6～24月龄中国婴幼儿喂养指数评价方法的建立

目的建立6～24月龄中国婴幼儿喂养指数,为综合评价婴幼儿喂养提供有效的工具。方法以2002年Ruel和Menon提出的喂养指数概念为基础,根据世界卫生组织(WHO)喂养建议和中国0～6岁儿童膳食指南,建立喂养指数确定各变量分类及分值,利用四川、河北、黑龙江三地区城乡6～24月龄共1738名婴幼儿年龄别体重(WAZ)、年龄别身长(HAZ)和身长别体重(WHZ),分析喂养指数与婴幼儿Z评分之间的相关性。结果喂养指数由持续母乳喂养、奶瓶使用、过去24小时膳食摄入种类和膳食摄入频率、过去一周辅食添加天数、配方奶首添时间、除配方奶外其他辅食首添时间7部分组成;城市婴幼儿喂养指数评分显著高于农村(P<0.05);城市6～8月龄组婴幼儿喂养指数得分低于9～24月龄组婴幼儿(P<0.05);城市婴幼儿喂养指数与WAZ、WHZ显著负相关(P<0.05),农村喂养指数与HAZ显著正相关(P<0.05),与WHZ显著负相关(P<0.05)。结论本研究建立的喂养指数可有效评价我国6～24月龄婴幼儿的喂养情况。

Methodology of infant and young child feeding index for children aged 6-24 months in China

Objective To establish a infant and young child feeding index(ICFI) in China to comprehensive evaluate the feeding of children aged 6-24 months.Methods Based on the feed index concept defined by Ruel and Menon in 2002,and according to the feeding principle by WHO and Chinese dietary guidelines for children aged 0-6 years,the feed index for infants and young children was built and the variables were scored.Then using WAZ,HAZ and WHZ,the correlation between ICFI and Z score for children in urban and rural of three provinces(Sichuan,Hebei and Heilongjiang) was evaluated.Results The ICFI was constituted by 7 parts: continued breast-eeding,bottle-feeding,dietary diversity for the past 24h,frequency of feeding solids/semisolids for the past 24h,food frequency for the past 7d,the supplementary time of the formula milk and other foods.The difference of ICFI score between urban and rural group was significant(P < 0.05).In urban,the ICFI score of children aged 6~8months was lower than that of children aged 9-24 months.In urban,the negatively correlation between ICFI and WAZ WHZ was significant(P <0.05).In rural,the negatively correlation between ICFI and WHZ was significant(P <0.05),while the positively correlation between ICFI and HAZ was significant(P <0.05).Conclusion ICFI is effective to evaluate the infant feeding in China.
