Sleep pattern disruptions have been reported to be associated with an increased risk of obesity. This studywas performed to investigate the association between sleep quality and sleep duration with dietary consumption, psychological factors, and obesity in Korean adults. A total of 288 Korean men and women who visited a public health center were included in this study. Data on general characteristics, health-related habits, psychological symptoms, dietary intake, and sleep patterns (including quality and duration) were collected using self-report questionnaires. Approximately half of the included Korean adults experienced sleep of low quality and short duration. Subjects who reported short sleep durations had a significantly higher weight (P=0.015), body mass index (P<0.001), and prevalence of obesity (P=0.012) than those reporting proper sleep durations. After adjustment for covariates, subjects reporting short sleep durations consumed more dietary carbohydrates (P=0.043) and higher levels of perceived stress (P=0.001), depression (P=0.001), and anxiety (P<0.001) than subjects reporting proper sleep durations. However, obesity-related variables, dietary intake and psychosocial symptoms did not differ significantly by reported sleep quality. The results of this study demonstrated that sleep duration but not sleep quality was associated with dietary macronutrient intake and psychological symptoms, which might affect obesity.
