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.http://archpedi.ama-assn.org/cgi/content/abstract/163/2/10

Using a Family History Intervention to Improve Cancer Risk Perception in a Black Community.

Few studies examine the use of family history to influence risk perceptions in the African American population. This study examined the influence of a family health history (FHH) intervention on risk perceptions for breast (BRCA), colon (CRC), and prostate cancers (PRCA) among African Americans in Pittsburgh, PA. Participants (n = 665) completed pre- and post-surveys and FHHs. We compared their objective and perceived risks, classified as average, moderate, or high, and examined the accuracy of risk perceptions before and after the FHH intervention. The majority of participants had accurate risk perceptions post-FHH. Of those participants who were inaccurate pre-FHH, 43.3%, 43.8%, and 34.5% for BRCA, CRC, and PRCA, respectively, adopted accurate risk perceptions post-FHH intervention. The intervention was successful in a community setting. It has the potential to lead to healthy behavior modifications because participants adopted accurate risk perceptions. We identified a substantial number of at-risk individuals who could benefit from targeted prevention strategies, thus decreasing racial/ethnic cancer disparities
