Several studies have reported that obesity and diabetes are important risk factors for elevated blood aminotransferase activity in individuals with no underlying causes of liver disease. The aim of this study was to determine whether obesity and fasting glucose level were associated with hepatic dysfunction in patients with hepatitis B infection. A total of 934 patients with hepatitis B infection were enrolled, among whom increased alanine aminotransferase (ALT) activity (>= 40 IU/L) was observed in 25.1%. By univariate analysis, factors associated with increased ALT activity among patients with hepatitis B infection included body mass index (BMI), fasting blood glucose level, and blood triglyceride and high-density cholesterol levels. By multivariate logistic regression analysis, BMI and fasting blood glucose level were independent predictors of elevated ALT activity, with odds ratios of 1.73 (95% confidence interval, 1.17-2.56) for subjects with a BMI greater than or equal to 25 kg/m(2) and 1.88(95% confidence interval, 1.06-3.33) for subjects with a fasting blood glucose greater than or equal to 126 mg/dL. Even in subjects with ALT activity within the reference range, ALT activity was found to be associated with BMI. In conclusion, a BMI greater than or equal to 25 kg/m(2) and a fasting blood glucose level greater than or equal to 126 mg/dL were risk factors for increased ALT activity in subjects with hepatitis B infection, suggesting that obesity and diabetic fasting hyperglycemia may aggravate liver injury in this population.
