Racial differences in parents' distrust of medicine and research.

OBJECTIVE

To assess and compare the attitudes and trust that African American and white parents have toward their children participating in research.

DESIGN

Self-administered, cross-sectional survey of a convenience sample of parents.

SETTING

Primary Care Center at Children's Hospital of Pittsburgh from August 2004 through April 2005.

PARTICIPANTS

One hundred ninety parents (140 African American and 50 white parents).

OUTCOME MEASURE

Parental distrust of medical research as measured by a summative score of distrusting responses to 8 questions assessing trust in research.

RESULTS

African American parents had significantly greater distrust than white parents (67% vs 50%, P = .04). Education was also associated with having significantly greater distrust (74% of those with <high school education vs 44% of college graduates, P = .03). However, African American race remained a predictor of distrust even when education was controlled for (odds ratio, 2.25; 95% confidence interval, 1.01-5.01).

CONCLUSIONS

The degree of parental distrust toward medical research was significantly greater among African American parents. Parental distrust may be a barrier to enrollment of African American children in clinical research. Strategies for overcoming the higher level of distrust in African American parents are warranted for ensuring adequate representation of African American children in clinical research.
