AB  - OBJECTIVE: To investigate the relationship of prostate-specific antigen (PSA) 
      with age in men older than 50 years in Beijing. METHODS: A cross-sectional study 
      was performed in men aged over 50 years at communities in Beijing, and serum 
      total PSA (T-PSA) and free PSA (F-PSA) levels were assayed. The relationship 
      between age and PSA was analyzed with simple linear regression. RESULTS: A total 
      of 1 027 subjects were enrolled. Serum T-PSA and F-PSA levels were positively 
      correlated with age (r=0.208,P<0.001; r=0.230, P<0.001), whereas F/T ratio wasn't 
      correlated with age (r=0.055, P>0.079). The upper limit (95% CI) for serum PSA: 
      1.55 mug/L for 50-59 years, 2.08 mug/L for 60-69 years, 2.40 mug/L for 70-79 years, 
      3.52 mug/L for >/=80 years. CONCLUSION: Of the men aged over 50 years in Beijing, 
      there is a positive correlation between serum T-PSA, F-PSA and age; whereas F/T 
      ratio isn't correlated with age.
