2018~2023年南通市通州区孕妇尿碘的检测与结果分析
Detection and Results Analysis of Urine Io-dine in Pregnant Women in Tongzhou Dis-trict, Nantong City from 2018 to 2023

目的：掌握南通市通州区孕妇尿碘水平情况，探究检测过程中存在的问题，为孕妇补碘提供指导依据。方法：于2018~2023年间每年从全区随机抽取五个乡镇的孕妇采集尿样，按《WS/T107-2006尿中碘的砷铈催化分光光度测定法》检测尿中碘的含量，计算孕妇尿碘水平。结果：采集孕妇尿样603份，尿碘水平M(P₂₅, P₇₅)为108.60 (70.00, 153.40) μg/L，尿碘含量 < 150 μg/L、[150, 250) μg/L、[250, 500) μg/L、≥ 500μg/L的占比分别为73.96%、18.41%、6.97%、0.66%；不同年份尿碘分布构成差异有统计学意义(χ² = 78.627, P < 0.01)，不同孕期孕妇尿碘浓度差异有统计学意义(χ² = 15.352, P < 0.05)；结论：2018~2023年南通市通州区孕妇碘营养总体处于碘不足状态，需指导其科学增加饮食的碘营养摄入，提高其碘营养水平，保持在适宜水平。
Purpose: Grasp the urinary iodine level of pregnant women in Tongzhou District of Nantong city, ex-plore the problems existing in the testing process, and provide guidance for pregnant women to supplement iodine. Methods: From 2018 to 2023, urine samples were collected from pregnant women in five towns of iodine was detected according to the WS/T107-2006 Arseniccerium catalyt-ic spectrophotometric method for the determination of iodine in urine. Results: 603maternal urine samples were collected, urinary iodine level M (P₂₅, P₇₅) is 108.60 (70.00, 153.40) μg/L, The propor-tion of urinary iodine content < 150 μg/L, [150,250) μg/L, [250, 500) μg/L, ≥500 μg/L were 73.96%, 18.41%, 6.97% and 0.66%, respectively; the difference of urinary iodine distribution in different years (χ ² = 78.627, P < 0.01), and urinary iodine concentration in different pregnant (χ ² = 15.352, P < 0.05); conclusion: From 2018 to 2023, the iodine nutrition of pregnant women in Tongzhou Dis-trict of Nantong city is generally in a state of iodine deficiency, so it is necessary to guide them to scientifically increase the intake of dietary iodine nutrition, improve their iodine nutrition level, and keep it at an appropriate level.
