BACKGROUND: The Health Wrist Watch (HW; Seiko Epson Co., Ltd., Suwa, Japan) was developed to monitor and evaluate lifestyles as measured by heart rate (HR) variability, acceleration, and calculation of energy expenditure (EE). In this study, we verified the accuracy of the HW by comparing EE in 30 elderly people obtained from the HWwith that from a precise metabolizer (VO 2000®; Medical Graphics, Milan, Italy). Furthermore, the relationship in 33 elderly people between the risk of metabolic syndrome, results determined by a medical examination, and the lifestyle index measured by the HW were compared.
METHODS: To investigate validity, controlled rest, mental arithmetic, and walking were measured with the HW and VO2000 in elderly men. In the application study, activity times (sleep, mental activity, mental stress, physical activity, exercise) and EE were measured with the HW. The HW data were compared with medical examination results regarding the risk of lifestyle-related disease.
RESULTS: EE measured by the HW correlated significantly with VO2000 measurements for mental and physical activity performed high significant (r=0.89, P<0.01). Deep sleep time as measured by the HW correlated significantly (P<0.05) with body weight (r=-0.44), BMI (-0.41), abdominal circumference (-0.49), T-cho (-0.37), LDL-cho (-0.40), and lower limb muscle strength (0.42). Physical activity times correlated significantly with brachial-ankle pulse wave velocity (-0.51) (P<0.05).
CONCLUSIONS: The HW could easily evaluate EE during mental and physical activity in elderly men. Physical activity times, EE, and sleep times as measured by the HW correlated significantly with the risk of metabolic syndrome and nursing care factors.
