Abstract
Objective The relative efficacy of exercise regimens for improving sleep quality in adult breast cancer survivors remains unknown. This network meta-analysis aimed to compare the efficacy of various exercise regimens for improving sleep quality in adult breast cancer survivors.
Methods This study searched four electronic databases for relevant literature from inception to 18 July 2023. Randomised controlled trials reporting the effects of exercise on sleep quality in adults with breast cancer were included. A random-effects network meta-analysis based on the frequentist framework was performed.
Results In total, 35 trials including 3374 breast cancer survivors were included. Compared with usual care, endurance training combined with resistance training significantly improved sleep quality (standardised mean differences (SMDs) = −0.97; 95% CI = −1.50 to −0.43; certainty of evidence=moderate) (p<0.05). Endurance training combined with resistance training (SMDs: −1.42; 95% CIs: −2.31 to −0.53; moderate) achieved superior sleep quality results compared with stretching exercises (p<0.05). The surface under the cumulative ranking curve analysis indicated that endurance training combined with resistance training was ranked as the top effective treatment among other exercise regimens for improving sleep quality in breast cancer survivors (71%).
Conclusions Endurance training combined with resistance training is effective in improving sleep quality in adult breast cancer survivors. Our results provide evidence that exercise can improve sleep quality in adult breast cancer survivors.
