Physical activity and quality of life of breast cancer survivors: a systematic review and meta-analysis
Tóm tắt
Introduction:Engaging in physical activity enhances the quality of life (QoL) for individuals diagnosed with breast cancer. However, there is a limitation in exiting studies with inconclusive data regarding the impact of various forms of physical activity on different dimensions of QoL. To address this gap, we undertook a systematic review and meta-analysis to evaluate the relationship between different physical activity groups and aspects of QoL in breast cancer survivors.
Methods:Our systematic search encompassed five databases, with data collected upto January 2023. The studies identified were categorized into four intervention groups based on the nature of physical activity (aerobic exercise, muscle-strengthening exercise, combination exercise, and other exercises), duration, frequency, and intensity of physical exercise. We employed random-effects models to estimate the standardized mean differences in health-related quality of life scores across these intervention categories .
Results:The 25 studies demonstrated positive associations between four groups of physical activity and QoL in breast cancer survivors. Aerobic exercise, muscle-strengthening exercise, combination exercise, and other types of exercise improved QoL by 0.45 (95% CI: 0.28 to 0.61), 0.49 (95% CI: 0.12 to 0.87), 0.73 (95% CI: 0.21 to 1.25), and 0.58 (95% CI: 0.16 to 0.99), respectively.
Conclusions:Engaging in various forms of physical activities can significantly improve the QoL for breast cancer survivors by alleviating specific symptoms and bolstering different aspects of overall wel-being. These findings em-phasizes the importance of providing tailored exercise programs to breast cancer patients as part of their treatment regiment to improve their QoL both during and after treatment.
