The extent to which the occurrence of psoriasis varies over time, as well as by gender and with age, has not been systematically explored. Therefore, we – a group of researchers based in Manchester, UK – aimed to perform a systematic review of published studies on variations in psoriasis incidence (the number of new individuals affected by psoriasis during a particular period of time) and prevalence (all individuals affected with the disease at a particular time) over time, as well as by gender and with age. We systematically searched 11 large electronic databases and identified 90 studies from 22 countries. We observed two peaks in age bands in psoriasis onset, with the first and second peak at around 30–39 and 60–69 years of age, respectively. Evidence suggested psoriasis presents slightly earlier in women than men. There was no agreement on specific differences between genders in psoriasis incidence and prevalence. However, a slight male predominance was reported in several studies. The prevalence of psoriasis has been consistently reported to be increasing over time, while the incidence of psoriasis has been reported to be stable or slightly decreasing over time. Our conclusion is that studies on changes over time in the occurrence of psoriasis have contributed to a greater appreciation of the increasing burden of the disease. However, further research is required to determine the reason driving the increase in psoriasis prevalence over time. Linked Article: Iskandar et al. Br J Dermatol 2021; 184:243–258.
