There is a lack of nationwide epidemiologic survey data on the prevalence estimate of erectile dysfunction (ED) in Chinese men living on the mainland China.
To attain the representative prevalence estimate of ED in the Chinese male population and to analyze potential risk factors associated with ED by demographics, socioeconomic status, and medical comorbidities.
The study was community based. The five-item Internation Index of Erectile Function questionnaire and in-person interview were used to obtain data. The survey subjects were 5,210 non-institutionalized Chinese men at least 40 years old residing in 30 provinces and autonomies of China. Multiple logistic regression analysis was used to disclose risk factors associated with ED.
The prevalence estimate of ED was 40.56% in Chinese men at least 40 years old.
The prevalence of ED increased with increasing age. A significant high prevalence of ED was observed in men who smoked heavily, were estranged from a partner, had diabetes, and lower urinary tract symptoms from benign prostatic hyperplasia. Smoking more than 30 cigarettes daily and obesity (body mass index ≥ 30 kg/m) significantly increased the risk for ED by multivariable-adjusted odds ratios. Stable or erratic sexual partners, personal incomes, alcohol consumption, and cardiovascular and/or cerebrovascular diseases were not risk factors associated with ED prevalence. Other sexual problems commonly seen in this group of men included difficulty achieving erectile rigidness, ejaculation, and climax during intercourse.
Knowledge on the prevalence of ED and its associated risk factors will help physicians in the clinical management and prevention of ED with the use of counseling for lifestyle adjustment and drug therapy.
Data on the influence of psychological conditions on ED were not collected. ED was not categorized as minor, moderate, or severe for analysis during processing of data.
The national representative prevalence of ED was determined for the first time in the Chinese male population. Zhang X, Yang B, Li N, Li H. Prevalence and Risk Factors for Erectile Dysfunction in Chinese Adult Males. J Sex Med 2017;14:1201-1208.
目前，中国大陆地区男性人群中勃起功能障碍（ED）的流行率尚无全国性的流行病学调查数据。
旨在获得中国男性人群中 ED 的代表性流行率，并通过人口统计学、社会经济状况和合并症分析与 ED 相关的潜在危险因素。
本研究采用社区为基础的方法，使用国际勃起功能指数问卷的 5 个项目和面对面访谈来获取数据。调查对象为中国 30 个省、自治区和直辖市的 5210 名非机构化 40 岁以上的中国男性。采用多因素逻辑回归分析揭示与 ED 相关的危险因素。
中国至少 40 岁的男性中 ED 的流行率估计为 40.56%。
ED 的患病率随年龄的增长而增加。大量吸烟、与伴侣分居、患有糖尿病和良性前列腺增生导致的下尿路症状的男性中 ED 的患病率显著升高。每日吸烟超过 30 支和肥胖（体重指数≥30kg/m）显著增加了 ED 的多变量调整优势比。稳定或不稳定的性伴侣、个人收入、饮酒和心血管/或脑血管疾病并不是 ED 流行的危险因素。这组男性中常见的其他性问题包括在性交过程中难以获得勃起硬度、射精和高潮。
了解 ED 的流行率及其相关危险因素将有助于医生在临床管理和预防 ED 中，通过生活方式调整和药物治疗咨询来帮助患者。
没有收集有关心理状况对 ED 影响的数据。在处理数据时，ED 没有分为轻度、中度或重度进行分析。
这是首次在中国男性人群中确定全国代表性的 ED 流行率。
