摘　　要：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 understand the present condition of iodine excess areas and edible salt at household levels in Dezhou city, so as to provide the preventive intervention to control it.Methods A cross section was adopted for the epidemiological survey based on the east, west, south, north and central in all of townships each county. 2 samples of drinking water from each village were tested their water iodine content as well as the data regarding their recourses and the depth of wells. 5 samples of edible salt were collected in each village for quantitative analysis.Results We investigated 625 villages in 125 townships of 11 counties. 1 228 water samples were collected and tested. The recourses of drinking water are mainly from shallow wells with 174. 47±170.54 μg iodine/L in mean value or 121.61 μg iodine/L(0.65～917.49 μg/L) in medium. The ratio of iodized salt from 1 228 households was 94.9%. 250 thousand population are at risk for iodine excess and living in 58 townships of 10 counties where iodine concentration is over 150 μg/L in drinking water. All the iodine excess areas are located in alluvial plain.Conclusions This study suggested that iodized salt intervention should be stopped in all townships with the problems of iodine excess according to the Regulation and starting the health education project.Monitoring programme is also important in these areas after stopping iodized salt.
