Exploring the Role of the Built Environment on the Functional Ability and Social Participation in Community-dwelling Older Adults.

Background and objectives: The built environment or physical environment consists of surroundings and conditions constructed by human activity. It includes urban design, neighborhoods, transportation, and smaller scale structures like the design and layout of rooms within buildings. The built environment can affect the physical, social, and functional wellbeing of older adults, both within their own homes and in the neighborhoods in which they live, and additionally plays a part in promoting healthy aging. This narrative review of the literature aims to present the ways in which the built environment can influence the functional ability of community-dwelling older adults, and affect their ability to live independently and age in place.

Methods: Narrative literature review and inductive thematic analysis.

Results: Forty-five full-text, English language publications from peer-reviewed sources were selected for this review, with the majority (35) presenting quantitative research findings and originating from North America (28). Older adults in rural and developing countries were underrepresented in the literature, despite acknowledgement that health of the aging population is a worldwide problem. Three major themes emerged. First, the built environment affects older adults in the most fundamental way at home through design considerations, modifications, and technological advances promoting aging in place and accessibility. Secondly, built environments outside the home can affect older adults' physical activity and overall function with regard to mobility, transportation, and activities of daily living. The majority (22 of 45 publications) focused on this theme. Finally, the built environment in neighborhoods can affect older adults' perception of social support, their social participation, and quality of life.

Conclusion: As the built environment is created by humans and can be substantially modified, it possesses considerable potential for enhancing functional ability, social participation, and overall quality of life in community-dwelling older adults. It is possible to design a better person-environment fit, promoting safety, independence, optimal health, and quality of life. In order to support healthy aging, improvements in the built environment need to be accompanied by appropriate health and social policies, systems, and services. These changes require political will, as well as material resources that may not be readily available especially in the global South. A socioecological approach with adequate resources directed to older adults' health and healthcare is necessary in order to achieve the ultimate goal of healthy aging in this population.
