Rural-urban disparities and trends in cancer screening: an analysis of Behavioral Risk Factor Surveillance System data (2018-2022).

Background: Despite evidence of the benefit of routine cancer screenings, data show a concerning decline in cancer screening uptake for multiple cancers. This analysis aimed to examine rural-urban differences in recent trends for being up-to-date with screenings for breast, cervical, and colorectal cancers.

Methods: We used 2018, 2020, and 2022 Behavioral Risk Factor Surveillance System data to assess up-to-date cancer screening status among eligible adults in the United States. We calculated weighted prevalence estimates overall and stratified by county-level rural-urban classification. We used survey-weighted multivariable logistic regression models to examine rural-urban disparities in cancer screening up-to-date status by year.

Results: Prevalence of being up-to-date with each cancer screening was lower in 2022 than it was in 2018. The largest decline in screening overall was for cervical cancer, which dropped from 81.89% in 2018 to 47.71% in 2022. Rural-urban disparities were observed for breast cancer screening from 2018 to 2022, with the odds of up-to-date screening being 14% to 27% lower for rural populations than for urban populations. For colorectal and cervical cancers, the odds of being up-to-date with screenings were lower for rural populations in 2018 and 2020, but no statistically significant difference was observed in 2022 (colorectal screening odds ratio = 0.96, 95% CI = 0.90 to 1.02; cervical screening odds ratio = 0.97, 95% CI = 0.93 to 1.03).

Conclusion: There is a concerning trend of decreasing uptake of cancer screenings that will challenge future efforts in cancer prevention and control. There is a need to better understand the factors contributing to the decline in cancer screening update.
