How shift work schedules relate to sleep quality in Chinese workers

Rotating shift workers exhibited higher risks of sleep disturbance compared to fixed day-shift workers.

• Two- and three-shift workers had an odds ratio (OR) of 1.37 and 2.19 for sleep disturbance, respectively, compared to fixed day-shift workers.
• The risk of sleep disturbance was particularly elevated among two- or three-shift workers working more than 8 hours a day or more than 5 days a week.
• Three-shift workers reported both light and heavy physical effort at work and had a higher likelihood of sleep disturbance.
• Rotating shift workers experienced poorer sleep quality than fixed night-shift workers, with ORs of 1.84 and 2.94, respectively.
• Fixed work rhythms may be associated with better sleep quality.
