由于太阳活动和相关的地磁扰动调节自主神经系统的活动，我们假设这些事件将与血压（BP）。我们研究了675名来自规范性老龄化研究（波士顿，MA）的老年男性，在2000年至2017年期间测量了1949次BP。使用混合效应回归模型研究平均1天（即血压测量日）与28天行星际磁场强度、太阳黑子数和全球地磁活动（Kp指数）的二分测量值（以4天为增量）与舒张压和收缩压的相关性。我们调整了气象条件和其他与BP相关的协变量，并在其他模型中调整了环境空气污染物（空气动力学直径≤2.5 µm的颗粒物，炭黑和颗粒数）和环境颗粒放射性。有行星际磁场，太阳黑子数，Kp指数和BP之间的正相关，这些曝光平均超过16至28天BP测量前最大。16天行星际磁场和太阳黑子数量的四分位距增加以及更高的Kp指数与2.5（95% CI，1.7 - 3.2），2.8（95% CI，2.1 - 3.4）和1.7（95% CI，0.8 - 2.5）mmHg分别增加舒张压以及2.1收缩压分别升高2.7（95% CI，0.7 ~ 3.6）、2.7（95% CI，1.5 ~ 4.0）和0.4（95% CI，−1.2 ~ 2.1）mm Hg。在对环境空气污染物和环境粒子放射性进行调整后，相关性仍然存在。太阳活动和太阳驱动的地磁扰动与BP呈正相关，表明这些自然现象影响老年男性的BP。
Since solar activity and related geomagnetic disturbances modulate autonomic nervous system activity, we hypothesized that these events would be associated with blood pressure (BP). We studied 675 elderly men from the Normative Aging Study (Boston, MA) with 1949 BP measurements between 2000 and 2017. Mixed‐effects regression models were used to investigate the association of average 1‐day (ie, day of BP measurement) to 28‐day interplanetary magnetic field intensity, sunspot number, and a dichotomized measure of global geomagnetic activity (Kp index) in 4‐day increments with diastolic and systolic BP. We adjusted for meteorological conditions and other covariates associated with BP, and in additional models adjusted for ambient air pollutants (particulate matter with an aerodynamic diameter ≤2.5 µm, black carbon, and particle number) and ambient particle radioactivity. There were positive associations between interplanetary magnetic field, sunspot number, and Kp index and BP that were greatest with these exposures averaged over 16 through 28 days before BP measurement. An interquartile range increase of 16‐day interplanetary magnetic field and sunspot number and higher Kp index were associated with a 2.5 (95% CI, 1.7‒3.2), 2.8 (95% CI, 2.1‒3.4), and 1.7 (95% CI, 0.8‒2.5) mm Hg increase, respectively, for diastolic BP as well as a 2.1 (95% CI, 0.7‒3.6), 2.7 (95% CI, 1.5‒4.0), and 0.4 (95% CI, −1.2 to 2.1) mm Hg increase, respectively, for systolic BP. Associations remained after adjustment for ambient air pollutants and ambient particle radioactivity. Solar activity and solar‐driven geomagnetic disturbances were positively associated with BP, suggesting that these natural phenomena influence BP in elderly men.
