背景：虽然银屑病在世界范围内发生，但不同人群和地区之间的患病率差异很大。在中国，1987年进行了一项基于银屑病的研究，发现银屑病的患病率为0.12%。从那时起，没有大规模的，基于人群的研究报告。目的：获得中国银屑病患病率的准确数据。方法：在6个城市进行了以人群为基础的调查。采用整群抽样的方法，在每个城市中选择社区。受试者被要求在面对面的访谈中填写自我报告问卷，并接受皮肤科医生的体格检查。结果：共调查19,974人，其中17,345人完成问卷调查并接受皮肤科检查。银屑病102例（0.59%）。标准化后，银屑病患病率为0.47%。银屑病患病率男性为0.54%，女性为0.44%。97.06%的患者患有寻常型银屑病。28.43%的患者有银屑病家族史。59.80%的患者生活质量受到负面影响。结论：这项基于人群和皮肤科医生证实的研究表明，中国银屑病的患病率为0.47%，高于1987年报道的患病率。
Background: Although psoriasis occurs worldwide, the prevalence varies considerably between different peoples and regions. In China, a questionnaire-based study was carried out in 1987 and the prevalence of psoriasis was found to be 0.12%. Since then, no large-scale, population-based study has been reported. Objectives: To obtain the accurate figures for the prevalence of psoriasis in China. Methods: A population-based survey was conducted in 6 cities. The cluster sampling method was used to select communities in each city. The subjects were required to fill out self-reporting questionnaires during a face-to-face interview and also received physical examination by dermatologists. Results: 19,974 subjects were visited and 17,345 completed the questionnaires and received dermatological examination. 102 subjects (0.59%) were found to have psoriasis. After standardization, the prevalence of psoriasis was 0.47%. The prevalence of psoriasis in males and females was 0.54% and 0.44% respectively. 97.06% of the patients had psoriasis vulgaris. 28.43% of the patients reported a family history of psoriasis. 59.80% of patients experienced a negative influence on the quality of life. Conclusions: This population-based and dermatologist-confirmed study showed that the prevalence of psoriasis in China is 0.47%, which is higher than that reported in 1987.
