We studied the prevalence and characteristics of coughing and nasal and pharyngo-laryngeal symptoms in 42 children 15 years or younger and 42 adults with Japanese cedar pollinosis via questionnaires in the pollen season in 2009. The prevalence of coughing in children in past pollen seasons was the same as in adults, although pharyngo-laryngeal symptoms were significantly less prevalent in children than in adults. When seen at our clinic, 31.0% of children and 43.6% of adults had coughs, and the difference was not significant. The prevalence of pharyngo-laryngeal symptoms was significantly lower in children than in adults. There was no significant difference between the nasal symptom scores of children and adults. In adults, the nasal obstruction score and the prevalence of postnasal drip were significantly higher in patients with cough than in those without coughs. Although coughing occurs in more than 30% of children with Japanese cedar pollinosis, the prevalence of pharyngo-laryngeal symptoms was low. There is a possibility that the laryngeal allergy is less prevalent in children than in adults.
