Active Living by Design (ALbD), a national program of the Robert Wood Johnson Foundation, has funded 25 community partnerships across the country to demonstrate how changing community design will impact physical activity.  Funded in 2003 by ALbD, Somerville, MA has initiated Shape Up Somerville as a city wide campaign to increase daily physical activity and healthy eating through programming, physical infrastructure improvements, and policy work.  The campaign follows the 5 "P" strategies identified by ALbD, which include: Preparation, Promotion, Programs, Policy, and Physical Projects.  These strategies represent a comprehensive approach to increasing physical activity in a community.  Researchers at the Institute for Community Health will evaluate this project and determine the extent to which the Somerville Active Living Partnership (SALP) has succeeded in implementing strategies to achieve its 5 "P" goals.  Investigators will evaluate the short-term, intermediary physical activity and lifestyle changes associated with SALP interventions compared with a control community.
