Concurrent cancer screening participation and associated factors among Canadian women: Insights from a cross-sectional study

= 10,426). Multivariable logistic regression evaluated factors associated with colorectal cancer screening among "screen-aware" women. Multinomial logistic regression assessed factors related to full (all three), partial (any two), single, or non-participation across screening programs, using "no screening" as the reference.ResultsAlthough the majority of women (87%) participated in at least one screening program, only 27% reported full participation. Colorectal cancer screening (53.7%) lagged behind breast and cervical cancer screening (∼64%). Among "screen-aware" women, older age (adjusted odds ratio 1.50, 95% confidence interval 1.31-1.71), higher income, self-rated health as "great" (adjusted odds ratio 1.31, 95% confidence interval 1.05-1.63), and having a regular healthcare provider (adjusted odds ratio 3.29, 95% confidence interval 2.45-4.40) were associated with higher colorectal cancer screening participation. Having multiple chronic conditions reduced colorectal cancer screening likelihood (adjusted odds ratio 0.72, 95% confidence interval 0.55-0.94). Higher income, self-rated health, having a regular healthcare provider, and physical activity increased the odds of full screening participation, while smoking and Asian identity reduced the odds.ConclusionsColorectal cancer screening uptake remains low among Canadian women, even those participating in other cancer screenings. Socioeconomic, health-related, and systemic factors influence concurrent screening participation. Tailored interventions addressing identified barriers and promoting equitable access to screening are crucial for improving cancer prevention efforts.
