Teenagers who have psoriasis, according to a recent study conducted by Razieh Soltani-Arabshahi the M.D. of the University Of Utah School Of Medicine, Salt Lake City, have a greater chance of developing psoriatic arthritis if they are obese. The major factors of such disease are most of the times young age, being female and a larger body surface area. There are several other factors of this disorder as well.

It has also been found that obese people who have had psoriatic arthritis before are more likely to get the disorder than only overweight people or people with a normal BMI who have had psoriatic arthritis before.

To identify which group of patients with the psoriasis disorder is more susceptible to developing psoriatic arthritis, the risk factors were taken into consideration, using advanced epidemiologic techniques.  

It is these risk factors and their recognition which ultimately helps in diagnosing the condition of the disorder, and improves its remedy by modifying its risk-factor.

This study by Razieh Soltani-Arabshahi was published in the Archives of Dermatology in its 19th July issue.
