Introduction: Latino cancer survivors engage in less physical activity than non-Latino cancer survivors. Previous research has shown that higher acculturation is associated with higher leisure-time physical activity among foreign-born Latinos. However, there is limited research on the association of acculturation with leisure-time aerobic and muscle-strengthening activity among foreign-born Latino cancer survivors, for whom the acculturation and physical activity association may be influenced by lifestyle changes related to cancer survivorship. Therefore, we examined whether acculturation was associated with aerobic and muscle-strengthening physical activity among Latino cancer survivors. Methods: We used cross-sectional data from the 2008-2015 National Health Interview Survey (n=1,293). Participants were individuals that self-identified as Latino, ≥20 years old, and not pregnant. Cancer diagnosis was assessed by the survey variable, “Ever told by a doctor you have cancer?” Nativity (US-born, foreign-born) and years living in the US (<10 years living in US, ≥10 years living in US) were used as proxies of acculturation. Aerobic physical activity was measured based on self-reported minutes of moderate-to-vigorous aerobic physical activity engaged in per week, then categorized into none, some activity, and meeting the aerobic activity guideline. Muscle-strengthening activity was measured based on self-reported frequency of muscle-strengthening activity per week, then categorized into meeting and not meeting the muscle-strengthening guideline. Cutoffs for meeting the aerobic and muscle-strengthening guidelines were based on the 2018 Physical Activity Guidelines for Americans. Logistic regression models were used to examine the association of acculturation with aerobic and muscle-strengthening activity among Latino cancer survivors. Models were adjusted for age, sex, education, and Hispanic subgroup. Results: Approximately 33% of the sample reported meeting the aerobic activity guideline, and 15% reported meeting the muscle-strengthening guideline. Foreign-born cancer survivors living in the US <10 years were significantly less likely to meet the aerobic physical activity guideline (Odds Ratio [OR]: 0.26, 95% Confidence Interval: 0.10-0.67) and to engage in some aerobic activity (OR: 0.38, 95% CI: 0.16-0.89), compared with US-born Latino cancer survivors. There was no significant association between acculturation and muscle-strengthening activity. Conclusion: Recent Latino immigrants with a history of cancer are less likely to engage in aerobic physical activity compared with their US-born counterparts. Research is warranted on the barriers to aerobic physical activity among recent Latino immigrant cancer survivors.
