This randomized controlled trial analyzed the relationship between physical activity (PA) and quality of life (QoL) in 341 breast cancer survivors post-treatment. The study found that greater self-reported moderate to vigorous PA (MVPA) was associated with better QoL, particularly in survivors over 24 months post-diagnosis and those receiving hormone therapy. Notably, the EuroQOL-5D-5L QoL index showed significant correlations with MVPA levels.
Key findings
- The EuroQOL-5D-5L QoL index showed significant associations with self-reported MVPA.
- Survivors > 24 months post-diagnosis had stronger associations between MVPA and QoL (β = 0.0004, P = .003).
- Hormone therapy recipients exhibited stronger associations between MVPA and PROMIS-physical health QoL (β = 0.0121, P = .028).
Why it matters
Understanding the impact of physical activity on quality of life in breast cancer survivors is essential for developing targeted interventions. This study highlights the importance of considering treatment history and time since diagnosis when designing supportive programs.
