Effect of exercise on fatigue and depression in breastcancer women undergoing chemotherapy: a systematic review and meta-analysis
摘要
This meta-analysis examined the effectiveness of exercise interventions in reducing fatigue and depression among women undergoing chemotherapy for breast cancer. The study followed PRISMA guidelines and analysed seven randomized controlled trials between 2016 and 2022. The results showed that exercise can substantially reduce fatigue levels (MD: -0.40, CI: -0.66, -0.14, P: 0.003), a common side effect of chemotherapy. Although depression did not significantly change (MD: -0.39, CI: -0.98, 0.20, P: 0.19), this study highlights the positive impact of exercise on mental health outcomes. The control group also experienced decreased quality of life (MD: 0.18, CI: 0.01–0.35, P: 0.03), emphasizing the importance of incorporating exercise interventions to improve overall well-being during breast cancer treatment. In addition to primary outcomes, the study revealed that exercise positively affected secondary aspects such as cognitive fatigue, social function, physical function, constipation, and dyspnoea.
