[The use of factor analysis in determining the dietary patterns in the population].

The possibilities of using one of the methods of multivariate statistics, factor analysis, in the study of the frequency of consumption of food categories for the population are considered. Comparison of the results with the results of other statistical methods (cluster and variance analysis) showed the adequacy of factor analysis in the study purposes.

[Benz(a)pyrene antibodies are a marker of carcinogenic load in coal-processing workers].

The authors studied benz(a)pyrene-specific secretory and serum antibody ratios (Ka) in 249 workers of the Kemerovo Power Station, by applying their modified enzyme immunoassay technique. There were 37 (20.5%) and 4 (5.

[Age- and gender-specific features of Kemerovo schoolchildren's health].

The paper presents the results of studying the health status of Kemerovo schoolchildren from the parameters of their physical health and adaptation potential. Characteristic changes in these parameters have been ascertained in different age- and gender-specific groups. Overall, there are progressive decreases in their physical health and functional capacities with age.

[Impact of atmospheric by-product-coking emission on malignancy morbidity].

A statistically significant direct strong correlation was found and an interval was determined between the annual volumes of atmospheric emission from OAO "KOKS" and the standardized (lung, gastric, skin, thyroid, breast, and ovarian) malignancy morbidity rates in Kemerovo. There were gender differences in the incidence of malignancies. The calculated regression coefficients can predict a probable rise in malignancy morbidity in Kemerovo from 2010 due to the increased volumes of atmospheric emission by OAO "KOKS since 2001.

[Ambient air benz[a]pyrene and cancer morbidity in Kemerovo].

A statistically significant direct strong correlation was found between the annual average daily concentrations of air benz[a]pyrene and the lung and the gastric cancer morbidity rates in males and females, skin, thyroid, and ovarian cancer in females. The certain interval of the measured concentration of benz[a]pyrene and the recorded morbidity rate was shown to be characteristic of each of the above-mentioned tumors.
