河北省高碘地区8~10岁儿童碘营养状况调查
Chinese Journal of Endemiology(2007)
Abstract
目的 调查河北省高碘地区8~10岁儿童碘营养状况.方法 采用人口比例概率方法抽样,盐碘测定采用直接滴定法,水碘测定采用砷铈接触法,尿碘测定采用过硫酸铵消化-砷铈催化分光光度方法.结果 检测居民饮用水样85份,水碘中位数为166.0 μg/L;测定居民户盐样301份,盐碘中位数为28.8 mg/kg,碘盐覆盖率为70.43%;检测8~10岁儿童一次即时尿样363份,尿碘中位数为418.8 μg/L,尿碘>300 μg/L为248份,占总数的68.0%;水碘>150 μg/L调查点的儿童尿碘中位数与水碘中位数相关(r=0.539,P<0.05),而与盐碘中位数不相关.结论 河北省高碘地区8~10岁儿童碘营养过剩,碘盐加重了这种状况,应停止供应碘盐.
