Although the underlying cause of PSA is unclear, increased body weight is known to increase the disease symptoms. The present study aims to determine the effects of dietary and Cognitive Exercise Therapy Approach interventions on symptoms.~Fourt-five overweight/obese subjects with PSA aged 20-65 years will divide into diet (n=15), diet+bety (n=15), and control (n=15) groups.~Individually diet programs will be applied according to the metabolic, biochemical, and physical activity status of the subjects prepared by a registered dietitian.~BETY exercise training will be given by a registered physiotherapist.~The subjects will be followed for 12 weeks.~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 study completion.
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.
