Physical Activity
Physical activity has numerous benefits including improving physical function, sleep, mood, and overall quality of life. It can also reduce the risks of cancer and cardiovascular disease. However, most adults in the U.S. do not engage in regular physical activity; for those with serious illness getting enough physical activity can be especially challenging. However, for patients with serious illness, physical activity may be important in helping them tolerate treatments and maintain their physical functioning and quality of life.
We are particularly interested in ways to help individuals not just increase their activity but maintain these increases over time. Involving a significant other such as a spouse may provide the necessary social support to help people meet their physical activity goals and continue to keep up their good habits. It can also have a “2 for 1” effect, helping both partners increase their physical activity.
Couple-based Physical Activity Intervention for Patients Undergoing Hematopoietic Cell Transplantation
Dr. Porter is currently collaborating with Dr. Shelby Langer at Arizona State University on a study testing a couple-based physical activity intervention for patients undergoing stem cell transplantation.
Couple-based Physical Activity Intervention for Cancer Survivors
We developed a novel couple-based physical activity intervention delivered by videoconference for survivors of breast and prostate cancer and their spouses/partners. The intervention combined behavioral change techniques with training in skills for communication and support. Results of a small pilot study indicated that cancer survivors found the intervention acceptable and that it led to improvements in physical activity, partner support, and physical well-being.
This study was funded by the Duke Cancer Institute.
We are currently seeking funding to conduct a larger study focused on men with advanced prostate cancer and their partners.
Enhancing Physical Functioning in Patients with Advanced Lung Cancer
We recently completed a study among older adults with advanced lung cancer to enhance their physical functioning. The intervention taught patients to set goals around physical health that are promotion-focused (making good things happen) and prevention-focused (keeping bad things from happening). Results indicated that the intervention improved the patient's overall functioning and quality of life.
This study was funded by the Duke Roybal Center.
