Sleep duration was assessed using a self\u2010reported questionnaire, and the participants with sleep duration of \u2265\u20099\u2009h were assigned to the group with long sleep duration. Physical activity was measured using a triaxial accelerometer and each participant's duration (min\/day) of moderate\u2010 to vigorous\u2010intensity physical activity (MVPA) was calculated. Logistic regression analysis was used to estimate the odds ratio (OR) and 95% confidence interval (CI) of sarcopenia.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Of the 2855 participants, 118 (4.1%) were classified as having sarcopenia. Long sleep duration was significantly associated with sarcopenia after adjusting for covariates (OR: 2.09, 95% CI: 1.01\u20134.29, Model 1). In Model 2, in which MVPA was also adjusted for, this association was weaker (OR: 2.02, 95% CI: 0.98\u20134.18). After dividing the participants according to MVPA, while long sleep duration was not associated with sarcopenia in participants with higher physical activity (OR: 1.37, 95% CI: 0.47\u20133.99), it was in those with lower physical activity (OR: 3.34, 95% CI: 1.21\u20139.21).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
