Objective: To identify whether clusters of symptoms (depression, anxiety, fatigue, cognitive limitations) appear in employed breast cancer survivors, and whether clusters are related to job stress and aerobic activity.
Methods: Employed breast cancer survivors (n = 94) and women without a history of cancer (n = 100) completed questionnaires online in a cross-sectional study.
Results: A two-cluster solution of high or low symptom severity groups was observed. High symptom cluster was associated with breast cancer (odds ratio [OR] = 2.46; 95% confidence interval [CI], 1.22 to 4.93), more frequent job stress (OR = 1.78; 95% CI, 1.12 to 2.83), and lower levels of aerobic activity (OR = 0.55; 95% CI, 0.36 to 0.83).
Conclusion: Levels of anxiety, depression, cognitive limitations, and fatigue are expressed as clusters with varying severity. Clusters are related to job stress and aerobic activity in breast cancer survivors at work. Findings suggest avenues for clinical management and research.
