Purpose: The prevalence of metabolic syndrome (MetS), a cluster of metabolic abnormalities has rapidly increased in Korea. Sleep may play a role in determining its prevalence. However, the relationships between MetS and the duration and quality of sleep are not yet clear. This study aimed to examine the associations between the duration and quality of sleep and the prevalence of MetS.
Methods: Study participants included 348 Korean blue-collar workers employed by six small-sized companies in Korea. The data were collected using an interviewer-administered questionnaire, and logistic regression analysis was conducted to estimate the effects of the factors related to MetS.
Results: The multiple logistic regression analysis revealed that the independent factors that contributed to the prevalence of MetS were being male (adjusted odds ratio [aOR]=4.87, 95% confidence interval [CI]=1.58~15.0) and lower sleep quality (aOR=5.12, 95% CI=1.90~14.30). Sleep duration was related to the prevalence of some MetS components, but it was not associated with MetS prevalence.
Conclusion: Sleep quality was negatively associated with MetS prevalence when covariates, such as sleep duration, were controlled. When developing a MetS risk- reduction program, focus should be given to sleep quality as well as sleep duration in an intervention for Korean blue-collar workers.
