Due to global advances in technology, image-based food record methods have emerged as an alternative to traditional assessment methods. The use of image-based food records in low and lower-middle income countries such as Tanzania is limited, with countries still using traditional methods. The current study aimed to determine the feasibility of using a new voice and image-based dietary assessment system (VISIDA) in Dar es Salaam, Tanzania. This mixed-method study recruited 18 nutritionists as participants who collected image-based records of food and drinks they consumed using the VISIDA smartphone app. Participants viewed an online demonstration of the VISIDA web platform and the analysis process for intake data collected using the VISIDA app. Then, participants completed an online survey and were interviewed about the VISIDA app and web platform for food and nutrient intake analysis. The method was reported as being acceptable and was found to be easy to use, although technical challenges were experienced by some participants. Most participants indicated a willingness to use the VISIDA app again for one week or longer and were interested in using the VISIDA system in their current role. Participants acknowledged that the VISIDA web platform would simplify some aspects of their current job. Image-based food records could potentially be used in Tanzania to improve the assessment of dietary intake by nutritionists in urban areas. Participants recommended adding sound-on notifications, using the VISIDA app in both Apple and Android phones, enabling installation from the app store, and improving the quality of the fiducial markers.
由于全球技术的进步，基于图像的食物记录方法已经成为传统评估方法的替代方法。在坦桑尼亚等低收入和中低收入国家，基于图像的食物记录的使用受到限制，这些国家仍在使用传统方法。本研究旨在确定在坦桑尼亚达累斯萨拉姆使用新的语音和基于图像的饮食评估系统（VISIDA）的可行性。这项混合方法研究招募了 18 名营养师作为参与者，他们使用 VISIDA 智能手机应用程序记录他们所消耗的食物和饮料的图像记录。参与者观看了 VISIDA 网络平台和使用 VISIDA 应用程序收集的摄入数据的分析过程的在线演示。然后，参与者完成了一项在线调查，并就 VISIDA 应用程序和网络平台进行了关于食物和营养素摄入分析的访谈。该方法被报告为可接受的，并且被发现易于使用，尽管一些参与者遇到了技术挑战。大多数参与者表示愿意再次使用 VISIDA 应用程序一周或更长时间，并且有兴趣在当前角色中使用 VISIDA 系统。参与者承认 VISIDA 网络平台将简化他们当前工作的某些方面。基于图像的食物记录有可能在坦桑尼亚被用来改善城市地区营养师对饮食摄入的评估。参与者建议添加声音通知、在苹果和安卓手机上使用 VISIDA 应用程序、启用从应用商店安装以及提高基准标记的质量。
