更高的主观幸福感 (SWB) 与心血管事件风险降低有关. 这种关联可能通过代谢和血液动力学途径运作,这表明SWB是心血管预防的补充方法.
科学领域:
- 心血管疾病的研究研究.
- 精神病学遗传学 精神病学遗传学
- 代谢和血液动力学研究.
背景情况:
- 观察性研究表明,主观幸福感 (SWB) 和心血管 (CV) 事件之间存在反向关系.
- 这种关联的因果关系和潜在途径尚不清楚.
研究的目的:
- 使用孟德尔随机化 (MR) 调查SWB和主要不良心血管事件 (MACE) 之间的因果关系.
- 确定SWB和MACE之间的潜在调解途径,包括代谢和血液动力学因素.
主要方法:
- 进行了两样双向门德尔随机化 (MR) 分析.
- 来自欧洲人群全基因组关联研究的SWB (N=2,370,390) 和MACE (N=500,348) 的遗传仪器被利用.
- 进行了多变量MR和两步MR分析,以调整混因子并确定调解因子.
主要成果:
- 基因预测较高的SWB与39%降低MACE的几率有关 (OR=0.61,P=5.82×10−7).
- 在调整各种医疗状况后,这种关联仍然存在.
- 身体质量指数,腹筋血压和甘油三被确定为重要的调解剂,解释了部分SWB-MACE效应.
结论:
- 较高的SWB因果关系与较低的MACE风险有关.
- 代谢和血液动力学途径,包括BMI,腹压和甘油三,部分介导这种保护作用.
- 加强SWB可以成为预防心血管疾病的传统策略的宝贵补充.
