Gender Difference in Sleep Problems: Focused on Time Use in Daily Life of Korea

Abstract

Korea is well-known as one of the most sleepless country on the globe. Given the fact that sleep is closely connected with various health outcomes, we examined which group is more likely to experience sleep disorder problems within the context of time use. This study sets out to describe the differences in sleep disorder patterns between Korean men and women. In this study, we also tried to identify important socio-demoraphic factors and wake activity time use factors that might account for the sleep problem (short sleep/oversleep) and gender differences in sleep. Data from the original 2004 Korean Time Use Survey were used for this study (n = 16,958). Fifty-two percent of the respondents were women; the age range of the sample was 25–59 years. Results showed us that there was no gender differences found in dimension of short sleep. Still, women were less likely to be over sleeper rather than men, implying the existence of gender inequality in rest/free time. Results from the multinomial regression model showed that, although there were similarities in the impact of relevant factors, men’s sleep was more likely to be disturbed by their work role, while women’s sleep was affected by their work and family role. In this study, it was found that the gender difference in sleep problems was associated with time use, and especially the social roles that men and women occupied.
