Prevalence of childhood asthma in Ulaanbaatar, Mongolia in 2009.

Background: Bronchial asthma is a common but important chronic disease in children in all over the world. To take measures against prevalence of childhood asthma, many researchers have surveyed the actual statuses of childhood asthma in developed countries, but in most Asia-Pacific developing countries including Mongolia such surveys have never been sufficiently conducted until now. We have thought that this survey, though performed in 2009, will give important and meaningful information even now in taking measures to prevent prevailing bronchial asthma in children in Mongolia or the countries under similar statuses.
