A study from the Canadian Healthy Infant Longitudinal Development project at UBC has found links between a child’s exposure to certain factors and developing allergies.
The study says children exposed to air pollution from traffic puts them at higher risk of developing allergies in their first years.
The lead author of a Canadian study says they’ve found some interesting points babies in different cities across the country.
In the study sampling close to 3,000 infants, Vancouver had the most babies developing allergies.
That’s compared to other cities like Toronto and Edmonton.
But Michael Brauer from UBC’S School of Population and Public Health says there are many factors to consider.
“It’s certainly not the air pollution that might be driving that and there may not even be a consistent difference. Factors developing allergy are quite complex. It certainly has to do with things in the environment, in the home, lifestyle factors.”
Brauer adds this is just the first part of the study.
They’ll follow the babies for at least eight years to see if the numbers change.
The study looked at allergies including food, mould and bug sensitivities.
The study also found interacting with other kids at daycare centres – and with their siblings – were also good for their immune systems.
