Owens L, et al. - Researchers longitudinally evaluated the prevalence of allergic sensitization, asthma, eczema and hay fever from infancy to adulthood in this prospective study based on a longitudinal birth cohort of 253 participants, with respiratory and immunological assessments at 1, 6, 11, 18 and 24 years of age. The positive skin prick test was used to define allergic sensitization, and a questionnaire was administered for hay fever and eczema. Throughout childhood, variance in the patterns of atopic disorders was observed. An increase was observed in the prevalence of allergic sensitization and hay fever throughout childhood and decline in the prevalence of asthma but the strength of their association with asthma was found to be increased with age.
