The world's largest and longest-running study on respiratory health
What is the TAHS?
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 41 research funding grants and collected data from 45,840 participants. More than 50 researchers and research students have worked on the study.
TAHS findings have informed over 80 research articles and 140 conference presentations, influencing new scientific knowledge, clinical practice and Australian policy around respiratory health.

What next for the TAHS?
We are taking the TAHS into another decade!
The new 7th-Decade follow-up has 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.
If you are an original recruit, please update your contact details with us and choose your preferred survey format (online or postal) via one of the following methods:
1. Contact us at 1800 110 711, inq-tas@unimelb.edu.au, or use the

Are you a child of a TAHS participant?
Be a part of the future generation of TAHS!
Our research team is building on our world-class lung health research by making the TAHS a multi-generational study! We aim to investigate whether exposures of the parents, even before the child is conceived, increase the chance of their offspring developing asthma and other lung problems.
If one of your parents is a TAHS participant, please get in touch with us via one of the following methods:
