Women's Reactions to Breast Density Information Vary by Sociodemographic Characteristics

Abstract

Background: Breast density information aims to increase awareness of breast density and its risks and to foster more informed future breast screening decisions among women with dense breasts. We explored associations between such information and outcomes including anxiety, confusion, or feeling informed, and whether they varied by race/ethnicity or literacy, or differentially affected future mammography plans.

Methods: A national telephone survey of a diverse sample of women previously informed of personal breast density (N = 1,322) assessed reactions to receipt of breast density information and future mammography plans.

Results: Most women (86%) felt informed after receiving personal breast density information; however, some felt anxious (15%) or confused (11%). Reactions varied significantly by sociodemographics; non-Hispanic Black, Asian, and Hispanic women and women with low literacy were nearly two to three times more likely to report anxiety than non-Hispanic White women (all ps < .05). Asian women and those with low literacy less often felt informed and more often felt confused. Non-Hispanic Black and Asian women were nearly twice as likely to report that knowing their breast density made them more likely to have future mammograms. Women with low literacy were more likely to change mammography plans, with some being more likely and others less likely to plan to have future mammograms. Greater anxiety and confusion were associated with higher likelihood of planning future mammograms; those feeling informed were less likely to plan future mammography.

Conclusions: Differential reactions to breast density information are concerning if associated with disparate future screening plans. Future breast density education efforts should ensure that such information is readily accessible and understandable to all women in order to lead to desired effects.
