The electronic Framingham Heart Study (eFHS) is an ongoing nested study, which includes FHS study participants, examining associations between health data from mobile devices with cardiovascular risk factors and disease.
To describe application (app) design, report user characteristics, and describe usability and survey response rates.
Eligible FHS participants were consented and offered a smartwatch (Apple Watch), a digital blood pressure (BP) cuff, and the eFHS smartphone app for administering surveys remotely. We assessed usability of the new app using 2 domains (functionality, aesthetics) of the Mobile App Rating Scale (MARS) and assessed survey completion rates at baseline and 3 months.
A total of 196 participants were recruited using the enhanced eFHS app. Of these, 97 (49.5%) completed the MARS instrument. Average age of participants was 53 ± 9 years, 51.5% were women, and 93.8% were white. Eighty-six percent of participants completed at least 1 measure on the baseline survey, and 50% completed the 3-month assessment. Overall subjective score of the app was 4.2 ± 0.7 on a scale from 1 to 5 stars. Of those who shared their health data with others, 46% shared their BP and 7.7% shared their physical activity with a health care provider.
Participants rated the new, enhanced eFHS app positively overall. Mobile app survey completion rates were high, consistent with positive in-app ratings from participants. These mobile data collection modalities offer clinicians new opportunities to engage in conversations about health behaviors.
电子弗雷明汉心脏研究（eFHS）是一项正在进行的嵌套式研究，纳入了弗雷明汉心脏研究的参与者，旨在研究移动设备健康数据与心血管危险因素及疾病之间的关联。
描述应用程序（app）设计，报告用户特征，并描述可用性和调查回复率。
符合条件的弗雷明汉心脏研究参与者签署知情同意书后，会获得一块智能手表（苹果手表）、一个数字血压袖带以及用于远程进行调查的eFHS智能手机应用程序。我们使用移动应用程序评分量表（MARS）的两个领域（功能、美学）评估新应用程序的可用性，并评估基线和3个月时的调查完成率。
使用增强版eFHS应用程序共招募了196名参与者。其中，97名（49.5%）完成了MARS测评。参与者的平均年龄为53±9岁，51.5%为女性，93.8%为白人。86%的参与者在基线调查中至少完成了一项测量，50%的参与者完成了3个月的评估。该应用程序的总体主观评分为4.2±0.7（满分5星）。在那些与他人分享其健康数据的参与者中，46%分享了他们的血压数据，7.7%与医疗服务提供者分享了他们的身体活动数据。
参与者对新的增强版eFHS应用程序总体评价积极。移动应用程序调查完成率很高，与参与者在应用程序内的积极评分一致。这些移动数据收集方式为临床医生提供了就健康行为展开对话的新机会。
