The association between dietary iodine and body composition in Caucasian females between the ages of 18 and 60

The purpose of this study was to determine if there was an association between dietary iodine consumption and body composition in Caucasian females between the ages of 18 to 60. Spearman rank order correlation assessed the association between dietary iodine intake and body weight, percent lean body mass, percent body fat, waist‐to‐hip ratio, total body bone mineral density (TBBMD), and circulating concentrations of T3, T4, and thyrotropin stimulating hormone (TSH). Average iodine intake in this population (N=188) was 55.8 μg/day (RDA=150 μg/day). No significant association was found between iodine intake and body weight, percent lean body mass, percent body fat, waist‐to‐hip ratio, TBBMD, TSH, T3, or T4 (p>;.05). Analysis of variance (ANOVA) evaluated significant differences between tertiles of iodine intake: Group 1, ≤ 33rd percentile (n=113); Group 2, >; 33rd percentile and ≤ 66th percentile (n=12); and Group 3, >; 66th percentile (n=63). ANOVA revealed no significant differences between iodine intake tertiles on percent lean body mass, percent body fat, and waist‐to‐hip ratio. However, participants who had the highest iodine intake (Group 3, >; 66th percentile of the RDA) had the highest mean percent lean body mass (62.6%) and lowest mean percent of body fat (37.4%). Further research is warranted to use more sensitive measures of iodine status and body composition analyses.
