摘  要:目的 分析北京市大兴区榆垡镇改水降碘对历史水源性高碘地区人群碘营养和甲状腺肿大状况的影响,评价其防治效果。 方法 采用回顾性分析方法,收集2005 - 2016年北京市大兴区榆垡镇历次改水降碘前后饮用水碘含量、尿碘含量、甲状腺肿大率等流行病学调查资料,并进行比较分析。 结果 榆垡镇自2005年开始实施改水,截至2015年,建造改水降碘工程8个,全部历史高水碘村均完成了饮用水改造。2005、2009、2010、2011、2014年各采集水样64、12、26、26、37份,水碘中位数分别为185.2、20.9、14.1、16.8、21.6 μg/L,通过改水水碘中位数明显下降。2005、2009、2011、2016年各采集8-10岁学龄儿童尿样148、153、150、40份,尿碘中位数分别为520.1、201.6、143.0、135.0 μg/L,通过改水尿碘中位数下降至适宜范围(100-199 μg/L)。2005、2009、2011、2016年各对154、292、40、40名学龄儿童进行了甲状腺容积检测,分别检出甲状腺肿大者10、6、0、1名,甲状腺肿大率分别为6.49%、2.05%、0、2.50%,通过改水甲状腺肿大率降至5%以下。 结论 北京市大兴区榆垡镇水源性高碘地区改水后高水碘危害基本消除,改水降碘是水源性高碘地区控制高碘危害的根本措施。Objective To analyze the effects of change water sources on population iodine nutrition and goiter status in historical high water-iodine area in Yufa Town of Daxing District, Beijing, and evaluate the control effects. Methods A retrospective analysis method was used to collect epidemiological survey data such as water iodine content, urinary iodine content and goiter rate before and after iodine reduction in Yufa Town of Daxing District, Beijing, 2005 - 2016, and the data were compared and analyzed. Results Yufa Town had implemented water reform since 2005. As of 2015, 8 change water source projects had been built, and all historical high-water iodine villages had completed drinking water transformation. Totally 64, 12, 26, 26, and 37 water samples were collected and tested in 2005, 2009, 2010, 2011, and 2014, the medians of water iodine were 185.2, 20.9, 14.1, 16.8, and 21.6 μg/L, respectively, and the medians of water iodine decreased significantly through changing water source. Totally 148, 153, 150, and 40 urine samples of children aged 8 to 10 years old were collected and tested in 2005, 2009, 2011, and 2016, the medians of urinary iodine were 520.1, 201.6, 143.0, and 135.0 μg/L, respectively, and the medians of urinary iodine decreased to a suitable range (100 - 199 μg/L) through changing water source. Totally 154, 292, 40, and 40 school-age children were tested for thyroid volume in 2005, 2009, 2011, and 2016, and 10, 6, 0, and 1 thyroid enlargements were detected, respectively. The thyroid enlargement rates were 6.49%. 2.05%, 0, and 2.50%, and the rates of goiter were reduced to less than 5% through changing water source. Conclusion The high water-iodine in water-borne high iodine area in Yufa Town, Daxing District, Beijing is basically eliminated after change water sources, water improvement to reduce iodine is a basic measure to control high iodine damage in high water-iodine areas.
