中国儿童营养状况15年变化分析——中国婴幼儿辅食喂养的改善

目的利用中国食物与营养监测数据,描述1992~2005年中国婴幼儿喂养的改善情况。方法以各种辅助食品开始添加的时间和添加频率描述了我国婴幼儿辅助喂养的改善。以logistic回归方法分析了中国儿童各种辅食添加时间和添加频率与生长发育的关系。结果1992年~2005中国婴幼儿,特别是农村婴幼儿辅食喂养的模式有了很大的改善。婴儿6个月龄按时添加奶及其制品、蔬菜/水果、动物性食品与婴幼儿生长迟缓率、低体重率呈负相关。没有按时添加奶及其制品对婴幼儿生长迟缓的相对危险度为1.378,对低体重的相对危险度1.189。每天添加牛奶,动物性食物,蔬菜水果对婴幼儿身高增长和体重增长有非常重要的作用。结论15年来中国儿童生长发育的改善,与农民收入增加后婴幼儿辅助喂养的改善有关。

Analysis on the changes of nutritional status in China——the improvement of complementary feeding among Chinese infants and young children

Objective To describe the improvement of complementary feeding during year 1992 to 2005. Method The datasets of 1992, 2000 and 2005 China Food and Nutrition Surveillance System (CFNSS) were used, the improvement of complementary feeding were presented in terms of timely introduction, and frequency of food items in complementary feeding, Logistic Regression Analysis on the relationship of child growth with complementary feeding pattern were conducted. Results The complementary feeding of Chinese children improved substantially during year 1992 to 2005. The appearance of animal food, vegetable/fruit and milk in complementary feeding was negatively correlated with the prevalence of stunting and underweight. OR of non-milk complementary food for stunting at age 9-24 month was 1.378, to underweight, the OR was 1.189. The results of multiple regression analysis proved the frequency of feeding vegetable/fruit, animal food and milk played essential role in child growth during 6-24 month of age.Conclusion The improvement of complementary feeding contributed substantially to the improvement of child growth in past decade in China.
