Physical activity correlates and barriers in head and neck cancer patients.

PURPOSE

Our study purpose was to determine physical activity correlates and barriers among head and neck cancer patients.

MATERIALS AND METHODS

Fifty-nine (response rate = 91%) head and neck cancer patients from an academic oncology clinic enrolled in a cross-sectional study utilizing chart review and self-administered questionnaire.

RESULTS

The majority were men (83%) and white (92%) with mean age of 58 +/- 12.8 years and mean months since diagnosis of 18.6 +/- 51.9. The strongest bivariate correlates of physical activity included enjoyment (r = 0.41; p = 0.002), symptom index (r = -0.36; p = 0.006), alcohol use (r = 0.36; p = 0.007), task self-efficacy (r = 0.33; p = 0.013), perceived barriers (r = -0.27; p = 0.047), and comorbidity score (r = -0.27; p = 0.042). Stepwise regression demonstrated independent associations with physical activity for enjoyment (beta = 0.38; p = 0.002) and symptom index (beta = -0.33; p = 0.006; R (2) = 0.28). The most prevalent barriers significantly associated with physical activity included dry mouth or throat (r = -0.32; p = 0.016), fatigue (r = -0.27; p = 0.043), drainage in mouth or throat (r = -0.41; p = 0.002), difficulty eating (r = -0.32; p = 0.015), shortness of breath (r = -0.30; p = 0.024), and muscle weakness (r = -0.29; p = 0.033).

CONCLUSIONS

Our results showed that the strongest independent correlates of physical activity were social cognitive (i.e., enjoyment) and treatment-related (i.e., symptom index). Treatment-related activity barriers were frequent and significantly associated with reduced activity. Efforts to enhance exercise adherence in head and neck cancer patients should focus on optimizing enjoyment and managing treatment-related barriers.
