贵阳市城区某社区20岁及以上成人代谢综合征患病率调查

目的了解贵阳市城区成人代谢综合征（MS）的患病情况，并分析其影响因素。方法2009年11月至2010年2月，采用分层整群抽样方法调查贵阳市城区宅吉社区20岁及以上常住居民共1512人（男634人，女878人），分为6个年龄组（≥20—30、≥30～40、≥40～50、≥50—60、≥60～70、≥170岁），对其进行问卷调查、体格检查及相关代谢指标的测定。MS采用2005国际糖尿病联盟（IDF）全球共识定义。组间率的比较用χ2检验，均数的比较用t检验。结果调查人群中Ms的粗患病率为29．7％（男性26．5％，女性32．0％），女性高于男性（χ2=5．346，P〈0．05），标化患病率为29．1％（男性26．6％，女性31．6％）。MS的患病率随年龄的增长而显著升高，女性在≥60～70岁达到高峰，男性在≥140～50岁达到高峰。调查人群中中心性肥胖、甘油三酯升高、高密度脂蛋白胆固醇降低、血压升高及空腹血糖升高的粗患病率分别为39．5％、38．0％、49．1％、35．9％、55．2％，标化患病率分别为38．3％、39．4％、47．6％、36．1％、56．0％。调查人群中，1335名（88．3％）有一项以上代谢组分异常。MS患者中，有3、4及5项代谢组分异常者分别占43．2％、39．9％及16．9％。结论贵阳市城区宅吉社区成人MS的患病率较高，MS的防治工作应进一步加强。

Prevalence of metabolic syndrome among adults aged 20 years or above in Zhalji community inGuiyang urban areas

Objective To investigate the prevalence of metabolism syndrome （MS） among adults in Guiyang urban areas and analyze its influencing factors. Methods Total of 1512 inhabitants aged twenty years and above living in a community of Guiyang urban areas were investigated from November 2009 to February 2010 by adopting stratified cluster sampling method （634 males and 878 females）. The subjects were divided into six age groups （≥20 -30, ≥30 -40, ≥40 -50,≥150 -60, ≥60 -70 and ≥70 years）. Questionnaires, physical examinations and determination of related metabolic index were carried out in the subjects. MS was defined according to global consensus of International Diabetes Federation （IDF） in 2005. Comparison of rate between groups was analyzed by the X2 test, and comparison of mean values was statistically analyzed with t test. Results The crude prevalence of MS among the investigated population was 29.7%, and it was higher in females than that in males（32. 0% vs 26. 5%, X2 =5. 346, P 〈0.05）, and standardized MS prevalence was 29. 1% （26. 6% in male, 31.6% in female）. The prevalence of MS increased with the increase of age, and it reached peak at ≥ 60 - 70 and ≥40 - 50 years in females and males, respectively. The crude prevalence of central obesity, elevated triglycerides, reduced high-density lipoprotein cholesterol and increased blood pressure and fasting blood glucose among investigated population was 39. 5%, 38.0%, 49. 1%, 35.9% and 55. 2%, respectively; and the standardized prevalence of above-mentioned indexes was 38. 3%, 39. 4%, 47. 6%, 36. 1% and 56. 0%, respectively. In investigated population, 1335 （88.3%） had more than one metabolic component abnormality. Among MS patients,those who had 3, 4 and 5 metabolic component abnormalities accounted for 43.2%, 39. 9% and 16. 9%, respectively. Conclusions The prevalence of MS among adults in Zhaiji community of Guiyang urban areas is higher, so the prevention work of MS should be further strengthened.
