ANALYSIS OF NOMINAL AND ORDINAL DATA USING STATISTICA AND SPSS SOFTWARE
This is the sixth paper of a series of articles where we describe basic principles of statistical data analysis using Statistica and SPSS software for beginners. Step-be-step algorithms for Pearson chi-square test and various tests for qualitative data are presented. The main aim of this paper is to provide basic knowledge on qualitative data analysis with practical examples using popular software. The article complements, but does not substitute specialized literature on biostatistics and clinical epidemiology.

ANALYSIS OF THE PREVALENCE OF LOW PHYSICAL ACTIVITY AMONG ADOLESCENTS OF THE EAST KAZAKHSTAN REGION
Background. Physical inactivity as a risk factor is associated with obesity and the development of chronic non-communicable diseases such as diabetes and cardiovascular pathology. In most countries, cardiovascular diseases hold the leading place in the structure of mortality and are major cause of disability in the working age population. In Kazakhstan, as in all other regions, there is a rejuvenation of this group of diseases that may be associated with an increase in risk factors in the population.

STRATIFYING THE RISK OF ADVERSE CARDIOVASCULAR EVENTS IN ACUTE MYOCARDIAL INFARCTION WITH ST-SEGMENT ELEVATION
Objective: The aim of our study was to evaluate the prognostic role of β-APM in patients for myocardial infarction with segment elevation ST (STEMI).
Materials and Methods: In the present research, carried out the study of β-adrenoreception erythrocyte membranes (β-APM) in 81 patients with myocardial infarction with ST-segment elevation with a different course of the disease. β-adrenoreactivity of organism was determined by the value of β-APM using the diagnostic reagent kit "ARM-agate" (LLC "Agat-Med", Moscow). All patients were div... More

CYTOKINE GENE POLYMORPHISM WITH MYOCARDIAL INFARCTION IN SUBJECTS OF RUSSIAN NATIONALITY
Objective: This article considers the study of the frequency of allelic variants and genotypes of cytokines (TNF-α, IL-10, IL-6) in patients of acute myocardial infarction with segment elevation ST (STEMI) in subjects of Russian nationality.
Materials and Methods: The polymorphism of cytokine genes was examined by restriction analysis of specific areas of the genome amplification products in 41 (69.5%) men and 18 (30.5%) women of Russian nationality. Control group was consisted of 75 healthy subjects (donors of Russian nationality). In all ... More
