GPT and Insulin resistance: Serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were associated with insulin resistance in univariate analysis (R = 0.54, p < 0.0001 and R = 0.36, p = 0.001, respectively) and after adjustment for age, gender and waist circumference (partial R = 0.43, p = 0.0001 and partial R = 0.37, p = 0.001, respectively).
