新疆碘缺乏重病区重点人群碘营养现状分析

目的 通过对乌什县和拜城县孕妇和哺乳妇女尿碘值的分析,了解新疆碘缺乏重病区重点人群的碘营养现状.方法 用过硫酸胺消化一砷铈催化分光光度测定法检测采集的孕妇和哺乳妇女的1次随意尿,用SPSS 15.0软件对检测结果进行统计分析.结果 共检测尿样338份,尿碘中位数为180.96g/L,四分位数间距为229.385g/L,50g,L的63份,占18.6%;100 g,L的121份,占35.8%;150g/L的150份,占44.4%;18.9%的孕妇、哺乳妇女尿碘在150～250g/L范围内.结论 新疆碘缺乏重病区有44.4%的重点人群碘营养不足,应因地制宜适时采取有效的、有针对性的补碘措施,以防止因碘缺乏而造成智力发育障碍.

Iodine nutrition status of the iodine deficiency population in the seriously endemic area of Xinjiang

Objective The study was conducted to determine the iodine nutrition status of the involved population in the seriously endemic area of iodine deficiency through urine iodine tests for pregnant and breast-feeding women in Wushi and Baicheng County. Methods Ammonium persulfate digestible-arsenic-cerium catalyzed spectrophotometry was used to detect single random urine of the pregnant women and lactating women, and the results were statistically analyzed using SPSSl5.0. Results A total of 338 urine samples were tested. As a result, the median urinary iodine was 180.96 μg/L, the inter-quartile range 229.385 μg/L. There were 65 samples with iodine 〈50 p~g/L, accounting for 18.6%; 121 samples with iodine 〈100 μg/L, accounting for 35.8%; and 150 samples with iodine 〈150 μg/L, accounting for 44.4%. 18.9% of pregnant and breastfeeding women had the urinary iodine in the range of ]50-250 μg/L. Conclusion A proportion of 44.4% of the key population had insufficient iodine nutrition in the iodine deficiency area of Xinjiang. Effective and targeted measures to supplement the iodine should be taken promptly in light of the local conditions to prevent mental retardation caused by iodine deficiency.
