Weekday and weekend sleep duration and mortality among middle-to-older aged White and Black adults in a low-income southern US cohort.

ABSTRACT:

Introduction

Both short and long sleep have been associated with higher mortality. However, most studies are conducted in predominantly White or Asian populations and little is known about the sleep-mortality relationship in Blacks. Given the high prevalence of short and long sleep in Blacks, it is important to examine the health effects of sleep in this population.
