Are Middle-Aged and Older Adult Users of Physical Activity Monitoring Systems More Physically Active and at a Lower Risk of Locomotive Syndrome? A Cross-Sectional Web-Based Online Survey.

Background: Physical inactivity is a risk factor for locomotive syndromes and functional limitations in middle-aged and older adults. Therefore, strategies to promote physical activity should be considered. This study investigated whether users of physical activity monitors were more physically active and exhibited a lower risk of locomotive syndrome, compared with non-users.

Methods: We analyzed data from 742 Japanese adults aged 60-79 years. The participants were surveyed for their use of physical activity monitors in their daily lives. We also assessed the prevalence of locomotive syndrome.

Results: We observed significantly higher physical activity levels in users compared with non-users. Moreover, the use of a physical activity monitor was significantly associated with decreased odds of locomotive syndrome (adjusted odds ratio [aOR]=0.48). Significantly lower risk of locomotive syndrome were observed in individuals who had used a monitor for >2 years (aOR=0.42) or had set a personal step goal (aOR=0.32).

Conclusion: Physical activity monitoring may increase engagement in physical activity-associated behavior. Therefore, monitoring could serve as a useful tool to promote physical health in middle-aged and older adults.
