Childhood asthma and related allergic conditions have
become the most common chronic disorders in the Western
world.Many studies fromaround theworld have demonstrated
an increasing trend of asthma prevalence over the last few
decades. A few recent reports also suggested that childhood
asthma prevalence may be showing a plateau or even a
decline in few developed countries. Given the rapid changes
in the prevalence over a short period of time, environmental
factors are the more likely candidates explaining such trend.
One of the most consistent epidemiological findings was that
subjects living in the rural areas had lower
prevalence of allergies when compared to those from urban
areas. Clear understanding of the mechanisms of how the
environmental determinants in the rural environment may
affect the early immune system resulting in lower risk of
allergies and asthma will facilitate the development of future
primary preventive strategies. In this study, we review recent
data from around the world and explore the epidemiology
and mechanistic studies that may explain the rural–urban
difference of allergies
