Black race and Hispanic ethnicity were associated with lower rates of sustained virologic response (SVR) to interferon-based treatments for chronic hepatitis C virus infection, whereas Asian race was associated with higher SVR rates compared to white patients. We aimed to describe the association between race/ethnicity and effectiveness of new direct-acting antiviral regimens in the Veterans Af...

We analyze the interaction of black-white race with physical and socioeconomic characteristics in the US marriage market, using data from the Panel Study of Income Dynamics. We estimate who inter-racially marries whom along anthropometric and socioeconomic characteristics dimensions. The black women who inter-marry are the thinner and more educated in their group; instead, white women are the f...

We examined whether or not priming racial identity would influence Black-White biracial individuals' ability to visually search for White and Black faces. Black, White, and biracial participants performed a visual search task in which the targets were Black or White faces. Before the task, the biracial participants were primed with either their Black or their White racial identity. All particip...

Let k be a natural number. We introduce k-threshold graphs. We show that there exists anO(n) algorithm for the recognition of k-threshold graphs for each natural number k. k-Threshold graphs are characterized by a finite collection of forbidden induced subgraphs. For the case k = 2 we characterize the partitioned 2threshold graphs by forbidden induced subgraphs. We introduce restricted, and spe...

This paper explores the relationships behind previous findings that Federal Reserve interest rate policies have a larger impact on black unemployment compared to white unemployment. Most earlier studies employ a VAR methodology, which does not, however, permit a structural analysis of key relationships. This paper accounts for the endogeneity of unemployment, inflation, and the federal funds ra...

BACKGROUND Previous studies suggested that the racial differences in U.S. suicide rates are decreasing, particularly for African Americans, but the cause behind the temporal variations has yet to be determined. This study aims to investigate the long-term trends in suicide mortality in the U.S. between 1983 and 2012 and to examine age-, period-, and cohort-specific effects by gender and race. ...

Heart rate (HR) has been shown to predict future blood pressures (BP) in studies in adults. We explored the relation of HR to future BP levels in a cohort of 344 black and 456 white schoolchildren ages 5 to 19 years, to examine the hypothesis that HR predicts subsequent BP even very early in life. After making baseline measurements, BP was assessed longitudinally 1 to 24 additional times (mean ...

BACKGROUND AND PURPOSE At age 45 years, blacks have a stroke mortality ≈3× greater than their white counterparts, with a declining disparity at older ages. We assess whether this black-white disparity in stroke mortality is attributable to a black-white disparity in stroke incidence versus a disparity in case fatality. METHODS We first assess if black-white differences in stroke mortality wit...

As stroke mortality rates according to race were not known in Brazil, data on mortality for the year 2010 was collected from the Mortality Information System of the Brazilian Ministry of Health. Cerebrovascular mortality rates adjusted for age (per 100,000) were calculated with a confidence interval of 95% (95%CI) by sex and race/skin color. The differences between races were significant for me...
