    Abstract

    BACKGROUND: We explored the nature of the association between severe respiratory syncytial virus (RSV) infection and asthma in a population-based sample of twins. METHODS: Data on hospitalization due to RSV infection was gathered for all twins born in Denmark between 1994 and 2000 (8,280 pairs) and linked to information on asthma obtained from hospital discharge registries and parent-completed questionnaires. Genetic variance components models and direction of causation models were fitted to the observed data. RESULTS: RSV hospitalization and asthma were positively associated (r=0.43) and genetic determinants for the two disorders overlapped completely. Modeling the direction of causation between RSV hospitalization and asthma showed that a model, in which asthma âcausesâ RSV hospitalization fitted the data significantly better (p=0.39 for deterioration in model fit), than a model, in which RSV hospitalization âcausesâ asthma (p
