title: Racial and ethnic differences in mammography use among U.S. women younger than age 40.
abstract: OBJECTIVE
  Evidence-based recommendations for routine breast cancer screening suggest that women begin mammography at age 40, although some women receive a mammogram before that age. Little is known about mammography use among younger women, especially with respect to race and ethnicity.
  
  
  METHODS
  We used data from the 2005 National Health Interview Survey to examine racial/ethnic differences in mammography use among U.S. women ages 30-39. We examined descriptive characteristics of women who reported ever having a mammogram, and used logistic regression to estimate associations between race/ethnicity and mammography use among women at average risk for breast cancer.
  
  
  RESULTS
  Our sample comprised 3,098 women (18% Hispanic, 13% non-Hispanic [NH] black, 69% NH white), of whom 29% reported having ever had a mammogram. NH black women were more likely than NH white women to report ever having a mammogram and receiving multiple mammograms before age 40 among women of average risk. Patterns of mammography use for Hispanic women compared to NH white women varied.
  
  
  CONCLUSIONS
  Findings suggest differential utilization of mammograms by race/ethnicity among women outside current recommendations and of average risk. Future studies should examine the role of practice patterns and patient-provider communication.
