A study on improving life-related diseases by real-time reinforcement of desirable behaviors

我们一直采用一种实时报告体力活动的系统，包括使用手机发送“奖励电子邮件”。在这项研究中，我们研究了在完成目标体力活动时发送奖励电子邮件的方式。12名患者(患有糖尿病或肥胖，或两者兼有)入选，每天测量步数，持续8周。在S发送奖励邮件的频率在后四周减少的一组中，每天的步数保持不变。S目标量在后4周提高20%的另一组，每日步数没有增加，而是保持不变。然而，无论在这些时间段内发送奖励邮件的方式如何，都保持了体力活动，需要进行更长时间的检查才能确认这一结果。

We have been adopting a real-time reporting system of physical activity including" reward e-mail" using a mobile phone. In this study, we examined the ways of sending reward e-mail at the time of achieving a target amount of physical activity. Twelve patients(with diabetes mellitus, or obesity, or both) were enrolled and daily step counts were measured for eight weeks. In one group who' s frequency of sending reward mails were reduced in latter four weeks, daily step counts were maintained. In the other group who' s target amount was raised 20% in latter four weeks, daily step counts were not increased, but maintained. However physical activity was maintained irrespective of the way of sending reward mails in these periods, a longer examination is needed for confirmation of this result.
