Introduction. Many patients with non-alcoholic fatty liver disease (NAFLD) have impaired glucose regulation or type 2 diabetes mellitus (DM). We investigated characteristics of NAFLD patients associated with hyperglycemia. Methods. During a 2-hour oral glucose tolerance test (OGTT), serum glucose and insulin were measured in 152 NAFLD patients. Results. 48.7% of NAFLD patients had hyperglycemia. Age (odds ratio , 95% confidence interval (CI): 1.03–1.13), body mass index (BMI) ( , 95% CI: 1.01–1.25), and lower high-density lipoprotein cholesterol (HDL-C) ( , 95% CI: 0.92–0.98) proved to be independent predictors of hyperglycemia. After OGTT, 30 min insulin was lower in hyperglycemic patients ( versus μIU/ml, ), while 90 min insulin ( versus μU/ml, ) and 120 min insulin ( versus μIU/ml, ) were higher. Conclusions. NAFLD patients with higher BMI, lower HDL-C, or older age were more likely to have impaired glucose metabolism. An OGTT could be of value for early diagnosis of DM among this population.
