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。
