disaster, is not uncommon. African-Americans, however, "had approximately two-fold greater odds of screening positive for PTSD" after Hurricane Katrina than white people. It is deduced that African-Americans exhibit PTSD at higher frequencies than white people because they "were more likely to experience frequent mental distress." For example, African-Americans "report more negative events and chronic stressors--witnessing violence, receiving bad news, death events, lifetime major discrimination, daily discrimination--than whites, which negatively affects their mental health." African-Americans "are more segregated than any other racial/ethnic group in the United States, and racial segregation is associated with poorer quality housing and neighborhoods that have limited resources to enhance health and well-being." Another study found that the "[b]lack race was associated with greater symptom severity" of PTSD than other races. It is known that "[m]inority status itself has been shown to increase the risk of PTSD after trauma, though this effect may be largely because of differential exposure to poverty in violence." Additionally, the "largely Black population of New Orleans bore a disproportionately heavy burden of pre disaster chronic disease complicated by inadequate health care access."
