[Hospitalization for bronchiolitis: a risk factor for recurrent wheezing].
This longitudinal study evaluated the role of hospitalization for acute bronchiolitis as a risk factor for recurrent wheezing. Participants were children from a 1993 cohort in a southern Brazilian city. Hierarchical multivariate analysis showed that previous hospitalization for bronchiolitis was the most important risk factor for recurrent wheezing, with an odds ratio of 4.9. This strong association is consistent with a casual relationship hypothesis.
