Fig. 1

Circadian activity patterns over 24-h according to body mass index (BMI) and age. Different colors represent different age groups in order to illustrate the differences in activity patterns, but this categorization was not applied in the analysis (i.e. all parameters are considered as continuous variables). Top panel: healthy controls, Lower panel: participants with a history of affective disorders. The black arrows on top of the curves show the reduction or increase of the activity values by growth of BMI values
