摘要
目的 了解陕西省新确认水源性高碘地区改水降碘落实情况,掌握重点人群碘营养水平,科学评价新确认水源性高碘地区高碘防治效果,为采取针对性防治措施和干预策略提供参考依据。方法 根据《水源性高碘地区监测方案》(2018版),在陕西省新划定的水源性高碘地区选取63个行政村为监测点,进行居民饮用水水碘含量检测;在每个监测点抽取8~10岁非寄宿儿童40名(男女各半)和孕妇20名,进行儿童及孕妇甲状腺B超检查、家中食用盐盐碘、尿碘检测。结果 共采集水样190份,水碘中位数121.75μg/L。检测盐样2 159份,未加碘盐食用率17.79%,不同县区居民未加碘盐食用率差异有统计学意义(χ^(2)=722.85,P<0.001)。检测儿童尿碘1 924份,尿碘中位数为314.06μg/L;甲状腺B超检查1 879人,甲状腺肿大率和结节率分别为3.57%、20.33%。检测孕妇尿样229份,孕妇尿碘中位数为240.08μg/L;孕妇甲状腺B超检查143人,未发现甲状腺肿大者,甲状腺结节检出23人,甲状腺结节率为16.08%。不同高碘县区儿童尿碘中位数、甲状腺肿大率、甲状腺结节率差异均有统计学意义(H=371.65,χ^(2)=48.18、389.63,P均<0.05),不同高碘县区孕妇尿碘中位数、甲状腺结节率差异均有统计学意义(H=22.65,χ^(2)=12.35,P均<0.05)。结论 陕西省新确认水源性高碘地区改水降碘防治措施落实不到位,高碘防治效果欠佳,应进一步加强新确认水源性高碘地区高碘危害综合防治措施落实,有效防控水源性高碘危害。
Objective To understand the implementation of water improvement and iodine reduction in newly identified high-iodine water source areas in Shaanxi Province,grasp the iodine nutrition level of key populations,and scientifically evaluate the effect of high-iodine prevention and control in newly identified high-iodine water source areas,so as to provide reference for the implementation of targeted prevention and control measures and intervention strategies.Methods According to the"Monitoring Plan for Areas with High Iodine Content in Water Sources"(2018 edition),63 administrative villages were selected as monitoring sites in areas with high iodine content in water sources in Shaanxi Province to detect the iodine content in drinking water.4O non-boarding children(half male and half female)and 20 pregnant women aged 8-10 years were selected from each monitoring site.B-ultrasound examination of thyroid,iodine of edible salt at home and urine iodine of children and pregnant women were conducted.Results A total of 190 water samples were collected,with a median iodine of 121.75μg/L.Among 2159 salt samples,the consumption rate of uniodized salt was 17.79%,and there was significant difference among residents in different counties(X^(2)=722.85,P<0.001).The median urine iodine of 1924 children was 314.06μg/L.In 1879 patients,the rate of goiter and nodule was 3.57%and 20.33%,respectively.The median urine iodine of 229 pregnant women was 240.08μg/L.In 143 pregnant women,thyroid nodule was detected in 23 pregnant women,whose thyroid nodule rate was 16.08%.There were significant differences in urinary iodine median,goiter rate and thyroid nodule rate among children in different high iodine counties(H=371.65;X^(2)=48.18,389.63,P<0.05),there were significant differences in median urinary iodine and thyroid nodule rate among pregnant women in dfferent high-iodine counties(H=22.65,X^(2)=12.35,P<0.05).Conclusion The implementation of water improvement and iodine reduction prevention and control measures in newly confirmed water sou
