Psoriasis had a strong association with type 2 diabetes and obesity in a nationwide study of Danish twins, indicating a common genetic etiology between psoriasis and obesity, according to study results recently published in JAMA Dermatology.
Researchers in Denmark conducted a cross-sectional, population-based twin study that included 34,781 Danish twins born between 1931 and 1982, and aged 20 to 71 years. A questionnaire on psoriasis was validated with psoriasis diagnoses, and compared with diagnoses of type 2 diabetes and self-reported BMI. Data were collected in the spring of 2002 and were analyzed from Jan. 1 to Oct. 31, 2014.
