饮食评估在成人中充满了错误[1]，尤其是在儿童中[2，3]。多达50%的儿童报告前一天早餐和午餐的食物24小时饮食回忆有错误[4]，与直接观察消费进行评估。创新技术可以提供更准确的膳食摄入量评估[5]。一种最近可用的创新方法是佩戴在胸部的相机（称为eButton），该相机在一天中以短暂的间隔（2秒至10秒）拍摄佩戴者面前的任何物体的图像[6-10]。食物的图像可以最大限度地减少食物的不准确回忆，但可能有其他限制。这些图像可以被聚类为常见的单个进食事件的图像[9-12]。食物事件图像集群中的一些食物可以自动识别，但大多数必须由观察者识别，通常是营养师[9，10]。可以使用创新的数字丝网程序来估计食物图像部分大小[9，10，13-16]。虽然eButton已经在成年人中进行了测试[14-16]，但将其调整为儿童使用需要了解其接受程度和程序使用。对儿童使用eButton进行了两项形成性研究。
Dietary assessment is fraught with error among adults [1] and especially among children [2, 3]. As much as 50% of child reported 24 hour dietary recall of foods for the previous day’s breakfast and lunch had errors [4] as assessed against direct observation of consumption. Innovative technology may provide more accurate assessments of dietary intake [5]. One recently available innovative method is a camera worn on the chest (called an eButton) that takes images of whatever is in front of the wearer at brief intervals (2 sec to 10 sec) throughout the day [6–10]. Images of foods could minimize inaccurate recall of foods, but may have other limitations. These images can be clustered into images of a common single eating event [9–12]. Some of the foods in the food event image clusters can be automatically identified, but most must be identified by observers, usually dietitians [9, 10]. Food image portion size can be estimated using an innovative digital wire mesh procedure [9, 10, 13–16]. While the eButton has been tested among adults [14–16], adapting it for use by children requires understanding of its acceptance and procedural use. Two formative studies were conducted for using the eButton with children.
