More than 5 million people in the UK suffer from asthma, and we still dont know what causes it. Researchers have drawn up a long list of possible risk factors but findings are frequently contradictory. There is also as yet no clear and uniform definition of what asthma is or consensus how to diagnose it. Dr Bruna Galobardes is searching for some of the answers by looking at how patterns of the disease differ between social classes.
