Mammography screening rates for women aged 40 and older remained stable overall from 2000 to 2006. However, utilization declined among insured women aged 40-59 and non-Hispanic white women, indicating subgroup disparities in breast cancer screening.
Area of Science:
- Public Health
- Epidemiology
- Health Services Research
Background:
- Previous research indicated a decline in regular mammogram use between 2000 and 2005.
- Mammography is a critical tool for early breast cancer detection.
Purpose of the Study:
- To assess mammography utilization trends from 2000 through 2006.
- To identify changes in screening patterns among different demographic and socioeconomic groups.
Main Methods:
- Analysis of Behavioral Risk Factor Surveillance System (BRFSS) data from 2000-2006.
- Estimation of age-adjusted mammography percentages by demographic and socioeconomic factors.
- Logistic regression to evaluate linear time trends in utilization.
Main Results:
- Overall age-adjusted mammography use among women aged 40+ remained stable (76.5% in 2000 vs. 76.1% in 2006).
- A statistically significant decline in mammography use was observed among insured women aged 40-59 years.
- Non-Hispanic white women also experienced a significant decline in mammography utilization.
Conclusions:
- Despite stable overall rates, mammography screening is not reaching recommended levels for a significant portion of women.
- Utilization patterns have leveled off or declined in specific subgroups, highlighting disparities.
- Addressing barriers to mammography access and utilization is crucial for improving breast cancer screening outcomes.
