Nowadays, it is hard to take enough sleep, so weekend catch-up sleep (CUS) may be an alternative option in modern society. To our knowledge, no previous studies reported the association between weekend CUS and metabolic syndrome, especially in the Korean population.Objective: We investigated the association between weekend CUS and the prevalence of metabolic syndrome in Korean adults (≥ 20 years old) with less than 6 hours of average weekday sleep.Patients and Methods: A total of 1,453 individuals were selected from the Korean National Health and Nutrition Examination Survey. Weekend CUS was divided into four categories: ≤ 0 hour, 0– 1 hour, 1– 2 hours, and ≥ 2 hours. Odds ratios (ORs) with 95% confidence intervals (CIs) were derived by univariate and multivariate logistic regression analyses.Results: Participants with weekend CUS ≥ 1 hour had decreased risk of metabolic syndrome in univariate analysis (CUS 1– 2 hours: OR: 0.413, 95% CI: 0.301– 0.568; CUS ≥ 2 hours: OR: 0.382, 95% CI 0.296– 0.493). Weekend CUS 1– 2 hours reduced the risk of metabolic syndrome in multivariate logistic regression analysis (OR: 0.552, 95% CI: 0.369– 0.823). Based on the age group analysis, weekend CUS ≥ 1 hour reduced the metabolic syndrome among those aged 20– 39 and 40– 65 (20– 39: CUS 1– 2 hours OR: 0.248, 95% CI: 0.078– 0.783, CUS ≥ 2 hours OR: 0.374, 95% CI: 0.141– 0.991; 40– 65: CUS 1– 2 hours OR: 0.507, 95% CI 0.309– 0.832 CUS ≥ 2 hours OR: 0.638, 95% CI: 0.415– 0.981).Conclusion: Weekend CUS was associated with a low risk of metabolic syndrome among Korean adults with sleep restriction.Keywords: sleep recovery, sleep deprivation, metabolic syndrome, insulin sensitivity
