Although distress screening is crucial for cancer survivors, it is not easy for clinicians to recognize distress. Physical activity (PA) data collected by mobile devices such as smart bands and smartphone apps have the potential to be used to screen distress in breast cancer survivors.
The aim of this study was to assess data collection rates of smartphone apps and smart bands in terms of PA data, investigate the correlation between PA data from mobile devices and distress-related questionnaires from smartphone apps, and demonstrate factors associated with data collection with smart bands and smartphone apps in breast cancer survivors.
In this prospective observational study, patients who underwent surgery for breast cancer at Asan Medical Center, Seoul, Republic of Korea, between June 2017 and March 2018 were enrolled and asked to use both a smartphone app and smart band for 6 months. The overall compliance rates of the daily PA data collection via the smartphone walking apps and wearable smart bands were analyzed in a within-subject manner. The longitudinal daily collection rates were calculated to examine the dropout pattern. We also performed multivariate linear regression analysis to examine factors associated with compliance with daily collection. Finally, we tested the correlation between the count of daily average steps and distress level using Pearson correlation analysis.
A total of 160 female patients who underwent breast cancer surgeries were enrolled. The overall compliance rates for using a smartphone app and smart bands were 88.0% (24,224/27,513) and 52.5% (14,431/27,513), respectively. The longitudinal compliance rate for smartphone apps was 77.8% at day 180, while the longitudinal compliance rate for smart bands rapidly decreased over time, reaching 17.5% at day 180. Subjects who were young, with other comorbidities, or receiving antihormonal therapy or targeted therapy showed significantly higher compliance rates to the smartphone app. However, no factor was associated with the compliance rate to the smart band. In terms of the correlation between the count of daily steps and distress level, step counts collected via smart band showed a significant correlation with distress level.
Smartphone apps or smart bands are feasible tools to collect data on the physical activity of breast cancer survivors. PA data from mobile devices are correlated with participants' distress data, which suggests the potential role of mobile devices in the management of distress in breast cancer survivors.

尽管痛苦筛查对癌症幸存者至关重要，但临床医生识别痛苦并不容易。通过智能手环和智能手机应用程序等移动设备收集的身体活动（PA）数据有可能用于筛查乳腺癌幸存者的痛苦。
本研究旨在评估智能手机应用程序和智能手环在PA数据方面的数据收集率，调查移动设备的PA数据与智能手机应用程序中与痛苦相关问卷之间的相关性，并展示与乳腺癌幸存者使用智能手环和智能手机应用程序进行数据收集相关的因素。
在这项前瞻性观察研究中，纳入了2017年6月至2018年3月期间在韩国首尔峨山医院接受乳腺癌手术的患者，并要求他们同时使用智能手机应用程序和智能手环6个月。以受试者内的方式分析通过智能手机步行应用程序和可穿戴智能手环进行每日PA数据收集的总体依从率。计算纵向每日收集率以检查退出模式。我们还进行了多变量线性回归分析，以检查与每日收集依从性相关的因素。最后，我们使用Pearson相关分析测试每日平均步数计数与痛苦水平之间的相关性。
共有160名接受乳腺癌手术的女性患者入组。使用智能手机应用程序和智能手环的总体依从率分别为88.0%（24,224/27,513）和52.5%（14,431/27,513）。智能手机应用程序在第180天的纵向依从率为77.8%，而智能手环的纵向依从率随时间迅速下降，在第180天达到17.5%。年轻、有其他合并症、接受抗激素治疗或靶向治疗的受试者对智能手机应用程序的依从率显著更高。然而，没有因素与智能手环的依从率相关。就每日步数计数与痛苦水平之间的相关性而言，通过智能手环收集的步数计数与痛苦水平显示出显著相关性。
智能手机应用程序或智能手环是收集乳腺癌幸存者身体活动数据的可行工具。移动设备的PA数据与参与者的痛苦数据相关，这表明移动设备在乳腺癌幸存者痛苦管理中的潜在作用。
