Participants - Why?

Asthma is a very common condition which affects the breathing of many children. In fact it is estimated that more than 100,000 children in Scotland and 1 million children in the UK have asthma. There are many millions of children around with world who have asthma.

We now know a lot about what causes asthma and researchers are now working out what can be done to prevent children from getting asthma.

What is less well understood is why asthma is different in some children compared to others. For example some children grow out of their asthma but others don't, some children need lots of treatment to control their symptoms and some don't, some children have symptoms on most days and others only have symptoms every now and then. This is the first study to explore why asthma differs so much between children.

In this study we will look at how things that children eat and breathe in are related to asthma and how genes may be important. For example we will ask the question if a child's genes make them more sensitive to tobacco smoke, do they get more asthma symptoms when they are exposed to tobacco smoke?
