Abstract

OBJECTIVE/BACKGROUND:

Sleep plays a vital role in maintaining homeostasis and promoting individual health. This study aimed to investigate the trends of sleep duration in Korean adults.

PATIENTS/METHODS:

We collected data from individuals who were adults (≥18 years) and participated in three cycles (2007-2009, 2010-2012, and 2013-2015) of the Korea National Health and Nutrition Examination Survey (KNHANES) for the analysis of self-reported sleep duration pattern. A total of 51,545 adults (21,937 men and 29,608 women) were included.

RESULTS:

Sleep duration decreased among both men and women from 2007 to 2009 KNHANES to 2013-2015 KNHANES. Sleep duration differed by age group and sex. Moreover, sleep duration declined among middle-aged (30-49 years old) and older (50-64 years old) men and young (18-29 years old) and middle-aged (30-49 years old) women, although not among older and elderly women.

CONCLUSIONS:

The young and middle-aged adult groups (18-49 years old) showed a significant decline in sleep duration in the KNHANES 2007-2015.
