摘要
目的了解2015—2019年天津市孕妇碘营养状况,为今后孕妇科学补碘提供理论依据。方法在天津市16个区中随机抽取6939名孕妇,采集孕妇尿样和家中食用盐并进行检测。结果共检测孕妇家庭食用盐6939份,碘盐覆盖率为81.78%,合格碘盐食用率为66.85%,盐碘中位数为25.96 mg/kg。共检测孕妇尿碘6938份,孕妇的碘营养水平(154.26μg/L)整体上是适宜的,但存在地区分布不平衡现象(郊区<城区,郊区孕晚期<城区孕晚期,郊区非高龄<城区非高龄)。Spearman相关分析发现尿碘与盐碘、碘盐覆盖率均呈正相关(P均<0.05)。食用未加碘食盐孕妇尿碘水平低于食用合格碘盐者(P<0.05)。结论天津市碘盐两率仍未达到国家消除碘缺乏病的标准,虽然孕妇尿碘中位数总体达到适宜水平,但郊区孕妇尿碘水平明显低于城区,且孕早期、郊区(孕早期、孕晚期)、食用未加碘食盐孕妇尿碘水平仍处于碘营养不足水平。因此,今后仍需继续加强孕妇碘营养监测,加强重点人群宣传推广科学食用合格加碘盐,为制定孕妇科学补碘政策提供依据。
Objective To understand the iodine nutrition status of pregnant women in Tianjin from 2015 to 2019,and to provide a theoretical basis for pregnant women′s scientific iodine supplement in the future.Methods A total of 6939 pregnant women were randomly selected from 16 districts in Tianjin.The urine samples and home salt of the pregnant women were collected to test iodine content.Results The iodine content was determined in a total of 6939 household salt samples of the pregnant women.The coverage rate of iodized salt was 81.78%,the consumption rate of qualified iodized salt was 66.85%,and the median salt iodine content was 25.96 mg/kg.A total of 6938 urine samples were determined for iodine content.The median urinary iodine of the pregnant women(154.26μg/L)reached an appropriate level of iodine nutrition,but there was an imbalance in the regional distribution(suburbsurban areas,pregnant women in the third trimester of suburbspregnant women in the third trimester of urban areas,and non-elderly pregnant women in the suburbsnon-elderly pregnant women in the suburban areas).Spearman correlation analysis found that urinary iodine was positively correlated with salt iodine and the coverage rate of iodized salt(all P<0.05).The urinary iodine level in pregnant women who consumed uniodized salt was lower than the level in those who consumed qualified iodized salt(P<0.05).Conclusion The coverage rate of iodized salt and the consumption rate of qualified iodized salt in Tianjin had not yet reached the national standard for eliminating iodine deficiency disorders.Although the median urine iodine level of pregnant women generally reached an appropriate level,the level of pregnant women′s urinary iodine in the suburbs was significantly lower than that in urban areas.The urinary iodine level of pregnant women in the first trimester,suburban areas(pregnant women in the first and third trimester)and pregnant women who consumed uniodized salt were still in the iodine deficiency level.Therefore,it is necessary to continue to strengthen the monitoring of pregnant women′s iodine nutrition,strengthen the promotion of scientific consumption of qualified iodized salt in key populations,and provide a basis for formulating a scientific iodine supplementation policy for pregnant women.
