OBJECTIVES: The objective of this study was to examine the associations between indices of liver insulin resistance (IR) and whole-body insulin sensitivity and different cardiovascular disease (CVD) risk factors. DESIGN AND SUBJECTS: A total of 8750 nondiabetic men (age 57.2 ± 7.1 years, body mass index 26.8 ± 3.8 kg m(-2) ) were included in this study from the population-based cross-sectional Metabolic Syndrome In Men (METSIM) cohort. Liver IR index and Matsuda insulin sensitivity index (ISI) were used as markers of liver IR and whole-body insulin sensitivity, respectively. Pearson correlation analysis was performed to examine the associations between these indices and various CVD risk factors. RESULTS: Total cholesterol (r = -0.088 vs. r = 0.020; P < 0.0019), high-sensitivity C-reactive protein (CRP) (r = 0.284 vs. r = -0.219; P < 0.0019) and total triglycerides (r = 0.507 vs. r = -0.477; P < 0.05) were more highly correlated with liver IR index than with Matsuda ISI. By contrast, Matsuda ISI was nominally more highly correlated with systolic and diastolic blood pressure (r = -0.234 and r = -0.275 vs. r = 0.202 and r = 0.239, respectively) compared to liver IR index. Furthermore, the variance explained by liver IR index was larger than that explained by Matsuda ISI for the majority of CVD risk factors measured. CONCLUSIONS: Liver IR index correlated more strongly than Matsuda ISI with levels of total cholesterol, CRP and triglycerides. Therefore, liver IR might be a significant indicator of CVD risk amongst men.
