The Association between Sitting Time, Physical Activity Level and Chronic Kidney Disease in the Healthy Adults / 대한스포츠의학회지

ABSTRACT

This study aimed to examine the prevalence of chronic kidney disease (CKD) in association with physical activity and sitting time. Participants of this study are Korean men and women aged 40 to 69, who completed health examination from 2001 to 2003. Physical activity was measured by using an International Physical Activity questionnaire. CKD was defined by estimated glomerular filtration rate that is lower than 60 mL/min/1.73 m². Logistic regression was conducted to evaluate the association of sitting time and physical activity with CKD (p<0.05). When age, sex, and other risk factor of CKD are adjusted, subjects who reported high level of physical activity participation had a significantly lower odds ratio (OR) of CKD than subjects who reported as sitting low level of physical activity participation (OR, 0.70; 95% confidence interval [CI], 0.50–0.99), and subjects who spend more than 5 hours had significantly higher OR of CKD than subjects who spend less than 1 hours (OR, 1.63; 95% CI, 1.13–2.37). Multivariate-adjusted OR of CKD associated with sitting time more than 5 hours (OR, 2.21; 95% CI, 1.09–4.52) and high physical activity participation more than 1 hours (OR, 0.48; 95% CI, 0.23–0.99) and 5 hours (OR, 0.47; 95% CI, 0.24–0.90) were significant in men. High level of physical activity and low level of sitting time were independently associated with OR of CKD, and this supports the importance of reducing sitting time as well as promoting physical activity participation.
