【摘要】 目的 了解病区人群普供硒碘盐预防和控制克山病的效果。方法 2000年进行克山病病情及硒水平本底调查后，从2001年1月起全面供应含硒7～14mg/kg的硒碘盐，同时进行克山病病情及硒水平监测。结果 硒碘盐生产的合格率为100%，覆盖率为100%；病区使用盐硒水平由0.0025μg/g提高到6.475μg/g，儿童发硒水平由0.2633μg/g提高到0.5278μg/g；潜在型克山病检出率为0.2%；亚急型克山病发病率下降为0。结论 食盐中强化硒可以纠正病区人群硒营养缺乏状态，达到预防控制克山病的目的。

    【Abstract】Objective To understand the effect selenium iodized salt supplied for the prevention and control of Keshan disease.Methods At the end of the Keshan disease and selenium levels investigation in 2000, starded to full supply Se 7 ~ 14mg/kg of selenium salt, at the same time done the Keshan disease and selenium level monitoring from January 2001 to 2004.Results Selenium salt production in the passing rate was 100%, 100% coveraged; the selenium level of salt was increased from 0.0025μg / g to 6.475μg/g, the hair selenium levels of children was increased from 0.2633μg / g to 0.5278μg / g ; the potential Keshan disease detection rate was 0.2 percent; subacute Keshan disease incidence dropped to 0.Conclusion selenium salt can correct nutritional deficiencies of selenium status of populations, prevent and control the Keshan disease. ......
