Purpose: Latinas in low-resource settings face additional barriers to understanding mammographic breast density (MBD) implications. The authors compared MBD awareness and knowledge in Latinas from a safety-net clinic in Arizona with a national sample. Methods: Latinas 40 to 74 years of age were recruited within a safety-net clinic during screening mammography appointments from 2016 to 2019 (AZ cohort) and from a nationally representative online panel in 2017 (NS cohort). Surveys completed in either English or Spanish assessed awareness and knowledge of MBD. Chi-square tests and logistic regression were used for comparisons. Results: The NS cohort (n = 152) was older, more educated, more likely to have undergone prior mammography, and more likely to prefer English compared with the AZ cohort (n = 1,327) (P ≤ .03 for all) The NS cohort was more likely to be aware of MBD (32.6% versus 20.7%). Of those aware, the NS cohort was more likely to understand MBD's effect on masking (67.8% versus 37.0%) and breast cancer risk (72.2% versus 32.6%) compared with the AZ cohort (P ≤ .001 for all). Adjusting for age, education, screening history, and language, MBD awareness was similar between the two cohorts (adjusted odds ratio [ORadj], 0.95; P = .83), but knowledge of MBD as a masking factor (ORadj, 2.8; P = .03) and risk factor (ORadj, 7.2; P < .001) remained higher in the NS cohort compared with the AZ cohort. Conclusions: Differences in MBD awareness, but not knowledge, between Latinas in a low-resource setting compared with a national sample could be explained by age, education, screening history, and language preference, underscoring the need for tailored approaches to MBD education among Latinas.
