I am not sure if someone has done this or not but...If anyone has the
time or interest it might be worthwhile to pull together an annotated
bibliography and put a small fact sheet together. It could separate the
universe of drivers by bus, over the road and the like. We could put it
on our website as a resource and also use it to identify when we might
call for further research. With something like this handy we could speak
more definitively on the topic.
I know we have a lot of students out there and this sounded like a topic
work pursuing. Is it?

There have also been many studies that have shown that
have a very high incidence of heart disease and report high levels of
stress. Their jobs are sedentary, but they have higher exposures to
mobile pollution, stress from traffic, responsibility for safe driving
and sometimes dealing with difficult passenger situations. Studies
conducted over 20 years ago also reported high levels of smoking. A lot
of this research was done at UC San Francisco.

Interesting question, Sara.
This is a SURVEY, not a study, fyi.
Here's a link to their methodology page. While it doesn't say it
weights by SES, they claim to have a representative sample. I'll
leave the parsing to better minds than mine.
Looking forward to the discussion.
The Gallup-Healthways Well-Being Index tracks the well-being of U.S.
residents throughout the year, interviewing no fewer than 500 U.S.
adults nationwide each day, with the exception of major holidays.
Interviews are conducted with respondents on landline telephones and
cellular phones, with interviews conducted in Spanish for
respondents who are primarily Spanish-speaking.
Each daily sample includes a minimum quota of 150 cell phone
respondents and 850 landline respondents, with additional minimum
quotas among landline respondents for gender within region. Landline
respondents are chosen at random within each household on the basis
of which member had the most recent birthday.
Samples are weighted by gender, age, race, Hispanic ethnicity,
education, region, adults in the household, cell-phone-only status,
cell-phone-mostly status, and phone lines. Demographic weighting
targets are based on the March 2009 Current Population Survey
figures for the aged 18 and older non-institutionalized population
living in U.S. telephone households. All reported margins of
sampling error include the computed design effects for weighting and
With the inclusion of the cell-phone-only households and the Spanish
Language interviews, 98% of the adult population is represented in
the sample. By comparison, typical landline-only methodologies
represent approximately 85% of the adult population.
In addition to sampling error, question wording and practical
difficulties in conducting surveys can introduce error or bias into
the findings of public opinion polls.
