This study assessed the iodine knowledge of pregnant and lactating women and the relationship to dietary iodine intake and iodine status. The factors influencing iodine intake were analysed.
Basic information and iodine knowledge were collected via a questionnaire. A FFQ assessed dietary iodine intake. The urinary iodine concentration (UIC) was measured using the arsenic-cerium catalytic spectrophotometric determination of iodine in urine (WS/T 107 -2016).
A cross-sectional study involving pregnant and lactating women in Xinjiang, China was conducted.
A total of 1181 pregnant women and 504 lactating women were enrolled in the study.
The median UIC for pregnant and lactating women was 179·27 and 192·81 µg/l, respectively, and the dietary iodine intake was 407·16 and 356·89 µg/d, respectively. Of the pregnant and lactating women, 73·4 % and 82·5 % had medium iodine knowledge, respectively. In pregnant women, iodine knowledge and dietary iodine intake were positively correlated. High iodine knowledge and iodine education were shown to be protective factors for excessive iodine intake in pregnant women.
This study demonstrated that the iodine nutritional status of women in Xinjiang was appropriate, and iodine knowledge was at a medium level, but there was confusion about iodine nutrition. Public education is needed to improve iodine knowledge and active iodine supplementation awareness among these populations of women.
本研究评估了孕妇和哺乳期妇女的碘知识水平，以及其与膳食碘摄入量和碘营养状况的关系。分析了影响碘摄入量的因素。
通过问卷调查收集基本信息和碘知识。使用食物频率问卷评估膳食碘摄入量。采用砷铈催化分光光度法（WS/T 107-2016）测定尿碘浓度（UIC）。
在中国新疆进行了一项孕妇和哺乳期妇女的横断面研究。
共纳入 1181 名孕妇和 504 名哺乳期妇女。
孕妇和哺乳期妇女的 UIC 中位数分别为 179.27 和 192.81 µg/l，膳食碘摄入量分别为 407.16 和 356.89 µg/d。分别有 73.4%和 82.5%的孕妇和哺乳期妇女具有中等碘知识水平。在孕妇中，碘知识与膳食碘摄入量呈正相关。高碘知识和碘教育被证明是孕妇碘摄入过多的保护因素。
本研究表明，新疆妇女的碘营养状况适宜，碘知识处于中等水平，但对碘营养存在混淆。需要开展公众教育，提高这些妇女群体的碘知识水平和积极补碘意识。
