This is a report of a population-based cross-sectional observational study in Western Australia (WA) on male erectile dysfunction (ED).
To assess the prevalence of ED in WA and to examine its associated sociodemographic factors.
Postal questionnaires were sent to randomly selected age-stratified male population samples obtained from the WA Electoral Roll.
In addition to items covering sociodemographic and clinical information, the Australian Standard Classification of Occupations (ASCO), the Socioeconomic Index for Area (SEIFA), and the 5-item International Index of Erectile Function (IIEF-5) were used.
One thousand seven hundred seventy (41.9%) of 4,228 questionnaires were returned. One thousand five hundred eighty (89.3%) were completed questionnaires from men aged 20.1 to 99.6 years (mean 57.9, median 59.1, standard deviation 18.5). The prevalences of any ED and of severe ED among adult males in WA, adjusted for age distribution, were 25.1 and 8.5%, respectively. Standardized to World Health Organization (WHO) World Standard Population, the corresponding prevalences were 23.4 and 7.4%. Prevalence, as well as severity, of ED increased with age. Thirty-eight percent of the participants who were married or had partners experienced ED (severe ED 19.1%). The prevalence of ED was not significantly different between "white-collar" and "blue-collar" workers. Despite the great majority of the affected participants having experienced ED for >1 year, only 14.1% reported having ever received any treatment for ED.
The study has provided population-based epidemiological data on ED in Western Australian men covering a wide range of ages. The finding that ED is age related, highly prevalent, and grossly underdiagnosed and undertreated is pertinent to global population aging and a rapidly aging Australian population. To facilitate comparisons across populations with different age distributions, all future population-based studies on ED should be standardized to WHO World Standard Population.
这是一项基于西澳大利亚州（WA）男性勃起功能障碍（ED）的人群横断面观察性研究报告。
评估西澳大利亚州勃起功能障碍的患病率，并研究其相关的社会人口学因素。
向从西澳大利亚州选民名册中随机抽取的按年龄分层的男性人群样本邮寄调查问卷。
除了涵盖社会人口学和临床信息的项目外，还使用了澳大利亚职业标准分类（ASCO）、地区社会经济指数（SEIFA）以及5项国际勃起功能指数（IIEF-5）。
4228份调查问卷中有1770份（41.9%）被退回。1580份（89.3%）是年龄在20.1至99.6岁（平均57.9岁，中位数59.1岁，标准差18.5）男性填写完整的问卷。经年龄分布调整后，西澳大利亚州成年男性中任何程度勃起功能障碍和重度勃起功能障碍的患病率分别为25.1%和8.5%。按照世界卫生组织（WHO）世界标准人口进行标准化后，相应患病率分别为23.4%和7.4%。勃起功能障碍的患病率及严重程度均随年龄增长而增加。已婚或有伴侣的参与者中有38%经历过勃起功能障碍（重度勃起功能障碍为19.1%）。“白领”和“蓝领”工人中勃起功能障碍的患病率无显著差异。尽管绝大多数受影响的参与者经历勃起功能障碍已超过1年，但只有14.1%的人报告曾接受过任何勃起功能障碍治疗。
该研究提供了西澳大利亚州不同年龄段男性勃起功能障碍基于人群的流行病学数据。勃起功能障碍与年龄相关、患病率高且诊断严重不足和治疗不足这一发现，与全球人口老龄化以及澳大利亚人口迅速老龄化相关。为便于比较不同年龄分布人群的数据，未来所有基于人群的勃起功能障碍研究均应按照世界卫生组织世界标准人口进行标准化。
