The association between dietary iodine consumption and body composition in Caucasian females between the ages of 18 to 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). 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. Analysis of variance (ANOVA) evaluated any significant differences between tertiles of iodine intake. ANOVA revealed no significant differences between iodine intake tertiles on percent lean body mass, percent body fat, and waist-to-hip ratio.
