目的了解北京市西城区育龄妇女碘营养状况,分析孕妇与非孕妇女的碘营养特点,为防治碘缺乏病提供工作依据。方法在社区及孕检机构收集研究对象1次随意尿样,使用“尿中碘的砷铈催化分光光度测定方法(WS/T107-2006)”测定尿液中碘的含量。结果测定孕妇236例,尿碘中位数为184.3μg/L,碘营养不足发生率为30.9%;非孕妇女200例,尿碘中位数为179.5μg/L,碘营养不足发生率为17.5%,孕妇与非孕妇女尿碘水平的总体分布差异无统计学意义(Z=-0.176,P=0.860);不同孕周孕妇尿碘水平的分布状况和非孕妇女比较,差异无统计学意义(P>0.05);两组人群在不同级别碘营养水平的分布不同(Z=-4.635,P<0.001)。结论北京市西城区育龄妇女碘营养总体处于适宜水平,孕妇及非孕妇女均存在碘营养不合理现象,碘缺乏和过量同时存在,在妊娠期合理补碘及进行多次动态尿碘监测很有必要。
Objective To understand the status of iodine nutrition in women of childbearing age in Xicheng District, Beijing, and to analyze the characteristics of iodine nutrition in pregnant women and non-pregnant women, so as to provide basis for prevention and treatment of iodine deficiency disorders. Methods A random urine sample was collected from community and pregnancy test institutions and the urinary iodine arsenic and cerium catalytic spectrophotometry (WS / T107-2006) was used to determine the content of iodine in urine. Results The median of urinary iodine was 184.3 μg / L in 236 pregnant women, the incidence of iodine deficiency was 30.9%. The number of non-pregnant women was 200, the median urinary iodine was 179.5 μg / L, and the incidence of iodine deficiency was 17.5 %. There was no significant difference in the distribution of urinary iodine between pregnant women and non-pregnant women (Z = -0.176, P = 0.860). There was no significant difference in the distribution of urinary iodine between pregnant women and non-pregnant women (P> 0.05). There were different distribution of iodine nutrition in different groups (Z = -4.635, P <0.001). Conclusion The iodine nutrition of women of childbearing age in Xicheng District of Beijing is generally at an appropriate level. Irrational iodine nutrition is unreasonable in pregnant women and non-pregnant women, and iodine deficiency and excess exist simultaneously. During pregnancy, iodine nutrition is reasonable and there are many dynamic urinary iodine monitoring necessary.
