Figure 2
Annual changes in worldwide prevalence of asthma symptoms among children 6–7 years old and 13–14 years old, over a mean of 7 years following phase I of the International Study of Asthma and Allergies in Childhood (which in most participating countries was conducted between 1991 and 1993). Blue triangles identify locations where prevalence was reduced by at least 1 standard error (SE) per year, green squares identify locations where there was little change in prevalence (i.e., change of less than 1 SE per year) and red triangles identify locations where prevalence increased by at least 1 SE per year. Reproduced from The Lancet, Vol. 368, Asher MI, Montefort S, Bjorksten B, et al.; ISAAC Phase Three Study Group. Worldwide time trends in the prevalence of symptoms of asthma, allergic rhinoconjunctivitis, and eczema in childhood: ISAAC Phases One and Three repeat multicountry cross-sectional surveys.
