Study Links Psoriasis to Type 2 Diabetes
People with psoriasis are at increased risk for developing type 2 diabetes, suggest researchers at the Perelman School of Medicine at the University of Pennsylvania in Philadelphia. Their research results were published this month in the Journal of the American Academy of Dermatology.
The study involved 8,124 adults with psoriasis and 76,599 adults without psoriasis from a United Kingdom database. Researchers measured the percentage of the body covered by psoriasis (called body surface area, or BSA) and evaluated diabetes risk over a four-year period.
They discovered that psoriasis patients with a BSA of 2 percent or less had a 21 percent higher-than-average risk for type 2 diabetes, and those with a BSA greater than 10 percent had a 64 percent higher risk. According to the researchers, this risk occurs independent of typical diabetes risk factors like body weight, and may be related to the type of inflammation that occurs in psoriasis, which can promote insulin resistance.
