Previous studies, published in The Lancet, connected the design of cities and growing epidemics of injuries, such diseases as heart disease, diabetes and cancer. In part three of the series of studies, researchers explain how to implement timely research to build healthier cities, planning and policy to improve the health of people living in cities.
Scientists predict that by 2050, the large cities in the United States of America, China, and India will increase their populations by 33%, 38% and 96%. And these increasing will lead to declines in physical activity, increases in air pollution and higher rates of road death and serious injury.
James F. Sallis, PhD, UC San Diego School of Medicine Distinguished Professor of Family Medicine and Public Health and first author of the paper, said: “Shifting from city infrastructure that encourages the use of automobiles to a design providing safe and easy walking, cycling and public transportation options would reduce traffic injuries, air pollution and physical inactivity.”
