Research output: Contribution to journalArticlepeer-review


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<0.01) inverse correlation between the PIH index and monthly geomagnetic activity level was shown. Moderately significant (p<0.05) correlation with monthly maximal (noon hours) gamma-radiowave propagation was evidente as was inverse correlation with this parameter in hours of minimal (early morning) propagation.
