A study led by Adnan Custovic from the University of Manchester analyzing two surveys ten years apart (1993 and 2003) among 9-16 year old schoolchildren attending urban and rural schools in Ghana showed that the prevalence of both exercise-induced bronchospasm and atopy had approximately doubled over the period.
