Tasmanian Infant Health Study (TAHS)

Tasmanian Infant Health Study (TAHS)

Initiatives -
The original aims of the survey were to provide an epidemiological description of childhood asthma, which has a variable natural history requiring: 1. an estimate of its prevalence among children of a suitable age; 2. an estimate of the probability that an individual will change disease status during any given period; 3. an estimate of any secular trend, specifically any tendency for the incidence to vary over time. *Note: All published information has been collected from the article referenced in the Marker Paper box below. Therefore, there may be variations with more advanced versions of the study.*
Start Year
The baseline 1968 study received its initial funding in 1967 from the Tasmanian Asthma Foundation, and since that time the study has received funding from several sources for different follow-up waves and components of the study. Funding bodies have included the National Health and Medical Research Council of Australia (grants #299901, #454425, #566931 #628513 and #1021275); Clifford Craig Medical Research Trust of Tasmania; Victorian, Queensland, and Tasmanian Asthma Foundations; the Australian Lung Foundation; Helen Macpherson Smith Trust; Royal Hobart Hospital Research Foundation; GlaxoSmithKline and the University of Melbourne
