334 Determinants of Health Affecting Self-Efficacy and Quality of Life in Patients with Prostate Cancer

OBJECTIVES/GOALS: Our long term goal is to identify the socioeconomic and cancer-specific determinants in patients with prostate cancer undergoing prostatectomy that impact their ability to maintain a healthy weight. This study explores the association between participants’health determinants and their indicated degree of self-efficacy and quality of life (QoL). METHODS/STUDY POPULATION: Study population includes participants of the WARRIOR trial (n=40), which included overweight men scheduled radical prostatectomy from the University of Kansas Medical Center. In addition to baseline demographics, the study team will administer a questionnaire based on a socioeconomic position and health-related QoL framework. This questionnaire will assess participants' socioeconomic, cancer-specific, and psychological circumstances at time of surgery and present day. Univariate analyses will be conducted on all variables with bivariate analyses between socioeconomic and clinical items to the outcome of composite self-efficacy scoring. RESULTS/ANTICIPATED RESULTS: We anticipate that participants in the intervention will report higher self-efficacy and emotional/social support than participants in the control group, participants with social vulnerability (lower income, marginalized race/ethnicity, etc) will report decreased self efficacy and poorer QoL compared with participants who are not socially vulnerable, and that participants who previously indicated social vulnerability will report more emotional barriers to weight loss, and lesser weight loss satisfaction, self-esteem, and QoL. DISCUSSION/SIGNIFICANCE: Lifestyle interventions have helped prostate cancer patients lose weight before surgery, but many regain weight. Exploring perceptions of self efficacy as well as learning more about what structural and systemic barriers affect self efficacy is important to inform how to improve our approach for sustained weight loss and health behavior changes.
