血尿酸对代谢综合征的预测作用研究

目的 探讨体检人群血尿酸(SUA)水平与代谢综合征(MS)及其因素的相互关系.方法 抽样选择2013年在某院体检者8 285例,进行体格测量和生化检查;根据MS诊断标准、性别、血高尿酸血症(HUA)水平进行分组,分析SUA水平与MS的相关性.结果 MS患者的年龄、BMI、收缩压(SBP)、舒张压(DBP)、空腹血糖(FPG)、三酰甘油(TG)和SUA明显高于非MS患者,而高密度脂蛋白胆固醇(HDL-C)明显低于非MS组.男性MS发病率高于女性.随着MS因素的增加,SUA水平总体呈升高趋势;多元逐步回归分析,BMI、DBP、TG与SUA呈正相关,HDLC与SUA呈负相关,回归方程为Y=-2.135+0,066X1+0.010X2+0.155X3-0.379X4;HUA患者MS检出率高于非HUA患者;单因素Logistic回归分析,SUA水平与MS的发生明显相关(OR=1.007,95％CI 0.006～1.007,P＜0.05),SUA对MS的诊断价值,男女性曲线下面积(AUC)分别为0.608(95％CI 0.582～0.634,P＜0.0t)、0.744(95％CI 0.705～0.783,P＜0.01),MS最佳临界诊断点分别为360.5、256.5,相对应的诊断灵敏度为46.49％、71.94％,特异度为69.94％、67.24％.结论 SUA水平与MS及其因素关系密切,SUA对MS预测作用较好.

Predictive research on serum uric acid to metabolic syndrome

Objective To explore the mutual relationship between serum uric acid (SUA) level with metabolic syndrome (MD) and its factors among the physical examination population.Methods A total of 8 285 people undergoing the physical check-up in a hospital in 2013 were selected by sampling and conducted the physical measurement and biochemical detection;the subjects were grouped according to the MS diagnostic standard,gender and SUA.Then the correlation between SUA and MS was analyzed.Results The age,BMI,SBP,DBP,FPG,TG and SUA in the MS patients were significantly higher than those in the patients without MS,while the HDL-C level was significantly lower.The occurrence rate of MS in males was higher than females.With the increase of MS factors,the SUA level showed the overall rising trend;the multiple stepwise regression analysis indicated that BMI,DBP and TG were positively correlated with SUA,and the HDL-C level was negatively correlated with the SUA level.The regression equation was Y =-2.135 + 0.066X1 +0.010X2 +0.155X3-0.379X4;the MS detection rate in the HUA group was higher than that in the non-HUA group;in the single factor Logistic regression analysis,the SUA level was significantly related with the MS occurrence (OR=1.007,95％CI 0.006-1.007,P＜0.05),in the SUA diagnostic value for M,AUC in male and female were 0.608 (95 ％CI 0.582-0.634,P＜0.01) and 0.744 (95 ％CI 0.705-0.783,P＜0.01) respectively,the MS best critical diagnostic points in male and female were 360.5 and 256.5,the corresponding diagnostic sensitivities in male and female were 46.49％ and 71.94％,the specificities in male and female were 69.94％ and 69.94％ respectively.Conclusion The SUA level is closely associated with MS,and SUA level has a good predictive effect for MS.
