CVD is a major health problem in the United States. Individuals who live in an environment in which it is difficult to maintain an active lifestyle may be more at risk for developing CVD. Because of an increased interest in healthy living, urban planners and architects are now developing neighborhoods that are designed to encourage physical activity. Parks, walking and bicycle trails, wider sidewalks, and community recreation facilities are examples of amenities that are being included in these neighborhoods. By incorporating these enhancements, the Stapleton community in Denver, Colorado has been redeveloped as a more active living environment. The purpose of this study is to determine the effect of the neighborhood environment on the cardiovascular health of residents in five racially, ethnically, and socioeconomically diverse neighborhoods in or near the Stapleton community.
