[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.
