Abstract

Background: The aim of this study was to investigate the association between sleep duration and dizziness in a representative Korean population.
Methods: We analyzed data from the Korea National Health and Nutrition Examination Surveys (2010?2012). A total of 12,499 adults who completed otolaryngologic examinations were evaluated.
Results: Both men and women with severely short sleep duration (≤ 5 hours) and severely long sleep duration (≥ 9 hours) tended to have higher dizziness prevalence. However, the adjusted odds ratio (OR) for sleep duration was only significant in women with dizziness after adjusting for confounders. Compared to that in an optimal sleep group (6?8 hr/day), the OR (95% confidence interval) for dizziness prevalence after adjusting for age and health behaviors (body mass index, smoking habit, alcohol consumption, level of exercise, metabolic syndrome, and tinnitus) was 1.473 (1.194?1.818) for the severely short sleep group (≤ 5 hr/day) and 1.472 (1.078?2.009) for the severely long sleep group (≥ 9 hr/day) only in women.
Conclusion: In the Korean population, dizziness was associated with shorter or longer sleep durations only among women. Further epidemiologic and experimental studies are necessary to clarify the impact of dizziness on sleep disorders.
