Allergic rhinitis (AR) is the commonest chronic disease in children. Allergic Rhinitis and its Impact on Asthma (ARIA) classification based on symptom duration (intermittent vs. persistent) and severity (mild vs. moderate/severe) has not been yet validated in children. Thus our objective was to validate ARIA classification in children, after determining the severity and duration of AR in a pediatric population, using ARIA definitions. Children aged 6-12 with a diagnosis of AR were included in an observational, cross-sectional, multicenter study. Patients were classified according to ARIA guidelines. AR symptoms were assessed using the Total Four Symptoms Score (T4SS). Severity was also evaluated by the patient using a visual analogue scale (VAS). Comparisons were made by means of a statistical analysis. One thousand two hundred and seventy-five children from 271 centers were included. Among them, 59.5% had intermittent and 40.5% persistent AR, while 60.7% seasonal and 39.3% perennial according to dated classification, with significant differences existing between one classification and another; 89.7% had moderate/severe rhinitis. Significantly higher T4SS and VAS scores were obtained in moderate/severe compared to mild AR. In our experience, the current ARIA classification can be considered a valid tool also in children from 6- to 12-yr old.
