Abstract
Purpose: To examine the prevalence and correlates of physical activity in adult survivors of aggressive non-Hodgkin's Lymphoma (NHL) and to explore the association between physical activity level and health-related quality of life (HRQOL). Patients and Methods: Physical activity and HRQOL data from 319 survivors of NHL (mean age, 59.8 years, standard deviation, ±14.8) who were diagnosed in Los Angeles County approximately 2 to 5 years before the study was analyzed. Results: One quarter of survivors of NHL met public health guidelines of 150 minutes or more of moderate to vigorous exercise per week. More than half (53%) reported some activity but less than 150 minutes per week, whereas 20% reported no physical activity. Females, those with lower perceived health competence, and individuals with more comorbid limitations were at increased risk for inactivity. Individuals who met public health guidelines reported better HRQOL than those who were sedentary. Interestingly, our findings suggest a significant positive association between HRQOL and those who get at least some exercise. Conclusion: The effort to promote physical activity among cancer survivors, who are at risk for poor quality of life as a result of treatment, is of great importance to the health of this growing population. As NHL, similar to other cancers, becomes a disease that people live with as opposed to one that people die as a result of, oncologists and primary care physicians will be increasingly challenged to provide evidence-based guidance for the long-term management of the patient's health. Consideration should be given to how clinicians frame exercise-promoting messages to cancer survivors, especially to those who are sedentary.
