â¢Additional exercise training reduces epicardial and subcutaneous adipose tissue in patients with major depressive disorder.â¢In patients without additional exercise training, visceral fat compartments increased.â¢Given the higher prevalence of cardio-metabolic disorders in major depression, additional exercise may be recommended for considering in the treatment plan of depression.
ObjectiveMajor depressive disorder (MDD) is associated with increased amounts of intra-abdominal and epicardial adipose tissue, risk factors for the development of cardio-metabolic disorders. Exercise has been shown to reduce intra-abdominal fat in different conditions such as obesity and diabetes mellitus, thereby reducing cardio-metabolic risks. Therefore we examined the effects of exercise on adipose tissue compartments in patients with MDD.MethodsOf thirty depressed patients included, twenty received supervised exercise training, and ten received no specific training. Volumes of subcutaneous, intra-abdominal and epicardial adipose tissue were measured using magnetic resonance imaging, and factors constituting the metabolic syndrome were determined.ResultsSignificant effects of the training condition were observed on the amount of epicardial adipose tissue (P=0.017), subcutaneous adipose tissue (P=0.023), weight (P=0.047), body-mass index (P=0.04), high density lipoproteins (P=0.021) and the number of metabolic syndrome factors (P=0.018). The amount of intra-abdominal adipose tissue decreased slightly, although not significantly, in the exercise group.ConclusionExercise training reduces the amount of visceral, in particular epicardial adipose tissue, in patients with MDD, and ameliorates factors constituting the metabolic syndrome. Given the high prevalence of cardio-metabolic disorders in major depression, exercise training may be recommended as an additional treatment component.
