Brief Summary

1. In the first month of the trial, the frequency of the PHR recording was 64.9% in Maintenance stage, 70.0% in Action stage, 73.3% in Preparing stage, 74.1% in Contemplation stage, and 97.6% in Precontemplation stage. However, in the third month, those frequency fell down to 43.3%, 66.7%, 49.3%, 51.9%, and 37.3%, respectively. 2. At the end of the trial, 70% level of those who were at first in the Contemplation and Precontemplation stage improved their behavior modification stage. However, among those who were at first in the other stages, the stage improvement percentages were all under 50%. 3. According to the opinions of the questionnaire respondents, the usage of the PHR service turned out to be low due to our originally developed integration indices for PHR recording. 4. With regard to the sleep duration time, the correlation coefficient between the time by PHR and that by another accelerometer was -0.32, using the data from 7 nights in 3 subjects. Also, the correlation ratio between the time from PHR and that from the questionnaire was 0.27. 5. The result using the multiple linear regression analysis showed that, compared to those in the Pre-contemplation stage, those in the Contemplation, Preparation, Action, and Maintenance stage took more daily average steps by 825.9, 658.0, 3011.0, and 2412.4, respectively, at point estimate. However, neither of them were statistically significant except for Maintenance stage (p=0.02). Therefore, the effect of our service was not efficient for those whom we intended to change their behavior.
