title: The Western Australian Twin Register: a population-based register of adult and child multiples.
abstract: The Western Australian Twin Register (WATR) was established in 1997 to study the health of all child multiples born in Western Australia (WA). The Register has until recently consisted of all multiples born in WA between 1980 and 1997. Using unique record linkage capacities available through the WA data linkage system, we have subsequently been able to identify all multiple births born in WA since 1974. New affiliations with the Australian Twin Registry and the WA Institute for Medical Research are further enabled by the use of the WA Genetic Epidemiology Resource--a high-end bioinformatics infrastructure that allows efficient management of health datasets and facilitates collaborative research capabilities. In addition to this infrastructure, funding provided by these institutions has allowed the extension of the WATR to include a greater number of WA multiples, including those born between 1974 and 1979, and from 1998 onwards. These resources are in the process of being enabled for national and international access.
