Description of intervention(s) / exposure
The intervention is a 12 week, e-health enabled, structured health promotion intervention targeted at improving health related quality of life and reducing chronic disease risk factors in women between 18 and 50 years of age who have previously been treated for cancer. All women in the intervention arm will receive health education material, including a Program Journal (in the form of an interactive iBook), and access to the program website. The iBook includes sections on healthy eating, sleep, exercise advice, tips for managing fatigue and stress, mindfulness, and will encourage women to bring together these various components of the health education provided and incorporate them into their lives over a 12-week period. The iBook includes a weekly exercise planner, where women are encouraged to use this journal daily and to plan ahead for their exercise in the following week. Participants will receive access to self-directed resources (via the website) and three 30-60 minute individual, personalised consultations (via video conference) at weeks 1, 6 and 12 will be provided by a registered nurse trained in the intervention. The nurse consultations will include individual goal setting as well as discussion and health education about physical activity, healthy eating, stress, sleep, menopause and sexuality after cancer and strategies to promote intervention adherence.

Summary
Brief summary
Younger women (50 years of age or younger) treated for cancer represent a growing population in New Zealand. While the treatment outcomes of this cohort have improved, their likelihood of developing treatment-related chronic disease such as diabetes and obesity is considerable, and could pose a significant public health issue in the future. The Younger Women’s Wellness after Cancer Program (YWWACP) is a whole-of-lifestyle intervention that enables younger women to self-manage their chronic disease risk. It promotes physical activity, optimal diet, smoking cessation, alcohol reduction, plus strategies for sleep, stress, sexual wellbeing and menopausal symptom management based on the latest evidence. The Kowhai Study will test the YWWACP intervention and proposed trial design for feasibility in a representative sample of younger New Zealand women (50 years of age or younger) after treatment for breast cancer.
