摘要

背景：在澳洲及紐西蘭，建議在麵包中強制添加碘鹽，以解決重新浮現的碘缺乏情況。欲瞭解強化政策的影響，首先需要那些易缺乏族群的碘狀況之基本資料。目的：評估健康婦女的碘營養狀況以及調查消費者對強制加碘計畫的認知及態度。研究設計：在新南威爾士州的臥龍岡市，藉由便利性取樣，共取得78位20-55歲的非懷孕婦女為橫斷性的樣本。搜集一次24小時尿液樣本以檢測尿液中碘的濃度。利用自填式問卷來評估消費者對加碘強化的認知、觀念及態度。結果：尿液中碘濃度的中位數為56 μg/L（四分位數間距為41-68），表示有輕微的碘缺乏。少於一半的人明瞭碘營養缺乏與不良懷孕有關，顯示對碘的知識不足。健康教育及補充碘，特別是經由醫療工作者的介入，被認為是改善低碘濃度的最佳策略。結論：新南威爾士州的一個地區，婦女的碘營養狀況是不良的。這些資料更佳支持需要全國性的政策，以解決碘的攝取問題，這其中也包括消費者教育活動。

Background: Mandatory fortification of bread with iodised salt is proposed to address the re-emergence of iodine deficiency in Australia and New Zealand. The impacts of fortification require baseline data of iodine status among vulnerable sectors of the population. Objective: To assess the iodine status of healthy women and to investigate consumer understanding and attitudes related to the proposed mandatory iodine fortification programme. Design: Cross-sectional sample of 78 non-pregnant women aged 20-55 y was conveniently sampled in Wollongong, NSW. A single 24-hr urine sample was collected for urinary iodine concentration (UIC). A self-administered questionnaire assessed consumer understanding, perceptions and attitudes related to iodine fortification. Outcomes: Median UIC = 56 μg/L (IQR = 41-68), indicating mild iodine deficiency. Knowledge about iodine was poor with less than half associating low iodine status with adverse pregnancy outcomes. Health education and supplementation, particularly at the medical practitioner interface, was considered the best strategy for improving low iodine levels. Conclusions: The iodine status of women in one region of New South Wales was low. These data add support to the need for a national approach to address iodine intake which includes an accompanying consumer education campaign.
