The American Collage of Sports Medicine evaluates the most populous city areas to determine the healthiest and fittest metro areas in the United States.
Washington DC came in #1 (again) and Baltimore dropped from the 19th place to the 20th slot.
"Characteristics of the D.C. area that helped it achieve the top ranking are a relatively low smoking rate, a higher-than-average percentage of folks eating the recommended daily serving of fruits and vegetables, and lower-than-average rates of chronic health concerns such as obesity, asthma, cardiovascular disease and diabetes. D.C.-area residents also use public transportation regularly, meaning they are likely to walk to and from their places of work or transit stations. Also, the area of parkland as a percentage of the city’s land area is significant, providing residents with lots of space to run, bike, play sports or take a leisurely walk."
