农村6〜23月龄婴幼儿营养包干预的成本-效益分析

Cost-benefit analysis of Ying Yang Bao(YYB)intervention in 6 to 23 months rural infants

目的通过山西、湖北和云南6个县干预项目监测,观察营养包对6~23月龄婴幼儿贫血和生长迟缓的改善并进行成本-效益分析。方法贫困地区儿童改善项目为6~23月龄婴幼儿发放营养包,并监测婴幼儿生长迟缓及贫血状况,运用微观经济学PROFILING模型进行分析,评估儿童服用营养包的经济效益。结果监测干预对象6~23月龄婴幼儿10672名,项目监测成本总计257.09万元。2012-2020年营养包项目通过改善生长迟缓和贫血带来的经济效益总计为1492.13万元,平均成本效益比为1:5.8。敏感性分析表明,营养包改善婴幼儿营养状况的成本-效益比具有稳定性。结论山西、湖北和云南三省六县6~23月龄婴幼儿营养包干预项目具有良好的成本-效益比。

OBJECTIVE To study on the cost-benefit from anemia and stunting reduction of Ying Yang Bao(YYB)intervention in 6 to 23 months rural infants in the six counties of Shanxi,Hubei and Yunnan provinces.METHODS YYB was distributed to 6-23 months infants in 6 counties by YYB nutrition intervention project.The numbers of childhood recovered from stunting and anemia was collected by a designed project monitoring plan.The cost-benefit was analyzed with PROFILING model as a nutritional microeconomic tool.RESULTS Total numbers of monitored infants was 10672 while the total cost of YYB intervention was estimated 2.57 million RMB.From 2012 to 2020,the total benefit was 14.92 million RMB from recover of stunting and anemia by YYB project and the average cost-benefit ratio of 6 counties was 1:5.8.Sensitivity analysis showed the result of this study was stable.CONCLUSION The YYB nutrition intervention for infants aged 6-23 months in the six counties of Shanxi,Hubei and Yunnan provinces showed a high cost-benefit ratio.
