Abstract B111: Previous mammography experience as a predictor of mammography adherence among Hispanic/Latinas living in the Northeast United States

Background: Similar to non-Hispanic Black women, Hispanic/Latino women are more likely to be diagnosed with later-stage breast cancer than White women, and their mammography screening rates are lower than those of both groups. Although the literature generally focuses on women9s behavior to identify predictors of mammography screening, we hypothesized that selected factors associated with prior mammography experience would impact future screening. From a large prospective study of cancer screening in Hispanic/Latinas living in the Northeast US, the purpose of this investigation was to determine how previous mammography experiences influenced adherence to mammography screening guidelines over 2.5-4 years of follow-up. Methods: Among 1,456 community-living Hispanic/Latinas ages 40 to 75 who had received at least one screening mammogram at the time of their baseline interview and consented to medical record review, we considered “mammography experience” in predicting annual screening mammography (documented screening mammogram within 12 months + 1-month lag time), in accordance with recommendations promulgated by the American Cancer Society (and widely followed) during the study period. Using multivariate logistic regression, we identified independent predictors of adherence to recommended guidelines after adjusting for core sociodemographic, access to care, and medical factors. Key predictors included characteristics of provider (gender, race/ethnicity), ease of communication and use of interpreters, being treated with respect, believing that mammography-related pain was minimized as much as possible, communication of results, and general satisfaction. Odds Ratios (ORs) and 95% Confidence Intervals (CI) are reported. Results: 54% of Hispanic/Latino women were adherent to recommended mammography screening guidelines over the follow up period. Although needing help with communicating with medical staff and not speaking the same language as the radiologic technologist were significant in bivariate analyses, only 2 “experience” variables were significant predictors after multivariate adjustment: 1) Women who were told the results of their earlier mammogram at the time of the test were less likely (OR= 0.80; 95% CI 0.63, 0.97) to adhere to annual screening guidelines compared to patients who were not told their results; and 2) compared to women who did not have a usual care provider, having a female doctor increased a woman9s odds of being compliant with recommended guidelines (OR = 1.40, 95% CI 1.05, 1.77), whereas having a male usual care provider did not (OR = 0.86, 95% CI 1.05, 1.77). Conclusion: In a prospective look at adherence to mammography screening guidelines in Hispanic/Latino women living in the Northeast US, having a female usual care provider was associated with adherence to mammography screening guidelines. This finding requires further study, particularly in this subpopulation. Citation Format: Beth A.
