- Black adults are more likely than white adults to skimp on sleep, and the sleep gap is especially wide for black professionals, according to a study out of the Harvard School of Public Health. Based on the results of a nationally representative survey of nearly 140,000 men and women, 29 percent of adults routinely get fewer than seven hours of sleep each night. Sleep skimping was more common among blacks in general than whites — 37 percent compared with 28 percent — but researchers found an even more noticeable difference between professionals: 42 percent of black professionals reported fewer than seven hours of sleep each night compared with 26 percent of white professionals. A sleep gap was not found among food and retail workers, and the overall racial gap was similar in men and women (American Journal of Epidemiology, online Sept. 9).
- White public school teachers in the New York metropolitan area appear to give more positive feedback to minority students than to white students for equal work, concludes research led by Rutgers University investigators. In the study of 113 white middle school and high school teachers in the New York metropolitan area, participants read and commented on a poorly written student essay. Results showed that the teachers displayed a "positive feedback bias," providing more praise and less criticism when they thought the essay was written by a minority student than by a white student.

- Cross-ethnic friendships may help youths feel safer, according to a study led by researchers at the University of California, Los Angeles, and the University of Groningen in the Netherlands. The study looked at 536 Latino and 396 black sixth-graders from 66 classrooms in 10 urban U.S. middle schools in predominantly low-income, ethnically diverse neighborhoods. The students reported on the number of same- and cross-ethnic friends they had, how vulnerable they felt, the quality of their friendships and their ethnic identity. The researchers found that cross-ethnic friendships increased as the diversity of classrooms rose, and that the students who reported these friendships also felt less lonely, less victimized by peers and safer at school than those with only same-ethnic friendships (Child Development, online Sept. 23).
- Young adult blacks males, especially those with higher levels of education, are less likely to seek mental health services than their white counterparts, according to researchers at Michigan State University. The study examined two samples of national data—one collected in 1994 and 1995 consisting of 6,504 adolescents ages 13 to 18, and another collected in 2001, with 4,881 adults ages 18 to 26. The analysis also found that while whites who had previously used mental health services were more likely to receive additional services, the opposite was true for blacks.

- Black and Hispanic high school students who work part time are less likely to see their grades suffer than white non-Hispanic students who work part time, finds research out of the University of Michigan. In the study of nearly 600,000 students from around the country, researchers found that grade-point averages among white and Asian-American students dropped dramatically the more hours they worked, while the GPAs of Hispanic and black students showed less connection with hours worked. In addition, among high school students who worked long hours at a part-time job, black and Hispanic students from lower income households were less likely to smoke and drink than affluent white or Asian-American students who worked long hours (Developmental Psychology, online Jan. 14).
