Abstract Background Epidemiologic findings suggest that measures of body fat distribution predict health outcomes independent of the overall body fat assessed by body mass index (BMI). This study aimed to evaluate the associations of overall and regional body fat with the severity of hepatic steatosis and fibrosis in type 2 diabetic patients with non‐alcoholic fatty liver disease. Methods Bioelectric impedance analysis and two newly developed anthropometric indices, namely, A Body Shape Index (ABSI) and Body Roundness Index (BRI), were used to estimate the body fat. Based on fibroscan parameters, significant hepatic fibrosis and severe steatosis were defined as ≥F2 and >66%, respectively. Results Higher total body fat (odds ratio OR 1.107, 95% confidence intervals (CI) 1.038–1.182, p = 0.002), trunk fat (OR 1.136, 95% CI 1.034–1.248, p = 0.008) and leg fat (OR 1.381, 95% CI 1.139–1.674, p = 0.001) were associated with liver fibrosis. However, in contrast to the total body fat (OR 1.088, 95% CI 1.017–1.164, p = 0.014) and leg fat (OR 1.317, 95% CI 1.066–1.628, p = 0.011), the trunk fat was not associated with severe hepatic steatosis. BRI performed better than trunk, leg and total body fat in predicting hepatic steatosis (OR 2.186, 95% CI 1.370–3.487, p = 0.001) and fibrosis (OR 2.132, 95% CI 1.419–3.204, p 0.05). Conclusion BRI revealed a superior predictive ability for identifying the degree of hepatic steatosis and stiffness than other obesity indices. Additionally, higher levels of adiposity in the trunk, legs, and overall body were linked to an increased risk of developing liver fibrosis. Although trunk fat did not show an association with severe hepatic steatosis, an increase in leg and total fat was related to liver steatosis.
