目的:对部分居民尿碘水平和甲状腺B超进行检查,综合评价其碘营养状况,为科学补碘策略提供依据。方法:连续居住5年及以上居民为调查对象,共选取356户1 110人,调查水碘、尿碘、盐碘含量及甲状腺B超检查和100户居民户日人均盐摄入量水平调查。结果:水样15份,中位数2.94ug/L;盐样316份,中位数33 mg/kg,尿样1110份,中位数为165.0 ug/L,甲状腺B超检查1 110人,异常341人,异常率30.72%,100户居民户日人均盐摄入量6.16g。结论:该区已达到消除碘缺乏病目标,目前的食盐加碘量总体是适宜的,居民碘盐摄入量处在安全范围。甲状腺B超异常率不随尿碘水平增加而上升。
Objective: To examine the level of urinary iodine and thyroid B ultrasound in some residents, and evaluate their iodine nutrition status comprehensively to provide the basis for scientific iodine supplement strategy. Methods: A total of 356 households with 1110 residents were enrolled in this study. Residents who lived for 5 consecutive years or more were investigated. Water iodine, urinary iodine, salt iodide content, thyroid B ultrasound examination and per capita salt intake of 100 households were investigated. Results: There were 15 water samples with a median of 2.94ug / L, 316 salt samples with a median of 33 mg / kg and a urine sample of 1110 with a median of 165.0 μg / L, 1101 thyroid B- Abnormal 341 people, anomalous rate 30.72%, 100 households daily average salt intake 6.16g. Conclusion: The goal of eliminating iodine deficiency disorders has been reached in this area. The current iodization amount of salt is generally suitable, and the iodine salt intake of residents is in the safe range. Thyroid B-abnormal rate does not increase with increasing urinary iodine levels.
