Record linkage of multiple sources was used to ascertain children with intellectual disability born in Western Australia between 1983 and 1992. The prevalence was 14.3 per 1000, 10.6 per 1000 for children with mild or moderate and 1.4 per 1000 for those with a severe level of intellectual disability. Prevalence was greater in males (prevalence ratio 1.6) and in children of Aboriginal mothers (prevalence ratio 2.3). Although prevalence of intellectual disability has been found to vary according to study location, method of ascertainment and criteria used, these estimates are similar to estimates from several recent studies.
通过多源记录链接来确定1983年至1992年间在西澳大利亚出生的智障儿童。患病率为每1000人中有14.3人，轻度或中度智障儿童为每1000人中有10.6人，重度智障儿童为每1000人中有1.4人。男性患病率更高（患病率比为1.6），原住民母亲的子女患病率更高（患病率比为2.3）。尽管已发现智障患病率会因研究地点、确定方法和所用标准而有所不同，但这些估计值与最近几项研究的估计值相似。
