The occurrence of psoriasis in a Norwegian Lapp population was estimated by reviewing medical records in the local health centre of Kautokeino. Altogether 40 cases of psoriasis were registered in the study population comprising 99.6% of the total population of 2,963 individuals. Thirty-five cases of psoriasis belonged to the Lappish population of 2,508 people, giving a prevalence of 1.4%, with no difference between males and females. Five cases of psoriasis were found in the non-Lappish population of 442 individuals which gives a prevalence of 1.1% with no sex differences. A peak prevalence among Lapps was observed in the age groups 20-39 years (2.7%), equal for both sexes and in females aged 50-59 years (3.2%), whereas a lower prevalence of 0.6% was found in the age group 40-49 years. A seronegative psoriatic arthritis was recorded in 6 of the 35 Lappish compared to none of the non-Lappish cases. A familial association was confirmed in 11 of the 35 Lappish cases, in none of the non-Lappish.
通过查阅考托凯努当地健康中心的医疗记录，估算了挪威萨米族人群中银屑病的发病率。在包含2963人总人口99.6%的研究人群中，共登记了40例银屑病病例。35例银屑病病例属于2508人的萨米族人群，患病率为1.4%，男女之间无差异。在442人的非萨米族人群中发现了5例银屑病病例，患病率为1.1%，无性别差异。萨米族中，20 - 39岁年龄组患病率最高（2.7%），男女相同；50 - 59岁女性患病率为3.2%；而40 - 49岁年龄组患病率较低，为0.6%。35例萨米族病例中有6例记录为血清阴性银屑病关节炎，非萨米族病例中无一例。35例萨米族病例中有11例证实有家族关联，非萨米族病例中无一例。
