北京城区60岁以上居民腰围与代谢综合征的相关性研究

采用整群随机抽样的方法对北京市3个城区7594名老年人进行体检及空腹血液检查。按照2007年中国成人血脂异常防治指南的修订标准,代谢综合征（MS）的患病率为26．57％（2018／7594）,中心性肥胖的患病率为42．04％（3193／7594）。以腰围为自变量,MS患病率为应变量,建立中心性肥胖-代谢综合征的回归模型,当腰围高于切点时,腰围每减少3．3cm,MS患病率随之减少约4．5％。中心性肥胖是预防和治疗MS的主要靶点。

Relationship between waist circumference and prevalence of metabolic syndrome in Beijing elderly residents

Total 7594 elderly subjects from three urban districts in Beijing were enrolled in the study with randomized cluster sampling design. Physical examination and fasting plasma glucose test were undertaken for all participants. Based on the diagnosis criteria from The Guidelines of Dyslipidemia Control fi~r Chinese Adults in 2007, the prevalence of metabolic syndrome （MS） was 26. 57% （2018/7594） and the prevalence of central obesity was 42.04% （3193/7594）. Using waist circumference （WC） as independent variable and MS prevalence as dependant variable, we developed a ＂Central obesity-Metabolic Syndrome＂ multiple regression model. The results showed that among those having WC higher than cutoff point, with each 3.3 em reduction of WC, the prevalence of MS decreased by 4. 5%. Therefore, central obesity can be used an important clinical target of MS for both prevention and treatment purposes.
