摘要
目的掌握新乡市水源性高碘地区分布规律及其流行病学状况,为采取科学防治对策提供依据。方法采取横断面调查。以乡(镇)为单位对居民饮用水水碘含量调查,并对发现的水源性高碘乡(镇)8~10岁儿童甲状腺肿大率、尿碘进行调查分析。结果检测水样2 625份,范围在2.0~963.8μg/L,水碘值在150μg/L以上的占45%;高碘水源呈片状分布,乡与乡、县与县连在一起,高碘地区与非高碘地区并存。8~12岁儿童尿碘中位数为536.8μg/L,甲状腺肿大率为4.2%。结论新乡市黄河冲积平原3个县所辖的23个乡(镇)为水源性高碘地区。
Objective To master the present conditions of excess iodine and its epidemiology in Xinxiang city for providing the evidence for control.Methods Across section was adapted for the epidemiological survery in all of townships from 3 counties.Two to five samples of dringking water from village were tested for water iodine content,urine iodine level and thyroid condition of elementary students were tested in the area with high water iodine.Results The proportion of more than 150 μg/L was 45% in 2 625 water samples;high level iodine regions were patched-shaped,linked by town to town or county to county;high level iodine regions and advisable iodine regions were coexisted.The urinary median iodine in 1 010 children were 536.8 μg/L.Thyroid goiter rate(TGR) of 1 027 subjects was 4.2%.Conclusion The fact that high water iodine region in 23 towns of 3 counties in the yellow river of east-Xinxiang city was confirmed.
