Introduction: Physical inactivity is a known risk factor for cancer morbidity and mortality, but its role in colorectal cancer survivors (CRCS) is understudied. Our objective was to determine which factors influence leisure time physical activity (LTPA) in CRCS.

Methods: Data was pooled from the 1997-2010 National Health Interview Survey, an annual, cross-sectional household survey representative of the US civilian non-institutionalized population (N=2,378). We evaluated compliance of LTPA in CRCS according to Healthy People 2010 (HP2010) recommendations. Multivariable analyses were performed to identify demographic and behavioral predictors of LTPA in CRCS.

Results: Compared to CRCS aged 50-59 years, those aged 71-80 and >80 years were less likely to comply with LTPA recommendations, [OR=0.52; (95%CI=0.29-0.91)] and (0.28; 0.15-0.52). Females, relative to males, were less likely to comply (0.65; 0.46-0.93). Relative to non-Hispanic Whites, Hispanics (0.48; 0.30-0.77) and Blacks (0.49; 0.27-0. 90) were less likely to comply. CRCS with > high school education (HSE) were more likely to comply than those with ≤ HSE (1.69; 1.23-2.32). Heavy drinkers were more likely to comply vs. light/moderate drinkers (3.07; 1.49-6.27); whereas former drinkers were less likely to comply (0.65; 0.46-0.92). Smoking and obesity status were not significant predictors of complying with LTPA recommendations.

Discussion: CRCS who were older, minorities, and women were less compliant with HP2010 recommendations for LTPA. Additional evidence regarding the impact of LTPA in the growing population of CRCS is urgently needed to inform public health interventions, as well as to improve the survival, quality of life, and recurrence of cancer.

Chronic disease management and prevention
Clinical medicine applied in public health
Epidemiology
Implementation of health education strategies, interventions and programs

Learning Objectives:
1. Examine demographic and behavioral predictors of leisure time physical activity in colorectal cancer survivors. 2. Identify colorectal cancer survivor groups at high risk for noncompliance with leisure time physical activity according to Healthy People 2010 recommendations. 3. Explore potential public health interventions for sedentary colorectal cancer survivors
