The relationship between physical activity and depression among community-dwelling adults in Wuhan, China

Abstract

BackgroundWhile the association between physical activity (PA) and depression has been established, there is limited research on the effect of PA on the risk of depression among Chinese individuals. Thus, this study aimed to investigate the relationship between PA and depression among Chinese individuals.MethodsWe used a stratified random sampling approach to recruit participants from five urban districts in Wuhan, China. A total of 5,583 permanent residents aged 18 years or older completed questionnaires, which included the International Physical Activity Questionnaire Short Form (IPAQ-SF) to measure PA, and the 9-item Patient Health Questionnaire (PHQ-9) to evaluate depressive symptoms. To control for potential confounders, multiple logistic regression was employed to assess the association of PA with depression.ResultsThe depression group had significantly lower weekly PA levels, measured in metabolic equivalent of task-minutes per week (MET-min/w), compared to the non-depression group [1,770 (693–4,200) MET-min/w vs. 2,772 (1,324–4,893) MET-min/w, p < 0.001]. In the fully adjusted model, the moderate and high PA level groups had lower odds ratios (ORs) for depressive symptoms compared to the low PA level group [OR (95% confidence interval (CI)) = 0.670 (0.523–0.858), 0.618 (0.484–0.790), respectively]. Among males, moderate and high levels of PA were associated with lower risk of depression compared to low PA levels [OR (95% CI) = 0.417 (0.268–0.649), 0.381 (0.244–0.593), respectively]. However, this association was not observed in females [OR (95% CI) = 0.827 (0.610–1.121), 0.782 (0.579–1.056), respectively]. The study found a significant interaction between PA levels and gender in relation to depression (P for interaction = 0.019).ConclusionThe findings suggest a negative association between PA and risk of depressive symptoms, indicating that moderate to high levels of PA may serve as a protective factor against depressive symptoms.

Association of habitual physical activity with depression and anxiety: a multicentre cross-sectional study

“… 26 Recently, a cross-sectional study from National Health and Nutrition Examination Survey (NHANES) also revealed the protective effect of physical activity against depression. 34 Additionally, several epidemiological studies among the Chinese also revealed a similar beneficial role of physical activity in decreasing depression risk, 35–38 while sedentary behaviour was positively associated with depression in a dose-response manner. 39 The possible mechanism might be explained by the reaction of the endocannabinoid system to acute neuroendocrine stimulation and inflammation and changes in neural architecture.…”

Association Between Physical Activity and Depression in Middle Aged Premenopausal and Postmenopausal Women in Malaysia

“…There has been a great deal of research conducted on the link between physical activity and depression; however, there has not been a great deal of research conducted on the link between physical activity and depression specifically among middle-aged premenopausal and postmenopausal women in Malaysia [8]. A comprehensive understanding of the factors that may play a role in the development of depression in a population is necessary for the creation of individualized treatments and the advancement of mental health.…”
