Abstract

BACKGROUND

Weight management apps may provide support and management options for individuals with overweight and obesity. Research on the quality of weight management mHealth apps among the Saudi population is insufficient despite frequent use.

OBJECTIVE

The aims of this study were to explore user perceptions of weight management apps, explore reasons for starting and stopping app use, appraise the quality of weight management apps available in the App Store, and compare the features currently available within the app market and those that are most desirable to weight management app users.

METHODS

A web-based survey consisted of 31 open and closed questions about sociodemographic information, general health questions, app use, app user perceptions, and discontinuation of app use. The quality of the weight management apps available on the App Store was assessed using the Mobile App Rating Scale and evidence-based strategies. We also used six sigma evaluations to ensure that the quality measured by the tools consistently meets customer expectations.

RESULTS

Data from the survey were analyzed. Of the respondents, 30.17% (324/1074) had used a weight management app, 18.16% (195/1074) used the apps and stopped, and 51.68% (555/1074) had never used a weight management app. Of apps mentioned, 23 met the inclusion criteria. The overall average Mobile App Rating Scale quality of apps was acceptable; 30% (7/23) received a quality mean score of 4 or higher (out of 5), and 30% (7/23) did not meet the acceptability score of 3 or higher. Evidence-based strategy results showed that feedback was not observed in any of the apps, and motivation strategy was observed in only 1 app. The sigma results of evidence-based strategies reflect that most of the apps fail to pass the mean.

CONCLUSIONS

App users desired a feature that allows them to communicate with a specialist, which is a missing in the available free apps. Despite the large number and accessibility of weight management apps, the quality and features of most are variable. It can be concluded from six sigma results that passing the mean does not ensure that the quality is consistently distributed through all app quality properties and Mobile App Rating Scale and evidence-based strategies do not give developers an indication of the acceptance of their apps by mobile users. This finding stresses the importance of reevaluating the passing criterion, which is ≥50% for designing an effective app.

摘要

背景

体重管理应用程序可为超重和肥胖人群提供支持和管理选项。尽管沙特人口频繁使用，但针对体重管理移动健康应用程序质量的研究还不够充分。

目的

本研究旨在探讨用户对体重管理应用程序的看法，探讨开始和停止使用应用程序的原因，评估 App Store 中可用的体重管理应用程序的质量，并比较当前应用市场中的功能以及对体重管理应用程序用户最理想的功能。

方法

采用基于网络的调查，共包含 31 个关于社会人口统计学信息、一般健康问题、应用程序使用、应用程序用户看法和停止使用应用程序的开放性和封闭性问题。使用移动应用程序评级量表和基于证据的策略评估 App Store 中可用的体重管理应用程序的质量。我们还使用六西格玛评估来确保工具测量的质量始终符合客户的期望。

结果

对调查数据进行了分析。在受访者中，有 30.17%（324/1074）使用过体重管理应用程序，18.16%（195/1074）使用过应用程序后停止使用，51.68%（555/1074）从未使用过体重管理应用程序。在提到的应用程序中，有 23 个符合纳入标准。应用程序的总体平均移动应用程序评级量表质量是可以接受的；有 30%（7/23）的应用程序获得了 4 或更高的质量平均分（满分 5 分），而 30%（7/23）的应用程序未达到 3 或更高的可接受分数。基于证据的策略结果表明，在任何应用程序中都没有观察到反馈，只有 1 个应用程序观察到了激励策略。基于证据的策略的西格玛结果表明，大多数应用程序都未能通过平均值。

结论

应用程序用户希望具有与专家交流的功能，这是可用免费应用程序中所缺少的。尽管有大量且易于访问的体重管理应用程序，但大多数应用程序的质量和功能各不相同。六西格玛结果表明，通过平均值并不能确保质量始终分布在所有应用程序质量属性和移动应用程序评级量表和基于证据的策略中，并且这些策略并不能向开发人员表明移动用户对其应用程序的接受程度。这一发现强调了重新评估通过标准的重要性，即对于设计有效的应用程序，通过标准≥50%。
