Whenever I've looked at asthma and causes, I've found studies that attributed it to a wide multitude of causes. "Attributed to" is not the same as "causality." I almost never find an epidemiologist who is willing to say that insult A causes disease B.

Hi Eloisa - Thanks for sending this. Great to see more evidence from other places on this topic. However, I think the California study referred to by the reporter was a pretty solid piece of research - was not involved with it but recall it was not anecdotal
at all.
As many know - Walkability is often highly correlated with increased concentrations of small particulates - a troublesome but solvable twist to the otherwise health benefits of more compact development.

This article in the LA Times may be of interest to you:

Researchers in Europe have confirmed scientifically what parents in traffic-congested Southern California have known anecdotally for years: Poor air quality associated with busy roads can cause
asthma in children.
The study, which examined children’s health in 10 cities, concluded that 14% of chronic childhood asthma cases could be attributed to near-road traffic pollution. It is the first time that medical researchers have made such a direct link
— previous studies stopped at saying that traffic pollution is known to trigger asthma, not cause it.
