Physical (in)activity and its influence on disease-related features, physical capacity, and health-related quality of life in a cohort of chronic juvenile dermatomyositis patients

Physical capacity and health-related quality of life were reduced in JDM patients when compared with CTRL matched by physical activity levels, suggesting that the disease itself and/or glucocorticoid use may adversely affect overall health in JDM, despite an apparently well-controlled disease. Physical (in)activity correlated with important disease-related and physical capacity parameters, suggesting that sedentary lifestyle may be an important, but preventable, factor associated with poor overall health in JDM.
