ABSTRACT
Objective Sarcopenia and metabolic syndrome share similar pathophysiological mechanisms. The aim of this study was to investigate the prevalence of sarcopenia among health examination population, and to analyze the relationship between sar-copenia and blood pressure, blood glucose, uric acid and lipids. Methods Physical examination data of 1191 healthy persons in the medical examination center of the hospital from Mar 2011 to Jun 2011 were collected. The weight, skeletal muscle, body fat, body mass index ( BMI) , waist circumference,body fat percentage, waist-hip ratio and visceral fat area were analyzed by human body compositionanalyzer and the prevalence of sarcopenia was observed. At the same time, triglyceride (TG), total cholesterol (TC), high density lipo-protein-cholesterol ( HDL-C ) , low density lipoprotein-cholesterol ( LDL-C) , uric acid and fasting blood glucose were also detected. Results The prevalence rate of sarcopenia of the subjects was 5.21%, and the highest incidence was found in ≥60 years group( 11.11%) . The prevalence rates of overweight and obesity were 33.8% and 10.2%, respectively. The prevalence of sarcopenia is grad-ually higher along with increasing BMI. The prevalence rates of sarcopenia of overweight and obesity subjects were 5.47% and 26.23%, respectively. Compared with the normal control group, the level of weight[(66.34±11.75)kg vs (76.71±12.84)kg ], BMI[(23.37± 3.13) vs (28.05±3.66)], body fat percentage[(25.33±6.06)% vs (36.76±4.47)%], waist circumference[(83.19±9.56)cm vs (95.45±13.74)cm] and visceral fat area[(88.96±29.74)cm2 vs (136.91±25.56)cm2] were higher in the sarcopenia group (P<0.05). Compared with the normal control group, the incidence of systolic blood pressure[(125.59±30.04)mmHg vs (139.39±19.79) mmHg], diastolic blood pressure[(75.82±11.95)mmHg vs (82.34±10.96)mmHg ] TG[(1.56±1.12)mmol/L vs (1.98±1.72)mmol/L] and uric acid[(313.75±83.07)mmol/L vs (335.55±96.07)mmol/L] were higher in the sarcopenia group (P<0.05). Compared with the normal subjects, the detectable rates of abnormal diastolic blood pressure, fasting blood glucose, uric acid, and LDL-C were increased in the sarcopenia, obesity and sarcopenia combined with obesity subjects (P<0.05). The odds ratio of abnormal systolic blood pressure, diastolic blood pressure, uric acid, and LDL-C increased in the sarcopenia, obesity and sarcopenia combined with obe-sity subjects using logistic regression analyses after correction of gender and age. Conclusion The sarcopenia may have some con-nection with metabolic risk factors. Early detection of sarcopenia can help to distinguish people predisposed to metabolic syndrome, and it has important significance for prevention of chronic disease.
ABSTRACT
Objectives:To study the relationship between nutrition status and renal function in renal disease patients. Methods: Body weight, height and the outcomes of blood biochemistry and routine were analyzed in 110 renal patients. Results: Body weight distribution in renal failure group had marked difference compared with nomal renal function group, and the number of patients whose actual body weight being lower than ideal body weight was obviously increased. The levels of RBC, Hb and TLC were significantly decreased(P
