The purpose of this study was to investigate the relationships of thyroid hormones with muscle and bone in euthyroid patients with T2DM. METHODS: This cross-sectional study included 344 euthyroid T2DM patients. Muscle mass and bone mineral density were measured by dual-energy X-ray absorptiometry. The levels of thyroid-stimulating hormone (TSH), free triiodothyronine (FT3), and free thyroxin (FT4) were measured by electrochemiluminescence immunoassay. RESULTS: The results revealed that FT3 was positively correlated with body mass index (BMI) in male patients after age correction. In men, FT4 was negatively correlated with body weight, BMI, total muscle mass, appendicular skeletal muscle mass (ASM), and ASM index (ASMI), while FT3/FT4 was positively correlated with body weight, BMI, total muscle mass, ASM, and ASMI after age correction. In women, FT4 was negatively correlated with ASM and ASMI, while FT3/FT4 was positively correlated with ASM and ASMI after age correction. FT3/FT4 was significantly lower in men with low muscle mass than in those with normal muscle mass. The age-adjusted odds for incident low muscle mass comparing the lowest and highest FT3/FT4 increased in men. CONCLUSIONS: FT3/FT4 was positively correlated with ASM and ASMI in both men and women. Therefore, FT3/FT4 may be a parameter indicative of low muscle mass in euthyroid men with T2DM. CI - (c) The Author(s), 2022.
