Objective:

We aimed to investigate the effects of exercise, monitored and managed using smart bracelets, on body composition, and quality of life in breast cancer survivors.

Methods:

A before-and-after study was conducted in 109 patients who were in the recovery phase of breast cancer and attended the Breast Surgery Department of the Cancer Hospital of Fudan University up to December 2017. Patients were advised to adhere to at least 150 minutes of moderate-intensity exercise per week, and a smart bracelet was issued to each participant to record their daily exercise data for 3 months. Bioelectrical impedance analysis was used to observe the effects of short-term unsupervised exercise intervention on body composition in patients recovering from breast cancer. Patients completed the Functional Assessment of Cancer Therapy-Breast to assess health-related quality of life.

Results:

Weight, body mass index (BMI), body fat mass (BFM), fat mass index (FMI), percent body fat (PBF), arm circumference (AC), arm muscle circumference (AMC), and visceral fat area (VFA) were lower than baseline after exercising for 3 months based on data from the wearable devices (P < .05). The only significant improvement was found in the “additional concerns about breast cancer” category among the quality-of-life assessments (P < .05). The average walking time was negatively associated with BFM, PBF, and FMI, while the average calorie consumption due to running was positively associated with fat free mass (FFM).

Conclusion:

In this study, we demonstrated that short-term exercise may be beneficial for postoperative breast cancer survivors. A wearable device could help patients track physical data easily and promote a healthier and more positive life.

基于智能手环监测的短期无监督运动对乳腺癌康复患者身体成分的影响

客观的：

我们旨在调查使用智能手环监测和管理的运动对乳腺癌幸存者的身体成分和生活质量的影响。

方法：

对截至 2017 年 12 月复旦大学肿瘤医院乳腺外科就诊的 109 名处于乳腺癌恢复期的患者进行了前后对照研究。建议患者至少坚持 150 分钟每周中等强度运动，并发给每位参与者一个智能手环，记录其3个月的日常运动数据。生物电阻抗分析用于观察短期无监督运动干预对乳腺癌康复患者身体成分的影响。患者完成了癌症治疗的功能评估 - 乳房以评估与健康相关的生活质量。

结果：

体重、体重指数 (BMI)、体脂量 (BFM)、脂肪量指数 (FMI)、体脂百分比 (PBF)、臂围 (AC)、臂肌围 (AMC) 和内脏脂肪面积 (VFA)根据来自可穿戴设备的数据，在锻炼 3 个月后低于基线 ( P  < .05)。唯一显着的改善是在生活质量评估中的“对乳腺癌的额外关注”类别中发现的( P  < .05)。平均步行时间与 BFM、PBF 和 FMI 呈负相关，而跑步导致的平均卡路里消耗与去脂质量 (FFM) 呈正相关。

结论：

在这项研究中，我们证明短期运动可能对术后乳腺癌幸存者有益。可穿戴设备可以帮助患者轻松跟踪身体数据，促进更健康、更积极的生活。
