摘要

摘要: 目的通过分析2017年乌海市城区8~10岁儿童和孕妇碘缺乏病（iodine deficiency disorders，IDD）监测数据，了解其碘缺乏病现状和碘营养水平，为评价和调整碘缺乏病防控策略提供数据依据。方法以乌海市的海勃湾区、乌达区、海南区为监测点，每个监测点随机抽取200名8~10岁儿童和100名孕妇；采集尿样和户盐样，测定尿碘、盐碘；采用B超法测定儿童容积。结果儿童甲状腺肿大10人，肿大率为1.67%；碘盐覆盖率为99.56%，合格率为94.64%，盐碘中位数为21.7 mg/kg。儿童尿碘中位数为204.5 μg/L，尿碘 < 100 μg/L者占12.7%，尿碘 < 50 μg/L者占2.2%，男童尿碘中位数224.0 μg/L，高于女童191.5μg/L（P=0.004）。孕妇尿碘中位数为145.8 μg/L，尿碘 < 150 μg/L的孕妇占51.7%；孕早期尿碘中位数115.5 μg/L，尿碘 < 150 μg/L者占孕早期孕妇的62.0%。结论乌海市儿童碘营养水平较适宜，孕妇碘营养水平略低，应特别加强孕早期尿碘监测，纠正孕早期碘缺乏。

Abstract: Objective To explore current situation of iodine deficiency disorders(IDD) and iodine nutrient level by analyzing monitoring data of IDD from children aged from 8 to 10 and pregnant women in Wuhai City in 2017, so as to provide basis for the prevention and control of IDD. Methods Our surveillance points were located in Haibowan District, Wuda District, Hainan District of Wuhai City. Samples of salt and human urine were collected from 200 children aged 8 to 10 and 100 pregnant women at random. Urine iodine concentration and salt iodine concentration were measured. Thyroid volume was determined by B-ultrasound. Results There were 10 children diagnosed as thyroid goiter. Children's Goiter rate in this area was 1.67%.The averaged covering rate of eating iodine among children reached 99.56%, their acceptance rate of iodized salt was 12.7%. Median of salt-iodine was 21.7 mg/kg. Median of urinary iodine(MUI) for children was 204.5 μg/L. The percentage of children whose urinary iodine was less than 100 μg/L and 50 μg/L was 12.7% and 2.2%, respectively. Median of urinary iodine in boys was 224.0 μg/L, which was higher than in girls(191.5 μg/L), the difference was statistically significant(P=0.004). Median of urinary iodine in pregnant women was 145.8 μg/L. Pregnant women whose urine iodine below 150 μg/L accounted for 51.7%. The MUI in pregnant women during the first trimester was 115.5 μg/L. Pregnant women during the first trimester whose urine iodine below 150 μg/L accounted for 62.0%. Conclusions The iodine nutrition condition in children is basically normal, while iodine nutrition deficiency exist in pregnant women in this area. We should particularly enhance monitoring urinary iodine for pregnant women during the first trimester to reduce iodine deficiency.
