Swimming frequency did not increase the risk of any evaluated symptom, either overall or in atopic children. Children with a high versus low cumulative swimming pool attendance from birth to 7 years had an odds ratio of 0.88 (95% confidence interval, 0.56\u20131.38) and 0.50 (0.28\u20130.87), respectively, for ever and current asthma at 7 years, and a 0.20 (0.02\u20130.39) standard deviation increase in the forced midexpiratory flow. Children with asthma with a high versus low cumulative swimming had an odds ratio for current asthma at 10 years of 0.34 (0.14\u20130.80).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This first prospective longitudinal study suggests that swimming did not increase the risk of asthma or allergic symptoms in British children.
