Long-term association of cardiovascular risk factors with impaired insulin secretion and insulin resistance.
The study aim was to investigate the association of cardiovascular risk factors with insulin resistance and impaired insulin secretion in an 8-year prospective population study in nondiabetic subjects. Cardiovascular risk factors of 271 subjects aged 16 to 61 years were measured at baseline, and insulin sensitivity and acute-phase insulin secretion were assessed by an intravenous glucose tolerance test (IVGTT) and Bergman's minimal model 8 years later. In logistic regression analysis, baseline high-density lipoprotein (HDL) and very-low-density lipoprotein (VLDL) cholesterol (P < .001 and P = .006, respectively), total, low-density lipoprotein (LDL), and VLDL triglycerides (P = .004, P = .048, and P = .002, respectively), apolipoprotein A1 (P = .010), and uric acid (P < .001) were associated with insulin resistance after adjustment for age and the body mass index (BMI). Systolic blood pressure (P = .042) and VLDL cholesterol (P = .018) were associated with impaired insulin secretion after adjustment for age and the BMI. This 8-year longitudinal study demonstrates that dyslipidemia, high blood pressure, and uric acid are associated with insulin resistance, whereas high systolic blood pressure and VLDL cholesterol are associated with impaired first-phase insulin secretion.
