People who are obese at age 18 may be at an increased risk for psoriatic arthritis later in life, according to a report in the July issue of the Archives of Dermatology. In a single-center study of 943 psoriasis patients, those who reported being obese at age 18 were three times more likely to develop psoriatic arthritis (PsA), compared with patients who reported having a normal body mass index at age 18, reported Dr. Razieh Soltani-Arabshahi and associates of the University of Utah School of Medicine, Salt Lake City.
