上海城镇居民在外就餐膳食结构对肥胖症发病的影响

为了解城镇居民在外就餐的膳食结构及其对肥胖症发病的影响,指导长期在外就餐居民合理选择食物并为肥胖人群的干预策略提供依据。采取整群抽样法抽取18～74岁的上海城镇居民,测量并计算BMI值,判断超重及肥胖发病情况,同时对调查对象进行问卷调查,通过半定量膳食频度法分析其在外就餐的膳食结构,通过SPSS进行logistic回归及线性回归,分析在外就餐膳食结构与肥胖症发病的相关性。结果显示,在外就餐的膳食结构为高脂肪、高胆固醇、低碳水化合物、低膳食纤维,且回归分析表明胆固醇及饮料的摄入是肥胖症的危害因素。可见在外就餐膳食结构存在不合理,长期在外就餐会增加肥胖症发病风险,长期在外就餐者应合理选择食物,平衡膳食结构。

Influence of Dietary Structure on Obesity in Shanghai Urban Citizens Who Frequently Dine Out

To investigate the dietary structure of eating out and its effect on obesity,and then help long-term dining out residents select food reasonably and provide evidence for intervention strategies,cluster sampling was used to select participants aged 18to 74.BMI was used to assess overweight and obesity.Dietary structure of dining out was analyzed by semi-quantitative food frequency questionnaire.Logistic regression and linear regression were used to analyze the relationship between dietary patterns of dining out and obesity.Results showed that dietary structure of dining out is high protein,high fat,high cholesterol,low carbohydrate and low dietary fiber.Regression analysis showed that intake of cholesterol and beverage was the risk factors of obesity.So dietary structure of dining out is unreasonable,and long-term dining out increases obesity risk.We should choose food reasonably and keep a balanced diet structure.
