Monthly distribution of PIH (Pregnancy Induced Hypertension) was investigated in relation to the number of deliveries and nine specific cosmic and geomagnetic activity parameters during the years 1979-1983. PIH was observed in 3.165% of 19,843 deliveries. Significant (p less than 0.01) inverse correlation between the PIH index and monthly geomagnetic activity level was shown. Moderately significant (p less than 0.05) correlation with monthly maximal (noon hours) gamma-radiowave propagation was evident as was inverse correlation with this parameter in hours of minimal (early morning) propagation.
研究了1979年至1983年期间妊娠高血压（PIH）的月度分布与分娩数量以及九个特定的宇宙和地磁活动参数之间的关系。在19843例分娩中，有3.165%观察到妊娠高血压。结果显示，PIH指数与月度地磁活动水平之间存在显著（p<0.01）负相关。与月度最大（中午时段）伽马无线电波传播存在中度显著（p<0.05）相关性，而在最小（清晨）传播时段与该参数呈负相关。
