科学领域:

  • 神经学 神经学
  • 心血管健康 心血管健康
  • 老年学是一门学科.

背景情况:

  • 高血homocysteine (Hcy) 是心血管疾病和中风的已知危险因素.
  • 血Hcy对认知障碍的具体影响仍未得到充分研究,特别是在亚洲人群中.

研究的目的:

  • 研究中老年和老年中国人血Hcy水平与认知障碍之间的关联.
  • 确定Hcy升高是否是认知能力下降的独立风险因素.

主要方法:

  • 一项以社区为基础的横截面研究,涉及1,805名参与者 (≥40岁) 在中国西安.
  • 认知功能使用迷你精神状态检查 (MMSE) 和神经心理尺度进行评估;认知障碍根据既定标准诊断.
  • 血Hcy水平分为三级;用于分析的多变量逻辑回归和受限制的立方线.

主要成果:

  • 认知障碍的患病率为8.0% (145/1805),随着Hcy三位数较高 (4.9%至12.2%),显著增加.
  • 升高的Hcy水平独立地与更高的认知障碍风险相关 (OR=1.029每单位增加,p=0.001).
  • 高水平的Hcy (与低水平相比) 显示了显著增加的风险 (OR=1.89,p=0.010),没有检测到非线性关系.

结论:

  • 血Hcy水平升高与这种人群认知障碍的可能性增加有显著联系.
  • 需要进一步的队列干预研究,重点关注降低Hcy,以确认因果关系并探索治疗策略.
