Increasing research into heliobiology and related fields has revealed a myriad of potential relationships between space weather factors and terrestrial biology. Additionally, many studies have indicated cyclicity in incidence of various diseases along with many aspects of cardiovascular function. The current study examined annual mortality associated with hypertensive diseases in Canada from 1979 to 2009 for periodicities and linear relationships with a range of heliophysical parameters. Analyses indicated a number of significant lagged correlations between space weather and hypertensive mortality, with solar wind plasma beta identified as the likely source of these relationships. Similar periodicities were observed for geomagnetic activity and hypertensive mortality. A significant rhythm was revealed for hypertensive mortality centered on a 9.6-year cycle length, while geomagnetic activity was fit with a 10.1-year cycle. Cross-correlograms of mortality with space weather demonstrated a 10.67-year periodicity coinciding with the average 10.6-year solar cycle length for the time period examined. Further quantification and potential implications are discussed.
对日地生物学及相关领域的研究不断增加，揭示了空间天气因素与地球生物学之间无数潜在的关系。此外，许多研究表明，各种疾病的发病率以及心血管功能的许多方面都存在周期性。本研究调查了1979年至2009年加拿大高血压疾病相关的年度死亡率，以研究其与一系列日地物理参数的周期性和线性关系。分析表明，空间天气与高血压死亡率之间存在一些显著的滞后相关性，太阳风等离子体β被确定为这些关系的可能来源。地磁活动和高血压死亡率也观察到类似的周期性。高血压死亡率呈现出以9.6年周期长度为中心的显著节律，而地磁活动拟合为10.1年周期。死亡率与空间天气的互相关图显示出10.67年的周期性，与所研究时间段的平均10.6年太阳周期长度一致。本文还讨论了进一步的量化分析和潜在影响。
