While the conclusions are intuitive, i.e. a statistically significant inverse relationship between Active Transportation and obesity prevalence, it is always helpful to have a study to confirm what we know!

In particular, I found the following paragraph from the attached pdf compelling:

"In the 1980s, few households in China owned automobiles, but 14% of Chinese households acquired an automobile between 1989 and 1997. Bell et al.5 conducted a longitudinal study of 2,485 adults (aged 20 to 45 years) during this time period. They found that Chinese men who acquired a car averaged a 1.8 kg weight gain and were twice as likely to become obese, compared to men whose vehicle ownership remained unchanged. These findings held even after adjusting for diet."
