唐山地区44～64岁城乡居民代谢综合征患病率调查

目的了解唐山地区人群代谢综合征（Ms）的患病状况，并对城市和农村居民MS患病率进行比较。方法采用随机整群抽样方法，于2009年3—4月选取唐山地区44～64岁，平均年龄（54．2~6．9）岁城乡居民共6616人（男2286人，女4330人）进行问卷调查、体格检查及相关代谢指标的测定，采用中华医学会糖尿病学分会诊断标准进行MS筛查。结果唐山市44～64岁居民MS粗患病率、男性及女性粗患病率分别为20．9％，19．5％和21．7％，标化患病率分别为20_3％，19．2％和21．1％。女性MS患病率随年龄的增长而升高（P〈0．叭），从44～49岁的12．4％增加到60～64岁的30．5％，而男性MS患病率在年龄水平上差异无显著性；城市居民MS患病率（27．8％）高于农村（18．3％，P〈0．01），农村居民中男性MS患病率（16．7％）低于女性（19．3％，P〈0.05）。MS各组分的检出率依次为超重肥胖（61．4％）、高血压（51．3％）、高三酰甘油（36．6％1和空腹血糖升高（29．0％）。结论唐山地区44—64岁城乡居民标化患病率为20．3％，城市居民MS患病率显著高于农村，超重肥胖和高血压是该地区MS最重要的组成成分。

The Prevalence of Metabolic Syndrome among Urban and Rural Residents aged 44-64 years in Tangshan City

Objective To estimate the prevalence of metabolic syndrome （MS） in Tangshan district, and to compare the differences between the urban and rural population. Methods From March to April of 2009, a total of 6 616 subjects （2 286 men and 4 330 women） aged between 44 and 64 years [average age of （54.2±6.9） years] in Tangshan were selected using eluster randomly sampling. Physical examination and questionnaire were taken and fasting plasma glucose （FPG） and triglycerides （TG） were measured. The criterion of China Diabetes Society （CDS） in 2004 was applied for MS diagnosis. Results The crude prevalence of MS were 20.9% in total subjects, and 19.5%in male, 21.7% in female, respectively, while the standardized rates were 20.3%, 19.2%, 21.1%, respectively. In female, the prevalence increased from 12.4% among the 44-49 age group to 30.5% among the 60-64 age groups. However, the prevalence rate of MS in male was not significantly different between age groups. The prevalence of MS in urban （27.8%） was higher than that in rural population （ 18.3%, P〈0.01 ）. The detection rates of components of MS were 61.4% for overweight/obesity （BMI≥25 kg/m2）, 51.3% for hypertension （≥ 140/90 mm Hg）, 36.6% for hypertriglyceridemia, and 29.0% for abnormal fasting plasma glucose. Conclusion The overall standardized rate of MS was 20.3%, and it was higher in urban than in rural populations. In this study, overweight/obesity and hypertension were the major components of MS.
