我国2002年代谢综合征的流行情况

Adults prevalence of metabolic syndrome in China in 2002

目的了解我国代谢综合征(MS)的流行现状。方法采用多阶段分层整群抽样方法于2002年8～10月和9～12月在全国31个省、直辖市、自治区的132个调查点中选取71971户居民进行调查。测量调查对象的身高、体重、腰围和血压,测定空腹血糖、血总胆固醇、甘油三脂、高密度脂蛋白胆固醇和低密度脂蛋白胆固醇。完成全部指标测定的总人数为48556人。结果根据中华医学会糖尿病学分会2004年MS的诊断标准,我国18岁以上人群MS的患病率为6·6%。我国城市各年龄组MS的患病率均高于农村,年龄调整后城市男性的患病率约为农村的两倍,女性约为农村的1·4倍。有糖代谢异常的MS男性为44·8%,女性为47·8%;有血脂异常的MS男性为86·3%,女性为83·4%;有高血压的男性为89·2%,女性为91·0%。符合MS诊断标准的人群男性95·2%有超重和肥胖,女性93·1%有超重和肥胖。结论我国18岁以上的人群MS的患病率为6·6%,其中男性为6·8%,女性为6·4%。城市的患病率高于农村。超重和肥胖是MS的最重要的危险因素。

Objective To estimate the prevalence of metabolic syndrome （MS） in China. Methods The 71 971 households of population from 31 provinces, autonomous regions, and municipalities were chosen by multi-steps cluster sampling during Aug.-Oct. and Sep.-Dec. , 2002. The physical examinations included measurement of height, weight, waist circumference and blood pressure. Laboratory tests included fasting blood glucose, total cholesterol, triglyceride, HDL-C and LDL-C. The 48 556 subjects participated in all health examinations. Results The prevalence rate of the MS among adults over 18 years old was 6.6% according to the criteria of Chinese Association of Diabetes. The rate was two times higher in men, and 1.4 times in women in urban than in rural areas. The proportion of MS with hyperglycemia to the total MS was 44.8% in men and 47.8% in women; with dyslipidemia was about 80% in men and 83.4% in women;and with hypertension was 89.2% in men,and 91.0% in women. Among individuals with metabolic syndrome 95.2% were overweight or obesity in men and 93.1% in women. Conclusions The prevalence rate of the metabolic syndrome among adults over 18 years old is 6.6%, with 6.8% in men and 6.4% in women in China. There is a big difference in the prevalence rate of metabolic syndrome between urban and rural areas, the rate is higher in urban areas. Overweight and obesity are the most important risk factors for metabolic syndrome.
