Shift worked, quality of sleep, and elevated body mass index in pediatric nurses.

Using the Neuman Systems Model framework, the relationship between shift worked, quality of sleep, and body mass index (BMI) was explored in nurses working at least 8 hours per shift on units providing 24-hour care at a Magnet recognized, Midwestern free-standing pediatric hospital. Electronic surveys collected demographic data and the Pittsburgh Quality of Sleep Index (PSQI) measured sleep quality. Sleep quality was not significantly correlated to elevated BMI >30.
