Iodine Intake and Risk of Mortality: Evidence from a Nationally Representative Korean Cohort.

ABSTRACT: Background/Objectives: Iodine intake influences thyroid-related and metabolic diseases that have important public health implications. However, longitudinal evidence of the association between iodine intake and mortality remains scarce and limited to Western populations. Given the markedly high iodine intake among Asians and possible ethnic or regional differences in iodine sensitivity, population-based data from Asian cohorts are needed. Methods: We analyzed 5497 adults from the Korean National Health and Nutrition Examination Survey (2013-2015) linked with mortality follow-up through 2021. Urinary iodine concentration (UIC) was quantified from spot urine samples using inductively coupled plasma mass spectrometry. Iodine intake was estimated from UIC and categorized into fou
