简要总结
Mild-to-moderate iodine deficiency remains a problem in many parts of the world, including Norway. Of particular concern are fertile, pregnant, and lactating women. The Norwegian Dairy Council developed a digital iodine-specific food frequency questionnaire (I-FFQ) for the assessment of iodine intake levels, but it has yet to be validated. The main objective was thus to investigate the relative validity of the I-FFQ by comparing estimates of iodine intake obtained from the I-FFQ against a single 24-hour recall (24HR) and urinary iodine concentration (UIC) in fertile women.
