6～24月龄婴幼儿喂养指数分布以及与生长发育的相关性研究

Distribution of feeding index and association between feeding index and growth of infants and young child aged 6-24 months

目的利用2002年全国营养和健康状况调查数据建立我国婴幼儿喂养指数,评价喂养情况与生长发育的关系。方法依据世界卫生组织推荐喂养方式,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年龄别体重(WAZ)、年龄别身长(HAZ)和身长别体重(WHZ)关系。结果城乡婴幼儿喂养指数评分存在显著差异(P<0.001),随着婴幼儿月龄的增加,喂养指数评分显著增加(P<0.05),喂养指数得分与WAZ、HAZ和WHZ显著相关(P<0.05)。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 Data from the Nutrition and Health Survey of the Chinese People on 2002 were use to explore the feasibility of creating a composite feeding index and examine the association between feeding practices and growth of infants and young child. Methods The variables used for index were as follows： current breast-feeding, introduction of complementary foods, the past month and feeding frequency. The index was made age specific for 6- to 9-,9- to 12- and 12-to 24-month-old age groups, age-specific feeding terciles were created to evaluate the association between feeding index and growth. Results the socres of feeding practice were different significantly between urban and rural. Bivariate analyses showed that feeding practices were strongly and significantly associated with child growth in china, especially with increasing age, the scores of feeding practices were increasing. Conclusion The present study showed that better feeding practices were more important for children of lower socioeconomic status, The data available in CNHS data can be used effectively to create a composite child feeding index which could be targeted by nutrition education and behavior change interventions.
