1 The World Health Organization projects that depression could become the single highest contributor to the global disease burden by 2030. Moreover, it has a significant impact on families and health care organizations. It reduces quality of life and well-being, and increases the risk of disability, suicide, and mortality. Keywords: physical activity, depression, protective factor, older adults, Chinese veteranĭepression is a common mental health problem in older adults, not only affecting mood but also leading to functional decline in those affected. This information could be used to devise further interventions to prevent or ameliorate symptoms of depression. It was also indicated that the antidepressant effect of physical activity probably extended to the oldest-old, and the light-intensity physical activity was probably available for the same protective effect. In a univariate general linear model, there was a significant difference in Center for Epidemiological Studies Depression Scale score between subjects participating in active physical activity and those who did not ( F=59.07, P<0.0001).Ĭonclusion: This study found an inverse relationship between physical activity and symptoms of depression in older Chinese veterans in the community. Multivariate logistic regression with adjustment and controlling for confounders, physical activity was still inversely associated with depressive symptoms and was the only independent protective factor (odds ratio 0.57, 95% confidence interval 0.44–0.72, P<0.0001) among the associated factors in this study. In unadjusted analyses, physical activity was associated with a significantly decreased likelihood of depressive symptoms (5.43% versus 18.83%, P<0.0001). In total, 81.84% of the study participants engaged in physical activity that was predominantly light in intensity. Results: The median age was 82.29 (interquartile range 80.25–84.60) years. Relationships between study variables and symptoms of depression were estimated using unadjusted and adjusted analyses. Information about covariates was obtained by questionnaire-based interview. Physical activity was self-reported using a one-year physical activity questionnaire.
Depressive symptoms were identified using the Center for Epidemiological Studies Depression Scale. Methods: A cross-sectional study was conducted in a representative sample of 9,676 community-dwelling older Chinese veterans. We performed a nationwide epidemiological survey to determine the relationship between physical activity and depressive symptoms in older Chinese veterans in the community, with adjustment for potential confounders. However, large-scale epidemiological research on this issue is lacking in older Chinese adults.
