Does Weekend Catch-up Sleep Affect High-Sensitivity C-Reactive Protein Levels Among Korean Workers?: A Cross-Sectional Study Using KNHANES.

OBJECTIVE
We sought to determine whether weekend catch-up sleep (CUS) influenced serum high-sensitivity C-reactive protein (hs-CRP) levels in workers.


METHODS
We analyzed the Korean National Health and Nutrition Examination Survey (2016) data from 3304 workers. Univariate and multivariate logistic regression analyses were used to calculate odds ratios and 95% confidence intervals based on serum hs-CRP cut-off values of 1.0 and 3.0 mg/L, respectively.


RESULTS
We found that at least 1-hour and less than 2 hours of weekend CUS reduced the risk of elevated hs-CRP levels (odds ratio 0.80, 95% confidence interval 0.64 to 0.99) in multivariate logistic regression analysis.


CONCLUSION
CUS may reduce serum hs-CRP levels in workers, thereby reducing the risk of cardiovascular disease.
