Abstract 7345: Differences in complete screening adherence across age, income, and education groups

Abstract There is limited knowledge of the sociodemographic characteristics of individuals who are fully adherent to all recommended cancer screening tests. Understanding these cancer screening gaps may provide insights into subpopulations who may benefit from interventions to increase overall early cancer detection. The Cancer Prevention Study- 3 is a prospective cohort study established by the American Cancer Society (enrollment 2006-2013). Between enrollment and 2018, cancer-free participants reported cancer screening tests (mammography, colonoscopy, sigmoidoscopy, stool testing, and low dose lung computed tomography (CT) scans) and year(s) of each screening. Eligibility for each test was determined using 2018 American Cancer Society guidelines. For each person, an adherence score was calculated based on the number of eligible screenings and whether they were adherent. Patterns of adherence were compared across age, education, and income groups using an ANOVA to determine statistical significance. 129, 927 individuals were included in this analysis. Men had a higher proportion of no screening adherence (17%), and complete adherence (81%) compared to women, 8% and 67%, respectively. For those 45-55 years old (N=37, 393), approximately 46% were not completely adherent, compared to only 24% of those > 55 years old. Likewise, study participants who had an annual income <$50, 000 or a high school degree or less, had a higher proportion of individuals with partial or no adherence versus those who had an annual income ≥$100, 000 or a college degree or higher. Given the significant differences in adherence by age, income level, and education, consideration of bundled screening (getting multiple screenings during a single visit), especially for some populations, may provide an opportunity to increase complete screening adherence, potentially reducing the number of cancers diagnosed at an advanced stage and increasing survival.
