目的评价中国农村婴幼儿喂养指数与儿童营养状况的关系。方法利用2005年中国农村儿童营养监测调查数据,根据6～23月龄婴幼儿的母乳喂养和辅食添加情况,建立年龄别婴幼儿喂养指数,并分析婴幼儿喂养指数与年龄别身长Z评分(LAZ)和年龄别体重Z评分(WAZ)的关系。结果中国农村婴幼儿喂养指数为(8.61±2.56),6～、9～和12～23月龄儿童喂养指数均与LAZ显著相关(P<0.01),9～和12～23月龄儿童喂养指数与WAZ显著相关(P<0.05)。调整了相关影响因素后,婴幼儿喂养指数与儿童LAZ、WAZ依然显著相关(P<0.01),其中24小时辅食添加种类和辅食添加次数、1周内辅食添加与LAZ相关(P<0.01),母乳喂养、24小时辅食添加次数和一周内辅食添加与WAZ相关(P<0.05)。结论婴幼儿喂养指数可以反映我国农村儿童的喂养状况,并评价婴幼儿喂养行为对其营养状况的影响。
Objective To evaluate the relationship between infant feeding index and nutritional status of children in rural China. Methods According to the survey data of 2005 China rural children nutrition monitoring, according to the breastfeeding and complementary food supplement of infants aged 6 ~ 23 months, the index of feeding age of infants and young children was established, and the relationship between infant feeding index and age Z score (LAZ ) And age-specific weight Z score (WAZ). Results The feeding index of infants and young children in rural China was (8.61 ± 2.56), and the feeding index of children aged 6 ~ 9 and 12 ~ 23 months were significantly correlated with LAZ (P <0.01). The feeding index of children aged 9 ~ and 12 ~ 23 months Significantly correlated with WAZ (P <0.05). After adjusting for the influencing factors, infant feeding index was significantly correlated with LAZ and WAZ in children (P <0.01), including the types of supplementary food supplemented with food supplement and the number of complementary food supplementation in 24 hours, and LAZ (P <0.01) Breastfeeding, supplementation with 24-hour food supplement, and complementary food supplement within one week were associated with WAZ (P <0.05). Conclusion The infant and young child feeding index can reflect the feeding status of rural children in our country and evaluate the impact of infant feeding on their nutritional status.
