衡水市水源性高碘地区儿童碘营养与甲状腺肿现状调查

目的了解高碘地区重点人群碘营养状况以及病情变化趋势。方法选取居民饮用水水碘中位数在150～300μg／L的3个高碘乡，监测8—10岁儿童尿碘含量、8～10岁儿童甲状腺肿大情况（B超法）、居民饮用水碘含量、居民户盐碘含量。结果本次共应用B超检8～10岁儿童643人，甲状腺肿大47人，平均肿大率为7．31％。检测8～10岁儿童尿碘323份，尿碘中位数456．7μg/L。水碘39份，水碘中位数为256．4μg／L。居民户盐样320份，无碘盐率为78．4％。结论衡水市水源性高碘地区8—10岁儿童碘营养过量，儿童甲肿率处于较高发病水平，重点人群受高碘危害较为严重，形势不容乐观。应进一步加强改水及无碘盐供应管理，确保高碘地区群众健康。

Survey of iodine nutrition and incidence of goitre in water-borne hyper iodine area in Hengshui City

Objective To understand iodine nutrition and incidence of goitre in target population of high iodine area in Herngshui city. Methods The urinary iodine content,incidence of goitre in children aged 8-10 years in three townships with median iodine of 150-300μg/L in drinking water and household salt iodine content were selected and detected （B-ultrasound）. The results were analyzed. Results Totally 643 children aged 8-10 years were surveyed and 47 of them were found to be with goitre with an average goitre rate of 7.31%. Three hundred and twenty-three urinary iodine samples were detected and the median urinary iodine was 456.7μ g/l. Thirty-nine drinking water iodine samples were detected and the median water iodine was 256.4μg/l. While 78.0% of the 320 iodinized salt samples detected were without iodine. Conclusions The iodine nutrition in 8-10 years old children in high iodine area in Hengshui city exceeds the standard, the goitre incidence is high and the health of target population is seriously affected. Thus effective measures including improvement of drinking water quality and maintaining the content of iodinized salt be t taken to protect the health of the local residents.
