Effects of exercise programs on depressive symptoms, quality of life, and self-esteem in older people: A systematic review of randomized controlled trials

Abstract

Objective: This study attempted to show evidence of exercise programs as intervention to decrease depressive symptoms and to improve quality of life and self-esteem in older people. Design: Systematic review of randomized controlled trials. Data sources: Electronic databases of KoreaMed, Korea Scientific and Technological Intelligence Center, Korean Society of Nursing Science, Korean Academy of Psychiatric Mental Health Nursing, Ovid-Medline and Embase were searched up to May 25th, 2012 for relevant articles. Review: We searched studies of randomized controlled trials involving exercise programs administered to participants aged 65 years or over. Of 461 publications identified, 18 met the inclusion criteria for the meta-analysis. Quality assessment of the studies utilized Cochrane's Risk of Bias. Results: Exercise therapy in older people was effective, as evidenced by a decrease in depressive symptoms [standardized mean difference (SMD) -0.36; 95% confidence interval (CI) -0.64, -0.08], and improvements in quality of life (SMD 0.86; 95% CI 0.11, 1.62) and self-esteem (SMD 0.49; 95% Cl 0.09, 0.88). The changes were significant statistically, with no heterogeneity. Conclusions: Exercise programs in older people are effective in improving depressive symptoms, quality of life and self-esteem. Development and efficient use of tailored exercise programs for elderly people is a prudent strategy. (C) 2014 Elsevier Inc. All rights reserved.
