Association of Allergic Rhinitis and Sinusitis with Childhood Asthma. OBJECTIVE: To study the point prevalence of allergic rhinitis and sinusitis in childhood asthma and to examine the relationship among them. METHODS: In 250 children (age <13 y) with mild-to-moderte asthma, allergic rhinitis was diagnosed by clinical plus nasal eosinophilia criteria, and sinusitis was diagnosed clinically plus confirmation by computerized tomography scan. RESULTS: The point prevalence of allergic rhinitis was 13.6%, and of sinusitis was 2%. On multivariate analysis, allergic rhinitis, sinusitis, and family history were significantly associated with asthma severity. CONCLUSION: Allergic rhinitis is common in childhood asthama, but sinusitis is rare.
