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 makes an incremental contribution to SES in explaining disparities (Williams et al. 2003). 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 (Harris et al. 2006a), Aboriginal–non Aboriginal variations in self-reported physical and mental health in Australia (Larson et al. 2007), and in U.S. studies for black-white differences in health care trust (Adegbembo et al. 2006), sleep quality and physical fatigue (Thomas et al. 2006) and Hispanic-white differences in PTSD symptoms (Pole et al. 2005).
