ENABLE: ENhAncing lifestyle Behaviours in endometriaL cancEr

Supportive care intervention of social support and lifestyle education (nutrition and physical activity (PA)) with behavior change support. In addition to usual care, women randomised to the intervention group will receive an eight-week multi-disciplinary program to improve lifestyle behaviours (nutrition and physical activity) coupled with social support and behaviour change techniques. The initial multi-disciplinary session (up to 1.5 hours duration) will be conducted as an individual face-to-face session involving all three clinicians at Peter MacCallum Cancer Centre. Subsequent weekly individual follow-up (20-30 minutes duration) will be completed via telehealth (or face-to face if preferred by participants). All intervention sessions will be scripted to ensure a standardised content is covered for all intervention group participants. Each intervention session will include aspects of social support, lifestyle education and behaviour change. The social worker will work with participants to identify issues which may act as barriers to participants being able to make changes to their current nutrition and physical activity behaviours. This may involve referral to support services within the community. The dietitian and physiotherapist will provide education regarding good nutrition and increasing physical activity which is individualized and based on baseline assessment findings and patient preferences. It is anticipated that many participants will choose walking as their preferred form of physical activity. Participants will be encouraged to exercise at a moderate intensity level, commencing at a minimum of 10 minute bouts and gradually increasing to meet the physical activity recommendations of 150 minutes of moderate intensity aerobic exercise per week. To increase social support for changing lifestyle behaviours a family member or friend of the intervention group participant will also be encouraged to attend face-to-face and telehealth consultations and participate in the PA program where possible. Recommended nutrition, weight management and PA and associated benefits for people with endometrial cancer will be discussed and standard written educational material, developed by the Peter MacCallum Cancer Centre, will be provided. Participants will work with the health professionals to establish a home-based PA program and develop individualised, patient-centred nutrition and PA-related short and longer-term goals. In addition to goal setting, behaviour change strategies will include action planning, barrier identification/problem solving, self-monitoring of behavioural outcomes (using an activity monitor and diary), relapse prevention/coping planning and providing feedback regarding performance.
