We conducted a systematic review to determine if the use of nutrition apps resulted in improved outcomes, including knowledge and behavior, among healthy adults. Using app(s), cellular phone, iPads, mobile phone, mobile telephone, smart phone, mobile and mHealth as search terms with diet, food and nutrition as qualifiers we searched PubMed, CINAHL (January 2008-October 2013) and Web of Science (January 2008-January 2014). Inclusion criteria were peer-reviewed randomized controlled trials, non-controlled trials, and cohort studies published in English that used apps to increase nutrition knowledge or improve behavior related to nutrition. Studies that were descriptive, did not include apps, focused on app development, app satisfaction app feasibility, text messaging, or digital photography were excluded. We evaluated article quality using the Academy of Nutrition and Dietetics Evidence Analysis Manual. Data was extracted for knowledge, behavior and weight change. Our initial search identified 12,010 titles from PubMed, 260 from CINAHL and 4762 from Web of Science; of these, only four articles met all search criteria. Positive quality ratings were given to three articles; only one reported knowledge outcomes (non-significant). All four articles evaluated weight loss and suggested an advantage to using nutrition apps. Behavioral changes in reviewed studies included increased adherence to diet monitoring (p < 0.001) and decreased effort to continue diet without app (p = 0.024). Few studies, however, have explored the use of nutrition apps as supportive educational interventions. Most apps focus on weight loss with inconsistent outcomes. We conclude that using apps for education needs additional research which includes behavior theory within the app and improved study design.
我们进行了一项系统综述，以确定使用营养应用程序是否能使健康成年人在知识和行为等方面取得更好的结果。我们以应用程序、手机、iPad、移动电话、智能手机、移动设备和移动健康为搜索词，以饮食、食物和营养为限定词，检索了PubMed、CINAHL（2008年1月至2013年10月）和Web of Science（2008年1月至2014年1月）。纳入标准为以英文发表的同行评审随机对照试验、非对照试验和队列研究，这些研究使用应用程序来增加营养知识或改善与营养相关的行为。描述性研究、未包括应用程序的研究、专注于应用程序开发、应用程序满意度、应用程序可行性、短信或数码摄影的研究均被排除。我们使用营养与饮食学会证据分析手册评估文章质量。提取了有关知识、行为和体重变化的数据。我们的初步检索从PubMed中识别出12010个标题，从CINAHL中识别出260个，从Web of Science中识别出4762个；其中只有四篇文章符合所有搜索标准。三篇文章获得了积极的质量评级；只有一篇报告了知识结果（无显著性）。所有四篇文章都评估了减肥情况，并表明使用营养应用程序有优势。综述研究中的行为变化包括饮食监测依从性增加（p < 0.001）以及没有应用程序时继续节食的努力减少（p = 0.024）。然而，很少有研究探讨将营养应用程序用作支持性教育干预措施。大多数应用程序专注于减肥，结果并不一致。我们得出结论，将应用程序用于教育需要更多研究，包括在应用程序中纳入行为理论并改进研究设计。
