Get moving and preserve your kidneys

From the Archives of Internal Medicine:

Rapid decline in kidney function decline (RDKF) was defined by loss of more than 3.0 mL/min/1.73 m2 per year in glomerular filtration rate, which we estimated by using longitudinal measurements of cystatin C levels...

After multivariate adjustment, we found that the 2 highest PA groups (scores of 7-8) were associated with a 28% lower risk of RDKF (95% confidence interval, 21%-41% ower risk) than the 2 lowest PA groups (score of 2-3). Greater kilocalories of leisure-time PA and walking pace were also each associated with a lower incidence of RDKF.
