Understanding how adherence to dietary self-monitoring with apps has been defined is a first step toward examining the relationship between adherence and weight loss. The purpose of this review was to explore how adherence to dietary self-monitoring has been defined in the empirical literature that addresses weight loss app use by overweight and obese adults. The integrative review method and the preferred reporting items for systematic reviews and meta-analyses guided this review. Scientific databases (n=5) were searched, which yielded 29 studies. Studies were screened, evaluated for data quality, and then analyzed according to the constant comparison method. Most studies were weak to moderate quality. Results indicated that adherence was operationally defined in two ways. Adherence was defined as either adherent or nonadherent based on the completion of recording a minimum amount of calorie intake or a calorie amount within a specific range of calories. Another way that adherence was defined was the frequency of dietary self-monitoring, which included the frequency of dietary intake recording, interaction with apps, and the timing of recording. Some studies defined adherence in both ways. Most included studies lacked diversity in study samples. Until a consensus is reached, it may be prudent to study multiple indicators of adherence to dietary self-monitoring using apps, and their respective relationships with weight loss. Studies are needed that address the type and degree of adherence to dietary self-monitoring with an app that is associated with weight loss in diverse populations.

使用移动应用程序定义对饮食自我监测的依从性：叙事评论

了解如何通过应用程序进行饮食自我监测是检查坚持与减肥之间关系的第一步。本综述的目的是探讨如何在解决超重和肥胖成年人使用减肥应用程序的经验文献中定义坚持饮食自我监测。系统评价和荟萃分析的综合评价方法和首选报告项目指导了本评价。检索了科学数据库 (n=5)，获得了 29 项研究。筛选研究，评估数据质量，然后根据恒定比较方法进行分析。大多数研究质量弱到中等。结果表明，依从性以两种方式在操作上定义。依从性被定义为依从性或非依从性，基于完成记录最低卡路里摄入量或特定卡路里范围内的卡路里量。另一种定义依从性的方式是饮食自我监测的频率，包括饮食摄入记录的频率、与应用程序的交互以及记录的时间。一些研究以两种方式定义了依从性。大多数纳入的研究缺乏研究样本的多样性。在达成共识之前，谨慎使用应用程序研究坚持饮食自我监测的多个指标，以及它们各自与减肥的关系。需要研究通过与不同人群的体重减轻相关的应用程序来解决坚持饮食自我监测的类型和程度。
