title: Relationship between Biological Markers, Metabolic Components, Lifestyles, and Impaired Fasting Glucose in Male Workers.
abstract: BACKGROUND
  Confirmation regarding the association between impaired fasting glucose (IFG) and biomarkers in addition to metabolic components and lifestyle factors are required in the occupational filed for preventing diabetes mellitus.
  
  
  METHODS
  The study was performed in working men aged 30 to 60 years old, who were not taking medication for any metabolic diseases. The author measured the serum levels of high-sensitivity C-reactive protein (CRP), uric acid, and plasma fibrinogen as potential biomarkers of IFG.
  
  
  RESULTS
  The mean serum uric acid, log-transformed serum CRP, and plasma fibrinogen levels were higher in the subjects with IFG than in those without IFG. Multivariate analysis revealed significant associations between the presence of IFG and age, log-transformed value of serum CRP, increased waist circumference, hypertension, and hypertriglyceridemia, with odds ratios of 1.1 (95% confidence interval [CI], 1.08 to 1.1; P<0.001), 1.8 (95% CI, 1.4 to 2.3; P<0.001), 1.3 (95% CI, 1.09 to 1.7; P<0.01), 1.9 (95% CI, 1.6 to 2.3; P<0.001), and 1.3 (95% CI, 1.04 to 1.6; P<0.05), respectively, for the presence of IFG.
  
  
  CONCLUSIONS
  Serum CRP, age, and three metabolic components were associated with IFG. In contrast, there were no significant associations between IFG and lifestyle factors, serum uric acid or plasma fibrinogen.
