目的以2002年中国居民营养与健康状况调查的数据为研究背景,目的在于建立婴幼儿喂养指数,评价喂养情况与生长发育的关系。方法依据WHO推荐喂养方式,选择母乳喂养、是否用奶瓶喂养、膳食多样性、食物频率等变量,建立喂养指数评分体系,评价喂养指数评分与WAZ、HAZ和WHZ关系。结果不同地区喂养指数分布不同,大城市婴幼儿喂养指数显著高于其他地区(P<0.05),1岁后幼儿喂养指数评分显著高于6个月龄组的婴儿(P<0.05),随着婴幼儿月龄的增加,喂养指数增加,喂养指数与WAZ、HAZ、WHZ相关。结论喂养指数可以作为一项综合判断婴幼儿喂养的方法。
Objective To investigate the data of the survey on nutrition and health of Chinese residents in 2002 for the purpose of establishing infant feeding index and evaluating the relationship between feeding status and growth and development. Methods According to WHO recommended feeding mode, choose breastfeeding, whether to use bottle feeding, dietary diversity, food frequency and other variables to establish a feeding index scoring system to evaluate the relationship between feeding index score and WAZ, HAZ and WHZ. Results The distribution of feeding index was different in different regions. The index of infant feeding in big cities was significantly higher than that in other regions (P <0.05). After 1 year of age, the index of infant feeding index was significantly higher than that of infants in 6 months (P <0.05) The age of infants and young children increased, feeding index increased, feeding index and WAZ, HAZ, WHZ related. Conclusion Feeding index can be used as a comprehensive method for judging infant feeding.
