The Neighborhood Quality of Life Study (NQLS), conducted between 2001-2005, was designed to identify environmental correlates of physical activity. This observational study of 2,200 adults aged 20-65 randomly selected from 32 neighborhoods in two regions of the U.S. developed new paradigms and measures for studying built environment associations with health behaviors.
