N1 - Funding Information:
The authors would like to thank the Bureau of Health Statistics and Registries at the Pennsylvania Department of Health for providing data on cancer survivors and to the Community Sciences and Health Outcomes Shared Resource, supported by the Penn State Clinical and Translational Science Institute, for generating the sampling strategy of the study (NIH UL1 TR002014). Dr. S.M. Bluethmann is supported by a Mentored Research Scholar Grant in Applied and Clinical Research, MSRG-18-136-01, from the American Cancer Society. Portions of this study were previously presented at the 2018 annual meetings of the Society of Behavioral Medicine and American College of Sports Medicine. S.M. Bluethmann led the conceptualization, design, analysis, and writing of this manuscript. W. Foo assisted with analysis and data management for the study. S.K. Mama and R.M. Winkels contributed to interpreting data and writing the manuscript. K.H. Schmitz provided senior leadership on study design, concept, data interpretation, and writing of this manuscript. All coauthors consented to submission of this manuscript. The authors declare that they have no conflicts of interest.

N2 - Purpose: (a) To describe the relationship of multimorbidity and physical activity (PA) in cancer survivors and (b) to explore perceived disability and PA in middle-aged and older survivors. Methods: The authors analyzed the data from cancer survivors (N = 566), identified using the Pennsylvania Cancer Registry, who responded to a Behavioral Risk Factor Surveillance System-derived questionnaire. They created age groups (e.g., 45-54 years, 55-64 years, 65-74 years, and 75 years and older) and calculated a composite score of eight common comorbidities (e.g., chronic obstructive pulmonary disease, heart disease) to assess multimorbidity. Logistic regression was used to estimate the association of demographic and behavioral/clinical risk factors (e.g., multimorbidity, perceived disability, body mass index) with PA. Results: Most respondents were females (62%), older (mean age = 68 years) and represented diverse cancer sites, including breast (n = 132), colorectal (n = 102), gynecologic (n = 106), prostate (n = 111), and lung (n = 80). PA participation was mixed; 44% of survivors reported achieving >150 min of aerobic PA, but half of lung and 37% of gynecologic survivors reported no PA (0 min/week). Higher multimorbidity (odds ratio = 0.82, confidence interval [0.69, 0.98], p <.05), obesity (odds ratio = 0.51, confidence interval [0.30, 0.86], p <.05), and perceived disability (odds ratio = 0.49, confidence interval [0.32, 0.77], p <.001) were negatively associated with PA participation. Strength training was suboptimal across all survivors. Conclusion: Most older survivors experienced comorbid conditions, and this was associated with less PA. Survivors who perceived themselves as disabled or who were obese were half as likely as others to participate in PA. This suggests an increasing need to address both physical and psychological limitations in designing PA interventions for real-world needs. Exercise interventions that address the unique needs of older survivors for multimorbidity, obesity, and perceived disability may strengthen opportunities for PA.
