Women
Area of Science:
- Radiology
- Public Health
- Behavioral Science
Background:
- Limited understanding of women's long-term mammography behavior exists.
- Previous studies on repeat mammography offer insufficient insights into temporal patterns.
Purpose of the Study:
- To investigate repeat mammography rates and behavioral patterns over time.
- To analyze factors influencing women's decisions for subsequent mammograms.
Main Methods:
- Interviewed 128 asymptomatic women aged 50-75 with prior mammograms.
- Assessed repeat mammography rates in Health Maintenance Organization (HMO) members and nonmembers.
Main Results:
- Repeat mammography rates were low before 21 months post-initial screening.
- Significantly higher repeat mammography rates were observed at 21 months or later.
Conclusions:
- Waiting up to two years for a second mammogram is a common choice.
- This behavior persists even among women receiving annual screening reminders and incentives.
