贵州省育龄妇女碘营养状况及血清促甲状腺激素水平调查

目的 了解贵州省育龄妇女碘营养状况及其促甲状腺激素（TSH）水平,为碘缺乏病防治工作提供依据。方法 在全省范围内,每市（州）选择政府所在地市（区）为城市调查点、抽取1个经济相对落后且距市（州）政府所在地较远的县（市、区）为农村调查点,每个调查点分别采集300份居民户食用盐测定盐碘、150名当地户籍孕前育龄妇女1次即时尿样,测定碘含量;在抽取调查点妇幼保健机构采集300人份无甲状腺疾病病史、甲状腺检查正常的孕前优生健康检查妇女静脉血,测定TSH。结果 全省调查居民户食用盐5 400份,盐碘中位数为27.9 mg/kg,合格碘盐食用率为94.8%;调查孕前育龄妇女尿碘2 693份,中位数为199.3 μg /L,各调查点尿碘中位数位于143.8～323.7 μg/L之间;采集育龄妇女静脉血5 400份,TSH中位数为1.75 mIU/L,各调查点TSH中位数位于0.86～2.33 mIU/L之间。结论 我省碘盐质量稳定,合格碘盐食用率符合要求,育龄妇女碘营养状况适宜,近年来防治效果良好。

Survey of iodine nutrition and serum TSH of childbearing age women in Guizhou Province

To survey the iodine nutritional status and serum TSH in childbearing age women in Guizhou Province,so as to provide evidence for the control of iodine deficiency disorders. Methods Each state chooses the city(district) where the government was located as the urban survey point, and one county(city, district) with relatively backward economy and far away from the city(district) site where the government located as the rural survey point. In each survey site, 300 samples were collected for salt determination of salt iodine, urine iodine of 150 childbearing age women were determined, 300 venous blood samples of childbearing age women without thyroid disease history and with normal thyroid examination were collected to determine TSH in the maternal and child health care institutions. Results 5400 household salts were tested, the median of salt iodine was 27.9 mg/kg, and the consumption rate of qualified iodized salt was 94.8%. Among the 2693 childbearing age women, the median of urinary iodine was 199.3 μg/L, and the median of urinary iodine at each survey point was between143.8-323.7 g/L. 5400 TSH were tested, and the median of TSH was 1.75 m IU/L, and the median TSH at each survey point was between 0.86-2.33 mIU/L. Conclusion The quality of iodized salt was stable, and the consumption rate of qualified iodized salt reached standard(>90%), and the iodine nutrition status of childbearing age women was suitable. The control of iodine deficiency disorders in Guizhou is effective.
