Leveraging Fitness Tracker and Personalized Exercise Prescription to Promote Breast Cancer Survivors' Health Outcomes: A Feasibility Study

摘要

Purpose: This feasibility study investigated whether a year-long combined fitness wristband-based and personalized exercise prescription intervention improves Chinese breast cancer survivors' (BCSs) health outcomes. Methods: Ninety-five BCSs (X-age= 44.81 +/- 7.94;X-BMI= 22.18 +/- 3.48) were recruited from Southern region of China and were delivered the exercise intervention across 12 months, using a single group pretest-posttest design. Participants' lipid profile (e.g., totalcholesterol, high-density lipoprotein, low-density lipoprotein, and triglycerides), blood glucose, breast cancer biomarkers (e.g., carcinoembryonic antigen and cancer antigen 15-3), and functional fitness (e.g., strength in arms and legs, endurance, balance, agility, and flexibility) were assessed at baseline and 12-month post-intervention. Results: Thirty-three BCSs successfully completed the intervention. A significant change in blood glucose (mean difference (MD): -0.22, 95% confidence interval (CI): -0.41--0.03,t= -2.25,p= 0.028) was observed, with participants demonstrating lower levels of blood glucose at the 12-month post-intervention versus the baseline assessment. Notable changes in functional fitness were also discerned, including agility and balance (MD: -0.47, 95% CI: -0.68--0.26,t= -4.336,p< 0.001), aerobic endurance (MD: 89.25, 95% CI: 73.82-104.68,t= 11.336,p< 0.001), lower-body flexibility (left) (MD: 4.58, 95% CI: -4.4-13.56,t= 4.653,p< 0.001), and lower-body flexibility (right) (MD: 4.84, 95% CI: -4.65-14.33,t= 4.092,p< 0.001). Conclusion: The observations suggested that our behavioral change program might promote certain health outcomes in Chinese BCSs, yet we are unable to recommend such a program given existing limitations. Future randomized control trials with diverse samples are warranted to confirm our findings.
