Abstract
AIMS: To assess the effect of physical activity in patients with type 2 diabetes mellitus on prevention of diabetes with chronic kidney disease. METHODS: This is a cohort study on stratified selected subjects in Taiwan from 2004/01/01 to 2005/12/31. Demographic data, lifestyle factors and clinical characteristics were analyzed for an association with the occurrence of chronic kidney disease. Applicable analysis weights, Stata 11.0, were applied to adjust the design variables for clustering and stratification. RESULTS: During the two year study period, the univariate Cox proportional hazards model showed significant associations of age, physical activity, and the Charlson comorbidity index (CCI) with chronic kidney disease. Physical activity had a beneficial effect in diabetic subjects with chronic kidney disease (HR: 0.31, p<0.01). Older age and a CCI greater than 2 were both harmful in diabetic subjects with chronic kidney disease (1.06 and 3.44, respectively). The results of a multivariate Cox proportional hazards evaluation model were similar to those of a univariate evaluation model, except that CCI was not significantly different. Moreover, medications for hypertension of diabetic subjects created an increased risk of chronic kidney disease (HR: 5.85 and 3.74, respectively), indicating that the presence of hypertension is a strong risk factor for the progression of chronic kidney disease. CONCLUSION: In this study, physical activity was not only a healthful lifestyle factor but also a treatment to decrease incidence of chronic kidney disease in diabetic patients.
