To investigate the relationship between liver function and thyroid function tests in men with overweight and obesity. Body-mass-index (BMI), relative-fat-mass (RFM), Fibrosis-4-index (FIB-4), hepatic-steatosis-index (HSI), fatty-liver-index (FLI), albumin-bilirubin-grade (ALBI), and triglyceride-glucose-index (TyG-index) were used to perform a correlation study on liver and thyroid functions in the male participants with overweight/obesity.
We utilized data from the National Health and Nutrition Examination Survey (NHANES) 2011-2012. We performed correlation analysis to examine these relationships.
This study enrolled 811 male participants, including 263 lean and 548 individuals with overweight/obesity based on BMI. Analysis showed that 133 subjects had RFM of < 22.8%, while 678 were overweight/obese. Significant positive correlations were found between liver function markers (ALT, AST, GGT) and thyroid hormones (fT3, tT3), as well as between non-invasive liver indices (HSI and FLI for steatosis, ALBI for function and prognosis, and FIB-4 for fibrosis risk) and thyroid function parameters. ALBI was positively correlated with globulin, BMI, and tT4, and it had significant negative correlation with tT3, fT3, fT4, total protein, ALT, and AST. FIB-4 was positively correlated with TSH, and tT4 (p = 0.0026, and 0.0147, respectively). It had significant negative correlation with tT3, fT3, and BMI (p = 0.0122, < 0.0001, and 0.0008, respectively). FIB-4 had significant weak correlation with TSH in euthyroid subjects (r = 0.077 and p = 0.034).
In this study, several non-invasive liver indices were significantly associated with thyroid function parameters in men with obesity. Indices may assist in identifying individuals at higher risk of liver-thyroid dysfunction, though prospective studies are needed to confirm their utility.
