We keep hearing (and seeing) that people in the U.S. are getting heavier. The CDC says about 65 percent of U.S. adults (over 20 years old) and 15 percent of children and adolescents are overweight. As for obesity, 2005-2006 data from the National Center for Health Statistics data shows adult male obesity in the U.S. at 33.3 percent, 35.3 percent for adult females and 16.3 percent for children and adolescents aged 2?EUR??,,????'?????<???????????????????????(R)??????oe19.

A study in the Sept. 2008 American Journal of Preventive Medicine (?EUR??,,????'?????<?????????????????Walkability and Body Mass Index Density, Design, and New Diversity Measures,?EUR??,,????'?????<????????????????? by Ken R. Smith PhD, et al.) concludes that people lower their risk of obesity when they live in densely populated, urban neighborhoods.
The study ?EUR??,,????'?????<?????????????????relates neighborhood walkability?EUR??,,????'?????<????????????????????density, pedestrian-friendly design, and two novel measures of land-use diversity?EUR??,,????'?????<????????????????????to residents?EUR??,,????'?????<???????????????????????(R)?EUR??,,????'???? excess weight.
Walkable-environment measures include two established predictors?EUR??,,????'?????<????????????????????higher density and pedestrian-friendly design (intersections within 0.25 mile of each address)?EUR??,,????'?????<????????????????????and two new census-based, land-use diversity measures: the proportion of residents walking to work and the median age of housing.?EUR??,,????'?????<?????????????????
The University of Utah researchers examined census data from half a million state residents and found male suburbanites on average weighed 10 pounds more than their city-dwelling counterparts. The women had a weight difference of six pounds.
The researchers found the two land-use diversity measures particularly important predictors of body weight and noted the weight differential was especially pronounced in urban neighborhoods developed before the 1950s, i.e., those neighborhoods built before the car culture took over, where it?EUR??,,????'?????<???????????????????????(R)?EUR??,,????'????s easy for residents to walk to parks, restaurants and shops from their homes.
While it?EUR??,,????'?????<???????????????????????(R)?EUR??,,????'????s no revelation that more physically active people tend to weigh less than their more sedentary souls, the researchers believe the study numbers should be an incentive for city planners to focus more on design neighborhoods with pedestrians in mind and, perhaps, prompt even the couch potato to take a walk to eat that next meal.
