背景。迄今为止，健康规划者和倡导团体可获得的关于智力障碍者预期寿命的代表性数据相对较少。对智力障碍者的生存状况趋势进行了研究，以协助规划适当的医疗和支持服务。方法。自 1953 年以来，西澳大利亚州残疾人服务委员会一直维护着一个被诊断为智力障碍者的数据库。该数据库用于计算总共 9724 人的生存概率，其中 7562 人在 2000 年 12 月采样时仍然活着。 结果。 Kaplan-Meier 生存图显示，智力障碍的严重程度与生存率之间存在很强的负相关关系，轻度、中度和重度障碍者的中位预期寿命分别为 74.0、67.6 和 58.6 岁。还观察到与男性、澳大利亚土著血统以及被诊断患有特定遗传性疾病的个体之间存在显着的负相关。结论。调查结果表明，在过去两代人中，老龄化、智力障碍人群的服务需求大幅增长且不断扩大。
Background. To date, relatively few representative data have been available to health planners and advocacy groups on the life expectancy of people with intellectual disability. A study of trends in the survival profiles of people with intellectual disability was undertaken to assist in the planning, of appropriate medical and support services.Methods. Since 1953, the Disability Services Commission of Western Australia has maintained a database of persons diagnosed with intellectual disability. The database was used to calculate survival probabilities on a total of 9724 individuals, 7562 of whom were still alive at the time of sampling in December 2000.Results. Kaplan-Meier survival plots showed a strong negative association between severity of intellectual disability and survival, with median life expectancies of 74.0, 67.6, and 58.6 years for people with mild, moderate, and severe levels of handicap. Significant negative associations also were observed with male gender, Indigenous Australian parentage, and individuals diagnosed with a specific genetic disorder.Conclusions. The findings indicate a major and expanding increase in the service requirements of this aging, intellectually disabled population during the past two generations.
