Educational status affects the nature of nutrition. Aim. To study the differences in the nutrition pattern of the adult population of the Russian Federation, depending on the educational qualification. Material and methods . The analysis includes the results of a survey of representative samples of male and female population aged 25-64 years (19,520 people, of which 7,329 men and 12,191 women) from 13 regions of the Russian Federation. The nature of the diet was evaluated by the frequency of consumption of the main groups of products and individual eating habits (supplementation, the use of animal fats in cooking). Results. Men of high literacy have higher consumption of raw vegetables and fruits — by 20%, dairy products — by 14%, including cheese — by 15%. There is also a lower consumption of meat and sausage products — by 17%, pickles — by 12% and poultry — by 11%. Less commonly, there is an adding more salt habit — by 18% and the use of animal fats in cooking — by 10%, more often — the consumption of low-fat and non-fat dairy products — by 22%, as well as raw sugar in an amount not exceeding 5% of the daily calorie content — by 21% The level of consumption of red meat, cereals and pasta, legumes, sweets, cottage cheese, sour cream and cream showed no significant differences with men of a different educational status. Women of high educational status more often include vegetables and fruits in their daily diet — by 14%, dairy products — by 18%, including cheese — by 15%. Less often they consume butter — by 12%, as well as foods with a high salt content: meat and sausage products — by 22% and pickles, marinades — by 15%. Russians with “above average” education are less likely to add more salt — by 14% and use animal fats in cooking — by 14%, more often they choose low-fat and nonfat dairy products — by 21%. In the level of consumption of red meat, cereals and pasta, legumes, sour cream and cream, there were no differences. Conclusion. People with a high literacy in the Russian population regardless of gender differences have a more protective diet compared to people with a low educational status.

Electrocardiography (ECG) takes the lead in assessing the prevalence of coronary artery disease (CAD) in the population. ECG disorders, grouped in the Major (certain) and Minor (possible) categories, are prognostic markers of a high risk of cardiovascular diseases and sudden cardiac death. Unified assessing methods of ECG disorders prevalence and their associations with socio-demographic parameters have not previously been made in Russia.Aim. To study the prevalence of ECG parameters of certain and possible coronary artery disease among population of Russia, depending on the socio-demographic characteristics — age, sex, education and place of residence (city or country).Material and methods. We used 17504 ECGs from representative samples of population (25-64 years old), who participated in the epidemiological study “Epidemiology of cardiovascular diseases and their risk factors in the Russian Federation”. The analysis using Minnesota code was carried out among men and women of four age groups, two educational levels, among citizens and countrymen.Results. The highest prevalence was observed in the “Certain” (5,7%) and “Possible signs of CAD” (7,1%) categories, in the “Certain” (3,8%) and “Possible myocardial ischemia” groups (4,9%), the smallest is in the “Rhythm and conduction disorder” (0,7%) and “STT changes in left ventricular hypertrophy” (0,4%) groups. It was shown that the frequency of ECG disorders increases with age, has an sharp increase after 55 years, regardless of sex. In the age dynamics of categories, STT changes and atrial fibrillation have a decrease of gender differences. All groups of ECG disorders are detected more often among men than women, except for STT changes. With an increase in the level of education, the frequency of ECG pathologies decreases, with the exception of the groups of “major” and “minor Q (QS)”, “major rhythm and conduction disorders”. The prevalence of most ECG disorders does not depend on the place of residence. However, signs of major myocardial ischemia in men are more common in country than in the city (3,9% vs. 2,7%, pConclusion. The results confirm the patterns identified earlier. There is a steady association of ECG data with socio-demographic characteristics.
