摘要
目的了解徐州市泉山区孕妇碘营养状况，为该地区孕妇制订科学的补碘措施提供依据。方法采用整群随机抽样的方法，于2015年4月和2016年4月分别抽取孕中期、孕晚期孕妇各50名，采集其尿样和家中食用盐样，进行尿碘和盐碘检测。结果100名孕中期和100名孕晚期孕妇的尿碘中位数分别为241．5μg/L、177μg/L，2015年和2016年监测的孕妇尿碘中位数分别为184．5μg/L、214．5μg/L，差异均无统计学意义（P〉0．05）。在尿碘频数分布中，孕中期和孕晚期的碘适宜率、碘过量率差异均有统计学意义（P〈0．05）。食用非碘盐、不合格碘盐的孕妇缺碘率比食用合格碘盐的孕妇缺碘率显著增高，差异均有统计学意义（P〈0．05）。结论徐州市泉山区孕妇群体碘营养水平充足，但仍有36．5％的个体存在碘不足，10．5％的个体存在碘过量现象，需要进一步做好碘缺乏病的宣传和饮食指导工作，加大孕妇碘营养的监测力度，提高孕妇的碘适宜量的比例，保障胎儿智力的正常发育。
Objective To investigate the iodine nutritional condition of pregnant women in Quanshan District, Xuzhou, so as to provide sound evidence for iodine supplementation in the area. Methods A total of 50 pregnant women at the second trimester and 50 pregnant women at the third trimester were selected in April, 2015 and 2016. Their urinal samples and edible salt samples were collected for the urinary iodine test and salt iodine test. Results The median urine iodine （MUI） was 241.5 μg/L for pregnant women at the second trimester and 177μg/L for those at the third trimester. The MUI was 184.5μg/L in 2015 and 214.5 μg/L in 2016, without statistical difference （P 〉 0.05 ）. The urinary io- dine results revealed statistic differences in both optimal and excessive iodine intake levels among the second and trimester pregnant women （ P 〈 0.05 ）. The iodine deficiency rate among pregnant women taking non - iodized or substandard io- dine salt was remarkably higher than that among those taking standard iodine salt （ P 〈 0.05 ）. Conclusions Pregnant women in Quanshan District have adequate iodine intake, but 36.5% of them still suffer from iodine deficiency and 10.5% with excessive iodine intake. More information should be given about iodine deficiency disorders and more directions on diet. There should also be more iodine tests to ensure an optimal iodine intake among more women to guarantee a normal intelligent development of babies.
