[Cost-Benefit Analysis of Ying Yang Bao (YYB) Intervention in 6 to 23 Months Rural Infants].

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 10 672 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.
