Sleep irregularity, especially irregular sleep duration, is associated with measures of subclinical atherosclerosis, according to a study published in the Journal of the American Heart Association.

Dr Kelsie Full (PhD), from Vanderbilt University Medical Center in Nashville, Tennessee, and colleagues examined cross-sectional associations of actigraphy-assessed sleep duration and sleep timing regularity with subclinical atherosclerosis among 2032 participants from the Multi-Ethnic Study of Atherosclerosis Sleep Ancillary Study who completed seven-day wrist actigraphy.
