Dynamics of the Variables of Neonates' Physical Development and Geomagnetic Variables over a Many-Year Period

The study of the dynamics of the variables of physical development of neonates in the first months of life and geomagnetic field fluctuations in the period from 1990 to 2001 demonstrated their complex rhythmic structure. In the studied series of birth weight and the parameters of the 84-h rhythms of daily body weight gain, as well as the parameters of the 84-h rhythms of the K-index, there are ranges of increased spectral density coinciding in frequency. In these intervals (1.1–1.3 and 5–10 years), the temporal behavior of the series of physiological and geomagnetic variables is correlated.
