Objective:
This study aimed to explore how occupational physical activity (OPA) and leisure-time physical activity (LTPA) interact with nurses assigned to different roles (ie, registered and assistants).
Methods:
Twenty-two professional nurses were monitored for 7 days, using a wearable accelerometer. Based on raw data, physical activity (PA) was classified as sedentary behavior, and light-, moderate-, and vigorous-intensity PA.
Results:
In comparison with registered nurses, certified nursing assistants spent less time in sedentary behavior (29% vs 53%) and more time in moderate-intensity PA (20% vs 8.8%) and vigorous-intensity PA (20.5% vs 9.1%) during working shifts. In contrast, LTPA levels were similar across the groups (~30%). Associations between OPA and LTPA differed by role.
Conclusion:
Among nurses, job roles shape the OPA-LTPA relationship. Measuring PA provides essential evidence for designing workplace interventions that promote balanced activity and recovery.

The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.
