Trends in colorectal cancer screening compliance and incidence among 60‐ to 74‐year‐olds in China

Abstract

Abstract Background Compliance with colonoscopy among elderly individuals participating in colorectal cancer (CRC) screening programs is unsatisfactory, despite a high detection rate of bowel‐related diseases. In this study, our aim was to analyze the impact of risk factors on the trends of compliance and detection rates in colonoscopy among high‐risk individuals aged 60–74. Methods A retrospective study was conducted on the high‐risk individuals aged 60–74 participating in the 2021 CRC screening program in Tianjin, China. Logistic regression analyses, including both univariate and multivariate analyses, were performed to explore the impact of different risk factors on colonoscopy compliance among the high‐risk individuals. Besides, the study investigated the influence of various risk factors on the detection rates of bowel‐related diseases among the high‐risk individuals who underwent colonoscopy. Results A total of 24,064 high‐risk individuals were included, and 5478 individuals received a free colonoscopy, with an overall compliance of 22.76%. Among them, the adenoma detection rate was 55.46%. Males and individuals with a positive FIT had high compliance and detection rates for CRC, advanced adenomas (AA), advanced colorectal neoplasia (ACN), and colorectal neoplasm (CN). Individuals aged 70–74 were associated with low compliance but high CRC, ACN, and CN detection rates. Individuals who reported a history of chronic constipation, bloody mucous, and CRC in first‐degree relative showed high compliance but no significantwere associated with the detection rates of CRC, AA, and CN. Conclusion This study reported several risk factors associated with the screening behaviors for CRC. Patterns and trends in CRC, AA, ACN, and CN compliance and detection rates correlate with risk factors.
