Background: Nurses in hospitals work a variety of shifts, and the incidences of sleep disorders and stress patterns were compared in nurses working different shifts.
Methods: Structured questionnaires were used to categorize nurses according to their shifts (daytime nurses, shift-work nurses, or nighttime fixed nurses). The demographic distributions, sleep disorders, and stress patterns in each group were compared.
Results: The nurses’ scores on the General Sleep Disturbance Scale (GSDS) and Global Assessment of Recent Stress were similar. The GSDS sleep scores decreased with aging. Night nurses (fixed and rotating) had more sleep disorders than day nurses did. However, the sleep disturbances were not related to the number of night shifts performed. In each group, the sleep disorders were closely related to sleep maintenance and quality, regardless of the total amount of sleep, and the disorders affected their performance. The responders who were aware of their sleep disorders were reluctant to use sleep aids.
Conclusion: Rotating and night shifts work against the body’s natural rhythms and cause sleep disorders. Nurses with fixed night shifts had similar sleep disorder patterns as nurses with rotating shifts.
