title: [Association of the serum testosterone level with metabolic syndrome in men].
abstract: OBJECTIVE
  To investigate the association of the serum testosterone (T) level with metabolic syndrome (MS).
  
  
  METHODS
  We enrolled in this investigation 1,006 men aged 30-60 years in Beijing and obtained the data on their blood pressure (BP), waist circumference (WC), fasting blood glucose (FBG), serum triglycerides (TG), high density lipoprotein-cholesterol (HDL-C) and serum testosterone (T). The men were divided into an MS group and a non-MS (NMS) group based on The Chinese Adult Dyslipidemia Prevention Guide 2007. The results were compared and analyzed.
  
  
  RESULTS
  There was no statistically significant difference between the ages of the two groups (P >0.05). Systolic BP (SBP), diastolic BP (DBP), WC, FBG and TG were significantly higher, while serum T and HDL-C remarkably lower in the MS than in the NMS group (P <0.001). The serum T level was markedly decreased with the increase of MS components (P <0.01). Both Pearson's correlation coefficients and multiple linear regression analyses showed that the serum T level was negatively correlated with age, WC, SBP and TG (P < 0.05).
  
  
  CONCLUSIONS
  Low serum T level may predict the development of MS in men.
