【 摘 要 】

AbstractObjectiveIodine 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.DesignIn 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.SettingHealth-care centres from four distinct areas of Tehran.SubjectsMother–adult family member pairs aged ≥19 years (n 290), enrolled through randomized cluster sampling.ResultsIn 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
