摘　　要：目的 掌握兰州市孕妇的碘营养水平,为防控碘缺乏导致的相关疾病提供合理依据。方法 采用多阶段随机抽样的方法抽取兰州市不同地区孕妇作为研究对象,收集研究对象的尿样和食盐样品,采用砷铈催化分光光度法(WS/T107.2006)测定尿样品中的碘含量,《制盐工业通用试验方法 碘的测定》(GB/T 13025.7)测定盐碘含量。结果 本次调查从800份孕妇家庭食用盐中检测出加碘盐741份,非碘盐6份,不合格碘盐53份,碘盐含量中位数为24.20 mg/kg;2019年兰州市孕妇尿碘中位数为157.20μg/L,不同地区孕妇尿碘水平之间的差异有统计学意义(H=9.29,P<0.01);不同孕期孕妇尿碘水平之间的差异有统计学意义(H=12.64,P<0.01);食用合格碘盐和食用不合格碘盐孕妇尿碘中位数分别为158.19μg/L和139.02μg/L,但差异无统计学意义;不同盐碘水平下不同尿碘水平孕妇的构成无差异。结论 兰州市总体孕妇碘营养水平适宜,部分地区孕妇碘营养水平低于适宜范围,孕妇食用不合格碘盐和非碘盐的情况仍在部分地区出现,应继续加强碘营养水平监测,指导科学补碘。Objective To master the iodine nutrition level in Lanzhou, and to provide scientific basis for the prevention and control of iodine deficiency disorders. Methods A multi-stage random sampling method was used to select pregnant women in Lanzhou City as research object. Urine samples and household salt samples were collected, and iodine content in urine samples was determined by arsenic-cerium catalytic spectrophotometry(WS/T107.2006). The determination of iodine content in salt was carried out according to General test method for salt industry-determination of iodine(GB/T 13025.7). Results A total of 800 household edible salt samples were monitored in this survey, including 741 iodized salt, 6 non-iodized salt and 53 unqualified iodized salt samples. The average iodized salt was 24.20 mg/kg. In 2019, the median of urinary iodine of pregnant women in Lanzhou City was 157.20 μg/L, and there were significant differences in urinary iodine levels among pregnant women in different regions(H=9.29, P<0.01). In 2019, there were significant differences in urinary iodine levels among pregnant women in different pregnancies in Lanzhou(H=12.64, P<0.01). The median of urine iodine of pregnant women who ate qualified iodized salt was 158.19 μg/L, while that of pregnant women who ate unqualified iodized salt was 139.02 μg/L. There was no statistically significant difference between the two. There was no significant difference in the composition ratio of different urine iodine levels at different salt iodine levels. Conclusion The iodine level of pregnant women in Lanzhou City is within the appropriate range, but the average urinary iodine level of pregnant women in some areas is below the appropriate range. There are still unqualified iodized salt and non-iodized salt in some areas, and there is a risk of iodine deficiency. People should continue strengthening the monitoring of iodine nutrition level and guide scientific iodine supplementation.
