Most of the university staff commutes.
Values in parentheses relate to sensitivity analysis excluding CO2 from staff commuting to work.
9 Staff commuting—We assumed the distance travelled by staff commuting to work on the trial to be 14 km, which was found to be the average distance commuted to work in the national travel survey 2006.
In pig farms in area A, 'farm staff commuted from outside' was found to be associated with disease transmission.
In pig farms in the movement restriction area, the odds of having factor 'farm staff commuted from outside' was 20 times higher for case farms than control farms.
For pig farms in area A, 'farm staff commuted from outside' and 'fattening farm' were associated with transmission of FMD between farms.
One could argue that staff commuting to work should not be included in the analysis, as the researchers would still need to commute to work even if they were working in another field.
The results of the final model showed that the odds of case farms having the factor 'farm staff commuted from outside' was significantly higher than control farms, with OR = 20.0 (95%CI: 1.8-226.9).
Finally, six explanatory variables were selected for the multivariable analysis; 'farm staff commuted from outside'barnsrns bordered by a road', and 'other people visited the farm' as risk factors and 'fattening farm', 'barn has physical barriers', and 'a forest surrounds the farm' as protective factors.
He said the latter is likely to become increasingly important later in the decade, as rising fuel costs and the need to cut carbon emissions will lead organisations to question the wisdom of requiring staff to commute to work every day.
