Mixed-method approach to informing a lifestyle intervention to improve the survivorship of patients with endometrial cancer.

Objectives: To identify endometrial cancer survivors' (ECS) barriers and facilitators for participation in lifestyle interventions to improve their dietary and exercise behaviors. Our secondary objective is to determine baseline information: physical activity level, quality of life (QoL), and impact of COVID-19 on exercise, diet, and mental health.

Methods: Obese, early-stage ECS participated in 2-part mixed-methods data collection; Part 1: survey gathering sample characteristics, QoL, exercise, and basic endometrial cancer- related knowledge. Part 2: virtual focus group or individual interviews using a brainwriting premortem protocol. Statistical analysis was performed using SAS (version 8.3). Qualitative data were analyzed using deductive thematic coding guided by the RE-AIM framework.

Results: Twenty percent (70/358) of ECS from a survivorship database and clinic recruitment completed the survey; 16 ECS provided qualitative feedback. Common barriers to intervention participation included time and resource costs, meeting frequency, and pessimism about weight loss maintenance. Facilitators included an opportunity to connect with other survivors and a focus on health rather than weight loss. Most ECS could not identify exercise guidelines (60%) and 83% were not meeting these guidelines. Higher BMI was correlated with a lower confidence in completing in moderate physical activity (p-value = 0.0206). Post-COVID-19 pandemic, physical activity, nutritional decisions, and/or mental health worsened for 67% of ECS.

Conclusion: ECS are a disparate population, with worsening behaviors and mental health following the pandemic. The identified ECS-specific barriers and facilitators to behavioral intervention participation are being used to simultaneously improve the reach of and adherence to a lifestyle intervention aimed at improving their health and QoL.
