THE DETERMINANTS OF SARCOPENIA AND DYNAPENIA IN IRANIAN PERITONEAL DIALYSIS PATIENTS IN 1394

Background and Aim: Uremic sarcopenia and dynapenia are prevalent in chronic kidney disease patients, including dialysis patients. The present study was designed to determine the prevalence of sarcopenia and dynapenia and their determinants in peritoneal dialysis (PD) patients in Tehran, Iran.Methods: All eligible PD patients at the peritoneal dialysis centers of Tehran were included in this cross-sectional study. Skeletal muscle mass and muscle strength were assessed using bioelectrical impedance analysis and hand grip strength, respectively. Physical performance was determined by a 4-m walk gait speed test.Results: The prevalence rates of dynapenia and sarcopenia were 43.0% and 11.5% in the PD patients, respectively. There were significant associations between the prevalence of dynapenia and the age of patients (P = .03), physical activity level (P = .04), and the presence of diabetes mellitus (P = .005). In addition, a significant association was found between the prevalence of sarcopenia and sex (P = .009).Conclusion: This study indicates that uremic sarcopenia and dynapenia are prevalent in PD patients in Tehran, Iran. These conditions may contribute to physical disability, decreased the quality of life, increased morbidity, and a high mortality rate. Therefore, prevention and treatment of uremic sarcopenia and dynapenia are necessary for Iranian PD patients.
