Age-dependent association between sleep duration and hypertension in the adult Korean population.

摘要

BACKGROUND: In Western countries, sleep deprivation has been reported to elevate blood pressure. Here, we examined whether this association is true also for an Asian population. METHODS: The study sample comprised 5,393 Korean adults aged 19-99 years who had participated in the 2005 Korean National Health and Nutrition Examination Survey. Hypertension was defined as a systolic blood pressure (SBP) >/=140 mm Hg or a diastolic blood pressure (DBP) >/=90 mm Hg, or regular use of antihypertensive medication. RESULTS: Among the participants, 1,345 subjects (24.9%) displayed hypertension. The median sleep duration was 7 h/day. In the young and middle-aged adults aged <65 years, the unadjusted odds ratio (OR) for hypertension was 1.5-fold greater in those with a sleep duration of /=65 years, no association was found between sleep duration and the risk of hypertension. Long sleep duration (>/=8 h) was not associated with hypertension in either the younger or older adults in this study. CONCLUSION: Short sleep duration (
