MDD is a leading cause of disability and plays an important role in the global burden of disease. Major depressive disorder (MDD) is a common medical condition that severely lowers the quality of life and limits psychosocial functioning. These results help to understand the manifestations of MDD and provide evidence and direction for the advancement of intervention and prevention.

Inactivity may increase the risk of MDD, which was mediated or masked by brain imaging phenotypes. In conclusions, we found that social/physical activities reduced the risk of MDD, while MDD in turn hindered social/physical activities. Furthermore, we discovered that MDD increased the risk of leisure/social inactivity (OR = 1.03 P = 9.89 × 10 −4) or physical inactivity (OR = 1.01 P = 7.96 × 10 −4). We also observed that leisure/social inactivity (odds ratio = 1.64 P = 5.14 × 10 −5) or physical inactivity (OR = 3.67 P = 1.99 × 10 −5) caused an increased risk of MDD, which were partially mediated by BMI or BFP and masked by the weighted-mean orientation dispersion index of left acoustic radiation or volume of right caudate. We identified bidirectional causal relationships between sport clubs or gyms, strenuous sports, heavy do-it-youself, other exercises and MDD. Information regarding body mass index (BMI), body fat percentage (BFP), IDPs for 454,633 461,460 8,428 participants, respectively. The dataset on MDD, social activities, and physical activities included 500,199 461,369 460,376 individuals, respectively. Here, we performed a two-sample Mendelian Randomization analysis using genetic variants associated with social/physical activities and MDD, and assessed the mediating effect of obesity-related measures and brain imaging phenotypes. However, the bidirectional relationship between them remains to be clarified further, especially between inactivity and MDD. A growing body of research suggests that social or physical activity can affect the risk of Major depressive disorder (MDD).
