Abstract

Rationale: Better characterization of childhood wheeze phenotypes using newer statistical methods provides a basis for addressing the heterogeneity of childhood asthma. Outcomes of these phenotypes beyond childhood are unknown. Objectives: To determine if adolescent respiratory symptoms, lung function, and changes in lung function over adolescence differ by childhood wheeze phenotypes defined through latent class analysis. Methods: A prospective birth cohort (Melbourne Atopy Cohort Study) followed 620 high allergy-risk children, recording respiratory symptoms and spirometry at 12 and 18 years. Regression analyses identified relationships between wheeze phenotypes (never/infrequent, early tra..
