关于膳食摄入量的信息为预防慢性疾病的干预方案提供了一些最有价值的见解。随着对青少年超重问题的日益关注，准确测量饮食的需求变得势在必行。对青少年的评估是有问题的，因为这个群体的饮食模式不规律，他们对记录食物摄入量的热情也不高。我们在青少年中使用定性和定量技术来评估他们对饮食评估方法的偏好。使用技术的饮食评估方法，例如个人数字助理（PDA）或一次性相机，比笔和纸的食物记录更受欢迎。人们强烈倾向于使用结合技术的方法，比如捕捉食物的图像。这表明，对于青少年来说，结合技术的饮食方法可能会提高合作和准确性。当前的计算技术包括更高分辨率的图像、更大的内存容量和更快的处理器，这些使得小型移动设备能够处理以前不可能处理的信息。我们的目标是开发、实施和评估一种移动设备（例如掌上电脑、移动电话）的食物记录，它将转化为青少年每日食物和营养摄入的准确记录。这种移动计算设备将包括数字图像、营养数据库和图像分析，用于识别和量化食物消耗。移动计算设备为收集饮食信息提供了一种独特的工具，减轻了记录保持者的负担。食物的图像可以用多种输入方法进行标记，这些输入方法将物品链接起来进行图像处理和分析，以估计食物的数量。食物被吃掉前后的图像可以估计食物的消耗量。本项目的初步阶段和潜力将会被描述。
Information on dietary intake provides some of the most valuable insights for mounting intervention programmes for the prevention of chronic diseases. With the growing concern about adolescent overweight, the need to accurately measure diet becomes imperative. Assessment among adolescents is problematic as this group has irregular eating patterns and they have less enthusiasm for recording food intake. We used qualitative and quantitative techniques among adolescents to assess their preferences for dietary assessment methods. Dietary assessment methods using technology, for example, a personal digital assistant (PDA) or a disposable camera, were preferred over the pen and paper food record. There was a strong preference for using methods that incorporate technology such as capturing images of food. This suggests that for adolescents, dietary methods that incorporate technology may improve cooperation and accuracy. Current computing technology includes higher resolution images, improved memory capacity and faster processors that allow small mobile devices to process information not previously possible. Our goal is to develop, implement and evaluate a mobile device (for example, PDA, mobile phone) food record that will translate to an accurate account of daily food and nutrient intake among adolescents. This mobile computing device will include digital images, a nutrient database and image analysis for identification and quantification of food consumption. Mobile computing devices provide a unique vehicle for collecting dietary information that reduces the burden on record keepers. Images of food can be marked with a variety of input methods that link the item for image processing and analysis to estimate the amount of food. Images before and after the foods are eaten can estimate the amount of food consumed. The initial stages and potential of this project will be described.
