BACKGROUND: Despite strong evidence for supervised pelvic floor muscle training (PFMT) for women with urinary incontinence (UI), and weight loss and exercise for overweight and obese women with UI, implementation literature on these combined interventions is limited. This paper aimed to describe the rigorous and systematic processes involved in the collaborative development, implementation, refinement and evaluation of a novel, holistic 12 week exercise training and healthy eating group program (ATHENA) for overweight and obese women with UI. METHODS/DESIGN: This intervention description paper is part of a larger mixed-methods feasibility study of implementing the ATHENA intervention within a physiotherapy service at a public hospital in Australia. The collaborative intervention design had input from clinicians, researchers and a consumer representative. RESULTS: The intervention involved four evidence-based components-(1) supervised PFMT; (2) general exercise training; (3) pelvic health education; and (4) healthy eating education-delivered face to face over a 12 week period. Supporting resources developed included a Facilitator's Guide and Participant Workbook. CONCLUSION: ATHENA is an evidence-based, multifaceted, group-based intervention targeting exercise training and healthy eating for management of UI for overweight and obese women. The structured development process and transparency of intervention content and resources aims to enhance practical application and success in future studies.
