【摘要】 目的通过检测深圳市孕妇尿碘水平,评价深圳市孕妇的碘营养状况,为科学补碘和防治碘缺乏病提供依据。方法在每个区东、西、南、北、中5个方位各随机抽取1个街道(不足5个时全部抽取),在所抽取的每个街道各随机抽取20名孕妇(每个区尿样不低于100份),检测尿碘,计算尿碘中位数。结果共采集检测孕妇尿碘600份,其中位数为154.3μg/L,四分位数区间为89.5~248.4μg/L。尿碘含量<150μg/L有290份,占48.4%;150~249μg/L有161份,占26.8%;250~500μg/L有98份,占16.3%;>500μg/L有51份,占8.5%。各区孕妇尿碘水平、不同孕期孕妇碘水平差异无统计学意义。结论深圳市孕妇碘营养总体处于适宜水平,但有2个区尿碘中位数<150μg/L,提示轻度碘营养不足,有必要推出含碘量更高的孕妇专用盐。更多还原

【Abstract】 [Objective]To evaluate the iodine nutrition level of pregnant women in Shenzhen City by detecting the urinary iodine,provide basis for scientific iodine supplement and control of iodine deficiency disorders. [Methods]1 sub-district was respectively sampled from the direction of east,west,north,south and middle of each district(all sub-districts were enrolled in the study when there were 4 or less sub-districts in the district),and 20 pregnant women were collected from each sub-district(not less than 100 samples in each district),to detect urinary iodine and calculate the median. [Results]Totally 600 urine samples of pregnant women were collected,the median of urinary iodine was 154.3 μg/L,and the inter-quartile range was 89.5-248.4 μg/L. There were290 samples with the urinary iodine less than 150 μg/L,accounting for 48.4%,161 samples with the urinary iodine of 150-249 μg/L,accounting for 26.8%,98 samples with the urinary iodine of 250-500 μg/L,accounting for 16.3%,and 51 samples with the urinary iodine more than 500 μg/L,accounting for 8.5%. The difference in level of urinary iodine of pregnant women was not statistically significant among different districts,and the difference in level of urinary iodine was not statistically significant among pregnant women in different stage. [Conclusion]The iodine nutrition of pregnant women is appropriate in Shenzhen City. However,the median of urinary iodine is less than 500 μg/L in two districts,which indicates there is mild iodine deficiency. It is necessary to provide edible salt which contains higher level of iodine for pregnant women.更多还原
