Do Patients with Mild to Moderate Psoriasis Really Have a Sedentary Lifestyle?

The aim of this study was to compare aerobic exercise capacity, daily physical activity, pulmonary functions, resting metabolic rate, and body composition parameters in patients with psoriasis and healthy controls. A total of 60 participants (30 [15 men, 15 women] patients with psoriasis, and 30 [15 men, 15 women] healthy controls) ranging in age from 22-57 were included in the study. Maximal aerobic capacity was determined by Astrand exercise protocol. Daily physical activity was measured with an accelerometer. Resting metabolic rate was determined with an indirect calorimeter. Pulmonary function tests were performed with a portable spirometer. Body composition was established with a bioelectric impedance analysis system. Skinfold thicknesses and body circumference measurements were carried out. Short Form 36 quality of life questionnaire was applied to all participants. In both genders, daily physical activity parameters were found to be higher in the psoriasis group compared to the control. Maximal aerobic capacity, resting metabolic rate, pulmonary function tests, body fatness, body fat distributions, and quality of life were not statistically different between patients with psoriasis and controls in males and females. We suggest that patients with psoriasis who do not have psoriatic arthritis or severe psoriasis are well in performing daily physical activities. In addition, we suggest that this lifestyle helped to prevent impairments of body fatness, body fat distributions, resting metabolic rate, pulmonary functions, and quality of life in patients with mild to moderate psoriasis.
