IntroductionPhysical activity has many benefits for older adult physical and mental health. Enhance®Fitness (EF) is an evidence-based group exercise program delivered by community-based organizations. The purpose of this study was to review recent evidence on the dissemination and implementation of EF.MethodsA scoping review of qualitative and quantitative studies with EF as main focus was conducted. CINAHL, PubMed, PubMed Central, SCOPUS, Web of Science, PsycINFO, and Google Scholar were searched between October and November 2015 for data-based studies on EF published in 2010-2015. Two team members abstracted each paper independently using a data abstraction tool. Results were summarized using the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework.ResultsSeventeen publications met inclusion criteria. EF has reached and is effective across a broad population base, including individuals with low SES and diverse ethnic/racial backgrounds. EF participation may be associated with reduced risk for falls requiring medical care, and is associated with fewer hospital admissions. Analyses of medical cost savings from EF participation and program implementation costs suggest economic benefits of EF implementation for communities. Organization-level maintenance is facilitated by program-specific and organizational factors, such as instructor training and funding. Individual-level maintenance is facilitated by program structure, absence of pain, and increased quality of life.ConclusionsMore-rigorous evidence is needed about the association between participation in EF and conditions such as falls. Evaluation of program fidelity, adaptations, and sustainability is limited; more-systematic examination across population groups and types of organizations would help ensure older adults continue to benefit from EF participation.Copyright © 2016 American Journal of Preventive Medicine.
