Objective To analyze the effect of eliminating the iodine deficiency disorders and the “four three” comprehensive prevention and treatment strategies in Huating County, Gansu Province, and provide scientific evidences for the continued elimination of iodine deficiency disorders in the future. Methods to analyze and analyze the data of prevention and treatment of iodine deficiency disorders in Huating County for 10 years. Results A total of 2 830 household salt and 99.61% iodized salt were detected in households from 2004 to 2013, with significant difference in all years (χ2 = 23.53, P <0.05). The qualified rate of iodized salt was 96.74% (Χ2 = 96.59, P <0.05). The acceptable iodine salt consumption rate was 96.36%, with significant difference in all years (χ2 = 104.79, P <0.05). The goiter rate dropped from 5.46% in 2004 to 2013 (2.62%, P <0.05); urinary iodine median of 247.65μg / L, <50μg / L accounted for 2.66% 0.92%; 10-year questionnaire survey of fifth graders 1 758 people, awareness rate 87.09%, the awareness rate showed a trend of increasing year by year, the difference was statistically significant (χ2 = 43.67, P <0.05); survey housewives 1 363 People, awareness rate of 81.14%, no significant difference between the years (χ2 = 3.93, P> 0.05). Conclusion The goal of continuing elimination of iodine deficiency disorders was achieved. The establishment of the “three major working mechanisms” and the implementation of “three services” carried out “two projects for one project” and implementation of “three in one” health education and promotion Mode, etc. “Four three ” comprehensive prevention and control strategy has achieved remarkable results.
