Hypothesis
Does area-level poverty rate affect colorectal cancer screening rates among individuals aged 50 and older?
Conclusion
Colorectal cancer screening rates vary significantly across different areas in Missouri, with higher poverty rates associated with lower screening rates.
Supporting Evidence
- 51.8% of Missourians aged 50 or older adhered to CRC screening recommendations.
- Nearly 15% of the total variation in CRC screening lay between ZIP5 areas.
- Persons in areas with ≥ 10% poverty had lower odds of CRC screening compared to those in areas with <10% poverty.
Takeaway
People living in poorer areas are less likely to get screened for colon cancer, even if they have similar backgrounds to those in wealthier areas.
Methodology
A multilevel study using data from the 2006 Missouri Behavioral Risk Factor Surveillance System to analyze the relationship between area poverty rates and colorectal cancer screening.
Potential Biases
Potential coverage bias due to reliance on traditional telephone surveys, which may miss low-income populations with only cell phones.
Limitations
The study relied on self-reported data, which may lead to underestimation of screening rates, and had a relatively low response rate.
Participant Demographics
Participants were Missouri residents aged 50 or older, with a diverse representation of race, income, and education levels.
