Development of treatment system for eating disorders using personal digital assistants

本研究的目的是为开发一种新的饮食失调治疗系统做准备，其结果如下。为了研究多动症，一个重要的临床症状，患者和健康对照被要求佩戴加速度计，以评估客观的身体活动。我们发现，体力活动的昼夜节律的相位显着前移神经性厌食症（AN）限制型比健康对照组，而体力活动消耗的能量是较小的AN患者比对照组。此外，我们开发了计算机化的生态瞬时评估（EMA）系统，用于评估和记录症状，行为和食物摄入量，这将能够应用于自然环境中的干预。

The results of the present study, the aim of which was to prepare for developing a new treatment system for eating disorders, were as follows. To investigate hyperactivity, one of the important clinical symptoms, patients and healthy controls were asked to wear accelerometers to assess objective physical activity. We found that the phase of the diurnal rhythm of physical activity significantly moved more forward in anorexia nervosa (AN) restricting type than in healthy controls while consumption energy by physical activity was smaller in AN patients than in controls. In addition, we developed computerized ecological momentary assessment (EMA) system for assessing and recording symptoms, behavior, and food intake, which will be able to apply to intervention in natural settings.
