[Supervision of tuberculosis facilities].

The paper presents the current approaches to organizing and supervising tuberculosis at different levels. The present-day conditions for organizational and methodological measures are analyzed, the concept of supervision is defined and its principles and main elements are described.

[Outlooks for promoting antituberculosis care for the Siberian population].

An analysis of the TB situation in three Siberian territories, i.e. the Kemerovo, Omsk and Tomsk Regions, is presented.

[Use of the major components methods in epidemiological studies].

When multifactorial processes are analyzed, it is most rational to use the methods of multidimensional statistical analysis, including the major components methods. This method is rather new in epidemiological surveys. Its advantage is that it may be used to get information that is difficult derived by other ways.

[Informative value of the major component technique in the assessment of the epidemic tuberculosis situation].

The paper describes a method for comprehensive analysis of the epidemic situation which is based on the major component technique. The algorithm proposed for comprehensive assessment is highly effective in the retrospective analysis and in the analysis of the current material which includes a great deal of various characteristics that are at first sight occasionally unrelated. The use of the algorithm is shown by the example of analyzing 19 statistical variables that characterize the epidemic situation and different aspects of the work of a tuberculosis-controlling facility in 30 districts of the Novosibirsk Region in a period of 15 years (1985-1999).

[Dynamics of major constituents of tuberculosis morbidity in the population of Novosibirsk region].

After processing the dynamic series of tuberculosis morbidity in the population of the Novosibirsk region by the smooth component methods, two major constituents were defined in morbidity dynamics. In total, they make up about half the total variability of tuberculosis morbidity. The first constituent is due to socioeconomic causes that are common for the whole region.
