手機飲食紀錄應用程式對健康飲食和體重控制之成效
摘要
Background: Diet education and self-monitoring are regarded as essential components of weight reduction programs. Technology-assisted methods with mobile apps for diet monitoring purposes have been used increasingly common. Our study evaluates the effectiveness of an easy-to-use diet monitoring app in an urban community setting. Methods: We developed a weight reduction software program for mobile phone. The DIET-STAR app educated participants on the concept of five food categories and eating three grids a day for each food category. The program provided online diet education, timely feedbacks and healthy diet scores trend over a period of time. Participants were recruited during the community health promotion events. A total of 191 participants completed the input data for this preliminary analysis. Results: Most participants did not have enough daily vegetables and fruits intake. However, their healthy diet scores improved from a mean score of 55.1±22.3 to 62.9±22.8. Mean weight difference was -0.7 kg (range: -5.2-3.0 kg) in follow-up period. Number of recording days was positively associated with weight reduction. Mean weight reduction was 1.6±1.4 kg in the group with more than 14 days of recording, and 0.2±0.9 kg in the group with less than 14 days of recording. Participants with better adherence had higher improvement of healthy diet score (OR=11.5, 95% CI: 4.74-29.9). Conclusions: This DIET-STAR app can be used to help monitor one's diet and weight, allowing users to maintain healthy eating habits and ideal weight management.

目的：減重計劃中飲食指導和每日飲食記錄是重要的組成。使用手機應用程式進行飲食自我管理的技術輔助方法越來越普遍。本研究評估一易於使用的應用程式在城市社區環境中的有效性。方法：我們開發一款手機減重應用程式─五角減重法（DIET-STAR）向參與者介紹五種食物類別以及每種食物類別每天吃三格的概念。該計劃提供線上飲食教育與及時迴饋，並揭示一段時間內健康的飲食分數趨勢與體重變化。在社區健康活動期間招募參加者，共有191名參與者完成輸入數據，進入本研究。結果：大多數參與者沒有足夠的日常蔬菜和水果攝取量。然而，在飲食指導之後健康飲食評分從平均55.1±22.3分提高到62.9±22.8分，平均體重差-0.7kg（範圍：－5.2－3.0kg）。記錄天數與體重減輕及健康飲食評分進步狀態呈正相關，記錄超過14天個案平均體重減輕為1.6±1.4kg，記錄少於14天個案體重減輕為0.2±0.9kg。結論：DIET-STAR應用程序可用於幫助自我監測飲食和體重，讓使用者保持健康的飲食習慣和理想的體重管理。
