英国曼彻斯特大学Rosa Parisi团队分析了国家/地区和全球范围内银屑病的流行病学。2020年5月28日，该研究发表在《英国医学杂志》上。

为了系统回顾并提供有关银屑病发病率的信息，并对全球、国家/地区特定银屑病的流行率进行估计，研究组在Medline，Embase，科学引文索引等大型数据库中检索从建库到2019年10月的文献，筛选出报告一般人群银屑病发率或患病率的研究，并进行系统审查和荟萃分析。

最终共有168项研究符合纳入标准。银屑病的患病率从东亚的0.14％到大洋洲的1.99％不等。西欧（1.92%）、中欧（1.83%）、北美（1.50%）和拉丁美洲南部高收入人群（1.10%）的银屑病患病率也很高。

总之，世界上有81％的国家缺乏有关银屑病流行病学的信息。该病在成年人中比在儿童中更常见。银屑病在各个地区分布不均；在高收入国家和人口较多的地区更为普遍。

Abstract: Objective To systematically review and provide information on the incidence of psoriasis and quantify global, regional, and country specific estimates of its prevalence.

Design Systematic review and meta-analysis.

Data sources Medline, Embase, Web of Science, SciELO, Korean Journal Databases, Russian Science Citation Index, WPRIM, SaudiMedLit, Informit, IndMed, and HERDIN were searched systematically from their inception dates to October 2019.

Methods Studies were included if they reported on the incidence or prevalence of psoriasis in the general population. Incidence data were summarised descriptively, whereas bayesian hierarchical models were fitted to estimate the global, regional, and country specific prevalence of psoriasis.

Results 41164 records were identified and 168 studies met the inclusion criteria. The prevalence of psoriasis varied from 0.14% (95% uncertainty interval 0.05% to 0.40%) in east Asia to 1.99% (0.64% to 6.60%) in Australasia. The prevalence of psoriasis was also high in western Europe (1.92%, 1.07% to 3.46%), central Europe (1.83%, 0.62% to 5.32%), North America (1.50%, 0.63% to 3.60%), and high income southern Latin America (1.10%, 0.36% to 2.96%).

Conclusions Eighty one per cent of the countries of the world lack information on the epidemiology of psoriasis. The disease occurs more frequently in adults than in children. Psoriasis is unequally distributed across geographical regions; it is more frequent in high income countries and in regions with older populations. The estimates provided can help guide countries and the international community when making public health decisions on the appropriate management of psoriasis and assessing its natural history over time.
