Changes in physical activity and associations with quality of life among a global sample of cancer survivors during the COVID-19 pandemic

Purpose Meeting physical activity (PA) guidelines (i.e., >= 150 min/week of aerobic PA and/or 2 days/week of resistance training) is beneficial for maintaining cancer survivors' well-being. The impact of the COVID-19 pandemic on PA participation in cancer survivors and its association on quality of life (QoL) remains unknown. The purpose of this study was to compare PA levels prior to and during the COVID-19 pandemic, and examine the association between changes in PA and QoL in cancer survivors. Methods A global sample of cancer survivors participated in a cross-sectional, online survey. Participants self-reported their PA participation before and during the pandemic using the Godin Leisure Time Exercise Questionnaire and QoL with the Functional Assessment of Cancer Therapy (FACT) scales. Paired t-tests compared PA before and during the pandemic. Analysis of covariance examined differences in QoL between PA categories: non-exercisers, inactive adopters, complete and partial relapsers, single and combined guideline maintainers. Results PA participation of cancer survivors (N=488) significantly decreased during the pandemic (p's < .001). Cancer survivors were classified as non-exercisers (37.7%), inactive adopters (6.6%), complete (13.1%) and partial (6.1%) relapsers, and single (23.8%) or combined (12.7%) guideline maintainers. Partial relapsers had significantly lower QoL and fatigue than inactive adopters, and combined guideline maintainers (p's < .05) that were clinically meaningful. Conclusion PA decreased during the pandemic which has negative implications for QoL and fatigue in cancer survivors. Implications for Cancer Survivors PA is critical for maintaining QoL during the pandemic; therefore, behavioral strategies are needed to help cancer survivors adopt and maintain PA.
