科学领域:

  • 神经学 神经学
  • 流行病学 流行病学
  • 老年学是一门学科.

背景情况:

  • 糖尿病,高血压和吸烟等中年血管风险因素与痴呆和死亡率有关.
  • 之前的研究研究了个别的风险因素,但对痴呆和寿命的综合影响尚不清楚.
  • 了解这些关联对于开发健康衰老干预措施至关重要.

研究的目的:

  • 调查中年血管风险因素对痴呆发病和预期寿命的联合负担.
  • 量化多种风险因素对无痴呆年数和患有痴呆的年数的影响.

主要方法:

  • 从社区动脉样硬化风险 (ARIC) 研究中对12,409名参与者的前性队列分析.
  • 参与者根据中年血管风险因素的数量进行了分层 (0,1,2或3)).
  • 累积发病率函数和卡普兰-梅尔方法用于估计痴呆和死亡风险,以及痴呆和没有痴呆的预期寿命.

主要成果:

  • 57.5%的参与者至少有一个中年血管风险因素.
  • 具有三种风险因素的个体在55岁时无痴呆年数为17.5年,而没有风险因素的个体为30.1年.
  • 较高的血管风险负担与增加的死亡率相关,导致终身痴呆风险较低,但患痴呆症的年龄较长.

结论:

  • 较大的中年血管风险因素负担与早期痴呆发作和减少无痴呆预期寿命 (长达13年) 有关.
  • 增加的死亡率与较高的血管风险负担显著影响预期寿命,增加 2-4 年的痴呆症.
  • 需要紧急实施中年血管健康干预措施,以延迟痴呆症并增强大脑健康.
