how long older individuals prefer to live given hypothetical adverse changes in health and living conditions has been insufficiently studied.
the objective of this study is to investigate the relationship between six adverse health and living conditions and preferred life expectancy (PLE) after the age of 60 years.
cross-sectional face-to-face interviews.
population-based sample.
825 community dwellers aged 60 years and older in Norway.
logistic regression models were used to analyse PLE, measured with a single question: 'If you could choose freely, until what age would you wish to live?' The impact on PLE of several hypothetical scenarios, such as being diagnosed with dementia, spousal death, becoming a burden, poverty, loneliness and chronic pain was analysed by age, sex, education, marital status, cognitive function, self-reported loneliness and chronic pain.
average PLE was 91.4 years (95% CI 90.9, 92.0), and there was no difference between men and women, but those at older ages had higher PLE than those at younger ages. The scenarios that had the strongest negative effects on PLE were dementia, followed by chronic pain, being a burden to society, loneliness, poverty and losing one's spouse. PLE among singles was not affected by the prospect of feeling lonely. The higher educated had lower PLE for dementia and chronic pain.
among Norwegians 60+, the desire to live into advanced ages is significantly reduced by hypothetical adverse life scenarios, with the strongest effect caused by dementia and chronic pain.
对于健康和生活条件假设性恶化的情况下，老年人希望能多活多久，这一问题尚未得到充分研究。
本研究旨在调查 6 种不良健康和生活条件与 60 岁以上人群期望寿命（PLE）之间的关系。
面对面的横断面调查。
基于人群的样本。
挪威 825 名 60 岁及以上的社区居民。
使用逻辑回归模型分析 PLE，采用一个问题进行测量：“如果您可以自由选择，您希望活到多大年龄？”分析了几种假设情景（如被诊断为痴呆症、配偶死亡、成为负担、贫困、孤独和慢性疼痛）对 PLE 的影响，分析因素包括年龄、性别、教育程度、婚姻状况、认知功能、自我报告的孤独和慢性疼痛。
平均 PLE 为 91.4 岁（95%CI 90.9，92.0），男女之间没有差异，但年龄较大的人比年龄较小的人期望寿命更长。对 PLE 有最强负面影响的情景是痴呆症，其次是慢性疼痛、成为社会负担、孤独、贫困和失去配偶。单身人士对孤独的预期不会影响 PLE。受教育程度较高的人对痴呆症和慢性疼痛的 PLE 较低。
在挪威 60 岁及以上人群中，对假设性负面生活情景的期望寿命明显缩短，痴呆症和慢性疼痛的影响最大。
