objective to explore environment risk factors of metabolic syndrome.methods a cross-sectional population survey with questionnaires investigation,checkup and laboratory measurement for metabolic syndrome was performed among 2026 teachers,and the logistic regression was used to analyze the risk factors of ms.results the education,milk intakes,fish and aquatic products intakes,body exercise and drinking tea were different significantly between male and female individuals.univariate unconditional logistic regression analysis showed that education,body exercises,fish and aquatic products intakes and drinking tea were benefited to the ms,but the age,sucrose intakes were the risk factors to the ms.the multivariate logistic stepwise regression analysis showed that compared with individuals with no drinking milk,or no fish and aquatic product intake,or no drinking tea,or no sucrose intakes,the milk intakes 250-1500 g/week(or=0.731,95%ci:0.542-0.987),the fish and aquatic product intake with 250-1000 g/week(or=0.720,95%ci: 0.541-0.959),or sucrose intakes 250 g/month(or=0.446,95%ci:0.255-0.779),drinking tea forepassed(or=0.635,95%ci:0.458-0.883),and current (or=2.084,95%ci:1.390-3.125) had different levels of risk on ms.conclusion the age and sucrose intakes are risk factors,and the milk intakes,aquatic products and drinking tea benefits for ms.

目的 了解中小学教师代谢综合征发病及其影响因素。方法采用横断面调查方法，随机抽取芜湖市中小学教师2 026名，进行问卷调查、体格检查和实验室检测，并运用logistic回归分析代谢综合征影响因素。结果不同性别的中小学教师在受教育程度、牛奶摄入、水产品摄入和饮茶习惯等方面的差异有统计学意义；其中受教育程度、体育锻炼、水产品摄入和饮茶是保护因素，而年龄、工作紧张程度、糖的摄入可能是代谢综合征的危险因素。logistic逐步回归分析结果提示，牛奶摄入、水产品摄入和饮茶是代谢综合征的保护因素，而年龄和糖摄入是代谢综合征的危险因素，其中牛奶摄入在250～1500 g/周(or=0.731，95% ci=0.542～0.987)，水产品摄入在250～1000 g/周(or=0.720，95% ci=0.541～0.959)以及以前饮茶（or=0.446，95% ci=0.255～0.779和现在正在饮茶(or=0.635，95% ci=0.458～0.883)，对代谢综合征的保护作用明显，而糖摄入250 g/月时代谢综合征的患病的危险是不食用食糖的2倍(or=2.084，95% ci=1.390～3.125)。结论年龄和糖摄入是代谢综合征患病的危险因素，而牛奶、水产品和饮茶是代谢综合征的保护因素。
