Abstract

The prevalence of childhood asthma has risen dramatically over the past 30 years and continues to increase. It is unclear whether the prevalence of asthma in young adults is also increasing. Methods: A cross-sectional postal survey was conducted using a validated screening questionnaire which gathered data on self-reported respiratory symptoms, including whether asthma had been diagnosed. Questionnaire responses were sought from 4456 adults aged 20-44 years who were randomly selected from the electoral rolls of Higgins, Hotham and Goldstein. Non-responders were sent a reminder card after 4 weeks and a further questionnaire was sent at 6 weeks. Where possible, non-responders were then invited to complete the questionnaire via the telephone. A similar survey was conducted in 1992 in the same geographical area. Results: A response rate of 72% (n=3195) was achieved (46% male). The prevalence estimates for this survey, and for the 1992 survey, are shown in the table.
