背景：技术，特别是通过移动设备访问互联网，已经永远改变了我们与他人交往的方式以及我们在日常生活中的行为方式。近年来，人们进行了研究来分析通过移动电话在健康领域采取的不同行动的有效性：电话、短信服务（SMS）、远程医疗以及最近使用的推送通知。我们继续探索增加用户与移动应用程序交互的方法，这是移动医疗领域悬而未决的主题之一。通过分析临床试验期间受试者产生的数据，我们能够提取行为模式，并根据这些模式设计有效的减肥方案。 目的：提出一项临床试验，目的是（1）评估推送通知在旨在通过饮食程序改善超重或肥胖成年女性身体成分的干预措施中的功效，以及（2）根据推送通知和规定的体力活动（PA）分析身体成分的演变。方法：进行了一项双臂随机对照试验。样本量为 117 名成年肥胖女性，每周进行一次 30 分钟的面对面咨询，持续 6 个月。所有患者都配备了为本研究设计的应用程序和计步器。对照组无法使用与在家自我监测体重、游戏化或 PA 处方相关的功能。干预组成员的目标是通过独家访问应用程序的特定功能和推送通知来实现一定程度的饮食和 PA 合规性。为所有患者规定了相同的饮食。针对对照组和干预组研究了三种可能的 PA 情景：轻度体力活动 (LPA)、中度体力活动 (MPA) 和剧烈体力活动 (IPA)。对于三个或更多平均值的分析，进行重复平均值的方差分析 (ANOVA)，以评估干预在基线以及第 3 个月和第 6 个月时的效果。结果：在干预期间收到通知增加了体脂减少（干预组平均值为 -12.9% [SD 6.7]，而对照组平均值为 -7.0% [SD 5.7]；P
Background: Technology-in particular, access to the Internet from a mobile device-has forever changed the way we relate to others and how we behave in our daily life settings. In recent years, studies have been carried out to analyze the effectiveness of different actions via mobile phone in the field of health: telephone calls, short message service (SMS), telemedicine, and, more recently, the use of push notifications. We have continued to explore ways to increase user interaction with mobile apps, one of the pending subjects in the area of mHealth. By analyzing the data produced by subjects during a clinical trial, we were able to extract behavior patterns and, according to them, design effective protocols in weight loss programs.Objective: A clinical trial was proposed to (1) evaluate the efficacy of push notifications in an intervention aimed at improving the body composition of adult women who are overweight or obese, through a dietary procedure, and (2) analyze the evolution of body composition based on push notifications and prescribed physical activity (PA).Methods: A two-arm randomized controlled trial was carried out. A sample size of 117 adult obese women attended a face-to-face, 30-minute consultation once a week for 6 months. All patients were supplied with an app designed for this study and a pedometer. The control group did not have access to functionalities related to the self-monitoring of weight at home, gamification, or prescription of PA. The intervention group members were assigned objectives to achieve a degree of compliance with diet and PA through exclusive access to specific functionalities of the app and push notifications. The same diet was prescribed for all patients. Three possible PA scenarios were studied for both the control and intervention groups: light physical activity (LPA), moderate physical activity (MPA), and intense physical activity (IPA). For the analysis of three or more means, the analysis of variance (ANOVA) of repeated means was performed to evaluate the effects of the intervention at baseline and at 3 and 6 months.Results: Receiving notifications during the intervention increased body fat loss (mean -12.9% [SD 6.7] in the intervention group vs mean -7.0% [SD 5.7] in the control group; P
