Background: Metabolic-associated fatty liver disease (MAFLD) is a spectrum of liver diseases linked to insulin resistance (IR), type 2 diabetes, and metabolic disorders. IR accelerates fat accumulation in the liver, worsening MAFLD. Regular physical activity and weight loss can improve liver function, reduce fat, and lower cardiovascular risk. This study examines the role of sex hormone-binding globulin (SHBG) in MAFLD, focusing on its potential as a biomarker and its relationship with insulin resistance. Methods: The study included 98 male patients (ages 30–55) with MAFLD, identified through systematic examinations, and 74 healthy male controls. All participants underwent abdominal ultrasound and blood tests after fasting, assessing markers such as glucose, liver enzymes (AST, ALT, γGT), lipids (cholesterol, triglycerides), insulin, SHBG, estradiol, and testosterone. SHBG levels were analyzed in relation to body mass index (BMI) and age. Results: A significant association was found between low SHBG levels and the presence of fatty liver. Individuals with MAFLD had lower SHBG levels compared to controls. BMI and age were key factors influencing SHBG, with higher BMI linked to lower SHBG in younger men, while SHBG remained stable in older individuals regardless of BMI. Conclusion: SHBG may serve as a valuable biomarker for early detection and risk assessment of MAFLD. The complex relationship between SHBG, BMI, and age highlights the importance of considering both hormonal and metabolic factors when assessing fatty liver risk. Our findings support the need for comprehensive metabolic evaluations in clinical practice.
