The Tasmanian Longitudinal Health Study

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 the world’s largest and longest-running study on respiratory health. It started in 1968 and was initially designed to examine the prevalence of asthma in primary school children. Since then, the TAHS has evolved to become an internationally collaborated study and is one of the world’s key studies on asthma and other chronic obstructive pulmonary diseases. More than 50 years since the study commenced, the TAHS participants are still supporting and contribute to the advancement in our understanding of respiratory health. Click here to learn more about TAHS.

What is happening next with the TAHS

We are taking the TAHS into another decade!


Another follow-up study for the TAHS will commence in 2022. This is the TAHS 7th decade study. We are inviting all the participants who were part of the original 1968 Tasmanian asthma study to partake in this study.

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 interested in participating in the survey, 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 or use the contact form

Are you a child of a TAHS participant?

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.

If one of your parents is a TAHS participant, please get in touch with us via one of the following methods:
1. Contact us at 1800 110 711 or use the contact form
2. Use this link to provide us your contact information


We will contact you about potential TAHS studies.

Two new lung function trajectories identified by researchers may predict COPD risk
"Researchers have identified six possible FEV1 trajectories, including two novel trajectories, in a recent cohort study published in The Lancet Respiratory Medicine. Three of the trajectories were associated with modifiable early-life exposures and contributed to 75% of COPD burden...."- June 19th, 2018

Childhood pneumonia and pleurisy lead to smaller lungs: Tasmanian study
"Episodes of childhood pneumonia or pleurisy by age seven are associated with modestly smaller lung volumes in middle age, according to new research. The research, from the Tasmanian Longitudinal Health Study cohort, involved comprehensive measures of lung function in participants at age seven and again at ages 45 and 53" - Nov 6th, 2019
