A 2026 scoping review published in Anais Brasileiros de Dermatologia analyzed 15 studies across six continents to investigate psoriasis prevalence in 13 indigenous populations. The findings revealed that while some groups showed zero reported cases, others, such as the Inuit of Tasiilaq, Greenland, experienced higher rates than their national comparators.
Why it matters
Understanding the variation in psoriasis prevalence helps researchers investigate how genetic, environmental, and socioeconomic factors influence the condition. Addressing potential diagnostic access gaps remains essential for ensuring that indigenous populations receive accurate health assessments and care.
This scoping review evaluated 15 studies identified from 30 initial candidates to assess psoriasis frequency across 13 indigenous groups. While the study provides a broad perspective, it is limited by the variability of available diagnostic data across these diverse international populations.
The players
Anais Brasileiros de Dermatologia
A medical journal that publishes peer-reviewed research on skin diseases and dermatological advancements.
The details
The review searched major databases, including PubMed and the Cochrane Library, to identify studies that captured psoriasis prevalence within specific indigenous communities. Researchers suggest that observed differences in disease rates may stem from a combination of underlying genetic factors and external environmental or socioeconomic conditions. However, the study also highlights that a lack of clinical diagnostic resources in some regions may lead to underreporting, which could skew the true prevalence figures.
Timeline
The scoping review was published in 2026.
The National Psoriasis Foundation was accessed for context on October 1, 2026.
Health Landscape
This study aligns with the National Psoriasis Foundation's ongoing efforts to map global disease disparities and prevalence. It highlights the need to consider diverse genetic and environmental contexts when evaluating the global burden of chronic immune-mediated conditions.
Variations in skin conditions can be influenced by diverse factors, and it is important to discuss any persistent rashes or skin concerns with a physician for proper diagnosis. If you have concerns about your skin health or potential access to dermatology services, consult your primary care provider.
The takeaway
Psoriasis prevalence appears to vary significantly based on both geographic and population-specific factors. Always monitor changes in your skin health and discuss any concerns with a healthcare provider who can account for your unique background and environmental context.
