To describe the prevalence of erectile dysfunction (ED) in Hong Kong and identify the biopsychosocial correlates of ED.
This was a descriptive and analytic population-representative cross-sectional study of ED in Hong Kong. The study subjects were 1506 men aged 26 to 70 years, recruited by two-stage stratified random sampling, and interviewed face-to-face by trained interviewers with structured questionnaires.
The overall prevalence of ED was 36.7% (95% confidence interval [CI] 33.7 to 39.7). The age-specific prevalence rate was 18.3% (95% CI 11.1% to 25.4%), 28.6% (95% CI 23.5% to 33.6%), 37.9% (95% CI 32.3% to 43.5%), 47.3% (95% CI 40.1% to 54.5%), and 61.1% (95% CI 51.1% to 71.0%) for the age groups 26 to 30, 31 to 40, 41 to 50, 51 to 60, and 61 to 70 years, respectively. The severity of ED increased with age (P <0.01), and sexual satisfaction decreased with age (P = 0.01). Age (odds ratio [OR] 1.26, P <0.01), living on Hong Kong Island (OR 0.71, P = 0.04), General Health Questionnaire score (OR 1.03, P <0.01), current smokers of 30 or more cigarettes per day (OR 2.11, P = 0.05), and hours spent on work, housework, and self-study (OR 0.945, P = 0.03) were independently associated with ED.
To our knowledge, this is the first population-representative study of ED in Hong Kong. The prevalence and severity of ED increased with age, and we found biological (age), psychological (General Health Questionnaire), and social (smoking, Hong Kong district, "hours spent on work") factors to have independent influences on ED. The negative association between "hours spent on work" and ED is a novel finding. The results of this study have shown that Hong Kong has a high prevalence of ED compared with Western populations.
描述香港勃起功能障碍（ED）的患病率，并确定ED的生物心理社会相关因素。
这是一项对香港ED进行的具有人群代表性的描述性和分析性横断面研究。研究对象为1506名年龄在26至70岁之间的男性，通过两阶段分层随机抽样招募，并由经过培训的访谈员使用结构化问卷进行面对面访谈。
ED的总体患病率为36.7%（95%置信区间[CI]为33.7%至39.7%）。26至30岁、31至40岁、41至50岁、51至60岁和61至70岁年龄组的年龄特异性患病率分别为18.3%（95%CI为11.1%至25.4%）、28.6%（95%CI为23.5%至33.6%）、37.9%（95%CI为32.3%至43.5%）、47.3%（95%CI为40.1%至54.5%）和61.1%（95%CI为51.1%至71.0%）。ED的严重程度随年龄增加而增加（P<0.01），性满意度随年龄降低（P = 0.01）。年龄（优势比[OR]为1.26，P<0.01）、居住在香港岛（OR为0.71，P = 0.04）、一般健康问卷得分（OR为1.03，P<0.01）、每天吸烟30支或更多的现吸烟者（OR为2.11，P = 0.05）以及花在工作、家务和自学上的时间（OR为0.945，P = 0.03）与ED独立相关。
据我们所知，这是香港第一项具有人群代表性的ED研究。ED的患病率和严重程度随年龄增加而增加，并且我们发现生物（年龄）、心理（一般健康问卷）和社会（吸烟、香港地区、“花在工作上的时间”）因素对ED有独立影响。“花在工作上的时间”与ED之间的负相关是一个新发现。本研究结果表明，与西方人群相比，香港ED的患病率较高。
