About
The Tasmanian Longitudinal Health Study (TAHS), previously known as the Tasmanian Asthma Study, is a longitudinal cohort study on respiratory health. It was started in 1968 to examine the prevalence of asthma in primary school children in Tasmania. Almost every 7 year-old at school in Tasmania was recruited into the study. Later their parents and siblings were also included. Since then, the TAHS has evolved into an internationally collaborated study of respiratory diseases. More than 50 years since the study commenced, TAHS participants are still contributing data which advances our understanding of respiratory health.
