Exercise Addiction and Major Depressive Disorder – Clinical Diagnoses and Longitudinal Course

BACKGROUND: People at risk of exercise addiction report increased symptoms of psychopathology. The aim of this study was to clinically assess the lifetime prevalence of depressive disorders in individuals at risk of exercise addiction and to determine whether depressive symptoms tend to precede or follow excessive exercising. METHODS: Based on the Exercise Dependence Scale-21, a total of 31 individuals categorized at risk of exercise addiction underwent the Structured Clinical Interview for DSM-5 to assess major depressive disorder (MDD). FINDINGS: The results showed 16 of the 31 participants suffered from MDD. The onset of MMD occurred in 10 participants after excessive exercising and in 5 before excessive exercising. In one participant, the symptom onset was unclear. CONCLUSION: MDD is far more prevalent in patients with exercise addiction compared to the general population and develops more often after the beginning of exercise addiction. Caution in the use of exercise to treat depression may be warranted.
