| 摘要: |
| 久坐行为被认为是影响机体身心健康的先兆因素，久坐行为可引起抑郁症的发生发展。在久坐行为与抑郁症的相关性分析中，不同人群均存在久坐行为诱发抑郁的现象，且成人的久坐时长增加，罹患抑郁症的风险更高。在生物学机制中，久坐行为可诱导大脑功能障碍、神经营养因子紊乱以及肠道菌群紊乱，诱发抑郁症。体育活动的增加导致久坐行为的减少，将会对抑郁起到明显的改善作用，其机制为：体育活动可缓解精神压力，提高神经功能和肠道菌群功能，最终缓解抑郁症的发展。 |

| Abstract: |
| Sedentary behavior is considered to be a precursor factor affecting the physical and mental health of the body. Sedentary behavior can cause the occurrence and development of depression. In the correlation analysis between sedentary behavior and depression, the phenomenon of depression induced by sedentary behavior exists in different populations, and the risk of depression is higher in adults with increased sedentary time. In the biological mechanism, sedentary behavior can induce brain dysfunction, neurotrophic factor disorder and intestinal flora disorder, and induce depression. The increase in physical activity leads to a decrease in sedentary behavior, which will significantly improve depression. The mechanism is that physical activity can relieve mental stress, improve neurological function and intestinal flora function, and ultimately alleviate the development of depression. |
