摘要
目的了解璧山区8~10岁儿童和孕妇碘营养情况,为防治碘缺乏病提供科学依据。方法按重庆市璧山区东、西、南、北、中划分5个抽样片区,在每个片区随机抽取1所小学,在每所小学中随机抽取40名左右8~10岁儿童采集尿样。每个抽取小学所在镇街,抽样检测20名左右孕妇采集尿样。采集日间随意一次尿样,用砷铈催化分光光度法检测尿中碘含量。结果共采集8~10岁儿童尿样231份,平均尿碘中位数为299.52μg/L,尿碘含量在100μg/L以下为7.36%,100~200μg/L的为21.21%,200~300μg/L的为20.34%,300μg/L以上的为51.18%;不同性别的儿童的尿碘水平差别无统计学意义(χ2=5.891,P=0.117),不同年龄的儿童的尿碘水差别有统计学意义(χ2=13.232,P=0.04);共采集孕妇尿样102份,平均尿碘中位数为262.6μg/L,尿碘含量在150μg/L以下的为22.55%,150~250μg/L为34.31%,250~500μg/L为25.49%,500μg/L以上者为17.64%。结论璧山区儿童碘营养充足,存在着碘摄入过多,需要预防和控制尿碘含量过盛现象,降低食盐中的加碘量,同时孕妇人群中需要增加碘的摄入。
Objective To understand the iodine nutrition situation of children aged 8-10 years and pregnant women in Bishan area and provide scientific basis for prevention and treatment of iodine deficiency disorders.Methods According to Bishan district in the east,west,south and north,divided into five sampling areas,in each area randomly selected a primary school,and randomly selected 8-10 years old about 40 children collecting their urine samples in each primary school. At each town where the primary school located,collected urine samples of 20 pregnant women. A random urine sample was collected during the day,and the iodine content in the urine was measured by Cerium-cerium catalyzed spectrophotometry. Results A total of 231 samples of urine from 8 to 10 years old children were collected. The median urinary iodine was 299. 52 μg/L,the urinary iodine content was 7. 36% when below 100 μg/L,21. 21% in 100-200 μg/L,200-300 μg/L was 20. 34%,and above 300 μg/L was 51. 18%; There was no significant difference in urinary iodine level between children of different gender（ χ^2= 5. 891,P = 0. 117）. There was a significant difference in urinary iodine between children of different ages（ χ^2= 13. 232,P = 0. 04）. A total of 102 samples of pregnant women were collected,the average urinary iodine was 262. 6 μg/L,urinary iodine content of 150 μg/L below was 22. 55%,150-250 μg/L was 34. 31%,250-500 μg/L was25. 49%, and above 500 μg/L was 17. 64%.Conclusion Children in Bishan district,their iodine nutrition are sufficient,and there exists excessive iodine intake. It is needed to prevent and control urinary iodine content of the phenomenon of excessive,reduce the amount of iodine in the salt,while pregnant women need to increase iodine intake.
