Screening for colorectal cancer: using data to set prevention priorities

Area of Science:

• Public Health
• Epidemiology
• Cancer Prevention

Background:

• Colorectal cancer screening adherence varies by state.
• Within-state variability in screening rates is not well understood.
• Targeting public health efforts requires granular screening data.

Purpose of the Study:

• Assess county-level colorectal cancer screening rates in Missouri.
• Identify geographic disparities in screening adherence.
• Inform targeted public health interventions to improve screening rates.

Main Methods:

• Utilized 2008 and 2010 Behavioral Risk Factor Surveillance System data.
• Analyzed screening prevalence in Missouri adults aged 50-74.
• Employed multilevel logistic regression for county-specific estimates.

Main Results:

• Colorectal cancer screening prevalence ranged from 25% to 70% across Missouri counties.
• Significant within-state variability in screening adherence was observed.
• Data represented 78.5% of the state population across 37 counties.

Conclusions:

• State-level screening data masks substantial within-state disparities.
• County-level analysis is essential for effective public health targeting.
• Improved population survey data can enhance future screening analyses.
