An interesting result from an academic paper:
Researchers found that high levels of exposure to a common type of pollution in pregnancy was \”significantly associated\” with anxiety, depression and attention problems when the children were six or seven.
Academics at Columbia University in New York measured maternal levels of a particular type of pollution caused when petrol or diesel is not burnt properly.
All 253 women they studied, none of whom smoked, were exposed when pregnant to the chemicals, called polycyclic aromatic hydrocarbons (PAHs). Levels varied widely and they found that women exposed to more traffic pollution during pregnancy tended to have children with more behaviour problems.
Sadly I cannot find the paper as the first thing to check is \”how have they controlled for income?\”
Unsuprisingly, low income people tend to live where traffic is heaviest: house prices do change dependent upon whether you\’ve the South Circular or a cul de sac outside your front door.
Low income peeps tend to live where there are worse schools etc as well. There are many things that could link behavioural problems at 6 or 7 years of age with poverty. Things that would be associated with that higher exposure to traffic fumes. But all meaning that unless we\’ve dealt with that income issue, we don\’t actually know whether it is the traffic fumes or not causing the problems.
So, if anyone sees the paper can you let us know how they dealt with it?
