摘要
目的了解唐山市居民生活饮用水水碘含量现状以及对8-10岁儿童尿碘水平的影响,为完善碘缺乏病防治策略提供科学依据。方法唐山市范围内以行政村为单位,采集每个村饮水水源水样,测定水碘含量;按要求在各县区各随机抽取的5所小学中各随机抽检20名8-10岁儿童（男、女各半）的尿样。比较县区之间水碘含量、尿碘水平;按是否为沿海地区将县区分城两组,比较两组之间水碘、尿碘是否存在差异;探讨水碘含量与儿童尿碘水平之间的相关性。结果共调查水源8 337个,覆盖全市14个县市区、5 351个行政村。各县区水碘含量在0-64.93 ug/L之间;其中水碘值〈10 ug/L的水源为7 764个,占总水源数的93.13%;沿海的4个县区水碘含量高于非沿海的地区,差异有统计学意义（Z=-2.26,P〈0.05）。共检测尿样1 501份,尿碘中位数为230.7 ug/L,尿碘含量低于50 ug/L的比例为5.2%;沿海的4个县市区尿碘水平与非沿海地区差异无统计学意义（Z=-0.42,P〉0.05）。水碘含量与尿碘之水平之间差异无统计学意义（r=0.468,P=0.09）。结论低剂量水碘对儿童尿碘水平影响不明显。该市为外环境碘缺乏地区,仍需实施食盐加碘防治碘缺乏病的政策;儿童尿碘水平达到了国家要求,但应加强居民碘营养监测。
Objective To understand the current situation of residents water iodine level and effects on the urinary iodine concentrations of children aged 8 - 10 years in Tangshan city, in order to provide a scientific basis for the relevant policy to iodine deficiency disorders. Methods Take village as unit within the limits of Tangsban city, collected water samples in each village, investigate the content of water iodine ; 20 Children aged 8 to 10 （half and half for female and male） were randomly sampled in 5 primary schools in each county. Then compared the values of water iodine and urinary iodine concentrations between each county; divided into 2 teams based on whether areas were coastal region or not, compared if there exist differences on water iodine and urinary iodine between 2 teams; discusse the correlations between water iodine and children urinary iodine concentrations. Results A total of 8337 water samples were investigated, covered 14 counties in the whole city, 5351 administrative villages. Content of water iodine in the range of 0 which water iodine level 〈 10 ug/L were 7764, took 93.13% of the village 64.93 ug/L of each county; water iodine value; The level of water iodine in 4 coastal regions was significantly higher than the non coastal regions, there was significant statistic differences （Z = - 0. 42, P 〉 0. 05 ） . Tested 1501 urine total samples, the median of urine iodine concentration is 230.7ug/L, and the proportion that the concentration less than 50 ug/L is 5.2%. There wasn t significant different between urine iodine concentration in coastal region and that of nom coastal region （ r = 0. 468, P = 0. 09） . Conclusions Content of water iodine not correlate significantly with urinary iodine concentrations of children. This city was the outer environment iodine deficiency areas, where salt iodization to prevent and control iodine deficiency disorders were still needed; Children＇s urine iodine level reaches the national request, but still need to strengthen the residents＇ iodine n
