Background: The reported associations between metabolic syndrome (MetS) and systemic vascular inflammation/insulin resistance prompted the author to determine the predictive ability of markers for MetS in the occupational field.
Methods: The study was performed in 3460 working men aged 30 to 64 years. The author measured the serum levels of high-sensitivity C-reactive protein and insulin as potential key biomarkers of MetS.
Results: Multivariate analysis revealed significant associations between the presence of MetS and the log-transformed value of serum insulin and log-transformed value of serum C-reactive protein, with odds ratios of 29.4 (95% confidence interval, 18.0 to 48.2; P < 0.001) and 1.87 (95% confidence interval, 1.47 to 2.38; P < 0.001) of these two markers, respectively, for the presence of MetS.
Conclusion: Elevated serum levels of insulin were found to be strongly associated with MetS in this cross-sectional study.
