锡林浩特市城镇居民代谢综合征流行病学调查

Study on prevalence of metabolic syndrome among urban population in Xilinhaote,Inner Mongolia

目的了解内蒙古自治区锡林浩特市城镇居民代谢综合征(MS)及其各组分疾病的流行现状。方法对在锡林郭勒盟医院体检的20岁以上城镇居民1060人进行流行病学调查。利用2005年国际糖尿病联盟(IDF)的MS定义进行资料分析。结果(1)锡林浩特市城镇居民MS粗患病率为29.2%,年龄标化患病率为25.0%,男性高于女性(P<0.05),中心性肥胖、高血压、高血糖、高甘油三酯(TG)血症、低高密度脂蛋白胆固醇(HDL-C)血症年龄标化患病率分别为39.5%,53.1%,23.8%,38.8%,0.2%,除低HDL-C血症外,MS各组分的患病率男性均高于女性(P<0.05)。(2)男性MS及中心性肥胖、高血糖、高TG血症患病率30～50岁组均处于较高水平,60岁以后有所下降。女性MS及其各组分患病率均随着年龄的增加而增加,50岁以后增加明显。(3)蒙古族MS患病率高于汉族。(4)77.7%的个体具有1种及以上的MS组分疾病,完全正常的个体仅占22.3%。(5)MS最常见的表现形式为中心性肥胖+高血压+高TG血症,占MS总患病率的46.6%。结论锡林浩特市城镇居民MS及其各组分疾病的患病情况严重,应采取适当的干预措施,控制MS流行,降低心脑血管疾病风险。

Objective To estimate the prevalence of metabolic syndrome（MS） and its components among the urban population in Xilinhaote, Inner Mongolia. Methods Epidemiology investigation was carried out among 1060 residents who took their health .examination in Xilinhaote hospital during September 2006 to March 2007. MS and its components was diagnosed according to the definition proposed by IDF in 2005. Results The crude prevalence of MS in the subjects was 29.2 %, and age - adjusted prevalence was 25.0 %, with higher rate in men than in women（ P 〈 0.05）. The aged - adjusted prevalence of central obesity, high blood pressure, high blood glucose, hypertriglyceridaemia and low HDL cholesterol was 39.5 %, 53.1%, 23.8 %, 38.8 % and 0.2 % respectively, with higher rates in men than in women except low HDL cholesterol（P 〈 0.05）. The prevalences of MS, central obesity, high blood glucose and hypertriglyceridaemia were in a high level in the subjects of 30 to 50 years old, and showed a mild decrease after 60. The prevalence of MS and its components in women increased with age, especially after 50 years old. The prevalence of MS in Mongolian nationality was higher than in Han nationality. About 77.7 % of the subjects had ≥1 metabolic disorder factors, and only 22.3 % were completely normal. The most common combination of MS was central obesity, high blood pressure and hypertriglyceridaemia. Conclusion The prevalence of MS and its components are high in Xilinhaote population. We should take appropriate measures to control the prevalence of MS.
