INTRODUCTION: Recurrent episodes of wheezing are more common in infants especially with low socioeconomic status who are exposed to smoking, who are not breastfed and lives in crowded families.
METHODS: This study was performed prospectively with infants diagnosed as first attack bronchiolitis from the outpatient clinics between 2009 to 2011.
RESULTS: The study included 500 infants aged between 1-24 months. Cigarette smoking was present in 46.6% (n=233) of the families. There was
a significant relationship between recurrent episodes of bronchiolitis and exposure to cigarette smoke
(p<0.001).
DISCUSSION AND CONCLUSION: In this study, exposure to cigarette smoke was detected as a risk factor for recurrent episodes of bronchiolitis. The decrease of smoking
in the population can prevent recurrence of bronchiolitis.
