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).
Conclusion: 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.
