Smartphone App to Increase and Maintain Physical Activity in African American Men (FitBrothers)

体力活动 (PA) 是许多可预防的慢性疾病的可改变的危险因素，包括 心血管疾病、中风、肥胖和糖尿病。这些条件构成了健康差异 非裔美国男性。行为干预已被证明可以有效促进体能的增加 活动。虽然行为改变计划已被证明可以帮助参与者维持行为 变化中，很少有项目专门针对非裔美国男性。使用移动医疗，而不是 其他干预措施的途径是基于已发表的报告，记录非裔美国人 将移动技术视为可接受的干预手段。此外，所有权 与其他族裔相比，非裔美国人使用智能手机和短信的比例最高 组。因此，针对非裔美国男性的移动医疗干预似乎是可行的，并且有潜力 有效。我们的初步数据显示，一款针对非裔美国男性的 PA 维护智能手机应用程序 包含自我监控、目标设定、强化和行为课程，受到好评 人口。然而，定性数据显示，这些人认为额外的成分是 有必要为非裔美国男性全面定制应用程序，包括个性化、慢性病健康 信息、饮食信息、竞争和激励。此外，我们将根据情况调整干预措施 非裔美国男性的社会文化需求。快速通道 STTR 的目的是将这些 现有智能手机应用程序中的元素。 FitBrothers 应用程序将通过第一阶段开发，包括 (1) 迭代焦点小组，(2) 开发概念模型，以及 (3) 进行 beta 测试和第二阶段 其中包括 (1) 开发完整的 FitBrothers 应用程序，(2) 进行可用性测试，以及 (3) 进行比较有效性试验，以评估该应用程序与类似的、良好的应用程序相比的有效性 市场上知名的应用程序。据我们所知，没有研究利用手机作为影响的手段 非裔美国男性的 PA 水平。 FitBrothers 将解决市场上未满足的需求，因为它将成为 第一个针对非洲裔美国男性 PA 采用和维护的智能手机应用程序。事实 移动医疗是可以接受的，而且该应用程序将与非洲合作开发 美国男性，让我们假设非裔美国男性会将移动医疗干预视为 可接受、可行、有效。快速通道 STTR 提案将由一个共同合作的团队领导 之前包括来自乔治城 Klein Buendel, Inc.

Physical activity (PA) is a modifiable risk factor for a number of preventable chronic diseases, including cardiovascular disease, strokes, obesity, and diabetes. These conditions constitute health disparities for African American men. Behavioral interventions have proven to be effective in promoting increases in physical activity. While behavior change programs have been shown to assist participants in sustaining behavior change, very few programs have specifically targeted African American men. The use of mHealth, as opposed to other avenues of intervention delivery, is based on published reports documenting that African Americans perceive mobile technology as an acceptable means of intervention delivery. In addition, ownership of smartphones and the use of text messaging are highest among African Americans compared to other ethnic groups. Therefore, a mHealth intervention targeting African American men seems feasible and potentially effective. Our preliminary data show that a PA maintenance smartphone app for African American men that contains self-monitoring, goal-setting, reinforcement, and behavioral lessons was well received by this population. However, the qualitative data revealed that the men believed additional components were necessary to fully tailor the app for African American men, including personalization, chronic disease health information, dietary information, competition, and incentives. In addition, we will tailor the intervention to the sociocultural needs of African American men. The purpose of the Fast-Track STTR is to incorporate these elements within an existing smartphone app. The FitBrothers app will be developed through a Phase I consisting of (1) iterative focus groups, (2) developing a conceptual model, and (3) conducting beta testing and a Phase II which will consist of (1) developing a full-scale FitBrothers app, (2), conducting usability testing, and (3) conducting a comparative effectiveness trial to assess the effectiveness of the app compared to a similar, well- known app in the marketplace. To our knowledge, no study has utilized mobile phones as a means of effecting PA levels in African American men. FitBrothers will address an unmet need in the marketplace as it will be the first smartphone app that is targeted toward PA adoption and maintenance in African American men. The fact that mHealth is acceptable to- and the fact that the application will be developed in collaboration with African American men, leads us to hypothesize that African American men will view the mHealth intervention as acceptable, feasible, and effective. The Fast-Track STTR proposal will be led by a team that has worked together previously and includes researchers and multimedia developers from Klein Buendel, Inc. (KB), Georgetown University, and Pennington Biomedical Research Center.
