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10g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24h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。
Objective To evaluate the short-term effect of meat block model on the guidance of infant feeding and to explore a new method of feeding intervention in rural children during weaning period. Methods Using convenient sampling, parents of 263 children aged 6 ~ 11 months in two townships of Zhao County, Hebei Province were given 6-month feeding intervention guidance. 10g cooked pork lean model was used to assist in the assessment of meat consumption. Results Children’s meat consumption increased with age, and the trend of meat consumption increased with hemoglobin level in one week. Compared with the baseline survey, the pre-and post-increment value of carcass meat intake in the intervention group and the control group was 30.54 (23.09, 37.98) g and 6.24 (2.56, 9.93) g respectively in the interim survey (P = 0.000 1) The survey was 36.33 (23.77, 48.89) g and 19.74 (7.57, 31.91) g respectively (P = 0.073). Meat consumption of 4.7% of the children in the intervention group and 1.8% of the control group reached the recommended minimum amount of items for 24 hours (P = 0.190) and 4.7% and 1.8% for the final survey (P = 0.060). Conclusion The method of meat block model received the acceptance and cooperation of parents of infants and young children, initially realized the quantitative calculation of children’s meat consumption, and the improvement of diet appeared.
