| Summary: | © 2014 John Wiley & Sons A/S. Introduction: Asthma is associated with diminished health-related quality of life (HRQoL). Particularly in adolescence, asthma may be under-diagnosed and undertreated or poorly managed. Therefore, we aimed to determine the association between childhood wheezing phenotypes rather than asthma and adolescent HRQoL in children aged 10-17 yr. Methods: We analyzed the data from two prospective population-based cohort studies (n = 604 and n = 1804) conducted in southern Germany with baseline assessments in 2000 and 2006 and follow-ups at frequent intervals. Parent-reported wheeze was categorized into never, early transient, persistent, and late-onset wheeze. We assessed child-reported HRQoL in seven scales using the validated KINDL-R. Multivariate linear regression models were computed. Results: Participants with late-onset wheeze had significantly lower values in all HRQoL scales, but physical well-being compared to never wheezers. Early transient wheeze was negatively associated with three HRQoL scales only (family, school, and total). These effects were confined to the oldest age group (=13.5 yr) in one study. Persistent wheeze was not associated with HRQoL. Conclusions: In teenagers, late-onset wheezers seem to be particularly vulnerable for impairments in psychosocial aspects of health-related quality of life.
