Analysis on risk factors for metabolic syndrome in patients with maintaining hemodialysis
2011
Objective To investigate prevalence of metabolic syndrome (MS) and its related factors in patients with maintaining hemodialysis (MHD). Methods A total of 162 cases on MHD in Beijing Chaoyang Hospital during June to December 2010, were enrolled in this study and divided into MS group and non-MS group according to the diagnostic criteria for MS set by the International Diabetes Federation. Anthropometric and blood biochemical characteristics of the two groups were compared with t-test and x2 test Risk factors for MS were explored with binary logistic regression analysis. Results Prevalence of MS was 40. 7% (66/162) . There was significant difference found in body mass index [(24. 2 ±3. 1) vs. (21. 6 ±2. 7) kg/m2], waistline circumference[(93 ±8) vs. (79 ±7)cm] , white blood cell count [(6. 8 ± 1. 5) × 109/L vs. (5. 6 ± 1. 4) × 109/L] , hypersensitive serum C-reactive protein [(7 ± 5)vs. (4 ±3) mg/L], high-density lipoprotein-cholesterol [(0. 99 ±0. 26)vs. (1.39 ±0.39) mmol/L], low-density lipoprotein-cholesterol [(2. 5 ± 0. 8) vs. ( 2. 1 ± 0. 7) mmol/L], triglyceride ( TG) [( 2. 1 ±1.1 )vs. (1.3±0.8) mmol/L], fasting blood glucose [(5.9±2. 7)vs. (4.8±1.3) mmol/L], serum level of iron [(16±7)vs. (13 ±5) μmol/L], uric acid [(429±114) vs. (388±88) (μmol/L], and carbon dioxide combining power (CO2CP) [(22 ±4)vs. (23 ±4) mmol/L]between MS group and non-MS group (All P 0.05). Binary logistic regressive analysis revealed that serum level of iron (OR = 1.058,95% CI = 1.001 -1. 119), white blood cell count ( OR = 1. 786,95% CI = 1. 346 - 2.371) and hypersensitive serum C-reactive protein (OR = 1. 101,95% CI = 1.010 - 1.201 ) were independent risk factors for MS in MHD patients. Conclusions Morbidity of MS is high in patients with MHD, involved with inflammation process. Serum level of iron, white blood cell count and hypersensitive serum C-reactive protein are independent risk factors for MS in patients with MHD and no inevitable connection between MS and nutritional status in them is found.
