Note. Participants are divided into two levels of risk based on estimates of their 10-year risk for developing breast cancer according to the NCI Breast Cancer Risk Assessment Tool [24]. SD = Standard Deviation. HS = high school.

“10-year BC risk” refers to the average estimated risk for developing breast cancer in the next 10 years for women in each condition.

Insurance status and history of prior mammograms varied significantly across conditions for women with an estimated 10-year breast cancer risk ≥ 1.5% and were also associated with likelihood of dropping out of the survey and with mammography intentions. These variables have been controlled for in analyses of mammography intentions for women with an estimated 10-year breast cancer risk ≥ 1.5%.
