Built Environment Implementation Strategies to Promote Physical Activity: Expert Consensus for Local Implementation of Physical Activity Policy, Systems, and Environment (ECLIPPSE).

Context: Despite evidence supporting the role of the built environment in promoting physical activity, there is limited guidance on how to implement recommended built environment changes at the local level.

Objectives: The objective of this project was to develop a compilation of implementation strategies that hold promise for aiding communities in implementing built environment changes that support active transportation and leisure-time physical activity, titled "Expert Consensus for Local Implementation of Physical Activity Policy, Systems, and Environment (ECLIPPSE)."

Design: A modified Delphi Technique using 3 web-based survey rounds was conducted from 2024 to 2025.

Setting: A multidisciplinary national expert panel was recruited to participate in this online panel.

Participants: The panel consisted of 23 professionals with expertise in the implementation of built environment changes to support physical activity at the local level.

Main outcome measure: The Round 1 and 2 surveys utilized a rating process to establish a compilation of potentially promising strategies for aiding communities in implementing physical activity-supportive built environment changes. The Round 3 survey involved rating these strategies on potential feasibility and impact and endorsing the final compilation.

Results: Fifty-five strategies emerged in 2 broad domains. The first domain, "Get Ready," included 4 categories: (1) Partnerships and collaboration (5 strategies); (2) staffing (5 strategies); (3) training and education (4 strategies), and (4) interactive assistance (2 strategies). The second domain, "Take Action," included 6 categories: (1) Data and community informed prioritization (6 strategies); (2) evaluative (8 strategies); (3) community awareness and demand (8 strategies); (4) engagement with decision-making processes (5 strategies); (5) funding (7 strategies); and (6) pilots or demonstration projects (5 strategies). The final compilation was endorsed by 95% of respondents.

Conclusions: The ECLIPPSE strategies can be used to aid implementation of built environment changes at the local level to support physical activity.
