摘　　要：目的评价营养包对四川理县6～23月龄婴幼儿的营养改善效果。方法在理县为全县所有6～23月龄婴幼儿,每天补充一包富含蛋白质、维生素、微量元素的营养包,干预15个月,在项目开始前和结束后共抽取有代表性的510名6～29月龄婴幼儿测定身长、体重和血红蛋白水平,分析干预前后不同月龄(分为6～11、12～17、18～23、24～29月龄)的年龄别体重(WAZ)、年龄别身长(HAZ)、低体重率、生长迟缓率、血红蛋白值及贫血患病率的差异。结果营养包干预15个月后,理县6～11、18～23月龄HAZ分别较基线增加0.51和0.44,差异有显著性(P<0.05)。18～23月龄婴幼儿的生长迟缓率与基线差异有显著性(χ2=6.897,P<0.05)。4个年龄段的婴幼儿平均血红蛋白浓度分别增加12.7、11.4、16.7和15.7g/L,每个年龄段的贫血率与基线差异均有统计学意义(χ2分别为15.863、24.302、37.365、25.990,P<0.001)。结论通过给6～23月龄婴幼儿补充优质蛋白、维生素和微量元素的豆粉包15个月后,可以显著降低婴幼儿的生长迟缓率和贫血患病率。Objective This project aimed to investigate the nutrition status of infants and young children aged 6-23 months before and after the Yingyangbao intervention in Lixian county in Sichuan province.Methods The infants and young children aged 6-23 months in Lixian county were fed one sachet Yingyangbao which contains protein,vitamins and micronutrients per day for 15 months.The length,body weight and hemoglobin were measured for 510 infants and young children featured representative characteristics in Lixian County before and after Yingyangbao intervention.The statistical analysis was conducted to analyze the WAZ,HAZ,the low weight rate,the stunting rate,the anemia rate and the hemoglobin concentration of the infants and young children aged 6-11 months,12-17 months,18-23 months and 24-29 months,respectively.Results The results of the statistical analysis showed that the HAZ scores of the infants and young children aged 6-11 and 18-23 months increased 0.51 and 0.44 compared to the baseline,respectively.They were significantly higher than those of the baseline（P〈0.05）.The stunting rate of young children aged 18-23 months was significantly lower than the baseline（P〈0.05）.The concentration of the hemoglobin in each group among the 4 groups increased 12.7,11.4,16.7 and 15.7 g /L compared to the baseline,respectively.The total anemia prevalence among infants and young childre in each age group was significantly lower than the baseline（χ^2 = 15.863,24.302,37.365,25.990,respectively,P〈0.001）.Conclusion It was concluded that Yingyangbao which contains quality protein,vitamins andmicronutrients intervened 15 months could be effective for the growth and improvement of anemia of infants and young children aged 6-23 months.
