目的掌握日照市防治碘缺乏病(IDD)的防治效果及居民碘营养状况,及时发现工作中存在的问题,为因地制宜、科学补碘提供参考依据。方法 2010年对全市所有自然村及居民饮用水供水点进行水碘含量检测;每个县按东、西、南、北、中方位抽取5～9个乡,每个乡抽取4个行政村,每个村抽取8～15户居民食用盐,进行盐碘检测;每个乡抽取1所小学,每所小学抽取60名8～10岁儿童,进行甲状腺检查,其中收集20名(每年龄组各1/3,男女各半)即时尿样,进行尿碘测定。水碘测定采用硫酸铈催化分光光度法,盐碘测定采用直接滴定法,尿碘测定采用砷铈催化分光光度法,儿童甲状腺检查采用触诊法。结果共检测水样3 483份,水碘范围为0.1～89.90μg/L,<10μg/L的水样3 161份,占90.76%;检测盐样1 164份,盐碘中位数29.8 mg/kg,碘盐覆盖率为98.71%(1 149/1 164),碘盐合格率为98.17%(1 128/1 149),合格碘盐食用率为96.91%(1 128/1 164);检查8～10岁儿童1 200名人,甲状腺肿大率为1.25%(15/1 200);检测8～10岁儿童尿样476份,尿碘中位数为150.65μg/L,5年级学生IDD防治知识知晓率为80.47%,及格率为81.32%。结论日照市属于沿海缺碘地区,IDD防治工作取得了明显成效,居民碘营养水平适宜,符合国家消除IDD标准要求,不存在碘缺乏和碘过量的问题。但IDD健康教育工作需亟待加强。
Objective To master the prevention and cure of idiopathic iodine deficiency disorders (IDDs) and the iodine nutrition status of residents in Rizhao, discover the problems in their work in time, and provide reference for adjusting the local conditions and scientific supplementing iodine. Methods Water iodine content was measured in all natural villages and drinking water supply points in the city in 2010; 5 to 9 townships were sampled from each county in the east, west, south, north and middle, and 4 administrative villages in each township A village of 8 to 15 households to take salt intake of salt iodine detection; extraction of a primary school per township, each primary school 60 children aged 8 to 10 years for thyroid examination, which collected 20 (1 for each age group / 3, male and female halves) Immediate urine samples for urinary iodine determination. Water iodine determination by cerium sulfate catalytic spectrophotometry, salt iodine determination by direct titration, urinary iodine determination by arsenic cerium catalytic spectrophotometry, thyroid examination by palpation method. Results A total of 3 483 samples of water samples were collected, with 3 161 samples of water <10μg / L and 90.76% of water samples with water iodine ranging from 0.1 to 89.90μg / L. kg, iodized salt coverage was 98.71% (1 149/1 164), iodized salt pass rate was 98.17% (1 128/1 149), qualified iodized salt consumption rate was 96.91% (1 128/1 164), inspection 8 1 200 children aged ~ 10 years with a rate of goiter of 1.25% (15/1 200), 476 urine samples of children aged 8 ~ 10 years with a median urinary iodine of 150.65 μg / L, knowledge of prevention and treatment of IDD The rate of awareness is 80.47%, passing rate is 81.32%. Conclusion Rizhao City is a coastal area with iodine deficiency. The IDD prevention and treatment work has achieved remarkable results. The iodine nutrition level of the residents is suitable, which meets the requirements of the State to eliminate IDD standards without the problems of iodine deficiency and iodine excess. However, IDD health education needs to be strengthened urgently.
