Physical Activity Among Utah Cancer Survivors: Analysis From a Population-Based Statewide Survey

Background: Regular physical activity improves cancer survivors' health-related quality of life and physical function. We estimated the proportion of Utah cancer survivors meeting U.S. Department of Health and Human Services guidelines for weekly physical activity (aerobic plus strength exercise) and identify sociodemographic, cancer, and health-related factors associated with meeting guidelines. Methods: Survivors randomly sampled from Utah Cancer Registry records were surveyed from 2018 to 2022 to ascertain physical activity. We calculated the percent of survivors meeting guidelines and conducted logistic regression to assess predictors of meeting guidelines. Analyses were weighted to account for complex survey sample design and nonresponse and age adjusted. Results: Among Utah cancer survivors, 20.7% (95% CI, 18.5%-23.2%) met guidelines for both aerobic activity and strength exercise. 22.4% reported no aerobic exercise in a typical week, and 59.4% reported no strength exercise. Survivors 75 or older were less likely to meet physical activity guidelines than those under 55 (adjusted odds ratio: 0.40; 95% CI, 0.25-0.65). Survivors with a bachelor's degree or higher were more likely to meet physical activity guidelines than those without a college degree. Individuals with poorer overall health were less likely to report sufficient physical activity. Individuals treated with both chemotherapy and radiation had decreased odds of meeting guidelines compared to no treatment (adjusted odds ratio: 0.54; 95% CI, 0.29-0.99). Conclusions: Most Utah cancer survivors, and particularly those who received multiple modes of adjuvant treatment, are not participating in sufficient physical activity to improve longevity and quality of life after cancer.
