To determine the association of radiological and symptomatic osteoarthritis with sleep duration in a representative sample of the Korean population. Using data from the national cross-sectional fifth Korea National Health and Nutrition Examination Survey 2010-2012. Of the 16,528 participants in KNHANES-V, 8,918 were adults aged≥ 50 years who had completed the survey questions on sleep duration and osteoarthritis, and had diagnostic X-ray results. We evaluated the association between sleep duration as the primary predictor for osteoarthritis involving the hip, knee, and spinal joints. A complex sample logistic regression analysis was performed to adjust for the covariates. Proportions of participants with total daily sleep duration of ≤6 hours, 7-8 hours, and ≥9 hours were 47.1%, 45.2, and 7.7%, respectively. The rate of osteoarthritis diagnoses in the ≤6 hours, 7-8 hours, and ≥9 hours of sleep duration groups was 24.1%, 17.6%, and 21.8%, respectively (p
