Physical activity and self-rated health status among older adult cancer survivors: Does intensity of activity play a role?

Purpose/Objectives: To examine the association between routine physical activity and self-rated health status in older adults with cancer. Design: Cross-sectional. Setting: Community-dwelling older adult survivors who completed a screening tool and subsequent detailed interview from the 2004 wave of the National Long-Term Care Survey, a nationally representative study of Medicare beneficiaries aged 65 years or older. Sample: 251 older adult cancer survivors who regularly engaged in routine physical activity. Methods: Participants were asked about chronic health conditions, depression, activities of daily living, participation in physical activities, self-rated health status, and sociodemographic characteristics. A weighted ordered probit model was used to estimate variables that predict self-reported health status. Main Research Variables: Self-rated health status and participation in physical activity. Findings: Age and higher education level were found to be significant correlates of health status (p < 0.05) in the first model. Although education was not significant in subsequent models, age, functional disability, and depression all were identified as significant correlates of health status (p < 0.01). In the final model, in which moderate and vigorous activity participation were entered, older adult survivors who engaged in vigorous physical activity showed higher levels of health status than those who engaged in light physical activity (p < 0.05), but number of chronic health conditions was not significantly associated with health status. Conclusions: The association between vigorous activity and health status points to the primacy of physical activity within a post-cancer treatment health regimen. Implications for Nursing: Health programs and policies need to address physical activity to improve the overall well-being of older adult cancer survivors.
