摘要
目的 了解2018-2022年泸州市孕妇碘营养状况,为碘缺乏病防治提供依据.方法 按照《全国碘缺乏病监测方案》(2016版),采用多阶段分层整群随机抽样,采集孕妇随意尿样及其家中食盐样品,并测定碘含量.结果 共检测孕妇尿样、盐样各3 500份,尿碘中位数为155.3 μg/L;2019、2020年孕妇尿碘中位数低于其余年份(均P＜0.001);不同年龄组孕妇尿碘中位数差异无统计学意义(Z=-0.297,P=0.766);孕早期孕妇尿碘中位数高于孕中期和孕晚期孕妇(Z=3.195、3.068,P=0.001、0.002);各县(区)孕妇尿碘中位数差异有统计学意义(H=36.592,P＜0.001).盐碘中位数、碘盐覆盖率、碘盐合格率与合格碘盐食用率分别为26.6 mg/kg、99.57％、95.58％、95.71％.不同年份和县(区)的盐碘含量、碘盐覆盖率、碘盐合格率、合格碘盐食用率相比,差异均有统计学意义(均P＜O.05).结论 2018-2022年泸州市孕妇整体碘适宜,碘盐食用情况良好,符合国家消除碘缺乏病的标准,但孕妇仍存在碘缺乏风险.今后应继续做好碘营养状况监测工作并加强孕期合理碘营养宣传教育力度.
Abstract
Objective To explore the iodine nutritional status of pregnant women in Luzhou City from 2018 to 2022,so as to provide a basis for the prevention and control of iodine deficiency disorders.Methods According to the"National Monitoring Plan for Iodine Deficiency Disorders"(2016 edition),a multi-stage stratified cluster random sampling method was used to collect random urine samples from pregnant women and salt samples from their homes,and iodine content was measured.Results A total of 3 500 urine samples and 3 500 salt samples were tested.The median urinary iodine was 155.3 μg/L.In 2019 and 2020,the median urinary iodine of pregnant women was lower than in other years(all P＜0.001).There was no statistically significant difference in median urinary iodine among pregnant women in different age groups(Z=-0.297,P=0.766).The median urinary iodine in early pregnancy was higher than in mid-term and late-term pregnancy(Z=3.195,3.068;P=0.001,0.002).There were significant differences in median urinary iodine among pregnant women in different counties(districts)(H=36.592,P＜0.001).The median salt iodine,iodized salt coverage rate,iodized salt qualification rate and qualified iodized salt consumption rate were 26.6 mg/kg,99.57％,95.58％and 95.71％,respectively.The differences in salt iodine content,iodized salt coverage rate,iodized salt qualification rate and qualified iodized salt consumption rate among different years and counties(districts)were statistically significant(all P＜0.05).Conclusion Overall,the iodine nutritional status of pregnant women in Luzhou City from 2018 to 2022 was suitable,and the consumption of iodized salt was satisfied,meeting the national standards for eliminating iodine deficiency disorders.However,pregnant women still faced the risk of iodine deficiency.In the future,efforts should be continued to monitor iodine nutritional status and strengthen education on rational iodine nutrition during pregnancy.
