新疆2127名育龄期妇女的碘营养状况

Iodine nutrition in 2127 childbearing age women in Xinjiang

【目的】调查并分析新疆育龄期妇女的碘营养状况,为科学补碘提供依据。【方法】采用分层整群随机抽样方法,以新疆12个县18~52岁育龄期妇女2 127名为调查对象,采用砷铈催化分光光度测定法测定其尿碘。【结果】2 127名育龄妇女的尿碘中位数为195.0μg/L,尿碘的四分位间距为120.5~282.5μg/L。其中,尿碘值<100μg/L占17.9%;尿碘值介于100~300μg/L占62.2%;尿碘值≥300μg/L占19.8%。不同年龄段育龄妇女尿碘值比较,差别无统计学意义(χ2=0.682,P>0.05)。服用碘油丸和未服用碘油丸地区的育龄妇女尿碘值比较,差别有统计学意义(χ2=0.003,P<0.01)。【结论】新疆育龄期妇女碘营养状况处于适宜水平。口服碘油丸可能存在碘过量的风险,建议继续加强育龄期妇女碘营养状况监测,指导育龄期妇女科学补碘。

[Objective] To investigate and analyze the iodine nutrition status of Xinjiang childbearing age women,providing the basis for scientific iodine supplement. [Methods] Using stratified cluster random sampling method,2 127 respondents were sampled from childbearing women aged 18 - 52 from 12 counties.The arsenic cerium catalytic spectrophotometry was used to determine urine iodine. [Results] The median urinary iodine of 2 127 childbearing age women was 195. 0 μ g/L,urine iodine distribution ranged between120. 5 and 282. 5 μg/L. The proportion of urine iodine value 〈 100 μg/L was 17. 9%; Urinary iodine between 100 ~ 300 μg/L accounted for 62. 2%; Urine iodine value above 300 μg/L accounted for 19. 8%or more. Comparing urinary iodine value of different age groups of childbearing age women,no statistically significant difference was found（ chi-square = 0. 682,P〉0. 05）. Comparing urinary iodine value of childbearing age women between those regions taking iodine oil pills and not taking iodine oil,the difference was statistically significant（ chi-square = 0. 003,P 〈 0. 01）. [Conclusion] The iodine nutritional status of childbearing age women in Xinjiang was at adequate level. Iodine excess risk may exist in taking oral iodine oil pill. It is suggested that we should continue to strengthen the monitoring of the iodine nutritional status in childbearing age women,guide the childbearing age women to scientifically intake the iodine.
