The purpose of this study was to identify the factors related to short and long sleep duration. This study analyzed cross-sectional data collected from 10,590 Korean adults aged 19 years and older who participated in Korean national health and nutrition survey VI (2014-2015). Hierarchical multinomial logistic regression examined whether variables in 4 domain-demographic, socioeconomic, lifestyle and health related factors-were associated with short or long sleep duration. 42.4% and 7.2% of the population reported short and long sleep respectively. Older age, job, stress, poorer self reported health, pain or discomfort and obesity were associated with short sleep duration. Older age, being unmarried, divorced or widowed, lower levels of education, lower levels of income, job, self reported health, depression or anxiety were associated with long sleep duration. Interventions for adequate sleep duration could be considered for health.
