Hospital admissions for asthma in east London are 80% above the national rates. This may reflect the high incidence of acute asthma. Recent reports of a higher prevalence of wheeze1 2 or hospital admissions in children in association with traffic flow or proximity of residence to roads3 have highlighted concerns about the possible health effects of road traffic in the London Borough of Tower Hamlets.

In each of two computerised general practices in Tower Hamlets around 20% of the population have received computer prescriptions for bronchodilators, inhaled steroids, or inhaled anti-inflammatory drugs since 1990.
