北京市社区中老年男性性功能调查报告：BPC-BPH研究结果

Prevalence of aging male sexual dysfunction in Beijing： the result from a community-based cross-sectional survey of BPC-BPH study group

目的调查北京市社区中老年男性性欲低下、勃起功能障碍（ED）、射精障碍的患病情况。方法采用分层多阶段整群不等比例随机抽样方法选择北京市15个社区1656名年龄≥50岁男性作为调查对象，分别记录国际勃起功能问卷（IIEF-5）评分及男性性功能问卷（O’Leary1995），应用X^2检验分析结果。结果符合标准的调查对象共1644人。年龄50～93（64．5±9．8）岁。平均IIEF-5（9．4±8．6）分。以IIEF-5评分0～21诊断为ED，总ED患病率90．45％，性欲低下60．04％，射精障碍38．81％。各年龄组（10岁／组）间ED、性欲低下、射精障碍患病率差异有统计学意义（P〈0．0001），各年龄组间不同程度ED患病率差异有统计学意义（P〈0．0001）。趋势检验表明随年龄增加，ED、性欲低下、射精障碍患病率逐渐增加（Z=10．1，P〈0．0001），与年龄呈正相关性。结论随年龄增加ED、性欲低下、射精障碍的患病率逐渐增加，ED患病率最高。

Objective To investigate the prevalence of aging male sexual dysfunction in Beijing. Methods A cross-sectional study was performed based on community of Beijing in men aged over 50 years old. The International Index of Erectile Function-5（IIEF-5）, Brief Male Sexual Function Inven- tory for Urology （O＇leary 1995） were recorded and analyzed. Results 1644 subjects were enrolled and the mean age was 64.5 years （range 50-93 years）. The mean score of IIEF-5 was 9.4：1：8.6. The prevalence of erectile dysfunction （ED）, defined as IIEF-5 between 0-21, was 90.45%. The incidence of reduction of sexual desire and defective ejaculation was 60.04% and 38. 81%, respectively. There was positive correlation between the prevalence of ED, reduction of sexual desire, defective ejaculation and age.
