title: [Differences in the risk factors for clinical benign prostatic hyperplasia between the Mongolian and the Han people].
abstract: OBJECTIVE
  To define the differences in the risk factors for clinical benign prostatic hyperplasia (BPH) between the Mongolian and the Han people.
  
  
  METHODS
  Between January 2003 and June 2005, 63 Mongolian and 63 Han patients with BPH were interviewed using a questionnaire consisting of the risk factors for BPH.
  
  
  RESULTS
  The intake of alcohol and dairy products was higher in the Mongolians than in the Hans (P <0.05). The consumption of milk tea, dairy products and meat was significantly greater in the Mongolians ( >250 g per day) than in the Hans (P <0.01). And there were more smokers (the smoking index >300) with moderate to severe symptoms (IPSS > 7) in the Mongolians than in the Hans (85.71% vs 57. 14%, P <0.01). The incidence of intraprostatic chronic inflammation and calcification within the prostate gland was higher in the Mongolians (28% vs 11% , P < 0.05; 36.5% vs 15.87% , P < 0.01, respectively). No significant difference was observed between the two groups in body mass, blood pressure, marriage age, offspring number, physical activity, IPSS score and PSA level.
  
  
  CONCLUSIONS
  Compared with Han BPH patients, the Mongolian BPH patients had greater alcohol intake, higher protein diet and higher incidence of intraprostatic chronic inflammation, and those with the smoking index greater than 300 were more likely to receive surgical treatment.
