A survey of dependency levels was carried out in 1985 and 1989 in 41 residents of old peoples homes and 25 patients in geriatric continuing care wards. There was an increase in all levels of dependency for those in both types of care. In the hospital patients surveyed in 1985, mortality was greatest in the most dependent, particularly those with impaired mental function. There was a positive correlation between length of survival and mental function. The results of this study emphasise the important role of dementia in the health and survival of old people.
1985年和1989年对41名养老院居民和25名老年持续护理病房患者的依赖程度进行了调查。两类护理对象的所有依赖程度水平均有所上升。在1985年接受调查的医院患者中，依赖程度最高的患者死亡率最高，尤其是那些精神功能受损的患者。生存时长与精神功能之间存在正相关。这项研究的结果强调了痴呆症在老年人健康和生存中的重要作用。
