obesity epidemiology

The vol 87 (2009) of the Millbank Quarterly contains a big review on obesity. Sallis and Glanz ( vol 87 pp 123-154) have written a timely reminder that where there is little provision for exercise then obesity is more prevalent. : Numerous cross-sectional studies have consistently demonstrated that some attributes of built and food environments are associated with physical activity, healthful eating, and obesity. Residents of walkable neighborhoods who have good access to recreation facilities are more likely to be physically active and less likely to be overweight or obese. Residents of communities with ready access to healthy foods also tend to have more healthful diets. Environmental, policy, and societal changes are important contributors
to the rapid rise in obesity over the past few decades, and there has been substantial progress toward identifying environmental and policy factors related to eating and physical activity that can point toward solutions
