Allergic rhinitis in children: incidence and treatment in Dutch general practice in 1987 and 2001

Allergic rhinitis is a common chronic disorder in children, mostly diagnosed in primary health care.

A comparison was made with data from the first (1987) and second (2001) Dutch national surveys of general practice on children aged 0-17 yr. Incidence rates were compared by age, sex, level of urbanization and season. The management of the general practitioner was assessed regarding drug prescriptions and referrals to medical specialists, and compared with the clinical guideline issued in 1996. The incidence rate of allergic rhinitis increased from 6.6 (1987) to 9.2 (2001) per 1000 person-years. We found a male predominance with a switch in adolescence to a female predominance at both time points. The increase in incidence was the highest in rural
