Abstract

Introduction Colorectal cancer (CRC) is a leading cause of cancer-related deaths globally, with early detection significantly improving treatment outcomes. Understanding the factors influencing the decision to participate in colorectal cancer screening programs can help design interventions to improve these programs. Method This study investigates factors influencing CRC screening participation among average-risk individuals aged 50–70 years in Isfahan province, utilizing data from the comprehensive E-health information system. Employing Andersen’s Behavioral Model, the study examines predisposing, enabling, and need-for-care factors. A logistic regression model was used to identify significant predictors of screening participation. Results The analysis in this study includes 808,978 average-risk individuals in Isfahan, with a mean age of 56.67 years (SD = 7.17). Results indicate that younger age, male gender, marital status, health insurance coverage, flexible work time pattern, Iranian nationality, and high-risk lifestyles positively influence the probability of participation. The predictor screening analysis reveals that lifestyle, chronic disease, and education are the top three factors influencing participation, with lifestyle being the most dominant predictor. © 2025 Elsevier B.V., All rights reserved.
