mHealth中的“m”通常被认为是在旅途中接收健康信息和监控行为的能力。人们实际上是如何使用移动的与传统的访问方法，以及访问方法是否影响参与和健康结果，目前知之甚少。本研究检查了两种移动的减肥干预措施（数字化减重（POD）和移动的POD（mPOD））的3个月结局，其中要求参与者拥有移动终端以进入研究并通过播客接收减肥信息。只有两项研究中随机接受相同理论播客（TBP）的参与者才被用于本分析。在POD中，41名参与者被随机分配到TBP条件下（37名参与者被随机分配到未纳入本分析的对照组）。在mPOD中，49名参与者被随机分配到TBP组（n=49），47名参与者被随机分配到TBP+移动的组（一种自我监测应用程序和Twitter应用程序，用于社会支持）。本研究的目的是检查参与者如何访问研究组件，并检查设备类型如何影响参与和减肥。综合检查两项研究的数据，尽管采用了移动的交付方法，但58%的参与者报告使用非移动的设备访问大多数播客（台式电脑），76%的人主要在家中或工作场所访问播客，62%的人主要是非移动的（例如，坐在工作时）听。检查mPOD的客观下载数据，49%的下载（2889/5944）来自非移动的交付方法，而不是移动的平台（3055/5944）。3个月时，55%的Twitter帖子来自网站（n=665个帖子），而移动的应用程序（n=540; 45%）。通过设备收听播客的参与者数量没有差异。移动的应用程序用户的Twitter帖子（51±11）多于Twitter网站用户（23±6; p<0.05）。与非移动的用户（−2.5±0.5%）相比，播客的移动的用户（−3.5±0.5%）有更大的体重减轻趋势（p=0.055）。Twitter移动的应用程序用户的体重减轻（-5.6 ±0.9%）显著高于网站用户（-2.2 ± 0.5%，p<0.01）。收听播客的设备类型并不影响参与度，但移动的用户有更大的减肥趋势。Twitter发帖的方式与参与度和体重减轻有关，移动的应用程序用户在Twitter上发帖更多，体重减轻更多。
The “m” in mHealth is often thought of as the ability to receive health information and monitor behaviors on the go. Little is known about how people actually use mobile vs. traditional access methods and if access method affects engagement and health outcomes. This study examines the 3-month outcomes of two mobile weight loss interventions (Pounds Off Digitally (POD) and mobile POD (mPOD)) where participants were required to own a mobile device for study entry and received weight loss information via podcast. Only participants in both studies who were randomized to receive the same theory-based podcast (TBP) were used in this analysis. In POD, 41 participants were randomized to the TBP condition (37 to a control not included in this analyses). In mPOD, 49 participants were randomized to the TBP (n=49) and 47 to the TBP+mobile group (a self-monitoring app and Twitter app for social support). The goal of this study is to examine how participants accessed study components and to examine how type of device impacts engagement and weight loss. Examining data from both studies in aggregate, despite a mobile delivery method, 58% of participants reported using a non-mobile device to access the majority of the podcasts (desktop computers), 76% accessed the podcasts mostly at their home or work, and 62% were mainly non-mobile (e.g., sitting at work) when listening. Examining objective download data for mPOD, 49% of downloads (2889/5944) originated from non-mobile delivery methods vs. mobile platforms (3055/5944). At 3 months, 55% of Twitter posts originated from the website (n=665 posts) vs. a mobile app (n=540; 45%). There was no difference in the number of podcasts participants reported listening to by device. There were more Twitter posts by mobile app users (51±11) than Twitter website users (23±6; p<0.05). There was a trend (p=0.055) in greater weight loss among mobile users for podcasts (−3.5±0.5%) as compared to non-mobile users (−2.5±0.5%). Weight loss was significantly greater in Twitter mobile app users (−5.6±0.9%) than website users (−2.2±0.5%, p<0.01). Type of device used for podcast listening did not affect engagement but there was a trend toward greater weight loss among mobile users. Method of Twitter posting was associated with engagement and weight loss with mobile app users posting more to Twitter and losing more weight.
