Analysis reveals increased sleep disturbance in shift workers, highlighting demographic risk factors.

To examine how different shift work patterns relate to sleep disturbance and how this relationship is affected by various factors.
Analyzed cross-sectional data from the UK Biobank study
Included 285,175 employed participants aged 40-69
Assessed associations using multivariable logistic regression to adjust for potential confounding factors
14.8% of participants reported sleep disturbance symptoms
Shift workers had higher odds of sleep disturbance compared to non-shift workers
Odds ratios indicated greater risk for those working night shifts (OR 1.50 for always night shifts)
Age, ethnicity, and smoking status modified the association between shift work and sleep disturbance

Li et al. (2026) studied this question.
