Link between rotating night shifts and metabolic syndrome in Korean workers: comparing 8-hour and 12-hour shifts

A two-shift work schedule is associated with a 1.72 times higher odds of metabolic syndrome compared to other schedules.

• The study included data from 2,090 workers evaluated for metabolic syndrome in 2010.
• Participants were categorized into daytime, three-shift, and two-shift workers.
• Two-shift rotation workers showed a positive association with metabolic syndrome (odds ratio of 1.58).
• In rotating night-shift workers, the odds ratio increased to 1.72 after accounting for additional factors such as sleep disturbances.
• The findings suggest that the risk of metabolic syndrome varies with different shift work schedules.
