摘要
目的分析2020年兰州市8~10岁儿童和孕妇的碘营养状况。方法收集2020年兰州市重点人群碘缺乏病的监测数据,内容包括兰州市所辖三县五区的部分儿童和孕妇摄入的食用盐中碘化物(以下称“盐碘”)、尿中碘化物(以下称“尿碘”)及儿童甲状腺容积指标,统计分析不同人群各指标水平和差异。结果2020年2410份盐样中,盐碘平均水平为(26.35±4.65)mg/L,碘盐覆盖率为99.54%,合格碘盐食用率为91.16%;1610名受调查8~10岁儿童的尿碘中位数[M(P_(25),P_(75))]为208.95(139.45,285.68)μg/L,其中298份(18.51%)尿碘浓度大于300μg/L;儿童甲状腺肿大率(甲肿率)为0.74%;不同县区、不同年龄、不同性别间儿童甲状腺容积差异具有统计学意义(χ^(2)=100.10、χ^(2)=92.81、Z=3.19,P<0.05)。800份孕妇尿样中尿碘M(P_(25),P_(75))为166.75(105.51,253.98)μg/L,尿碘浓度小于150μg/L的有320份(40.00%);不同孕期尿碘平均水平差异无统计学意义(χ^(2)=0.31,P>0.05);不同孕期尿碘水平的构成差异无统计学意义(χ^(2)=6.63,P>0.05)。结论2020年兰州市8~10岁儿童及孕妇碘营养水平总体适宜,存在儿童碘营养过剩和孕妇碘营养缺乏迹象。
Objective To analyze the iodine nutritional status in pregnant women and children aged 8 to 10 years in Lanzhou in 2020.Methods The surveillance data of iodine deficiency disorders were collected from key populations in Lanzhou in 2020,which included iodides in edible salt(salt iodine),iodides in urine(urine iodine),and pediatric thyroid volume indices of pregnant women and children in five districts and three counties in Lanzhou.A statistical analysis was performed on the levels of and differences in these indices in different populations.Results A total of 2410 salt samples were collected in 2020.The mean salt iodine level was 26.35±4.65 mg/L,the iodized salt coverage rate was 99.54%,and the qualified iodized salt intake rate was 91.16%.The median urine iodine concentration[M(P_(25),P_(75))]of 1610 investigated children aged 8 to 10 years was 208.95(139.45,285.68)μg/L,among which 298 samples(18.51%)had a urine iodine concentration greater than 300μg/L.The incidence rate of goiter in children was 0.74%.There were significant differences in thyroid volume among children of different districts/counties,ages,and sexes(χ^(2)=100.10,χ^(2)=92.81,Z=3.19,P<0.05).The M(P_(25),P_(75))value of urine iodine of 800 urine samples from pregnant women was 166.75(105.51,253.98)μg/L,and the urine iodine concentration was less than 150μg/L in 320 samples(40.00%).There was no significant difference in the mean urine iodine level in different durations of pregnancy(χ^(2)=0.31,P>0.05).There was no significant difference in the composition of urine iodine levels in different durations of pregnancy(χ^(2)=6.63,P>0.05).Conclusion In 2020,the iodine nutritional level was generally appropriate in pregnant women and children aged 8 to 10 years in Lanzhou,but iodine excess in children and iodine nutritional deficiency in pregnant women were observed.
