We conducted a telephone survey of randomly selected Latinas (n = 208) and Anglo women (n = 222) to determine predictors of mammography use. The cooperation rate was 78.5%. Relatively high proportions of Latinas (61%) and Anglo women (79%) reported mammography use within the past 2 years. A logistic regression analysis revealed that knowledge and attitudes did not independently predict use. On the other hand, having health insurance, being married, and being Latino were consistent independent predictors. We conclude that mammography use among Latinas and Anglo women is increasing. However, further gains in use must address difficult barriers such as lack of health insurance.
