The models compares the least square mean values in patients physically inactive according to WHO (patients who did not met WHO recommendations) versus patients who met WHO recommendations. The least square means were estimated using Linear Mixed Models. Model I: an adjusted. Model II: adjusted for age and disease duration. Model III: adjusted for age, disease duration, education level and TAS score. Abbreviations: SE, standard error. MeS+, patients with MeS. MeS-, patients without MeS. GC, glucocorticoids. hd GC, high doses of glucocorticoids (daily dose ≥ 7.5 mg of prednisone or equivalents). MCS, mental component summary. PCS, physical component summary.
