Systematic Review of the Use of the Walk-Along Interview Method to Assess Factors, Facilitators and Barriers Related to Perceived Neighborhood Environment and Walking Activity in Healthy Older Adults

Background: Based on findings from a recent systematic review of the methodological aspects related to data collection for the walk-along interview (WAI) method applied to healthy older adults, complementary questions emerged, among them, what are the main outcomes of studies that have used the WAI? Objective: The aim of this systematic review is to identify the outcomes of published studies that have used the WAI method to identify correlates of the perceived neighborhood environment on walking activity in healthy older adults. Methods: In accordance with the PRISMA guidelines, a date-unrestricted search spanning four databases was performed. Of the 164 articles identified in the initial search, 31 articles published between 2012 and 2022 met the inclusion criteria. Results: The extracted outcomes were classified into two categories: (1) the relationship between the physical characteristics of the environment and walking among healthy older adults (e.g., pedestrian infrastructure, safety, access to facilities, aesthetics and environmental conditions) and (2) the facilitators and barriers to walking, based on the dimensions of the socioecological model. Conclusions: This review provides a valuable resource for researchers, students and professionals who wish to work with the WAI method, working on aging and age-friendly cities policies.
