The Effects of Weight Loss on Psoriatic Arthritis

Psoriatic arthritis (PsA) is an inflammatory arthritis associated with psoriasis. Although the underlying cause of PSA is unclear, increased body weight is known to increase the disease symptoms. This study aims to determine the effects of dietary and Cognitive Exercise Therapy Approach (BETY-Bilişsel Egzersiz Terapi Yöntemi) interventions on symptoms. Accordingly, 45 overweight/obese subjects with PSA aged 20-65 years will divide into "diet", "diet+bety", and "control" groups. Dietary, laboratory and anthropometric records, Short Form Health Survey, DAPSA (Disease Activity in Psoriatic Arthritis), HAQ (Health Assesment Questionnaire) of all subjects will compare at the baseline and at the end of the study.
