Effects of Wearable Devices Initiates Behavioral Change Intervention on Body Composition, Physical Activity, Sleep Quality and Stress of Nurses in Hospital Working Place

Background: Physically inactive and poor sleep quality are at increased risk for non-communicable diseases. Nurses were the most vulnerable inactive healthcare personnel who may not meet global physical activity recommendations because of complicated rotation shifts and heavy working loading. Wearable devices initiate behavior intervention combined with smartphone applications could offer new opportunities for social connection by a convenient way for nurses to improve physical activity and sleep quality. Objectives: To evaluate the effects of wearable devices initiate behavioral intervention on body composition, physical activity, sleep quality and stress of nurses in hospital working place. Method: This is a randomized controlled trial that will recruit 120 nurses and randomly assign them into two groups from a hospital working place. The nurses in the intervention group will receive 12-week wearable devices to initiate behavioral intervention. The nurses in the comparison group will only receive 12-week wearable devices monitoring. Data will be collected at baseline and 12-week and 24-week follow-up. The body composition will be measured by bioelectrical impedance analysis (BIA). The physical activity and sleep quality will be monitored by the Fitbit wearable device and application. The mediator parameter of the stress will be measured by salivary amylase activity (SAA). We will control the internal validity to assure the quality of training, treatment fidelity, identify barriers and facilitators of implementation, and assess participants' satisfaction. General estimating equations (GEE) will be applied to examine the effects of time and group interaction.
