OBJECTIVS: To examine the dietary intake of iodine in young adults, to determine the concentration of iodine in urine in young adults, to examine the relationship between iodine concentration and inflammatory features, to examine the relationship between iodine concentration and body composition, and to examine the relationship between iodine concentration and anthropometric characteristics. STUDY DESIGN: A cross-sectional study. PARTICIPANTS AND METHODS: Young adults between the ages of 19 and 24, of both sexes, were included in the study. The sample size is 70, of which 35 are men and 35 are women. Exclusion criteria were iodine metabolism disorder and diagnosed thyroid disease. Inflammatory and anthropometric characteristics, body composition, iodine concentration in urine and dietary iodine intake were analyzed. RESULTS: 70 subjects participated in the research. The median iodine concentration in urine is 120,77 µg/L, and the median dietary iodine intake is 624,66 µg. The median body mass index is 23,72 kg/m2 . Body composition, which includes the percentage of muscle and fat tissue, is a median of 32,6 % for muscle tissue and 27,4 % for fat tissue. The median waist circumference is 75,5 cm, and the median upper arm circumference is 27,8 cm. The median neutrophil-to-lymphocyte ratio has a value of 1,5. No significant association was observed between iodine concentration in urine and any measured parameter. CONCLUSION: The subjects of this research have an excessive dietary iodine intake. The subjects have a concentration of iodine in their urine that corresponds with sufficient intake. No significant correlation of iodine concentration in urine with inflammatory and anthropometric characteristics and body composition was found.
