Change in physical activity and quality of life in endometrial cancer survivors receiving a physical activity intervention.

ABSTRACT: BACKGROUND:Endometrial cancer survivors are at an increased risk of poor quality of life outcomes. Physical activity is positively associated with general quality of life in this population, however, little is known about how changes in physical activity may be associated with changes in specific aspects of quality of life. The aim of this secondary data analysis was to explore the relationships between change in physical activity and change in physical, mental, social, and other aspects of quality of life in endometrial cancer survivors receiving a physical activity intervention. METHODS:Endometrial cancer survivors (N?=?100) participated in a telephone-based physical activity intervention for six months. At baseline and post-intervention we measured physical activity via accelerometry and ecological momentary assessment, and quality of life via the Short Form Health Survey (SF-36), the Quality of Life of Adult Cancer Survivors instrument, the Brief Symptom Inventory, the Pittsburgh Sleep Quality Index, and the Perceived Stress Scale. We conducted structural equation modeling path analyses to investigate how physical activity post-intervention was associated with the quality of life measures' subscales post-intervention, adjusting for baseline levels and potentially confounding covariates. RESULTS:Increasing physical activity was positively associated with improvements in general health (p?=?.044), role limitation due to physical health (p?=?.005), pain (p?=?.041), and somatic distress (p?=?.023). There was no evidence to indicate that change in physical activity was associated with change in other aspects of quality of life. CONCLUSIONS:Endometrial cancer survivors are at higher risk for suffering from challenges to physical quality of life, and findings from this study suggest that increasing physical activity may alleviate some of these problems. Further research is needed to determine whether other aspects of quality of life are linked to change in physical activity.
