| Summary: | Background: Physical activity and quality of life (QOL) influence the health status of older
adults. Recently, the use of wearable devices to monitor physical activity has increased.
Objects: This study examined the relationship between the amount of physical activity, measured
using a wearable device, and QOL among older adults.
Methods: In total, 71 older adults (aged ≥ 65 years) were enrolled. The amount of physical
activity was measured using a wearable device with a wrist strap, and daily physical activity
was classified according to intensity (sedentary, light, moderate, or very active). Self-reported
QOL was evaluated using the Short Form 36 (SF-36) questionnaire. Pearson and Spearman
correlation analyses were conducted to analyze parametric and non-parametric variables, respectively.
The relationship between amount of daily physical activity and SF-36 scores was
assessed.
Results: The correlation analyses revealed positive correlations between the amount of moderate-
intensity and very active physical activity (minutes/day) and SF-36 scores (p < 0.05).
Conclusion: Physical activity of at least moderate intensity is associated with better QOL in
older adults. Further studies are required to verify the effects of increased physical activity on
QOL in older adults. |
