Canadian study of health and aging, 1991-1992

The Canadian Study of Health and Aging (CSHA) was planned in 1989 as a national longitudinal study to provide accurate statistics on the number of people who have dementia, including Alzheimer's disease, in Canada. The study also covers a range of other health topics. The CSHA involved 10,263 people aged 65 or over, sampled from 36 communities across Canada. Representative samples were drawn from the community and from institutions, and participants were assessed at 5-yearly intervals: in 1991, 1996, and for a final time in 2001. The objectives initially focused on the epidemiology of dementia, and the study has provided estimates of prevalence, incidence and risk factors for dementia, and the burden it places on family caregivers. The CSHA has also described patterns of disability, frailty and healthy aging, and has recorded utilization of health services for different diagnostic groups.

加拿大脑健康与衰老研究（Canadian Study of Health and Aging, CSHA）于1989年立项，作为一项全国性纵向研究，旨在精准统计加拿大境内包括阿尔茨海默病在内的痴呆症患者数量。该研究同时覆盖多类其他健康主题。本研究共纳入10263名65岁及以上受试者，样本源自加拿大全国36个社区，其中涵盖了社区居住人群与养老机构供养人群的代表性样本，并以每5年为间隔开展随访评估：分别于1991年、1996年进行两次评估，最终一次随访于2001年完成。研究最初的目标聚焦于痴呆症流行病学领域，现已产出痴呆症患病率、发病率、危险因素及其对家庭照护者造成的负担等相关评估数据。此外，该研究还阐明了残疾、衰弱与健康衰老的发生模式，并记录了不同诊断群体的医疗服务使用情况。
