Genetic epidemiology of chronic respiratory diseases from childhood to adulthood: A prospective study of sibships

Funded Activity Summary

Chronic Respiratory Diseases (CRDs) are a major public health problem. It is known that CRDs change over time but we have no information on causes of these changes. Some childhood asthmatics continue to have asthma as adults and-or develop Chronic Obstructive Pulmonary Disease (COPD) while others are free of any adult CRD. Some of those who do not have childhood asthma develop asthma and-or COPD as adults while the others remain free of CRDs from childhood to adulthood. To investigate risk factors for these changes, following up siblings over time is a powerful tool. As siblings share the childhood environment but not the adult environment, it helps to disentangle childhood environment, adult environment and genetic factors. The Tasmanian Asthma Study (TAS) is amongst worlds' major longitudinal respiratory studies and it is unique because it was conceived as a family study, with all the family members and the family environment being surveyed. TAS commenced in 1968 by investigating 8,585 school children born in 1961 (referred to as probands), their parents (16,267) and siblings (21,044). By the end of 2006, we will have completed the 37-year follow-up of the TAS probands, which focuses on non-genetic risk factors for middle-age CRDs. This follow-up together with baseline data now provides a unique opportunity for conducting a sibling study, which can concurrently examine genes, childhood environment and adult environment for change in CRDs. Also, it will provide a platform for future studies to investigate the progression of CRDs in this family cohort. Therefore, we now seek funding to extend the current follow-up to include the siblings. This will be the world's only population-based respiratory sibling study that spans childhood to adulthood. This will provide information for preventing chronic respiratory morbidity and disability in the future, which will be original and significant not only in Australia but also internationally.
