We searched for published studies on the prevalence of erectile dysfunction (ED) in Asian populations, through Medline, PubMed, PsychInfo and scanned through reference lists. Data on prevalence rates were obtained and summarized for each Asian region, and were used to calculate pooled prevalence estimates using fixed and random effects models. As significant heterogeneity existed in certain age group categories, the random effects model was preferred. Twenty general population studies were identified. Six studies were eligible to be entered into the pooling of results, and provided 8653 subjects for analysis. The prevalence of ED increased with age. Pooled random effects age-specific prevalence rates were 15.1% (12.2-18.1), 29.6% (19.7-39.6), 40.6% (23.6-57.7), 54.3% (36.0-72.6) and 70.0% (62.3-77.7) for age groups 20-29, 30-39, 40-49, 50-59 and 60-69 years, respectively. Homogeneity of results in age groups 20-29 and 60-69 years suggested equally low and high prevalences of ED across Asian regions in these age groups, respectively. The overall reported prevalence in individual studies ranged from 2 to 81.8%. Prevalence rates and related information were summarized for each Asian region and for each study.
我们通过医学在线（Medline）、医学期刊数据库（PubMed）、心理学文摘数据库（PsychInfo）搜索了关于亚洲人群勃起功能障碍（ED）患病率的已发表研究，并浏览了参考文献列表。获取并汇总了每个亚洲地区的患病率数据，并使用固定效应模型和随机效应模型来计算合并患病率估计值。由于某些年龄组存在显著异质性，因此优先选择随机效应模型。共确定了20项一般人群研究。其中6项研究符合结果合并的条件，共提供了8653名受试者用于分析。ED的患病率随年龄增长而增加。20 - 29岁、30 - 39岁、40 - 49岁、50 - 59岁和60 - 69岁年龄组的随机效应合并年龄特异性患病率分别为15.1%（12.2 - 18.1）、29.6%（19.7 - 39.6）、40.6%（23.6 - 57.7）、54.3%（36.0 - 72.6）和70.0%（62.3 - 77.7）。20 - 29岁和60 - 69岁年龄组结果的同质性表明，在这些年龄组中，亚洲各地区ED的患病率分别同样较低和较高。个别研究报告的总体患病率范围为2%至81.8%。汇总了每个亚洲地区和每项研究的患病率及相关信息。
