Exploring the role of being overweight or obese in participation in mammographic breast screening in New South Wales: A validation of self-reported breast screening participation in the ALSWH.


Overweight and obese women are at higher risk of breast cancer and worse outcomes, yet preliminary data indicates breast screening participation is lower in this group. Approximately 47% of the female NSW population is overweight or obese. This project intends to link BreastScreen NSW data with longitudinal BMI data from the 1946-51 cohort to examine how weight affects screening at different time points. This analysis is significant as it may identify a currently under-acknowledged high risk population who are not participating in breast-screening. This study will also aims validate self-reported ALSWH screening data.
