<abstract abstract-type="main" id="apa12736-abs-0001"> <title>Abstract</title> <sec id="apa12736-sec-0001" sec-type="section"> <title>Aim</title> <p>Infant swimming has been considered as a risk factor for wheezing, but the role that respiratory viruses play is unclear. We explored the effects of infant swimming on the risk of all wheezing illnesses and wheezing associated with rhinoviruses.</p> </sec> <sec id="apa12736-sec-0002" sec-type="section"> <title>Methods</title> <p>We followed up a birth cohort of 1827 children until 17 months of age, collecting data on infant swimming, other risk factors and physician‐diagnosed bronchiolitis or recurrent wheezing. Viral diagnostics were performed in a subset of children with all respiratory tract infections.</p> </sec> <sec id="apa12736-sec-0003" sec-type="section"> <title>Results</title> <p>Data on infant swimming were obtained for 1038 children, with viral follow‐up for 635 children. At least one wheezing illness was documented in 45/469 (9.6%) swimming children versus 39/569 (6.9%) nonswimming children (p = 0.11), and rhinoviruses were associated with wheezing in 11/296 (3.7%) swimming children versus 4/339 (1.2%) nonswimming children (p = 0.04). In adjusted logistic regression analyses, swimming had an odds ratio of 1.71 (p = 0.05) for bronchiolitis and 3.57 (p = 0.06) for rhinovirus‐associated wheezing. An association between infant swimming and rhinovirus‐associated wheezing was detected for children with atopic eczema (p = 0.006).</p> </sec> <sec id="apa12736-sec-0004" sec-type="section"> <title>Conclusion</title> <p>There may be a link between infant swimming and rhinovirus‐induced wheezing illnesses in atopic infants.</p> </sec> </abstract>
