Psoriasis Statistics

Psoriasis and psoriatic arthritis are becoming more common than most people realize.

Two to three percent of the world’s population is affected by psoriasis. 125 million people suffer from psoriasis all around the world.

In America there are between 5.8 and 7.5 million individuals with psoriasis according to the National Institutes of Health (NIH).

As if psoriasis wasn’t bad enough, as much as 30% of people who already have psoriasis may also contract arthritis.

Chronic Problem

Psoriasis is not just a cosmetic problem, it is a skin disease that is chronic (lifelong). It can be serious, even life-threatening if not treated properly.

Psoriasis is an everyday part of life for those who suffer from it. Individuals who have psoriasis that covers their entire body may experience a greater negative impact that can really affect their life.

In studies 40% of the respondents in the study say that they are satisfied with treatments when the treatments involved acitretin, cyclosporine, methotrexate or PUVA.

Those with psoriasis who are members of psoriasis organizations that support members such as the National Psoriasis Foundation report that they are less bothered with their disease and trust their treatment progress more than those who do not have this support.

The most common onset of psoriasis is between the ages of 15 and 25 but it can occur at any age.
The special type of psoriasis known as psoriatic arthritis typically has onset between the ages of 30 and 50 but it too can develop at any time in life.

Levels of Psoriasis

Psoriasis has three levels of severity: mild, moderate and severe. Mild is defined as affecting less than 3% of the body, moderate is when it affects 3% to 10% of the body, and the severe psoriasis is when it affects more than 10% of the body. The percentage of the affected body is not the only determination for severity. Another determination is how much the disease affects the quality of the individual’s life. No matter how small the amounts of psoriasis on the body it will still have an impact on the quality of life. Most individuals have the mild form of psoriasis. One-fourth of those with psoriasis have the moderate form.

The cost of psoriasis can be extensive. A study conducted in 1993 estimated that the cost of treating psoriasis was between $2 and $3 billion.

There seems to be a genetic connection with the disease psoriasis because it is reported that 1 out of 3 individuals who have psoriasis also have a blood relative with psoriasis.

Statistically if a child has one parent with psoriasis that child has a 10% chance of having psoriasis. Should both parents have psoriasis, than the child has a 50% chance of developing the disease.

Statistics are important because they give vital information about the advancement of the disease, and how it affects the individuals who have it and to the extent that it impacts the quality of their lives. The National Psoriasis Foundation conducts survey panels biannually in the effort to continue to gather information that can aid the understanding of this disease. Information can give answers to important questions and can bring about comfort to those who suffer.
