科学领域:

  • 神经科学是一个神经科学.
  • 公共卫生 公共卫生
  • 老年学是一门学科.

背景情况:

  • 提供认知效益所需的体力活动 (PA) 的确切数量和模式仍然不完全理解.
  • 现有研究尚未确定最佳的PA策略来预防痴呆症.

研究的目的:

  • 调查中度至强度体力活动 (MVPA) 和轻度体力活动 (LPA) 不同水平和模式与痴呆发病率之间的关联.
  • 确定PA模式 (度与分布) 和LPA是否可以减轻痴呆风险.

主要方法:

  • 利用了来自英国生物库的91,512名参与者的数据,用加速度计测量了PA.
  • 采用考克斯比例危险回归来分析MVPA,LPA和痴呆发病率 (所有原因,AD,VaD) 之间的关联.
  • 检查了PA梯度,强度模式 (周末和常规),以及LPA对低MVPA的个体的影响.

主要成果:

  • 超过300分钟/周的MVPA与痴呆症风险降低有显著的关联,不管它是在1-2天内积累的还是定期分配的.
  • 痴呆症的危险比为周末MVPA模式的0.73和常规模式的0.79,与<150分钟/周相比.
  • 对于低MVPA的个体来说,积累超过840分钟/周的LPA与更低的痴呆发病率有关.

结论:

  • 累积超过300分钟/周的MVPA与痴呆症风险降低有关,这凸显了足够的活动量的重要性.
  • 包括集中周末活动在内的PA模式显示,在降低痴呆风险方面具有潜在的好处.
  • 轻度体力活动 (LPA) 可以部分抵消与MVPA不足相关的痴呆风险,这表明它在认知健康中起着补充作用.
