沿海非高碘地区育龄妇女碘营养水平研究

目的探讨沿海非高碘盐地区育龄妇女的碘营养状况,为进一步制定碘缺乏病防治策略提供科学依据。方法收集碘盐覆盖率低的8个市（县）1 161名15～55岁的育龄妇女食用盐样和尿样,采用过硫酸氨消化-砷铈催化分光光度法测定尿碘,采用直接滴定法测定盐碘。结果8个市（县）1 161名妇女碘盐食用率为44.4%,尿碘中位数为120.0μg/L; 其中4.7%妇女尿碘中位数〈25μg/L为重度缺碘,15.5%妇女25μg/L〈尿碘中位数〈50μg/L为中度缺碘,23.1%妇女50μg/L〈尿碘中位数〈100μg/L为轻度缺碘,生育高峰时期的育龄妇女（15～35岁）尿碘水平最低为97.3μg/L。孕妇和哺乳期妇女严重碘缺乏的比例较高,分别为12.2%、11.9%,是非特殊生理时期妇女的2～3倍（χ^2=33.09,P〈0.001）。食用非碘盐的妇女引起严重碘缺乏是食用碘盐妇女的10倍（χ^2=209.52,P〈0.001）。育龄妇女的盐碘含量与尿碘水平有统计学线性相关（t=11.86,P〈0.001）,妇女碘缺乏与生活居住环境无统计学差异。结论育龄妇女,尤其是孕妇和哺乳期妇女,是碘缺乏病防治工作的重点人群,应加强育龄妇女的口服碘油丸强化工作。
