The Impact of Level of Solar Activity on Mortality by Cause in Longtime Period

Publication

Abstract

The aim of this presentation is to show the dependence of the intensity of mortality on the chosen causes of death in the Czech Republic, according to ICD-10, on the solar activity during the increasing and decreasing phases of the solar cycles No.23 and No.24 in the period 1994-2011. We use the methods of multivariate statistical analysis.

The typology of time profiles for the causes of death is identified with the help of cluster analysis using time. The solar activity is represented by the indices R, Kp, F10.7 and Dst, and also by the foF2 height of the F2 layer and TEC.

There are investigated 67 of individual causes of death according to ICD-10 of groups II.Neoplasms, VI.Diseases of the nervous system, IX.Diseases of the circulatory system and XVII.Congenital malformations, deformations and chromosomal abnormalities. The correlation between the intensity of mortality from cardiovascular disease e.g.

I21 (Acute myocardial infarction) and I64 (Brain stroke) and the solar activity parameters is discovered, as well as a stronger dependence on the height of the F2 layer and TEC. It was found congenital defect Q91 (Edwards and Patau syndrom) dependence on these parameters and also cardiovascular congenital defect e.g.

Q20, Q21, Q23, Q25, Q26.
