The 10th NSRR dataset went online earlier this month: Multi-Ethnic Study of Atherosclerosis (MESA) Sleep. The NSRR team worked closely with the Collaborative Health Studies Coordinating Center (CHSCC) to make these data available. We are excited about MESA because it marks our first dataset with both polysomnography and actigraphy!
Below is a short summary of the MESA project and some notes about the Sleep visit that took place between 2010 and 2012:
Multi-Ethnic Study of Atherosclerosis (MESA), is an NHLBI-sponsored 6-center collaborative longitudinal investigation of factors associated with the development of subclinical cardiovascular disease and the progression of subclinical to clinical cardiovascular disease in 6,814 black, white, Hispanic, and Chinese-American men and women initially ages 45-84 at baseline in 2000-2002. There have been four follow-up exams to date, in the years 2003-2004, 2004-2005, 2005-2007, and 2010-2011. Between 2010-2012, 2,237 participants also were enrolled in a Sleep Exam (MESA Sleep) which included full overnight unattended polysomnography, 7-day wrist-worn actigraphy, and a sleep questionnaire. The objectives of the sleep study are to understand how variations in sleep and sleep disorders vary across gender and ethnic groups and relate to measures of subclinical atherosclerosis.
