Patterns of physical and mental health well-being in older female cancer survivors.

Abstract

173 Background: The majority of cancer survivors are older adults (≥65 years), but their lifestyle behaviors are understudied. Factors associated with improved physical and mental well-being in older female cancer survivors are not well understood. The objective of this study was to evaluate the factors associated with physical and mental well-being in older female cancer survivors, including the role of malnutrition, physical activity, and level of emotional support. Methods: Older female cancer survivors (n=171) completed surveys to assess health related quality of life (HRQoL) using SF-36, malnutrition screening tool (MST), and physical activity. Demographics were also collected. The data was analyzed using descriptive analyses, correlations, and ANCOVAs. Survivors were divided into four phenotypes for analysis using the SF-36 physical and mental composite scores (PCS; MCS) stratified based on the sample’s mean scores (table). Factors associated with the four groups were assessed including demographic characteristics, cancer type, level of emotional support, risk for malnutrition, and physical activity. Results: The majority of the cohort (mean age=74.5 years) were white and highly educated. 68.4% were breast cancer survivors, with 10.5% hematologic malignancy survivors, 5.3% gynecologic malignancy survivors, and 15.8% other. Mean PCS and MCS were 41.94 and 48.47, respectively, comparable to general older adult population means. When divided into four groups based on PCS/MCS, there were no significant differences by demographic characteristics or cancer type. Survivors with higher emotional support scores had significantly higher PCS/MCS scores (p<0.001). There was also a significant difference in risk for malnutrition, as those with high PCS/MCS were at lower risk for malnutrition (p≤0.001). Survivors with low PCS/MCS engaged in less moderate exercise as compared to those with high PCS/MCS (p=0.028). Conclusions: This study suggests that lower risk for malnutrition as well as higher levels of emotional support are associated with higher physical and mental well-being in older female cancer survivors. These are two potential modifiable targets for interventional studies to optimize physical and mental well-being among older cancer survivors. [Table: see text]
