title: [Comparison of incidence of BPH and related factors between urban and rural inhabitants in district of Wannan].
abstract: OBJECTIVE
  To investigate the difference of BPH incidence in two groups.
  
  
  METHODS
  309 cadres and 314 farmers over 60 years old in district of Wannan have been investigated. The investigation included prostate volume (V), IPSS, L, Qmax, residual urine (R) and dietary constituents.
  
  
  RESULTS
  The intake of animal protein in cadres is more than that in farmers (u = 24.10, P < 0.01), and the incidence rate of BPH is significantly higher (91.1% vs 11.8%, chi 2 = 24.64, P < 0.001). Logistic regression shows that the intake of animal protein has a parallel relationship with BPH.
  
  
  CONCLUSIONS
  In the district of Wannan, the incidence of BPH in cadres is significantly higher than that of farmers, and it may be correlated with the amount of animal protein intake.
