目的了解沿海、平原、山区的儿童、成人、哺乳期妇女和孕妇体内碘营养水平,掌握碘缺乏病防治效果。方法每种地区类型抽取儿童、成人各100名,哺乳期妇女、孕妇各50名,收集1次尿样进行碘含量检测。结果 3种地区的儿童和成人尿碘中位数均>100μg/L,沿海、平原地区的哺乳期妇女和孕妇中位数均>150μg/L,山区的哺乳期妇女和孕妇中位数分别为97.36μg/L、146.87μg/L;每类人群尿碘中位数在3种地区类型间的两两比较差异有统计学意义(P<0.05)。3种地区的儿童和成人尿碘频数分布主要集中在100μg/L~199μg/L;山区哺乳期妇女尿碘<100μg/L,所占比例为54.00%,高于沿海和平原(P<0.05);山区孕妇尿碘<150μg/L,所占比例为50.00%,与其他地区孕妇尿碘<150μg/L,所占比例比较,差异无统计学意义(P>0.05)。结论山区的哺乳期妇女和孕妇体内碘营养缺乏,受碘缺乏危害最严重,其他人群体内碘营养均充足。
Objective To understand the levels of iodine nutrition in children, adults, lactating women and pregnant women in coastal, plains and mountains, and to master the prevention and treatment of iodine deficiency disorders. Methods 100 children, 100 adults, 50 lactating women and 50 pregnant women were collected from each region. Urine samples were collected for iodine detection. Results The urinary iodine median of both children and adults was> 100μg / L in the three regions. The median lactation women and pregnant women in coastal and plain areas were both> 150μg / L. The median lactation women and pregnant women in mountainous areas were 97.36μg / L and 146.87μg / L respectively. There was significant difference in urinary iodine median among the three types of regions (P <0.05). The frequency of urinary iodine in children and adults in three kinds of areas mainly concentrated in the range of 100μg / L to 199μg / L. Urinary iodine was less than 100μg / L in lactating women in mountainous areas, accounting for 54.00%, higher than that in coastal and plain (P <0.05) ; Pregnant women in mountain area urinary iodine <150μg / L, the proportion of 50.00%, and other areas pregnant women urinary iodine <150μg / L, the proportion of the comparison, the difference was not statistically significant (P> 0.05). Conclusion Lack of iodine nutrition in lactating women and pregnant women in mountainous area is the most serious affected by iodine deficiency, while iodine nutrition is sufficient in other groups.
