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.
Over the past 5 decades, the TAHS has received over 40 research funding grants and collected data from 45,840 participants. More than 50 researchers and research students have worked on the study.

The new TAHS 7th-Decade follow-up has just commenced. We are inviting all our original 1968 Tasmanian asthma study participants to participate.
The first phase of the study will be a survey. The second phase will involve attending one of our lung function-testing laboratories, similar to our previous TAHS studies. You can read all about the 7th-Decade follow-up here.

Be a part of the future generation of TAHS!
Our research team would like to build on our world-class lung health research by making the TAHS a multi-generational study! We aim to look into whether exposures of the parents, even before the child is conceived, increase the chance of their offspring developing asthma and other lung problems.
