Given the increasing social and economic burden of chronic disease and the need for efficient approaches to prevent and treat chronic disease, emphasis on the use of information and communication technology (ICT)-based health care has emerged. We aimed to test the feasibility of a mobile application, Diet-A, and examine whether Diet-A could be used to monitor dietary intake among adolescents. In a three-month pre-post intervention study, 9 male and 24 female high school students aged 16-18 years consented and participated in this study. Participants were instructed to record all foods and beverages consumed using voice or text mode input. Nutrient intake was measured using 24-h recalls pre- and post-intervention. We compared nutrient intake data assessed by Diet-A application with those assessed by 24-h recalls. Participants tended to underreport intakes of nutrients compared to those assessed by two 24-h recalls. There were significant decreases in sodium ( = 0.04) and calcium ( = 0.03) intake between pre- and post-intervention. Of participants who completed questionnaires of feasibility ( = 24), 61.9% reported that they were satisfied using the application to monitor their food intake, and 47.7% liked getting personal information about their dietary intake from the application. However, more than 70% of participants answered that it was burdensome to use the application or that they had trouble remembering to record their food intake. The mobile application Diet-A offers the opportunity to monitor dietary intake through real-time feedback. However, use of Diet-A may not provide accurate information on the food intake of adolescents, partly because of the recording burden.
鉴于慢性病带来的社会和经济负担日益加重，以及预防和治疗慢性病需要高效方法，基于信息通信技术（ICT）的医疗保健的应用受到了更多关注。我们旨在测试一款名为Diet-A的移动应用程序的可行性，并研究Diet-A是否可用于监测青少年的饮食摄入量。在一项为期三个月的干预前后研究中，9名16 - 18岁的男性和24名女性高中生同意并参与了本研究。参与者被要求使用语音或文本模式输入记录所摄入的所有食物和饮料。在干预前后通过24小时回顾法测量营养摄入量。我们将通过Diet-A应用程序评估的营养摄入数据与通过24小时回顾法评估的数据进行了比较。与通过两次24小时回顾法评估的结果相比，参与者往往会少报营养摄入量。干预前后钠（P = 0.04）和钙（P = 0.03）的摄入量有显著下降。在完成可行性问卷的参与者（n = 24）中，61.9%的人表示对使用该应用程序监测食物摄入量感到满意，47.7%的人喜欢从该应用程序中获取有关其饮食摄入量的个人信息。然而，超过70%的参与者回答说使用该应用程序很麻烦，或者他们难以记住记录食物摄入量。移动应用程序Diet-A提供了通过实时反馈监测饮食摄入量的机会。然而，使用Diet-A可能无法提供关于青少年食物摄入量的准确信息，部分原因在于记录负担。
