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.
