【摘要】 目的分析杭州市中年人群三种膳食模式与代谢综合征(MS)的关系,为预防MS提供依据。方法纳入2016年7月—2017年10月杭州市某三甲医院体检中心45~59岁健康体检人群,进行膳食调查、体格检查和生化指标检测,采用因子分析法构建膳食模式,采用Logistic回归模型分析膳食模式与MS的关系。结果共调查2 102人,回收有效问卷1 918份,问卷有效率为91.25%。检出MS患者453例,患病率为23.62%。因子分析获得三种膳食模式:动物型模式,摄入较多的畜禽肉、加工肉制品和蛋等;中国传统型模式,摄入较多的粮谷、新鲜蔬果、豆及豆制品和茶等;海产品型模式,摄入较多的海带/紫菜、咸鱼肉和鱼虾等。Logistic回归分析结果显示,调整性别、年龄、吸烟和体力活动等混杂因素后,动物型模式增加MS的患病风险(OR=1.224, 95%CI:1.072~1.944),中国传统型模式降低MS的患病风险(OR=0.785, 95%CI:0.477~0.998),海产品型模式与MS的患病风险未见统计学关联(P>0.05)。结论膳食模式与中年人群MS关系密切,坚持中国传统型膳食模式,减少肉类食物摄入有助于降低MS的患病风险。更多还原

【Abstract】 Objective To analyze the association between three dietary patterns and metabolic syndrome( MS) in a middle-aged population and to provide basis for MS prevention. Methods Subjects aged 45-59 years at the physical examination center of a top three hospital in Hangzhou from July 2016 to October 2017 were invited for dietary survey,physical examination and biochemical detection. Factor analysis was used to construct the dietary pattern. The logistic regression model was used to analyze the association between dietary patterns and the risk of MS. Results A total of 2 102 subjects were investigated, 1 918 valid questionnaires were returned, and the effective rate reached 91.25%. There were 453 patients with MS, and the prevalence was 23.62%. Three dietary patterns were identified: animal pattern with high intake of livestock/poultry meat, processed meat products, eggs, etc; traditional Chinese pattern with high intake of cereal grains,fresh fruits and vegetables, beans and soy products, tea, etc; seafood pattern with high intake of seaweed/kelp, salted fish/meat, fish, shrimp, etc. After adjusting for gender, age, smoking and physical activity, logistic regression analysis indicated that the animal pattern might increase the risk of MS(OR=1.224, 95%CI: 1.072-1.944), the traditional Chinese pattern might reduce the risk of MS(OR=0.785, 95%CI: 0.477-0.998), but there was no association between the seafood pattern and the risk of MS( P >0.05). Conclusion The dietary patterns are closely related to MS in a middle-aged population. Adhering to traditional Chinese dietary pattern and reducing the intake of meat can reduce the risk of MS.更多还原
