title: [Prevalence of prostatic hyperplasia and its relative factors in six cities of China in 1997].
abstract: OBJECTIVE
  To study crude prevalence and distribution of the elderly prostatic hyperplasia.
  
  
  METHODS
  Three thousand three hundred and sixty-one elderly aged 60 years and above in the urban and rural areas of Beijing, Shanghai, Guangzhou, Chengdu, Xi'an and Shenyang were investigated, using clustered random sampling methods.
  
  
  RESULTS
  The crude prevalence of prostatic hyperplasia was found to be 43.68% with an increase with ageing (P < 0.01). The crude prevalence rates of prostatic hyperplasia among the elderly of 60-, 65-, 70-, 75-, 80-, 85- years old were 34.48%, 40.27%, 46.77%, 51.44%, 57.32% and 60.19% respectively (P < 0.01). Rates in the urban and rural areas were 46.79%and 39.64% respectively. The crude prevalence of urban areas was higher than that of rural areas (P < 0.01) and was found higher in Beijing (63.28%) and Guangzhou (54.28%), (P < 0.01). The crude rates prevalence of managers (54.88%), teachers and business men (55.17%) were in general higher than the prevalence of the workers (41.29%) and peasant (37.26%). Logistic regression analysis showed that the crude prevalence was related to ageing, profession and residential areas (P respective < 0.01).
  
  
  CONCLUSIONS
  The prevalence of prostatic hyperplasia was higher in the elderly and became a common disease of the male elderly in China. Prevention and treatment of prostatic hyperplasia in the elderly should be strengthened.
