RT Journal Article SR Electronic T1 Non-reporting and inconsistent reporting of race and ethnicity in articles that claim associations among genotype, outcome, and race or ethnicity JF Journal of Medical Ethics JO J Med Ethics FD BMJ Publishing Group Ltd and Institute of Medical Ethics SP 724 OP 728 DO 10.1136/jme.2005.014456 VO 32 IS 12 A1 H Shanawani A1 L Dame A1 D A Schwartz A1 R Cook-Deegan YR 2006 UL http://jme.bmj.com/content/32/12/724.abstract AB Background: The use of race as a category in medical research is the focus of an intense debate, complicated by the inconsistency of presumed independent variables, race and ethnicity, on which analysis depends. Interpretation is made difficult by inconsistent methods for determining the race or ethnicity of a participant. The failure to specify how race or ethnicity was determined is common in the published literature. Hypothesis: Criteria by which they assign a research participant to racial or ethnic categories are not reported by published articles. Methods: Methods were reviewed for assigning race and ethnicity of research participants in 268 published reports reporting associations among race (or ethnicity), health outcome and genotype. Results: Of the 268 published reports reviewed, it was found that 192 (72%) did not explain their methods for assigning race or ethnicity as an independent variable. This was despite the fact that 180 (67%) of those reports reached conclusions about associations among genetics, health outcome and race or ethnicity. Conclusions: More attention needs to be given to the definition of race and ethnicity in genetic studies, especially in those diseases where health disparities are known to exist.
