老年男性腰围与代谢综合征的调查分析

An investigation and analysis on metabolic syndrome and obesity among older males

目的探讨老年男性腰围与代谢综合征（MS）之间的相关性，分析代谢综合征的危险因素，对积极开展早期防治工作提供参考依据。方法以2005年国际糖尿病联盟（IDV）制订的代谢综合征全球共识作为标准，对1700例60岁及以上的老年男性进行了调查，按照腰围进行分层，分析不同腰围人群代谢综合征的患病率及各项代谢指标的异常情况。结果本组腰围≥90cm患者占36．41％，中心性肥胖为63．58％，高血压为59．35％，血糖异常为40．76％，高甘油三酯血症为33．88％；92．57％的患者有不同程度的代谢异常，合并2种及以上代谢异常者占71．05％；当腰围≥90cm时，代谢综合征的患病率随腰围的增加而上升，腰围增加与代谢异常数量之间呈正相关（r=0．479，P〈0．01）；腰围的增加与体重指数、收缩压、舒张压、甘油三酯正相关，与高密度脂蛋白胆固醇之间呈负相关（r=-0．2702，P〈0．01）；腰围≥90cm组高血压的患病率明显高于腰围〈90cm组（P〈0．01）。结论老年男性腰围水平变化与代谢综合征的发生有相关性，代谢综合征的患病率和代谢指标异常数量随着腰围的增加而升高。

Objective To investigate the relationship between obesity and metabolic syndrome and identify risk factors for metabolic syndrome in older man in order to reference for nursing interventions. Methods A survey was conducted among 2,000 men aged 60 years and over. According to the working definition of International Diabetes Federation （IDF） in 2005, the morbidity of metabolic syndrome and epidemiological condition of some metabolic indexes was identified after grading waistline（WL）. Results The proportions of elder male people with WL over 90em, central obesity ,essential hypertension ,glucose metabolic disorder and hypertriglyceridemia were 36.41%, 63.58%, 59.35%, 40.76% and 33.88% respectively. 92.57% patients had metabolic disorders, and 71.05% complicated with two or more metabolic disorders. The morbidity of metabolic syndrome increased with the increasing of waistline, when waistline was beyond 90cm. There was positive correlation between the waistline and the number of abnormal metabolic indexes（ r =0. 479, P 〈0. 01 ）. WL had direct correlation with BMI, systolic blood pressure, diastolic blood pressure and triglyceride level （r = 0. 722,0. 125,0. 163 and 0. 284 respectively ） and had negative correlation with high density lipoprotein cholesterol （ r = - 0. 270 2 ）. The morbidity of hypertension in the group with waistline beyond 90cm was obviously higher than that group with waistline below 90cm （P 〈 0. 01 ）. Conclusions Waist circumference has correlation with metabolic syndrome in older men. While the waistline increased, the number of abnormal metabolic indexes and the morbiditv of metabolic svndrome increased.
