Jennifer Ailshire (USC/UCLA) and co-authors examine sleep duration trends in U.S. adults
"Nearly One-Third of Americans Sleep Fewer Than Six Hours Per Night" - Smithsonian. 12/26/2018.
"Of those polled in 2017, 40.9 percent of African-Americans, 32.9 percent of Hispanics and 30.9 percent of Caucasians said they typically slept fewer than six hours per night. The rapid increase evident in these figures—up 6.5 percentage points amongst African-Americans and 7 percent amongst Hispanics from 2004—means these groups are not only suffering from a more severe sleep surfeit, “but at a faster rate over time,” says study co-author and University of Southern California gerontologist Jennifer Ailshire."
