Background

Living not just longer, but also cognitively healthier, and more independent lives is essential if European countries are to cope with the financial challenges that the shifting age composition of Europe’s population presents. Here we investigate the change in life expectancy (LE) spent with good and poor cognitive function among older adults across Europe.

Methods

LE with good/poor cognitive function was estimated by the Sullivan Method. Cross-sectional data on cognitive functioning was obtained from 23,213 (wave 1, 2004-05) and 40,874 (wave 6, 2015) 50+-year-olds of the Survey of Health, Ageing and Retirement in Europe (SHARE). Information on mortality was obtained from the Eurostat Database. Results for 70+-year-olds were emphasized.

Results

LE with good cognitive function increased with 1.6 years from 10.7 years (95% CI: 10.6–10.9) in 2004-05 to 12.4 years (95% CI: 12.3–12.5) in 2015 for 70+-year-olds. Disparity was observed across sex and region. In 2004-05, a 70+-year-old woman could expect to spend 30.9% (95% CI: 29.4–32.4) of her remaining LE with poor cognitive function compared to 27.7% (95% CI: 26.0 -29.4) for men. In 2015, women (24.4% (95% CI: 23.4–25.3)) had considerably caught up with men (24.8% (95% CI:23.7.25.8)), shifting the pattern in favor of women. In 2004-05 and 2015, Northern Europeans had the lowest LE with poor cognitive function while Southern Europeans had the highest, but made the most improvement during the period.

Conclusions

Overall we find that LE with poor cognitive function has been compressed in the European population of 70+-year-olds.

2004-05 至 2015 年欧洲老年人口认知功能良好和不良的预期寿命发展

背景

如果欧洲国家要应对欧洲人口年龄构成变化带来的财务挑战，那么不仅要活得更久，而且认知更健康，更独立的生活是必不可少的。在这里，我们调查了欧洲老年人认知功能良好和不良的预期寿命 (LE) 变化。

方法

通过 Sullivan 方法估计具有良好/不良认知功能的 LE。认知功能的横断面数据来自欧洲健康、老龄化和退休调查 (SHARE) 的 23,213 名（第 1 波，2004-05 年）和 40,874 名（2015 年第 6 波）50 岁以上的人。死亡率信息来自欧盟统计局数据库。强调了 70 岁以上人群的结果。

结果

对于 70 岁以上的老年人，具有良好认知功能的 LE 从 2004-05 年的 10.7 年（95% CI：10.6-10.9）增加到 2015 年的 12.4 年（95% CI：12.3-12.5），增加了 1.6 年。性别和地区之间存在差异。在 2004-05 年，一名 70 岁以上的女性预计在剩余 LE 中 30.9% (95% CI: 29.4–32.4) 的认知功能较差，而 27.7% (95% CI: 26.0 -29.4)男人。2015 年，女性 (24.4% (95% CI: 23.4–25.3)) 已大大赶上男性 (24.8% (95% CI:23.7.25.8))，改变了有利于女性的模式。在 2004-05 和 2015 年，北欧人的 LE 最低，认知功能差，而南欧人最高，但在此期间改善最多。

结论

总体而言，我们发现在 70 岁以上的欧洲人群中，认知功能较差的 LE 已被压缩。
