This systematic review and meta-analysis evaluated the impact of mindfulness-based interventions (MBIs) on anxiety and sleep quality in 3,212 breast cancer patients across 24 randomized controlled trials. The analysis found that MBIs significantly reduced anxiety compared to control groups (SMD: -0.47, 95% CI: -0.62 to -0.32), but did not significantly improve sleep quality.
Key findings
- MBIs significantly reduced anxiety in breast cancer patients (SMD: -0.47, 95% CI: -0.62 to -0.32).
- No significant effect of MBIs on sleep quality was observed.
- Intervention duration accounted for 55.5% of the heterogeneity in anxiety outcomes.
- All studies had some concerns regarding risk of bias.
Why it matters
Anxiety is a common and distressing symptom in breast cancer patients, and effective nonpharmacological interventions like MBIs may enhance patient quality of life. Understanding their efficacy can guide supportive care strategies.
What to keep in mind
All studies had concerns regarding risk of bias, primarily due to self-reported outcomes and lack of blinding.
