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

What this Trial Is About

Physically inactive nurses with poor sleep quality face a higher risk of developing non-communicable diseases. Nurses are especially vulnerable due to their demanding shift work and heavy workloads, which may prevent them from meeting recommended physical activity levels. This trial evaluates the effects of a behavioral intervention initiated by wearable devices on body composition, physical activity, sleep quality, and stress among nurses working in a hospital setting. The study randomly assigns 120 nurses into two groups. One group receives a 12-week behavioral intervention using wearable devices combined with a LINE app that provides behavior change advice and weekly 15-minute motivational interviewing sessions through an app. The comparison group receives wearable devices for 12 weeks that only monitor physical activity and sleep quality without additional behavioral support. Data collection occurs at baseline, 12 weeks, and 24 weeks follow-up. Participants will be monitored for physical activity and sleep quality using Fitbit wearable devices and applications. Body composition is assessed by bioelectrical impedance analysis, and stress levels are measured by salivary amylase activity. Researchers will track the effects over time and between groups, assess treatment quality, identify barriers to implementation, and evaluate participant satisfaction. The primary outcomes focus on subjective and objective physical activity, measured from enrollment through 24 weeks.
