HealthDay News — Patients with severe psoriasis are less likely to engage in physical activity, results of a study published in the Journal of Dermatology indicate.

“Despite evidence that physical activity can reduce the cardiometabolic risk of patients with psoriasis, these patients may engage in less physical activity than those without psoriasis,” noted Young Kyung Do, MD, MPH, PhD, of the Seoul National University College of Medicine in South Korea, and colleagues.

To examine the correlation between the extent of psoriatic lesions and the likelihood of participating in leisure-time moderate to vigorous physical activity, the investigators collected data from 6,549 respondents, aged 20 to 59 years, from the 2003 to 2006 National Health and Nutrition Examination Survey dermatology questionnaires.

Individuals with psoriasis were less likely to have engaged in leisure-time physical activity in the past 30 days compared to those without psoriasis; the correlation was not statistically significant. Among those who participated in physical activity, patients currently having few to extensive cutaneous lesions (but not those currently having little or no psoriatic patches) logged approximately 30% fewer metabolic equivalent task-minutes of leisure-time MVPA compared with individuals never diagnosed with psoriasis.

“Clinicians should encourage patients with psoriasis, especially those with more severe disease, to be more physically active; they should help identify and address possible psychological and physical barriers to their patients’ physical activity,” stressed the scientists.
