目的摸清德州市的水源性高碘地区分布和居民食用盐现况以制定预防干预策略。方法采用横断面调查方法,在每个被调查县(市、区)的所有乡(镇)均按照东、西、南、北、中五个不同方位各抽取5个村庄,每个村庄采集饮用水样2份进行水碘检测,并了解饮水类型及水井深度。每个村庄采集5户居民食用盐样各1份进行检测。结果调查了11个县(市、区)的125个乡(镇、街办)的625个村庄,检测饮用水样本1228份。水碘含量为(174.47±170.54)μg/L,中位数121.61μg/L(0.65～917.49μg/L);水井深度为(85.83±144.54)m,中位数28.0m(3.0～700m);居民户碘盐覆盖率94.9%。高碘地区(病区)分布在10个县(市、区)的58个乡(镇、街办),受累人口250.66万;高碘地区居民户碘盐覆盖率高达95,5%。结论建议按照《条例》规定在高碘地区停供碘盐,并实施改水降碘、健康教育和碘盐监测。 Objective To find out the distribution of water-based high-iodine in Dezhou and the current status of household salt to formulate preventive intervention strategies. Methods By cross-sectional survey, all villages (towns) in each of the investigated counties (cities, districts) took five villages in five orientations of East, West, South, North and Central. Each village collected drinking water 2 samples of water Iodine test, and understand the type of drinking water and depth of wells. Each village to collect 5 households residents of salt samples for testing. Results 625 villages in 125 townships (towns and streets) in 11 counties (cities and districts) were surveyed, and 1,228 samples of drinking water were tested. The water iodine content was (174.47 ± 170.54) μg / L and the median was 121.61 μg / L (0.65-917.49 μg / L). The water depth was (85.83 ± 144.54) m and the median was 28.0 m (3.0-700 m) Residential households iodized salt coverage 94.9%. High-iodine areas (wards) are distributed in 58 townships (towns and districts) in 10 counties (cities and districts) with a population of 2.5 million. The coverage of iodized salt in high-iodine areas is as high as 95.5%. Conclusions It is suggested to stop supplying iodized salt in areas with high iodine according to the provisions of the “Regulations” and implement water and iodine reduction, health education and iodized salt monitoring.
