目的了解漯河市8~10岁儿童碘营养状况。方法抽样采集2012-2014年漯河市8~10岁儿童尿样,按照国标方法检测尿碘含量并进行统计分析。结果 2012~2014年儿童尿碘中位数分别为220.5、282.6、355.7μg/L,尿碘浓度≥300μg/L的比例分别为30.23%(39/129)、44.50%(89/200)、60.62%(117/193),差异具有统计学意义(χ~2=29.44,P<0.005)。8、9、10岁儿童尿碘中位数分别为264.5、297.4、314.3μg/L。男、女性儿童尿碘中位数分别为291.4、279.6μg/L。城镇、农村儿童尿碘中位数分别为222.9、338.0μg/L。结论漯河市8~10岁儿童整体碘营养状况良好,但仍有不足和过量现象,今后要继续加强儿童碘营养状况监测,科学调整干预措施,促进儿童健康成长。 Objective To understand the iodine nutrition status of children aged 8 ~ 10 in Luohe City. Methods The urine samples from 8 to 10 years old children aged from 2012 to 2014 in Luohe City were collected by sampling and the urinary iodine contents were measured and statistically analyzed. Results The median urinary iodine was 220.5,282.6,355.7 μg / L in children from 2012 to 2014, and the urinary iodine concentration was more than 300 μg / L in 30.23% (39/129), 44.50% (89/200) and 60.62 % (117/193), the difference was statistically significant (χ ~ 2 = 29.44, P <0.005). The median urinary iodine of children aged 8, 9 and 10 were 264.5, 297.4 and 314.3 μg / L, respectively. The urinary iodine median of male and female children were 291.4 and 279.6 μg / L, respectively. Urinary iodine in urban and rural children were 222.9 and 338.0 μg / L, respectively. Conclusion The overall iodine nutrition status of children aged 8-10 in Luohe City is good, but there are still insufficient and excessive iodine. In the future, we should continue to strengthen the monitoring of children’s iodine nutrition status and adjust the intervention measures to promote the healthy growth of children.
