Effects of at-risk alcohol use on nighttime blood pressure, urinary catecholamines, and sleep quality in midlife adults.

Background: The association between alcohol and hypertension has been predominantly based on office blood pressure (BP) measurements. However, little is known about the effect of alcohol use on nighttime BP and the underlying mechanisms. The purpose of this study was to investigate the effects of at-risk alcohol use on nighttime BP, urinary catecholamines, and sleep quality in midlife adults.
