When helping helps: exploring health benefits of cancer survivors participating in for-cause physical activity events.

Background: Over 15.5 million Americans live with cancer and 5-year survival rates have risen to 69%. Evidence supports important health benefits of regular physical activity for cancer survivors, including increased strength and quality of life, and reduced fatigue, recurrence, and mortality. However, physical activity participation among cancer survivors remains low. Cancer organizations provide various resources and support for cancer survivors, including emotional, instrumental, informational, and appraisal support. Many cancer organizations, like the LIVESTRONG Foundation, support the cancer community by sponsoring and hosting for-cause physical activity events, providing opportunities for anyone (including cancer survivors) to "help"/support those living with cancer. The concept of helping others has been positively related with wellbeing, physical activity, and multiple health behaviors for those helping. However, the role of helping others has not been examined in the context of being physically active to help others or its relationship with overall physical activity and quality of life among those helping. Therefore, we developed a path model to examine relationships between cancer survivors' (1) desire to help others with cancer, (2) physically active LIVESTRONG participation to help others, (3) regular physical activity engagement, and (4) quality of life.

Methods: In 2010, 3257 cancer survivors responded to an online survey sent to all people involved with the LIVESTRONG organization at any level. The hypothesized path model was tested using path analysis (Mplus 8).

Results: After list-wise deletion of missing responses, our final sample size was 3122 (61.8% female, mean age: 48.2 years [SD = 12.7]). Results indicated that the model yielded perfect fit indexes. Controlling for age, sex, income, and survivorship length, desire to help was positively related with physically active LIVESTRONG participation (β = .11, p < .001), which was positively related with regular physical activity (β = .30, p < .001), and regular physical activity was positively related with quality of life (β = .194, p < .001).

Conclusions: Results suggest that cancer survivors can benefit from participating in for-cause physical activity events, including more regular physical activity. Researchers need to further investigate the role of helping others when examining health behaviors and outcomes, and cancer organizations should continue encouraging cancer survivors to help others by participating in physical activity events.
