目的 了解濂溪区居民食盐盐碘水平和碘营养水平,为持续消除碘缺乏病和合理补碘提供科学依据。方法 在辖区东、西、南、北、中5个方位选取5个乡镇,每个乡镇各抽取8~10岁儿童40人、孕妇20人,采集家中食用盐盐样和调查对象尿液标本,检测盐碘含量和尿碘含量,并对检测结果进行统计分析。抽取的儿童甲状腺进行检查。结果 共检测食用盐盐样300份,盐碘中位数为24.0 mg/kg,碘盐覆盖率为96.7%,合格碘盐食用率为93.7%。 8～10岁儿童尿碘中位数为211.4 μg/L,尿碘＜50 μg/L占1.0%,尿碘值＜100 μg/L占14.5%,100~299 μg/L占56.5%,≥300 μg/L占29.0%。孕妇尿碘中位数为160.9 μg/L,尿碘频数＜150 μg/L占46.0%,150~249 μg/L占32.0%,250~499 μg/L占19.0%,≥500 μg/L占3.0%。8~10岁儿童没有甲状腺肿大病例。结论 濂溪区8～10岁儿童和孕妇碘营养总体处于适宜状态,存在部分儿童碘摄入过量和部分孕妇碘摄入不足的问题。

Objective To understand the salt iodine level and iodine nutrition level of Lianxi District residents,and to provide scientific basis for the continuous elimination of iodine deficiency disorders and rational iodine supplement. Methods Forty children aged 8~10 years and 20 pregnant women were selected from five towns in the east,west,south,north and middle of the district.Edible salt and urine samples were collected to detect the content of salt iodine and urine iodine,and the detection results were statistically analyzed.Thyroid examination was performed on the sampled children. Results A total of 300 edible salt samples were tested with a median salt iodine level of 24.0 mg/kg,an iodized salt coverage rate of 96.7%,and a qualified iodized salt consumption rate of 93.7%.The median of urinary iodine in 8~10 years children was 211.4 μg/L,with urinary iodine level＜50 μg/L accounting for 1.0%,＜ 100 μg/L accounting for 14.5%,100~299 μg/L accounting for 56.5%,≥300 μg/L accounted for 29.0%.The median urinary iodine of pregnant women was 160.9 μg/L,with urinary iodine level ＜ 150 μg/L accounting for 46.0%,150-249 μg/L accounting for 32.0%,250~499 μg/L accounting for 19.0%,≥500 μg/L accounting for 3.0%.There was no goiter case in children aged 8-10 years. Conclusion The iodine nutrition of children aged 8-10 years and pregnant women in Lianxi District is generally in an appropriate state.However,there is a problem of excessive iodine intake in some children and insufficient iodine intake in some pregnant women.
