在回溯性自我报告膳食评估中，关于哪些食物和膳食通常被漏报的客观信息很少。自动可穿戴式摄像头记录了自由生活环境中的饮食行为，并允许探索漏报的背景。作为一项验证图像辅助饮食评估的研究的一部分，40名参与者在三次图像辅助24小时饮食回忆前几天佩戴了可穿戴相机。食物和膳食通常被漏报，并对漏报的环境和社会背景进行了评估。最常发生的漏报事件是下午小吃(75/265份)、晚餐(54/265份)和早餐(44/265份)。在下午的零食中，零食最常被漏报，而调味品在早餐时最常被漏报。没有观察到报告不足的社会或环境背景的明确模式。在回顾饮食评估期间，可穿戴式摄像头可以识别特定食物可能被漏报的时间。在饮食评估期间，发现有问题的食物和膳食可以给予额外的关注。
Little objective information exists regarding which foods and meals are typically under-reported during retrospective self-reported dietary assessments. Automated wearable cameras record dietary behaviours in free-living settings and allow the context of under-reporting to be explored. As part of a study to validate image-assisted dietary assessment, 40 participants wore a wearable camera on days before three image-assisted 24-h dietary recalls. The foods and meals were typically under-reported, and the environmental and social contexts of under-reporting were assessed. Under-reporting occurred most frequently during afternoon snacks (75/265 foods), dinner (54/265 foods) and breakfast (44/265 foods). Snack foods were most frequently unreported during afternoon snacks, and condiments were most frequently under-reported at breakfasts. No clear pattern of social or environmental contexts for under-reporting was observed. Wearable cameras can identify when specific foods are likely to be under-reported during retrospective dietary assessments. Problematic foods and meals identified could be given additional attention during dietary assessments.
