Sociocultural factors associated with physical activity in Black prostate cancer survivors

Purpose: Prostate cancer disproportionately affects Black men. Physical activity protects long-term health and quality of life outcomes in prostate cancer survivors. This study aimed to identify sociocultural factors related to physical activity among Black prostate cancer survivors to inform culturally tailored intervention development.

Methods: This secondary analysis included data from 257 men who identified as Black or African American and were diagnosed with prostate cancer between 2013 and 2018. Participants completed validated self-report measures of perceived history of racial discrimination, religiosity, fatalism, sociodemographic (e.g., age, ethnicity, income) and clinical characteristics (e.g., years since diagnosis, comorbidity burden), and leisure-time physical activity. Regression analyses were conducted to examine the associations between sociocultural factors and mild, moderate, and vigorous physical activity.

Results: Participants were on average 68.7 years old (SD = 7.7), and most were non-Hispanic (97.3%), married (68.9%), reported an annual household income above $50,000 (57.1%), received at least some college education (74.1%), and were overweight or had obesity (78.5%). Participants reported on average 88.1 (SD = 208.6) min of weekly mild physical activity, and most did not meet guidelines for weekly moderate (80.5%) or vigorous (73.0%) physical activity. After adjusting for covariates, older age and greater religiosity were associated with mild physical activity (ps ≤ 0.05). Higher levels of fatalism were associated with lower odds of meeting guidelines for moderate physical activity (OR = 0.87, 95% CI = 0.77-0.99).

Conclusions: Sociocultural factors such as religiosity and fatalism may be associated with some forms of physical activity in Black prostate cancer survivors. These findings suggest that incorporating faith-based practices into health behavior interventions may be appropriate for this population.
