概括

适度至剧烈的体力活动 (MVPA) 显著降低心肌梗塞 (MI) 风险,腰部至部比率作为调解者. 建议每天至少39分钟的MVPA用于最佳的MI预防.

科学领域:

心血管疾病流行病学
行为科学行为科学
遗传学遗传学是一个

背景情况:

行为因素与心肌梗塞 (MI) 的因果关系及其剂量反应关系仍然不清楚.
门德尔随机化 (MR) 提供了一种强有力的方法来调查行为因素和心脏病发作之间的因果关系的遗传证据.
了解这些关联对于制定有效的公共卫生战略和干预措施至关重要.

研究的目的:

评估11个不同的行为因素 (BF) 和心肌梗塞 (MI) 之间的因果关系.
为了确定重要的BF-MI关联的潜在调解途径和剂量反应关系.
使用多变量MR和贝叶斯模型平均值来优先考虑有影响力的BF.

主要方法:

两个样本的孟德尔随机化 (2SMR) 用于评估BF-MI关联.
一种采用贝叶斯模型平均值 (MR-BMA) 的两样多变量MR方法优先考虑了显著的BF.
调解和限制立方线 (RCS) 分析探索了调解途径和剂量反应关系,并进行复制和元分析以验证.

主要成果:

在11个BF中,有3个通过2SMR显示了与MI的显著关联.
中度到剧烈的体力活动 (MVPA) 成为最有影响力的因素 (MIP=0.77),腰比 (WHR) 调解了这种关联.
通过MVPA的1094-2043MET分钟/周观察到最佳的MI风险降低;元分析也表明茶饮的保护作用 (OR=0.991).

结论:

MVPA独立地与降低心脏病发作风险有关,由WHR调解.
建议每天至少服用39分钟的MVPA,以显著降低心脏病发作风险.
茶饮可能是肌痛性心脏病的保护因素,需要进一步调查.

Regression Toward the Mean

Regression Toward the Mean

Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...
