changes), peripheral vascular disease (intermittent claudication), cerebrovascular disease (ischemic or hemorrhagic stroke or transient ischemic attack), or heart failure.
