Abstract: Objective To explore the quantitative evaluation method with meat model on infant weaning feeding,and the effects of feeding counselling inventions with the meat model in rural areas. Method The infants aged 6 to 11 months which were enrolled in study on intervention of infant weaning feeding in rural area were evaluated meat intake during previous 24 hours and the past week,comparing with standard 10 g meat module. Results Infants' meat intake amount in previous 24 hours and the past week increased during the follow-up,and the later one indicated the similar trend with hemoglobin level.The increasing of meat intake in past week was higher in the intervention group than the control group after 3 months significantly[30.54(23.09,37.98)g vs 6.24(2.56,9.93)g,P=0.000 1],but not significantly after 6 months[36.33(23.77,48.89)g vs 19.74(7.57,31.91)g,P=0.073].The proportion of infants met recommended meat intake in 24 hours was higher in intervention group than the control group after 3 months (4.7% vs 1.8%,P=0.190)and after 6 months (4.7% vs 1.8%,P=0.060). Conclusions The quantitative evaluation method with meat model on infant weaning feeding is accepted by the caregivers and work out on value of infant meat intake.The effect on feeding counselling with meat module is indicated.

摘要： 目的 评价肉块模型用于婴幼儿喂养指导的短期效果,探索农村离乳期儿童喂养干预的新方法。方法 采用方便抽样,对河北省赵县两个乡镇263名6~11月龄儿童的家长进行6个月喂养干预指导,使用10 g熟猪瘦肉模型辅助评估食肉量。结果 儿童食肉量随年龄推进而增加,1周食肉量与血红蛋白水平的上升趋势基本一致。相对于基础调查,干预组和对照组儿童1周食肉量的自身前后增加值在中期调查时分别为30.54(23.09,37.98)g和6.24(2.56,9.93)g(P=0.000 1);终末调查时分别为36.33(23.77,48.89)g和19.74(7.57,31.91)g(P=0.073)。4.7%的干预组儿童和1.8%的对照组儿童24 h食肉量达到项目推荐最小量(P=0.190),终末调查时为4.7%和1.8%(P=0.060)。结论 肉块模型方法得到婴幼儿家长的接受和配合,初步实现儿童食肉量的定量计算,膳食改善效果显现。
