目的了解舟山海岛孕妇碘营养状况,为制定和完善科学补碘提供依据。方法抽取舟山市2个县、区中2个居委会(村)的105名当地不同孕期的常住居民,共采集碘盐、水样、尿样分别进行盐碘、水碘、尿碘浓度检测,并对调查对象开展甲状腺超声检查,采集血样进行甲状腺功能检测。结果盐碘浓度的中位数为0 mg/kg、均数10.21 mg/kg,合格碘盐食用率为17.47%;水碘浓度均数为11.55μg/L;尿碘中位数为98.72μg/L;甲状腺超声检查总异常率35.53%;甲状腺功能总异常率为58.10%。结论舟山海岛孕妇的尿碘水平明显低于WHO/UNICEF/ICCIDD推荐的标准,甲状腺超声检查异常率、甲状腺功能异常率明显高于全省水平。
Objective To understand the nutritional status of iodine in pregnant women in Zhoushan Island and provide the basis for formulating and improving scientific iodine supplementation. Methods A total of 105 residents from two prefectures (districts) in 2 counties of Zhoushan City were enrolled in this study. Salt iodine, water samples and urine samples were collected for salt iodine, water iodine and urine iodine Conduct thyroid ultrasound examination of the respondents, blood samples collected for thyroid function testing. Results The median of salt iodine concentration was 0 mg / kg, the average was 10.21 mg / kg, the qualified iodized salt consumption rate was 17.47%, the average iodine concentration was 11.55 μg / L, and the median urinary iodine was 98.72 μg / L; the total abnormal rate of thyroid ultrasound examination was 35.53%; The total abnormal rate of thyroid function was 58.10%. Conclusion The urinary iodine level of pregnant women in Zhoushan Island was significantly lower than the standard recommended by WHO / UNICEF / ICCIDD. The abnormal rate of thyroid ultrasound examination and the abnormal thyroid function rate were significantly higher than those of the whole province.
