Association between rotating night shift work and carotid atherosclerosis among Chinese steelworkers: a cross-sectional survey

The prevalence of carotid plaque in the study population was 29.9%.

• Significantly increased odds of carotid plaque were found among male shift workers compared to day workers, particularly in those with longer durations of night shifts.
• In the third quartile of night shift duration, the odds ratio for carotid plaque was 1.91, indicating a higher likelihood of plaque development.
• In the fourth quartile, the odds ratio remained elevated at 1.69, suggesting a continued association with longer night shift exposure.
• Positive associations between night shift exposure metrics and both the odds of carotid plaque and carotid plaque scores were identified using statistical modeling.
• No significant association was observed between night shift work and carotid plaque in female workers.
