Self-reported vs. Objectively Measured Sleep

SSS research scientist W. Braxton Jackson II is among authors of an article in Sleep that identifies systematic biases across groups in objectively and subjectively measured sleep duration in the Multi-Ethnic Study of Atherosclerosis. Self-reported sleep duration overestimated objectively measured sleep across all races, and overestimation was significantly greater in whites compared with blacks. Therefore, sleep measurement differences should be considered when comparing sleep indices across racial/ethnic groups. Other authors of the article include researchers from the National Institute of Environmental Health Sciences, University of Pittsburgh, University of Minnesota, Brigham and Women’s Hospital, Harvard Medical School, and Harvard School of Public Health.
