摘要: 【目的】 评价发放辅食营养包和开展健康教育对地震灾区宁强县婴幼儿营养状况的改善效果。 【方法】 对宁强县所有6~24月龄婴幼儿添加辅食营养包、对婴幼儿看护人开展婴幼儿喂养健康教育,在干预措施实施18个月前后,分别抽取327名和300名6~24月龄婴幼儿进行调查,对比干预前后婴幼儿的身高、体重、血红蛋白、WAZ(Weight-for-age Z-score)、HAZ (Height-for-age Z-score)、WHZ (Weight-for -Height Z-score)、低体重率、生长迟缓率、消瘦率以及贫血检出率的差异。 【结果】 6~24月龄婴幼儿干预后平均体重较干预前增加0.90 kg(t=-9.94,P<0.01),平均身长增加3.40 cm(t=-7.74,P<0.01),差异有统计学意义;干预后的WAZ(-0.48 vs 0.09,t=-6.95,P<0.01)、HAZ (-0.73 vs -0.25,t=-4.63,P<0.01))、WHZ(-0.15 vs 0.30,t=-4.90,P<0.01)均有显著提高;干预后婴幼儿血红蛋白平均浓度由10.94 g/dL提高到11.70 g/dL(t=-7.97,P<0.01),贫血检出率由49.5%降至23.9%( χ2=43.72,P<0.01)。 【结论】 通过18个月的营养干预可以显著改善宁强县6~24月龄婴幼儿营养状况。

Abstract: 【Objective】 To compare the nutrition status of infants before and after nutrition interventions in Ningqiang county. 【Methods】 The project provided nutrition interventions which feed infants aged 6~24 months one packet Yingyangbao per day and educated babysitter how to feed infants properly in Ningqiang county.Before and after the 18 months nutrition interventions,327 and 300 infants aged 6~24 months were sampled respectively to complete the investigation.Effectiveness of nutrition interventions was evaluated by analyzing the differences of infants' length,body weitht,hemoglobin concentration,WAZ,HAZ,WHZ,underweight rate,stunting rate,wasting rate and anemia rate between two samples. 【Results】 After the interventions,average weight and length of infants aged 6~24 months increased 0.90 kg(t=-9.94,P<0.01)and 3.40 cm(t=-7.74,P<0.01)respectively,and there were significant differences between before and after interventions.WAZ(-0.48 vs 0.09,t=-6.95,P<0.01),HAZ (-0.73 vs -0.25,t=-4.63,P<0.01) and WHZ(-0.15 vs 0.30,t=-4.90,P<0.01) also increased significantly.Through the nutrition interventions infants' hemoglobin concentration increased from 10.94 g/dL to 11.70 g/dL(t=-7.97,P<0.01),anemia rate decreased from 49.5% to 23.9%(χ2=43.72,P<0.01),and the results of statistical analysis showed that significant differences exist. 【Conclusion】 Through 18 months nutrition interventions the nutrition status of infants aged 6~24 months could be improved significantly.
