Iodine deficiency still remains a major public health concern worldwide despite global progress in its elimination. The aims of the present study were to evaluate dietary iodine status in the mother and one adult member of each family and the association between mothers' knowledge, attitude and behaviour and the dietary iodine status of adult family members in Tehran.
In this cross-sectional study, 24 h urinary iodine and Na concentrations and the iodine content of household salt were measured. Mothers' knowledge, attitude and behaviour were assessed using a questionnaire administered in face-to-face interviews.
Health-care centres from four distinct areas of Tehran.
Mother-adult family member pairs aged ≥ 19 years (n 290), enrolled through randomized cluster sampling.
In mothers and adult family members, median 24 h urinary iodine concentration was 73 (interquartile range (IQR) 36-141) µg/l and 70 (IQR 34-131) µg/l, dietary iodine intake was 143 (IQR 28-249) µg/d and 130 (IQR 26-250) µg/d and dietary salt intake was 8.0 (IQR 5.9-10.2) g/d and 7.5 (IQR 5.3-10.0) g/d, respectively. Significant correlations were observed between mothers' attitude and behaviour and the 24 h urinary iodine concentration, dietary iodine intake and iodine content of salt of adult family members. In multiple analysis, lower quartiles of salt iodine content and salt intake and inappropriate behaviour scores in mothers increased the risk of urinary iodine concentration <100 µg/l in adult family members.
The present study showed that mothers' behaviour, but not knowledge and attitude, was among major contributors to the suboptimal dietary iodine status observed in adult family members.
尽管在消除碘缺乏方面取得了全球性进展，但碘缺乏仍是全球主要的公共卫生问题之一。本研究旨在评估母亲及其每个家庭的一名成年成员的膳食碘状况，以及母亲的知识、态度和行为与成年家庭成员膳食碘状况之间的关系。
在这项横断面研究中，测量了 24 小时尿碘和 Na 浓度以及家用盐的碘含量。通过面对面访谈使用问卷评估母亲的知识、态度和行为。
德黑兰四个不同地区的医疗保健中心。
年龄≥ 19 岁的母亲-成年家庭成员对（n 290），通过随机聚类抽样纳入。
在母亲和成年家庭成员中，24 小时尿碘中位数分别为 73（四分位距（IQR）36-141）μg/l 和 70（IQR 34-131）μg/l，膳食碘摄入量分别为 143（IQR 28-249）μg/d 和 130（IQR 26-250）μg/d，膳食盐摄入量分别为 8.0（IQR 5.9-10.2）g/d 和 7.5（IQR 5.3-10.0）g/d。母亲的态度和行为与成年家庭成员的 24 小时尿碘浓度、膳食碘摄入量和盐的碘含量之间存在显著相关性。在多因素分析中，母亲的盐碘含量和盐摄入量的较低四分位数以及不适当的行为评分会增加成年家庭成员尿碘浓度<100μg/l 的风险。
本研究表明，母亲的行为，而不是知识和态度，是导致成年家庭成员膳食碘状况不佳的主要因素之一。
