摘要
目的掌握河南省水源性高碘地区分布和高碘甲状腺肿流行情况,更好地落实防治措施。方法以乡为单位进行全省外环境水碘基线调查;对全省原碘缺乏病非病区进行流行病学抽样调查。结果发现位于豫东黄河冲积平原的18个县(市、区)水碘较高,在测定的5 023份水样中,水碘值在150 μg/L以上的占47.6%;高碘水源呈片状分布,呈乡与乡、县与县连在一起;高碘地区和适碘地区并存。碘的摄入量与甲状腺肿的流行存在明显的剂量-效应关系,学龄儿童的甲状腺肿大率随水碘的升高而升高。结论河南省豫东黄河冲积平原18个县(市、区)所辖的164个乡为水源性高碘地区和高碘病区,存在高碘甲状腺肿的地方性流行。
Objective To know the distribution of water-source-originated high level iodine districts and the rate of high level iodine goiter. Methods Investigation on outer environment iodine baseline in whole province on township level; sampling investigation on formerly non-goiter regions in the whole province. Results The fact that higher iodine level in 18 counties was found, the proportion of more than 150 μg/L was 47.6% in 5 023 water samples; high level iodine regions were patched-shaped, linked by town to town or county to county; high iodine regions and advisable iodine regions were coexist. Iodine intake and epidemic of goiter showed definite dose-effect relationship. Conclusions The fact that goiter epidemics in 162 towns of 18 counties in the Yellow river delta of east-Henan province is confirmed.
