This session highlighted the evaluation plans and methods for determining the effectiveness of two community-based active living initiatives. The Active Living by Design (ALbD) initiative establishes innovative approaches to increase physical activity through community design, public policies and communication strategies. The evaluation is intended to provide recommendations for building community design initiatives to increase physical activity, including relevant policy and environment changes as well as complementary promotional and programmatic activities. These recommendations will be designed to specifically address environments for children and relatively disadvantaged populations.
