Rutgers University professor John Pucher has conducted an in-depth study of active commuting and its link to health and wellness.

Published this summer in the American Journal of Public Health, Pucher's study looked at rates of commuting by foot and bike and various health indicators of workers in over a dozen countries.

In comparing workers in every state in the US and 47 of its 50 largest cities, Pucher found that higher rates of walking and biking to work corresponded to:

-higher percentages of adults meeting the US Surgeon General's 30 minutes of daily moderate to vigourous exercise;

-lower percentages of obesity in adults; and

-lower rates of adult diabetes.
