The SAFE (i.e., Sleep and Activity For Eating disorders) study aims to investigate the characteristics of sleep, daytime activity, and circadian rhythms in a sample of patients with eating disorders-specifically anorexia nervosa, bulimia nervosa, and binge-eating disorder-as well as the relationship between these variables and physiological parameters (i.e., body mass index, hormone levels, blood chemistry parameters) and psychological parameters (i.e., levels of depression and anxiety, body image, eating-disorder symptoms).
