目的：公共卫生已重新将注意力集中在弱势群体的低碘状况上。这项研究的目的是在实施强制性碘强化方案后，确定伊拉瓦拉地区母乳喂养妇女中与碘营养有关的知识和饮食习惯。方法：在四个幼儿中心进行横断面研究。60位母乳喂养前6个月的母亲完成了一份简短的知识问卷，一份针对碘的食物频率问卷，并报告了营养补充剂的使用情况。结果：女性在识别牛奶和面包等良好膳食碘来源方面的能力普遍有限，但45名女性（75%）正确地识别出海鲜是良好的碘来源。在确定与碘摄入不足有关的健康问题方面存在一些混淆。报告的平均碘摄入量为146毫克/天（标准偏差：58毫克；范围：43342毫克）；48名女性（80%）的摄入量低于190毫克/天的估计平均需求量。在对面包进行强化后，平均碘摄入量显著增加到182毫克/天（P < 0.001），摄入量低于估计平均需要量的妇女人数减少到36人（60%）。牛奶是碘摄入的最大来源，平均占碘摄入总量的62%。只有27名（45%）母亲报告服用含碘补充剂。结论：关于碘的知识不足和碘补充剂的有限使用的结合突出了一个潜在的公共卫生问题。然而，强制强化可能会克服这种知识和行为缺陷。
Aim: Public health has refocused attention on low iodine status of vulnerable groups. The purpose of this research was to identify knowledge and dietary practices related to iodine nutrition in breastfeeding women in the Illawarra region following introduction of the mandatory iodine fortification programme. Methods: A cross-sectional study was undertaken at four early childhood centres. Sixty mothers in their first six months of breastfeeding completed a short knowledge questionnaire, an iodine-specific food frequency questionnaire, and reported use of nutritional supplements. Results: The women were generally limited in their ability to identify good dietary sources of iodine such as milk and bread but 45 women (75%) correctly identified seafood as a good source. There was some confusion in identifying health problems associated with insufficient iodine intake. Mean reported iodine intake was 146 mg/day (standard deviation: 58 mg; range: 43342 mg); 48 women (80%) had intakes below the estimated average requirement of 190 mg/day. After allowance was made for fortification of bread, mean iodine intake significantly increased to 182 mg/day (P < 0.001) and the number of women having intakes below the estimated average requirement decreased to 36 (60%). Milk was the highest contributor to iodine intake, on average representing 62% of total iodine consumed. Only 27 (45%) mothers reported consuming supplements that contained iodine. Conclusion: The combination of inadequate knowledge regarding iodine and the limited use of iodine supplements highlights a potential public health issue of concern. However, mandatory fortification may be overcoming this knowledge and behaviour deficit.
