Mammography Screening Beliefs and Knowledge among a Multi-ethnic Sample of Low-income, Uninsured Women.

The purpose of this study was to examine screening mammography prevalence and its associated beliefs among a multi-ethnic sample of low-income, uninsured women. Data pertaining to the sample's demographic characteristics, mammography screening history and beliefs, and knowledge on recommended screening age were analyzed (n=533). Overall, 22.1% of the participants had never been screened. Black women were more likely than others to have never been screened, White women were more likely to be overdue, and Hispanic women were more likely to report recent screening. Fear of not knowing what will be done during mammography consistently predicted screening among the racial/ethnic groups. Concerns about "people doing mammograms being rude to women" had the highest negative correlation with mammography among Hispanic women. A majority of the sample believed that screening should begin at age 40. Interventions to increase screening mammography must incorporate information about the screening procedure and be sensitive to cultural differences in screening barriers.
