Effects of Feedback From Self-Monitoring Devices on Lifestyle Changes in Prediabetes Workers: A 3-Month Randomized Controlled Trial
ABSTRACT
Background:
Although lifestyle interventions are useful in prevention and management of diabetes, they can be expensive and time-consuming. There is some evidence for the effectiveness of automated mobile technology for health self-monitoring, however, no studies have used such devices with prediabetes workers.
Objective:
We aimed to examine the effectiveness of a 3-month digital self-monitoring device on glucose levels and health behaviors of prediabetes workers in Japan. The primary outcome was blood glucose levels and the secondary outcomes were changes in health behaviors and BMI.
Methods:
A two-arm randomized controlled trial was conducted with workers from 23 organizations. The intervention group (n=50, data analyzed for n=46) wore an armband activity monitor, a body composition monitor, and a blood pressure monitor for 3 months and received semi-automated weekly email messages tailored to their device data. The control group (n=53, data analyzed for n=48) engaged in no self-monitoring. Messages were developed by a physician and a dietician. Post-intervention changes in blood glucose levels, BMI, and health behaviors were compared between the intervention and control groups using blood tests and device data.
Results:
At the end of 3 months, the intervention group showed significantly lower blood glucose levels (HbA1c [%]: intervention mean 6.4 vs. control mean 6.6; Cohen d=0.7; 95% CI 0.2-1.1; P=.009) and significantly greater motivation to increase their daily exercise than the control group. There were no significant between-group differences in BMI or health behaviors.
Conclusions:
Mobile digital self-monitoring was effective in improving blood glucose levels and motivation to increase daily exercise in prediabetes workers. The use of digital health devices is a cost-effective way of implementing health self-monitoring for large numbers of individuals in the workplace. Clinical Trial: This study is registered with the University Hospital Medical Information Network (UMIN000023651).
