Different Exposure Metrics of Rotating Night-Shift Work and Serum Lipid Profiles Among Steelworkers

Rotating night-shift work for 13 to 20 years is associated with increased total cholesterol levels in steelworkers.

• Night-shift workers with an average of four or more shifts per month showed higher total cholesterol levels compared to day workers.
• The duration of night shifts may lead to increased cholesterol levels through mediating factors such as blood pressure and body mass index.
• Systolic and diastolic blood pressure, along with body mass index, could play a role in the relationship between night shift work and cholesterol levels.
