Abstract

Keenoa™ is a novel Canadian diet application (app) currently used by Canadian dietitians to collect diet-related data from clients. The goal of this study was to evaluate Keenoa™ based on user feedback and compare it to a conventional pen and paper method. One hundred and two participants were recruited and randomly assigned to record their diets using this application for 3 nonconsecutive days. Following this, participants were invited to complete an online “exit” survey. Seventy-two subjects responded, with 50 completing an open-ended question asking for general feedback about the app. Data were reviewed and 3 main themes emerged: strengths, challenges, and future recommendations. Strengths associated with the app consisted of picture recognition software, the additional commentary feature, and the overall pleasant data collection process. Challenges that were identified included inconsistencies with the barcode scanning features, the limited food database, time to enter food details, and software issues. Future recommendations included using a larger food database, pairing dietary intake with physical activity monitoring, and having accessible nutritional data. Despite these limitations, participants preferred using mobile apps to record diet compared with traditional written food diaries.

Résumé

Keenoa™ est une nouvelle application canadienne sur l’alimentation que des diététistes canadiens utilisent pour recueillir des données auprès de leurs clients sur leur alimentation. L’objectif de cette étude était d’évaluer Keenoa™ sur la base de commentaires d’utilisateurs et de la comparer à une méthode traditionnelle avec crayon et papier. Cent deux participants recrutés et assignés au hasard ont été invités à consigner leurs prises alimentaires à l’aide de cette application pendant trois jours non consécutifs. Ensuite, ils ont été invités à répondre à un sondage en ligne. Soixante-douze sujets ont répondu, et 50 ont répondu à une question ouverte réservée aux commentaires généraux sur l’application. Les données ont été examinées, et trois thèmes principaux sont ressortis : forces, défis et recommandations pour l’avenir. Les forces de l’application concernaient le logiciel de reconnaissance d’image, la fonction permettant d’ajouter des commentaires et le processus de collecte de données globalement agréable. Les défis soulevés incluaient les incohérences du lecteur de codes-barres, la base de données d’aliments limitée, le temps nécessaire à la saisie des détails sur les aliments et des problèmes de logiciel. Parmi les recommandations pour l’avenir, citons l’utilisation d’une base de données sur les aliments plus vaste, le jumelage de l’apport alimentaire au suivi de l’activité physique et l’accès à des données nutritionnelles. Malgré ces limites, les participants ont préféré utiliser des applications mobiles pour consigner leurs prises alimentaires plutôt que de tenir un journal alimentaire traditionnel par écrit.
