HIGHLIGHTS
- Regular PA provides important health benefits for cancer survivors.
- PA among cancer survivors is lower than those without a cancer history.
- Rates for meeting PA guidelines for aerobic activity are similar between groups.
- PA was higher for colon and other cancers but not breast or prostate cancers.
- Promoting PA is an opportunity to improve health outcomes among survivors.
ABSTRACT
Introduction
: The decline in U.S. cancer deaths from early detection and treatment advancements has markedly increased the number of cancer survivors. Regular physical activity (PA) after cancer diagnosis has been associated with numerous health benefits, including reduction in cancer-related fatigue, quality of life, physical fitness and functioning, and improved mental health. This study aims to explore PA trends, differences, and meeting PA guidelines in adults with vs. without a cancer history using national data.
Methods
The study used Behavioral Risk Factor and Surveillance data from 2018-2024 to estimate survey-weighted annual PA prevalences among adults with and without a cancer history. Trends were assessed using log-linear regression. Aerobic guideline adherence and cancer-type-specific estimates were also examined for prostate, breast, colon, and other cancers.
Results
Among over two million adults, PA prevalence increased significantly among adults with a cancer history (67.1% to 71.6%; annual percentage change (APC) = 1.05%; 95% CI, 0.6% – 1.5%) but not those without a cancer history (76.3% to 78.3%; APC = 0.47%; 95% CI, -0.19% – 1.14%). Cancer history was associated with a 3.8 percentage-point lower adjusted prevalence of PA. Aerobic PA guideline adherence was similar by cancer history.
Conclusions
: Cancer survivors had a lower PA prevalence across the study time-period than those with no cancer history. Similar rates of meeting the PA guidelines for aerobic activity were observed. The higher prevalence of no PA among cancer survivors presents an opportunity to promote PA through targeted interventions for healthcare provider counseling and cancer-specific training by exercise specialists.
