Latent Class Analysis of Shift Work Patterns Among Nurses and Its Impact on Anxiety-Depression Comorbidity: A Multicenter Cross-Sectional Study.

Three latent classes were identified among 2791 shift nurses: Class 1: high-frequency, high-seniority group ( N = 441, 15.80%); Class 2: low-frequency, low-seniority group ( N = 835, 29.92%); Class 3: low-frequency, high-seniority group ( N = 1515, 54.28%).

Moreover, Class 1 had the highest risk of these conditions in both unadjusted and adjusted models.

Sleep quality had no significant modifying effect.
