Habitual sleep duration associated with self-reported and objectively determined cardiometabolic risk factors.

ABSTRACT:

Background

Self-reported short or long sleep duration has been associated with adverse cardiometabolic health outcomes in laboratory and epidemiologic studies, but interpretation of such data has been limited by methodologic issues.

Methods

Adult respondents of the 2007-2008 US National Health and Nutrition Examination Survey (NHANES) were examined in a cross-sectional analysis (N=5649).
