背景资料：使用智能手机应用程序（应用程序）来帮助体重管理越来越普遍，但这些应用程序的质量并没有很好地表征。目的：本研究的目的是评估饮食/营养和人体测量跟踪应用程序，这些应用程序基于与行为改变理论一致的特征。方法：对iTunes App Store中健康和健身类别中排名最高的免费应用程序进行了比较性描述性评估。使用预定的纳入/排除标准对健康和健身应用程序（N=200）进行了评价，并根据功能、特性和开发人员描述的共性进行了分类。然后，四名研究人员使用两种工具评估了每个类别中最受欢迎的两个应用程序：一种基于传统行为理论（得分范围：0-100），另一种基于Fogg行为模型（得分范围：0-6）。数据收集和分析发生在2012年11月。结果：符合条件的应用程序（n=23）分为五类：（1）饮食跟踪;（2）健康烹饪;（3）体重/人体测量跟踪;（4）杂货决策;（5）餐厅决策。平均行为理论得分为8.1（SD=4.2）;平均说服技术得分为1.9（SD=1.7）。在这两个尺度上最受欢迎的应用程序是Lose It！结论：所有应用程序在包含基于行为理论的策略方面的总体得分都很低。(C)2013年美国预防医学杂志
Background: The use of smartphone applications (apps) to assist with weight management is increasingly prevalent, but the quality of these apps is not well characterized.Purpose: The goal of the study was to evaluate diet/nutrition and anthropometric tracking apps based on incorporation of features consistent with theories of behavior change.Methods: A comparative, descriptive assessment was conducted of the top-rated free apps in the Health and Fitness category available in the iTunes App Store. Health and Fitness apps (N=200) were evaluated using predetermined inclusion/exclusion criteria and categorized based on commonality in functionality, features, and developer description. Four researchers then evaluated the two most popular apps in each category using two instruments: one based on traditional behavioral theory (score range: 0-100) and the other on the Fogg Behavioral Model (score range: 0-6). Data collection and analysis occurred in November 2012.Results: Eligible apps (n=23) were divided into five categories: (1) diet tracking; (2) healthy cooking; (3) weight/anthropometric tracking; (4) grocery decision making; and (5) restaurant decision making. The mean behavioral theory score was 8.1 (SD=4.2); the mean persuasive technology score was 1.9 (SD=1.7). The top-rated app on both scales was Lose It! by Fitnow Inc.Conclusions: All apps received low overall scores for inclusion of behavioral theory-based strategies.
