Police killings not only affect victims and their families but can have “pernicious spillover effects” onto the public at large, said the lead study author, Dr. Atheendar Venkataramani, an associate professor of medical ethics and health policy at the University of Pennsylvania.
The findings looked at survey results about sleep duration from 2013 through 2019 from two U.S. databases. The larger of the two, the Behavioral Risk Factor and Surveillance Survey, included responses from 181,865 Black and nearly 1.8 million white participants. The other, the American Time Use Survey, included data from 9,858 Black respondents and 46,532 white respondents.
