title: Relationship between the intensity of physical activity and depressive symptoms among Korean adults: analysis of Korea Health Panel data.
abstract: [Purpose] The aim of this study was to examine the relationship between the intensity of physical activity and symptoms of depression. [Subjects and Methods] We analyzed the influence of different intensities of physical activity on depressive symptoms using the data of 12,350 adults over the age of 20 years who had completed the 2011 Korea Health Panel. After controlling for confounding variables, a multivariable logistic regression analysis was conducted to identify the association between the intensity of physical activity and depressive symptoms. [Results] The results showed that vigorous physical activity had a significant effect on depressive symptoms. The incidence of depressive symptoms was 1.487 (95% CI 1.137, 1.943) OR higher among people who did not participate in regular activity than it was among those who took part in regular intense physical activity. [Conclusion] It appears that physical activity affects depressive symptoms, a result which is in agreement with previous studies. However, we also showed a difference in influence according to activity intensity. Thus, the intensity of physical activity should be considered when developing physical activity programs for improving depressive symptoms.
