Background: This study was performed to evaluate the relation between serum vitamin D level and mean hours of sleep in Korean adults.
Methods: Th is study used the data collected from the 2011 Korea National Health and Nutrition Examination Survey. The total number of participants who were aged 19 years and over is 5,727. We used multiple linear regression analysis to evaluate relation between serum vitamin D level and mean hours of sleep. All results are adjusted for age, sex, body mass index, depression status, current status of smoking, lifetime drinking history, education level, income level, stress awareness, comorbidities, and quality of life index.
Results: Th e aim of this study was to investigate the association between serum vitamin D levels and the mean hours of sleep. Data was collected on participants in the 2011 Korea National Health and Nutrition Examination Survey. The following parameters were controlled by multivariate linear analysis: age, sex, body mass index, depression status, current status of smoking, lifetime drinking history, education level, income level, stress awareness, co-morbidities, and quality of life index. The results of this study demonstrate serum vitamin D levels are associated with the mean hours of sleep.
Conclusion: In this study, the serum 25-hydroxyvitamin D is related with mean hours of sleep. According to social change, vitamin D defi ciency is increasing. And it is suggested that this increase is associated with sleep disorders. For the treatment of these sleep disorders, it is expected that vitamin D intake have a positive impact.
