A representative random sample comprising approximately 4000 Danes, 16-99 years old, were questioned as to present or previous psoriasis eruption by non-medical, professional interviewers. Based on the information obtained, the point prevalence for men was 4.2%, for women 3.3%. 88% of those who believed themselves to be suffering from psoriasis stated that they had been treated by doctors for psoriasis and 71% by dermatologists and/or dermatological departments. The difference found between men and women is not statistically significant. The actual prevalence has been adjusted according to an estimated overcalculation of some 25% based on the number of false-positive answers to questionnaires in a twin study. The prevalence for men is thus adjusted to 3.2% and for women to 2.5%. The number of adult psoriatics in Denmark is estimated at approximately 113,000, of whom 71,000 suffer from mild psoriasis and 42,000 from more severe psoriasis.
一个由大约4000名16至99岁丹麦人组成的代表性随机样本，接受了非医学专业访谈人员关于当前或既往银屑病发作情况的询问。根据所获得的信息，男性的现患率为4.2%，女性为3.3%。那些认为自己患有银屑病的人中，88%表示曾因银屑病接受过医生治疗，71%接受过皮肤科医生和/或皮肤科的治疗。男女之间的差异无统计学意义。根据一项双胞胎研究中问卷假阳性答案数量估计约25%的高估情况，对实际患病率进行了调整。因此，男性患病率调整为3.2%，女性为2.5%。丹麦成年银屑病患者数量估计约为113,000人，其中71,000人患有轻度银屑病，42,000人患有更严重的银屑病。
