It is also noteworthy that very few studies explicitly examine the role of discrimination in accounting for racial disparities in health. Some early studies provided evidence that discrimination made an incremental contribution to SES in explaining disparities.81 A few recent studies find that perceived discrimination accounts for some of the racial disparities in health. This is evident for Maori-European disparities on four indicators of self-reported health in a national study of New Zealand,82 Aboriginal-non Aboriginal variations in self-reported physical and mental health in Australia,83 and in U.S. studies for black-white differences in health care trust,84 sleep quality and physical fatigue85 and Hispanic-white differences in PTSD symptoms.86
