ABSTRACT
Objective:To explore the prevalence rate of restless leg syndrome (RLS) and its related influencing factors in patients with maintenance hemodialysis (MHD) in Anhui province.Methods:It was a cross-sectional study, including regular MHD patients in blood purification centers of 27 hospitals in southern, central and northern Anhui province from January to March 2020. The investigation included general demographic characteristics, primary diseases, complications, dialysis-related conditions and drug use. According to the presence or absence of RLS, the patients were divided into RLS group and non-RLS group, and the differences of clinical data between the two groups were compared. Logistic regression analysis method was used to analyze the influencing factors of RLS.Results:The study included 3 025 MHD patients, aged (54.8±12.8) years old, with 1 819 males (60.1%) and 1 206 females (39.9%). The dialysis age was (5.5±3.8) years. The prevalence rates of RLS in MHD patients were 8.8% (265/3 025), of which 13.7% (77/561), 7.7% (88/1 145) and 7.6% (100/1 319) in southern, central and northern Anhui province, respectively. The prevalence rates of RLS in MHD patients in secondary and tertiary hospitals were 9.5% (55/577) and 8.6% (210/2 448), respectively. Proportion of hypertension, dialysis age, intact parathyroid hormone, alkaline phosphatase, 25(OH)D3, and proportions of secondary hyperparathyroidism, erythropoietin use, iron supplements, active vitamin D use, calcimimetic use, dialysis blood flow <250 ml/min and low-flux dialyzers in RLS group were higher than those in non-RLS group, while hemoglobin level and proportions of non-calcium-phosphorus binders and high-flux dialyzers were lower than those in non-RLS group (all P<0.05). Multivariate logistic regression analysis results showed that long dialysis age ( OR=1.188, 95% CI 1.031-1.369, P=0.017) and high alkaline phosphatase ( OR=1.007, 95% CI 1.001-1.013, P=0.047) were correlated with a higher risk of RLS in MHD patients. Conclusions:The prevalence rate of RLS in MHD patients in Anhui province is 8.8%. The prevalence rates of RLS in MHD patients in southern, central and northern Anhui province are 13.7%, 7.7% and 7.6%, respectively. The prevalence rate of RLS in secondary and tertiary hospitals are 9.5% and 8.6%, respectively. Long dialysis age and high alkaline phosphatase are associated with a high risk of RLS in MHD patients.
