Introduction: This study was conducted to determine the factors affecting the development of sarcopenias in elderly patients with chronic kidney disease (CKD), in order to provide future clinical reference and guidance in preventing the occurrence of sarcopenias in patients with CKD.
Methods: We included 116 CKD patients admitted to affiliated Hospital of Hebei University for retrospective analysis between September 2019 and March 2022. Fifty-one CKD patients with sarcopenias were selected as the observation group (OG) and 65 CKD patients without sarcopenias were considered as the control group (CG). Clinical baseline data such as age and sex were recorded, venous blood was collected for routine examination, and a multi-frequency body composition analyzer was applied to measure patients' body composition. Grip strength, middle arm circumstances (MAC) and triceps skin-fold thickness (TSF) were also measured. Then, patients' sleep quality, nutritional status and negative psychological status were assessed by using the Pittsburgh Sleep Quality Index (PSQI), Malnutrition inflammation score (MIS), and Self-rating Anxiety/Depression Scale (SAS/SDS), respectively. Differences in test results were compared inter-group, and the factors affecting the occurrence of sarcopenias in CKD patients were analyzed by multiple Logistic regression.
Results: OG patients were older than CG patients, with a higher number of female patients. Their BMI, bone mass, MAC, serum creatinine (Scr), uric acid (UA) and triglyceride (TG) were lower (P < .05). According to multiple Logistic regression analysis, age, as well as PSQI, MIS, SAS, and SDS scores were the risk factors for sarcopenias in CKD, while BMI, bone mass, MAC, Scr, UA and TG were protective factors (P < .05).
Conclusion: Age, poor sleep quality, poor nutritional status and negative emotions are independent risk factors for sarcopenias in CKD patients, while BMI, bone mass, MAC, UA, TG, and Scr are independent protective factors. DOI: 10.52547/ijkd.7537.
