Abstract Introduction:<\b>
Physically active cancer survivors have a reduced risk of cancer recurrence and mortality. There is a need to develop and evaluate effective physical activity interventions that employ distance-based, broad-reaching (i.e., non face-to-face) approaches. The primary objective of this study was to conduct a meta-analysis of broad-reach physical activity behavior change interventions (from 2013 to 2017) for cancer survivors. Methods:<\b>
PubMed and Embase databases were searched from May 2013 up to October 2017. Studies met the following criteria if: 1) they included post diagnosis adult cancer survivors, 2) the intervention was distance-based with no more than one face-to-face visit or contact, and 3) physical activity was measured pre and post intervention. Review Manager 5 (RevMan 5) software was used to conduct a meta-analysis on all RCTs that presented self-reported moderate-to-vigorous intensity physical activity (MVPA) pre and post intervention means and standard deviations. Results:<\b>
Data from 13 RCTs (16 comparisons) were included. Overall, studies were found to be of moderate quality. Excluded studies did not provide MVPA data. The analysis was based on 3,350 patients (1,675 for both intervention and control). These interventions resulted in a small overall effect (standardized mean difference) of 0.19 (95% CI 0.07, 0.30), which was significant (Z=3.26, p=0.001). There was significant (p=0.002) and moderate heterogeneity (I2=58%) across the included trials.Conclusions: As changes in physical activity are generally small, relying on the present content of broad-reach programs aiming to facilitate physical activity in cancer survivors may not be prudent.
