Resources for Public Health Professionals

To many, psoriasis is viewed as exclusively a disease of the skin. This misconception obscures the underlying systemic processes occurring and the larger implications for overall health. Ultimately, this can create barriers to the optimization of patient outcomes, particularly for underserved communities.

What is psoriasis?

Psoriasis is an immune-mediated systemic inflammatory disease affecting an estimated 7.5 million adults in the United States. [1] Visibly, psoriasis displays as raised plaques and scales on the skin and can look differently on depending on a person’s skin tone. [2] Psoriasis can appear on any part of the body and affect anyone at any age. Common locations for psoriasis lesions include the genitals, scalp, face, and hands, feet, and nails.

Though plaque psoriasis is the most common form of the disease, there are five different types of psoriasis:

Isn’t psoriasis just a skin disease?

The systemic inflammatory processes that cause psoriasis mean that psoriasis is more than a skin disease. The inflammation that causes psoriasis contributes to the development of psoriatic arthritis, and higher rates of co-occurring diseases such as diabetes, cardiovascular disease, obesity, and depression among many others. [3-5] It is estimated that 30% of individuals with psoriasis will develop psoriatic arthritis.[6] Currently, there is no test to diagnose psoriatic arthritis. However, there are validated screening tools for psoriatic arthritis that can help patients get treatment.

Why should public health professionals be concerned about psoriasis?

Research suggests psoriasis contributes to poorer outcomes for individuals who have co-occurring disease (e.g., cardiovascular diseases, diabetes) and higher mortality rates. [7, 8] Further, having psoriasis – especially moderate to severe psoriasis – can be a barrier to common public health interventions (e.g., engaging in physical activity). [9]
