目的了解我市水源性高碘的分布及危害情况,为今后我市高碘地甲病防治工作提供基础资料。方法依照《河北省水碘分布调查实施方案》要求,按整群随机抽样的方法开展调查。结果全市18个县共采水样919份,碘含量在0.15～2840.4μg/L之间,有21个乡(镇)水碘中位数在150～300μg/L之间,属于高碘地区;40个乡(镇)水碘中位数>300μg/L,属于高碘病区。水碘含量与尿碘中位数之间有正相关关系,水碘含量越高,尿碘值亦越高。调查10个县20个乡(镇)8～10岁儿童4142名,发现甲状腺肿大273人,平均甲肿率6.59%。水碘含量与甲肿率之间有正相关关系,水碘含量越高,甲肿率亦越高。结论我市是高水碘危害比较严重的地区,做好水源性高碘的危害及防治对策研究是非常重要的。
Objective To understand the distribution and hazards of water-borne high iodine in our city and to provide the basic information for the prevention and treatment of high iodine A disease in our city in the future. Methods According to the requirements of “Implementation Plan of Water Iodine Distribution Survey in Hebei Province”, a random cluster sampling method was used to carry out the investigation. Results There were 919 water samples collected from 18 counties in the city with the iodine content ranging from 0.15 to 2840.4 μg / L, and the median iodine concentration in 21 townships was between 150 and 300 μg / L, which belonged to high iodine area. 40 townships (towns) water iodine median> 300μg / L, belonging to iodine deficiency zone. There is a positive correlation between the water iodine content and the median of urinary iodine, the higher the water iodine content, the higher the urinary iodine value. A total of 4142 children aged 8-10 years from 20 townships (towns) in 10 counties were investigated. 273 goiter patients were found, with an average rate of 6.59%. There is a positive correlation between water iodine content and the rate of goiter, the higher the water iodine content, the higher the rate of goiter. Conclusions Our city is a region where the hazard of high water iodine is more serious. It is very important to study the harm of water-borne high iodine and prevention and control measures.
