摘要
目的综合分析营养包对婴幼儿营养作用的研究观察结果,系统评价营养包营养干预效果。方法通过检索专业数据库及其他资源的文献,汇总营养包营养干预效果的研究数据。经文献质量评价后,纳入符合标准研究进行分析。使用的分析工具为Rev Man 5.3。结果本研究纳入9项研究报告,其中随机对照1项,随机前后对照8项,采纳报告中的13组干预前后比较试验数据。分析结果显示,营养干预可显著增加血红蛋白（MD=0.94,95%CI 0.72~1.15,P〈0.01）,降低人群贫血发生率（RR=0.34,95%CI 0.25~0.46,P〈0.01）。营养干预对年龄别体重和年龄别身长未见作用,但对身高别体重具有显著营养效果（MD=0.42,95%CI 0.19~0.65,P〈0.01）,减少婴幼儿低体重率发生（RR=0.53,95%CI 0.32~0.88,P〈0.05）。结论营养包对婴幼儿营养状况具有改善效果。
Objective To systematically review the nutritional effect of YYB on infants and young children in poor rural regions. Methods Medline,Pub Med,Cochrane Library,CNKI and other sources of nutrition and health information were retrieved with the predetermined key words. The quality of the obtained literatures was evaluated with the criteria established in this study. Rve Man 5. 3 was used in the meta analysis. Results Thirteen groups of qualified data from nine YYB intervention studies were used. The results showed that YYB significantly increased the level of Hb（ MD = 0. 94,95% CI 0. 94- 1. 15,P〈0. 01）,reduced the prevalence of anemia（ RR = 0. 34,95% CI 0. 25- 0. 46,P〈0. 01）. YYB showed no significant effect on WAZ and HAZ,but significant increase of WHZ was demonstrated by the analytical data（ MD = 0. 42,95% CI 0. 19- 0. 65,P〈0. 01）. Additionally YYB intervention groups also showed the prevalence of underweight（ RR =0. 53,95% CI 0. 32- 0. 88,P〈0. 05）. Conclusion As an infant complementary food supplement,YYB improved the nutrition status of infants and young children includingincreased Hb level,declined anemia prevalence and wasting rate.
