Physical Activity and Mortality in Chronic Kidney Disease (NHANES III)

BACKGROUND AND OBJECTIVES: Chronic kidney disease (CKD) is associated with impaired physical activity. However, it is unclear whether the associations of physical activity with mortality are modified by the presence of CKD. Therefore, we examined the effects of CKD on the associations of physical activity with mortality. DESIGN, SETTING, PARTICIPANTS, 5.9% had CKD (eGFR 0.3). CONCLUSIONS: Physical inactivity is associated with increased mortality in CKD and non-CKD populations. As in the non-CKD population, increased physical activity might have a survival benefit in the CKD population.
