Goal of the first part of the research

Evaluation of the degree of bio-efficiency of the factors of heliogeophysical situation by analyzing the contingence of dynamics of these factors with alterations in the epidemiological data on morbidity and mortality of population in Tomsk for the period of time from 1990 through 2008

1) Medical statistical indicators for the period of time from 1990 through 2008, obtained at Tomsk Regional Analytical Department:

– morbidity of Tomsk population on major disease classes, calculated per 1000 of population for each year of the evaluated period;

– mortality of Tomsk population, calculated per 100 000 of population considering the structure of death causes.

2)Indicators of heliogeophysical situation gathered from the following Internet resourceshttp://spidr.ngdc.noaa.gov,http://sosrff.tsu.ru:

–X-ray radiation(X),

– Wolf numbers(S),

– electromagnetic emission flow in spectral window (F),

–Ap-index of geomagnetic storm(А).

1) In order to eliminate the influence of inhomogenuity of dimensions of the analyzed variables on the comparison results of their dynamics, a standardization of the analyzed values was carried out.

2) Maximal (M) and average (M) values as well as standard deviations (S) of indicators have been calculated during the correspondent years.

3) In order to better visualize time series of the data, the Hemming filter was used for smoothing the indicators.

4) Analysis of the studied indicators was performed usingprincipal component analysis to reduce the number of analyzed variables and to identify common factors and main trends in the change of dynamics of the analyzed variables.

Conclusion and mortality and the three factors of heliogeophysical parameters 1

As result of the study, the impact of parameters of heliogeophysical situation on indicators of morbidity and mortality of population in Tomsk, general factors were singled out from the entire aggregation of health indicators of population, which are accurately correlated with alterations in solar activity indicators as well as the indicators of geomagnetic storm, and namely:

F 3ZS – diseases of respiratory organs and mortality caused by the diseases of respiratory organs, blood circulatory system, accidents, F 4ZS – mortality caused by conditions during the perinatal periodcorrelate with F 1 – cumulative solar activity (r=0,84;r=0,47).

F 1ZS – neoplasms, complications of pregnancy and act of delivery, diseases of digestive organs, mortality caused by neoplasms, congenital developmental anomalities,diseases of digestive organs, endocrine system, hypertensive disease, acute myocardial infarctioncorrelate with F 2 – geomagnetic storm (r= - 0,64).

F 5ZS - infectious diseases, diseases of the endocrine and nervous systems, skin, musculoskeletal system, blood circulatory system, traumas and poisonings, mortality caused by infectious diseases and diseases of urogenital system correlate with F 3 – variations of X-ray radiation(r= - 0,78).

Goal of the second part of the research and mortality and the three factors of heliogeophysical parameters

Evaluation of the impact of geomagnetic storms on the frequency of emergency calls to ambulance during one of the most powerful geomagnetic storms of October – November, 2003

End of October and mortality and the three factors of heliogeophysical parameters— beginning of November, 2003 was rarely “stormy” from the point of view of magnetic situation: outbursts in the Sun turned out to be the most powerful for the entire history of the observational astronomy!

The outburst energy on November 4th, 2003 would be enough to supply electricity to such city as Moscow for 200 million years!

TECHNOLOGY AND MATERIALS OF THE RESEARCH and mortality and the three factors of heliogeophysical parameters

A database was formed containing indicators of solar activity alterations, local geomagnetic storm and number of calls to the ambulance, which were all coordinated according to time.

Conclusion and mortality and the three factors of heliogeophysical parameters2

SUMMARY and mortality and the three factors of heliogeophysical parameters

- We carried out the epidemiological research on the effect of heliogeophysical activity in various timeframes on the basis of the regional data.
- We evaluated the degree of bioeffectiveness of the factors of heliogeophysical setting over one-year periods, taken on the basis of Karhunen-Loeve method and epidemiological data of mortality and morbidity of Tomsk population from 1990 to 2008. The analysis of the effect of changes in solar activity and geomagnetic disturbances on the indicators of mortality and morbidity has shown, that among all the indicators in various nosological classes we can reveal general factors which credibly correlate with major components of variances of characteristic indicators of solar activity and geomagnetic disturbance.
- We determined the features of the degree of effect of heliogeophysical activity over the frequency of emergency calls to the ambulance in Tomsk, with 3-hour intervals for data averaging, during one of the most powerful disturbances of 2003. It was discovered that X-ray flow and geomagnetic disturbance are positively correlated with such classes of diseases as cerebrovascular diseases, arterial hypertension, heart rhythm disturbance andasequence as well as functional nervous system disorders. Herewith, variations of epidemiological indicators are connected both with independent effect of X-ray flow and geomagnetic disturbance and with joint effect of these factors.
