title: Barriers to the use of genetic testing: a study of racial and ethnic disparities.
abstract: OBJECTIVE
  Racial and ethnic disparities in health are evident among a range of diseases and health care services. New genetic technologies are likely to increase these disparities as access to expensive genetic tests further widens the gap.
  
  
  METHODS
  Our analysis used data from a national representative sample collected in 2000. The total sample size for our analysis was 1724 men and women (consisting of 946 non-Hispanic whites, 392 Latinos, and 386 blacks) aged 18 to 91 years. Ordered logistic regression and binary logistic regression analysis were applied to investigate differences by race/ethnicity.
  
  
  RESULTS
  Results showed significant differences by racial/ethnic groups in knowledge and concerns about the potential misuse of genetic testing. A significant difference was also found between the types of health insurance coverage by race/ethnicity as well as significantly higher levels of mistrust in a physician and the medical system.
  
  
  CONCLUSIONS
  Our findings raise concern about several barriers among minorities and calls for a development of educational and communication strategies that facilitate in narrowing the gap between racial and ethnic groups.
