Chinese breast cancer survivors’ functional fitness, biomarkers, and physical activity determinants and behaviors: A descriptive study

Purpose

This study aimed to investigate significant predictors for physical activity (PA) and cancer biomarkers of Chinese breast cancer survivors (BCS), as well as whether differences existed in PA adherence and body mass index (BMI).

Methods

One hundred sixty-eight BCS (mean age = 44.81 years old) participated in the study. Validated surveys discerned PA engagement and psychosocial beliefs. Other outcomes included lipid profiles, fasting serum glucose, cancer biomarkers (i.e., carcinoembryonic antigen [CEA] and cancer antigen15–3 [CA15–3]), and functional fitness.

Results

Results demonstrated that self-efficacy, friend support, lower-right body flexibility, and upper-left body flexibility were significant predictors of participants’ PA levels. CEA significantly associated with participants’ triglycerides, one-hour glucose, and upper-right body strength. For CA15–3, glucose and upper-right body flexibility were significant predictors. No significant overall differences in health outcomes were observed by PA adherence. However, participants’ outcomes differed significantly by BMI.

Conclusion

We found several meaningful predictors of BCS’ PA and cancer biomarkers, which would benefit healthier cancer survivorship. Taken together, the study is imperative for healthcare professionals to realize the importance of promoting a physically active lifestyle and reducing the prevalence of obesity in breast cancer survivors.
