[Cost-benefit analysis on the intervention of application iron-fortified soy sauce for anemia in Deqing 15-54 years women, Zhejiang].

OBJECTIVE: To make a cost-benefit analysis on anemia intervention with iron-fortified soy sauce in 15-54 years old women. METHODS: The study was conducted in Deqing county, Zhejiang province in 2012-2013. A total 585 women as sampling size were estimated with statistical model and randomly selected by probability proportionate to size sampling.

The major cost of the project was 156 400 RMB, and total benefits result ing from projects were 1 448 485 RMB. The cost-benefit ratio of the project is 1∶9.49. If investing one yuan can produce economic benefits of nearly 9.49 yuan, therefore, the intervention projectis worth to be scaling up. Sensitivity analysis showed the result of this study was stable.
