中国7省市城市居民膳食结构的动态综合分析

Dynamic and comprehensive analysis of dietary patterns for urban population in 7 provinces in China

通过对１９９０年８７５０户及１９９２年２２０３户７省市城市居民膳食结构的动态综合分析，指出收入总体水平在增加，而极差在拉大；ＤＤＰ评分亦增加，但省间差距在缩小。浙江城市居民的ＤＤＰ评分为９８．７分，营养素摄入均达中国ＲＤＡ的９０％以上，故推荐＂浙江模式＂以供其他省借鉴。７省市９０年代尚无ＤＤＰ扣分，到１９９２年４省动物性食物消费过量，７省食用油脂过量，故给予扣分，其对策是适量消费动物性食物，并提倡吃鱼、奶、禽肉以调整动物性食物的消费结构，还引入价格弹性、供求平衡等经济学分析，阐明减少油脂消费的关键不在市场调节，而在营养宣教的观点。

From 1990 to 1992 income of urban population in 7 provinces in China increased , and the variation of income in the 7 provinces also increased. The DDP scores of people increased, while the variation decreased. The DDP score of urban population of Zhejiang in 1992 was 98.7, the best in the 7 provinces and the nutrients intake reached over 90 percent of the Chinese RDA. Thus, Zhejiang pattern is recommended. There was no DDP penalty score in 1990, while in 1992, animal foods, oils and fats have DDP penalty scores due to over consumption. The strategies are to enhance nutrition education to make people consume appropriate amounts of animal foods, eat more fish, milk or poultry instead of pork.
