Wheezing is more common in children less than five years due to small calibre airways and compliance of children lung. In the present study we have studied the prevalence and risk factors of episodic and multi trigger wheezer in children aged less than five years presenting to rural tertiary care hospital at Chidambaram, Tamilnadu.

A structured pro forma was used to obtain data which includes epidemiological profile and risk factors of study population.
Results: In this study among 119 study population, 76 children were multi trigger wheezer and 43 were episodic wheezer.
