Iodine is a mineral categorized as a trace element. The majority of iodine in the body is located in the thyroid gland. Its primary function in the human body is the synthesis of hormones and the preservation of healthy thyroid activity. Iodine is crucial for the control of the immune system. It functions as an antioxidant, prooxidant, and possesses anti-inflammatory properties by modulating the release of cytokines and other inflammatory mediators. Iodine is mostly absorbed by the body via dietary sources, particularly iodized salt. The research aimed to investigate the dietary iodine intake in young adults, assess urinary iodine concentration in this demographic, explore the correlation between iodine concentration and inflammatory characteristics, analyze the relationship between iodine concentration and body composition, and evaluate the association between iodine concentration and anthropometric characteristics. The investigation involved 70 young adults aged 19 to 24, comprising 35 men and 35 women. Iodine metabolism disorders and confirmed thyroid diseases were exclusion criteria. Inflammatory and anthropometric parameters, body composition, urinary iodine concentration, and dietary iodine intake were examined. The median iodine concentration in the subjects’ urine is 120.77 µg/l, while the median dietary iodine intake is 624.66 µg. The median body mass index is 23.72 kg/m². The median body composition consists of 32.6% muscular tissue and 27.4% fat tissue. The median waist diameter is 75.5 cm, and the upper arm circumference is 27.8 cm. The median neutrophil-to-lymphocyte ratio is 1.5. No significant association between iodine levels in urine and any observed data was detected. The participants in this study exhibit an excessive dietary iodine intake and a urinary iodine concentration indicative of a population with adequate intake. No substantial correlation was seen between urinary iodine content and inflammatory, anthropometric, or body composition variables.

Key Words: iodine, inflammation, anthropometry, body composition.
