Exploring the impact of targeted exercise in women experiencing homelessness, addiction and mental health challenges: a mixed-methods feasibility study

OBJECTIVE: Low physical functioning and frailty are prevalent in non-geriatric vulnerable populations such as people experiencing homelessness, addiction and mental health challenges. The objective of this study was to explore the feasibility and impact of a targeted exercise intervention with protein supplementation for women experiencing homelessness, addiction and mental health challenges. DESIGN: Mixed-methods feasibility study. SETTING: A women's-only day service for people with homelessness and addiction issues, in Dublin, Ireland. PARTICIPANTS: Women experiencing homelessness, addiction and mental health challenges. INTERVENTIONS: supplementation pre-post programme (LEAP-W). Qualitative interviews were conducted following the intervention with programme participants and key stakeholders. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was feasibility measured by recruitment, retention, adherence, safety and acceptability, and secondary outcomes measured pre-post intervention change in physical function, pain, nutritional and frailty status, and overall health status. RESULTS: Overall, 33 participants were recruited. Data generated demonstrated that LEAP-W was feasible by its safety, acceptability and high retention in certain subgroups, and high adherence to the exercise and protein supplement; its impact was demonstrated by pre-post intervention improvement in multiple domains (strength (chair stand test), balance (the single leg stance test), pain and quality of life/mental health (mental component summary of the Short Form-12; 95% CI, p
