目的了解大连地区2015年孕妇的尿碘水平,为该地区防止孕妇碘缺乏病工作提供科学的理论依据。方法采集大连地区1 000例健康孕妇尿液,采用砷铈催化分光光度法(WS/T107-2006)检测尿碘含量。结果大连地区孕妇总缺碘率达51.4%,其中城区缺碘率为57.0%,郊区农村缺碘率为47.7%,城区孕妇缺碘率明显高于郊区农村孕妇。大连地区孕妇尿碘中位数为145.33μg/L,低于国家标准适宜水平下限(150μg/L),其中城区孕妇尿碘中位数为140.0μg/L,郊区农村孕妇尿碘中位数为153.7μg/L。结论大连地区应继续采取食盐加碘的防治措施,并实时开展尿碘监测,积极宣传,提高孕妇人群碘营养水平。
Objective To understand the level of urinary iodine in pregnant women in Dalian in 2015 and provide a scientific basis for preventing iodine deficiency in pregnant women in the area. Methods Urine was collected from 1 000 healthy pregnant women in Dalian. Urinary iodine content was determined by arsenic cerium catalytic spectrophotometry (WS / T107-2006). Results The total iodine deficiency rate of pregnant women in Dalian reached 51.4%, among which the iodine deficiency rate in urban areas was 57.0% and the iodine deficiency rate in rural areas was 47.7%. The iodine deficiency rate in pregnant women in urban areas was significantly higher than that in rural areas in rural areas. The median urinary iodine of pregnant women in Dalian was 145.33μg / L, lower than the lower limit of national standard (150μg / L). The median urinary iodine of pregnant women in urban areas was 140.0μg / L, and the median urinary iodine of rural pregnant women in rural areas was 153.7 μg / L. Conclusion Dalian should continue to take salt iodization prevention and control measures, and urine iodine monitoring in real time, and actively publicize and improve the iodine nutrition of pregnant women population.
