Another factor to consider is the length of time people sit in traffic.
The pollution from idling vehicles is substantial and has been shown to
effect cardiac health. I have attached a review article about health
impacts of ultrafine particulates written by several colleagues.
Also, you might wish to look at: L, Williams RW, Devlin RB: Particulate
matter exposure in cars is associated with cardiovascular effects in
healthy young men. American Journal of Respiratory and Critical Care
Medicine 2004, 169:934-940

Nice to see, be sure to read Todd Litman's
excellent response.
I agree with Todd that the title is overstated; the article is asking us
to question whether confounding factors are also important, perhaps
separate from transportation (and land use) behaviour/characteristics,
which was not to say transportation factors have no effect. I also agree
with Todd that a county-level analysis misses the variations in land use
(and other factors) that occur within counties. This is great for a
regional view, but not for a total analysis.
The authors suggest such confounding factors as:
- food choices
- sedentary hobbies
- stress
- unemployment rates
- regional culture
I would counter, for one, that we consider car culture to be larger than
just the modal split. Would people eat at drive-through restaurants if they
could conveniently and comfortably walk food sources? Would people shuttle
children as much if those destinations were more available by other means?
Please don't take my statements as comprehensive, I know this is very
broad and I too just ask us to think more broadly.
In terms of analysis by gender, Marsha, the did not look at gendered
factors, although the bio of one of the two authors, Anne Price, states
that her "teaching and research specializations are in cross-national
sociology and methodology, with a particular focus on women’s health and
status".
The article looked at county-level data to get a visual idea of large
scale regional differences. I don't know if the ratio of males to females
varies much across the country in that way. Other gendered behaviors
certainly could; who does the shopping and driving of children, for
instance? Is that more common in the "Bible Belt" than New England, for
instance? The article and the topic as a whole invites a great deal of
inquiry.

What is the relationship between car travel and health outcomes in the
United
States? Ariel Godwin and Anne Price challenge the claim that more
time in the car decreases your health by looking at the impacts of
education, income, and employment rates.
