Objectives： To assess the cost-effectiveness of periconceptional folio acid supplementation for reducing neural tube defects （NTDs） in China. Methods： From the social perspectives, cost effectiveness analysis of supplementation of folio acid is conducted by the decision tree model. Sensitiveness analysis is done to test the robustness of the model. Results： In a cohort of 10 000 periconceptional wowen,the strategy covering all nation （FA2） and the strategy covering both urban and rural in the north and rural in the south （FA4） can avert more NTDs than the strategy covering north only （FA3）. Sensitiveness analysis reveals that NTD＇ s incidence, intervention cost and other factors influence strategies＇ cost effective. Conclusions： Periconceptional folio acid supplementation is a cost-effective intervention for preventing neural tube defects, and the strategy covering both north areas and rural areas in the south would better than other strategies in terms of effectiveness and cost-effectiveness.
