Analysis of the association between health-related and work-related factors among workers and metabolic syndrome using data from the Korean National Health and Nutrition Examination Survey (2016)

ABSTRACT

BACKGROUND/OBJECTIVE: This study analyzed health-related factors for metabolic syndrome (Mets) among workers in South Korea. SUBJECTS/METHODS: This analysis included 4,666 adults aged 19–64 years to analyzed health-related risk factors for Mets from the Korean National Health and Nutrition Examination Survey (2016). The sociodemographic, working, health-related, and biochemical characteristics were presented as percentages (%) by chi-square tests. Multiple logistic regression analysis was performed to analyze the 95% confidence intervals (CIs) and associations between health-related factors characteristic of workers and the odds ratios of Mets. RESULTS: An increased prevalence of Mets was associated with male day workers compared to male shift workers (1.726-fold increase, 95% CI 1.077–2.765), and with ≥ 8 hrs/day sleep duration compared to < 6 hrs/day sleep duration in female workers (2.133-fold, 95% CI 1.041–4.368). In addition, reduced odds of high Mets were associated with male workers consumed of breakfast 5–7 times/wk compared to those consumed < 1 time/wk (0.593-fold decrease, 95% CI 0.372–0.944). CONCLUSIONS: Health-related factors (sleep duration, frequency of breakfast) and working type in Korean workers may affect the prevalence of Mets.
