摘　　要：目的了解重庆市合川区重点人群食用盐碘含量和碘营养摄入水平,为相关部门掌握全区重点人群碘营养变化趋势,坚持“因地制宜、分类指导、科学补碘”的策略,适时采取针对性措施和策略,为预防碘缺乏和碘过量提供科学依据。方法按照分层抽样方法,每年抽取合川区200名8~10岁儿童和100名孕妇,采集其食用盐、尿液样品进行食用盐碘、尿碘含量监测。结果2019—2023年合川区重点人群碘盐覆盖率、碘盐合格率、合格碘盐食用率均大于95.0%,盐碘含量中位数为25.2 mg/kg,四分位数间距为22.9~27.9 mg/kg,不同片区盐碘含量分布差异无统计学意义(H=5.57,P>0.05),孕妇盐碘含量高于儿童盐碘含量(Z=-2.09,P<0.05)。8~10岁儿童尿碘中位数为202μg/L,尿碘含量处于适宜范围的儿童仅占34.2%,碘缺乏占14.7%,超适宜量占33.2%,碘过量占17.9%,男性儿童和女性儿童尿碘含量总体分布差异无统计学意义(H=-1.42,P>0.05)。孕妇尿碘中位数为172μg/L,碘营养处于适宜水平仅占36.8%,碘缺乏占38.0%,超适宜量占19.6%,过量占5.5%。儿童尿碘含量高于孕妇尿碘含量(Z=-4.05,P<0.05)。结论重庆市合川区碘盐普及程度较高,分布均匀稳定,但儿童存在碘摄入过量的风险,而孕妇存在碘摄入不足的风险。建议调整重庆市食盐加碘标准,针对孕妇、哺乳期妇女等特需人群,提供高碘含量的专供盐。Objective To understand the iodine content of edible salt and iodine nutritional intake levels in Hechuan District of Chongqing,so as to provide scientific evidence for the relevant departments to grasp the trend of iodine nutrition changes among key populations in the region,to adhere to the strategy of adapting to local conditions,guiding classification,and scientifically supplementing iodine,to take targeted measures and strategies in a timely manner for preventing iodine deficiency and excess.Methods According to the stratified sampling method,200 children aged 8-10 and 100 pregnant women in Hechuan District were selected annually for monitoring their salt and urine iodine levels.Results The coverage rate of iodized salt,qualified rate of iodized salt,and consumption rate of qualified iodized salt among key populations in Hechuan District from 2019 to 2023 were all greater than 95.0%.The median salt iodine content was 25.2 mg/kg,and the interquartile range was between 22.9 and 27.9 mg/kg.There was no statistically significant difference in the distribution of salt iodine content in different regions(H=5.57,P>0.05).The salt iodine content of pregnant women was higher than that of children(Z=-2.09,P<0.05).The median urine iodine of children aged 8-10 years old was 202μg/L.Only 34.2%of children had moderate urinary iodine levels,14.7%were iodine deficient,33.2%were above the appropriate level,and 17.9%were iodine excess.There was no statistically significant difference in the distribution of urinary iodine content between male and female children(H=-1.42,P>0.05).The median urine iodine of pregnant women was 172μg/L.Only 36.8%of pregnant women were at an appropriate level,38.0%were iodine deficient,19.6%were above the appropriate level,and 5.5%were excessive.The urine iodine content of children was higher than that of pregnant women(Z=-4.05,P<0.05).Conclusion The popularization of iodized salt in Hechuan District of Chongqing is relatively high,with a uniform and stable distribution.But children have the risk o
