Abstract

Objective To undemtand the rhythm of urinary iodine level of children aged 8-10 in Chongqing city.Methods In April 2008,using the stratified random sampling method,we sampled 60 children aged 8-10 in a lodging primary school in Chongqing(20 per age group,half male and half female),the urine samples were collected in the morning and at 10:00,12:30,16:00,iodine in urine was detected by method of Ce and arsenic catalytic speetrophotometry(WS/T 107-2006).The difference of the urinary iodine level was compared by age,sex and time of day.Results The median urinary iodine of 60 children was 265.07μg/L on the overall.Irrespective of the stratification factors,excluding morning urinary iodine(366.75μg/L)and urinary iodine at 10:00(338.30 μg/L),the urinary iodine between 12:30(235.15μg/L)and 16:00(251.50μg/L)was not significant(all P>0.05),statistically significant differences(all P 0.05).The 9-year-old group's urinary iodine were not significantly different between morning urine(366.15μg/L)and 10:00(368.10 μg/L),and between 12:30(244.00 μg/L)and 16:00(186.30 μg/L,all P>0.05),significant differences were faund at other times of the day(all P 0.05 ), followed by rapid decline to 16: 00 (269.35 μg/L), and compared with the morning urine and 10:00, there was significant difference(all P 0.05). Conclusions The change of urinary iodine level in children aged 8 - 10 was not obvious before noon, changes can be seen in the afternoon.Urinary iodine level before 10:00 is indicative.

重庆市8 ~ 10岁儿童尿碘水平节律性研究

目的了解重庆市8 ~ 10岁儿童尿碘水平的变化规律。方法2008年4月，采用分层随机抽样方法，对重庆市某寄宿小学8 ~ 10岁儿童60名(每年龄组各20名，男女各占1 / 2)，分别于上午、10:00、12:30、16:00采集尿样，采用Ce、砷催化分光光度法(WS/T 107-2006)检测尿碘含量。尿碘水平的差异按年龄、性别和一天中的时间进行比较。结果60例患儿尿碘中位数为265.07μg/L。在不考虑分层因素的情况下，除上午尿碘(366.75μg/L)和10:00尿碘(338.30 μg/L)外，12:30(235.15μg/L)与16:00(251.50μg/L)尿碘差异均不显著(P>0.05)，差异均有统计学意义(P均0.05)。9岁组晨尿碘(366.15μg/L)与10:00(368.10 μg/L)、12:30(244.00 μg/L)与16:00(186.30 μg/L，均P>0.05)差异无统计学意义，其余时间差异均有统计学意义(均P>0.05)，随后迅速下降至16:00(269.35 μg/L)，与晨尿、10:00比较，差异均有统计学意义(均P>0.05)。结论8 ~ 10岁儿童尿碘水平在中午前变化不明显，下午才有变化。十点前的尿碘水平是指示性的。关键词:碘;尿;节奏
