Survey and analysis on the dietary patterns and nutriture of urban women in four cities including Beijing

目的 :进一步深入研究不同城市妇女膳食结构及营养状况。方法 :按食物复制法要求被调查对象收集 2 4h摄取的食物 ,以中国的食物成分表为计算依据 ,用 2 0 0 0年修订的“推荐营养素摄入量 (RNI)”作为评价指标。结果 :四城市妇女膳食热量摄入量约占RNI的 80 % ;蛋白质的摄入量以上海市最低 ,仅占RNI的71% ,其它三城市均接近RNI;四城市妇女膳食钙的摄入量约占RNI的 5 0 % ;维生素摄入量除维生素E比较充足外 ,视黄醇当量、维生素B1、维生素B2 和维生素C的摄入量与RNI比较均偏低。结论 :对于钙和各种维生素的缺乏 ,应调整膳食结构加以改善。

Objective: To investigate the dietary patterns and the nutriture of urban women. Methods: Dietary survey was conducted by Food duplication. The intake of nutrients was calculated in line with the Chinese Food Composition Table and evaluated with the Recommended Nutrients Intake(RNI) modified in 2000. Results: The energy intake per women per day in every city accounted for 80% of the RNI. The protein intake of women in Shanghai was the lowest, only accounting for 71% of the RNI, but protein intake of women in other cities nearly meets the standard of RNI. The calcium intake of all women is rather poor, being only about 50% of the RNI. In comparison with the RNI, the intake of vitamins including RE, VitB 1, VitB 2 and VitC was low with VE being an exception. Conclusion: In order to increase the intake of calcium and vitamins, it is necessary to improve the dietary patterns in urban women.
