ABSTRACT
Since the end of World War II Americans have moved to suburban neighborhoods in droves. The growth of suburbs has swallowed up forests and farmland at an unprecedented rate. According to the American Journal of Public Health and the American Journal of Health Promotion, suburbanites are on average six pounds heavier than their urban counterparts. More people are retired and living longer than at any other time in history. Physical exercise, especially walking, can help people to live longer lives and possibly even prevent conditions like dementia. Though for years urban planners have stressed the relationship between land uses and transportation as a major contributor to our car-based lifestyles, the public health community now recognizes the relationship between obesity and the dependence on the automobile. Urban areas offer better opportunities for physical activity. Sidewalks are complete and safe, streets are lined with interesting shops and homes that engage walkers and keep them walking farther.
