Psoriasis cases rising

Psoraisis A Growing Global Burden
| Category: Latest feature

A major international study has examined how many people develop psoriasis worldwide and how this is likely to change over time. Using Global Burden of Disease data from 1990–2021, the researchers found that both the number of new psoriasis cases and the overall burden of the condition have increased and are projected to keep rising in the coming decades.​

The analysis shows that psoriasis affects people in every region, with particularly high burdens in high‑income countries and growing impact in many low‑ and middle‑income settings. From 1990 to 2021, global psoriasis cases rose substantially, and modelling suggests that this upward trend will continue beyond 2025, especially among adolescents and young adults.​

The study links these patterns to a mix of factors, including population growth, longer life expectancy, and changes in risk factors such as obesity and smoking, on top of genetic susceptibility. It also highlights persistent inequalities, with some regions experiencing faster increases and a greater impact on young people and women.​

For people living with psoriasis, this research underlines that the condition is a significant and growing public health issue, not just a cosmetic skin problem. The authors call for earlier diagnosis, better access to effective treatments, and targeted support for those at highest risk, particularly in countries where services are limited.​

For organisations like PAPAA, these findings reinforce the importance of raising awareness, improving understanding of psoriasis as a long‑term inflammatory disease, and advocating for joined‑up care that looks after skin, joints and overall health. As the number of people affected continues to increase, so does the need for high‑quality information, support and research to improve lives.​
