Measured physical activity in anorexia nervosa: features and treatment outcome.
2013
Objective: To assess the role of measured physical activity (PA) in anorexia nervosa treatment outcome, and to compare the PA of patients with anorexia nervosa with age-matched controls. Method: PA was assessed by means of Sense Wear Armband before and after a cognitive-behavioral inpatient treatment in 53 consecutive females with anorexia nervosa, and in 53 healthy age-matched controls. Results: At baseline, patients with anorexia nervosa exhibited a higher duration of moderate–vigorous PA (MVPA 3M etabolic Equivalent Tasks (METs)) than controls (t 5 2.91; p 5 .004). Dropouts had higher duration (sec) and expenditure (kcalday 21 ) of MVPA than completers. At the end of treatment, completers had a higher number of daily steps, MVPA duration, and expenditure than controls. However, PA was not correlated to eating disorder psychopathology either before or after treatment. Conclusions: PA is higher in patients with anorexia nervosa than age-matched controls both before and after treatment, and is associated with treatment dropout.
