The means of "active transport" - take public transportation, walk, or use the bicycle - are sustainable ways of commuting combining benefits for society: reduction of pollution in the first place. These arrangements also produce benefits for the health of individuals.
 

Adam Martin, from the University of East Anglia (UK), and colleagues analyzed data on 4,056 men and women enrolled in the British Household Panel Survey (BHPS) 2004-5, 2005-6, 2006-7. Participants described the main means of transportation for their daily commute, and provided height and weight (BMI).


Researchers have completed a data analysis to determine whether the changes in the mode of transport are linked to changes in weight over a period of two years. In a preliminary analysis, which included 3,269 participants, 179 people had stopped going to work by car, replacing it with the walk or bike (109) or by public transport (70). The transition from car to walking, cycling or using public transport is associated with a statistically significant reduction in BMI of 0.32 kg / m2 - equivalent to a difference of about 1 kg per person on average. The team found that the longer the journey, the stronger the association, with a reduction in the BMI of 0.75 kg / m2 (equivalent to a weight loss of about 2 kg) associated with transits of more than 10 minutes , and 2.25 kg / m2 associated with displacements of more than 30 minutes equivalent to weight loss of about 7 kg, on average.

In the second analysis, which included 787 people, 268 people went from active to passive detaled travel (car). The transition to self resulted in an increase of weight of about 1 kg per person (or 0.34 kg / m2).

The study's authors argue that: "Measures to allow commuters to switch from individual motorized transport in ways more active travel could help to reduce weight, favoring a greater well-being."
