AbstractBackground/Aims:Although a low level of high-density lipoprotein cholesterol (HDL-C) is an independent risk factor for atherosclerotic heart disease, the mechanism of HDL-C abnormality in hemodialysis (HD) as well as peritoneal dialysis (PD) patients is not fully understood. The purpose of this study was to investigate the relationship of physical activity with HDL-C subfractions and lecithin:cholesterol acyltransferase activity in HD and PD patients. Methods:Thirty-five HD and 26 PD patients were studied. Physical activity was estimated as the average number of steps taken per day over 7 days (steps/day). Results:When possible confounding factors were included in the stepwise multiple regression analyses, in HD patients, steps/day was significantly positively related to HDL2-C and apolipoprotein (Apo) A-I, while it was significantly positively related to HDL3-C in PD patients. When subjects were subdivided into 3 groups according to steps/day, in HD patients, the highest category of steps/day had significantly higher HDL2-C and Apo A-I than the lowest category, while such results were not observed in PD patients. Conclusion:These results suggest that the associations of physical activity with HDL-C subfractions and Apo A-I that are known in the general population are more pronounced in HD patients than PD patients.Copyright © 2009 S.
