ABSTRACT

Currently, in the epidemiology of nutrition, methodological approaches to the empirical assessment of the diets of the population and their relationship to health indicators are actively using. In Russia, these approaches have been used in a number of cohort and regional studies, however, such studies are not available for the entire Russian population. Aim. Identification of empirical dietary patterns in the Russian population and analysis of their associations with risk factors for chronic non-communicable diseases. Material and methods. The work was carried out as part of a multicenter epidemiological study "Epidemiology of cardiovascular diseases in the regions of the Russian Federation" (ECVD-RF) in 2013-2014. The final sample size was 19 520 people aged 25- 64 years. Arterial hypertension, general and abdominal obesity, hypercholesterolemia, hypertriglyceridemia, low HDL, high LDL, and hyperglycemia were observed as risk factors for chronic non-infectious diseases. The data on the frequency of consumption of 13 food groups, which were grouped into 10 groups by combining dairy products into one were collected by interviewing. The identification of dietary patterns and assessment of their sustainability was performed using factor analysis (principal component analysis). In accordance with the individual commitment of the participants to the selected dietary patterns the sample was grouped into quartiles for each of the patterns. In order to ensure associations between patterns commitment and risk factors, a logistic regression analysis was used adjusted for the socio-demographic characteristics of the participants. Results and discussion. Four stable dietary patterns with a total specific gravity of the explained variance of 55.9% were identified and conventionally designated as "Reasonable" (milk, sweets and confectionery, fresh fruits and vegetables, cereals and pasta), "Salt" (sausages, pickles and pickled products), "Meat" (meat, fish and seafood, poultry meat) and "Mixed" (beans, pickles and pickled products, fish and seafood). The set of products of the "Reasonable" patterns mainly corresponds to the "Healthy" or "Balanced" patterns in foreign studies, the combination of the "Salt" and "Meat" patterns - the "Western Salt". Adherence to a "Reasonable" pattern was associated with a decrease in the likelihood of risk factors for chronic non-communicable diseases, and to a "Salt" and "Meat" patterns, on the contrary, with an increase. The associations obtained generally correspond to the results of similar foreign studies. A "Mixed" dietary pattern was associated with a few risk factors, which did not allow an unambiguous assessment of the pattern in terms of its impact on health. Conclusion. The study identified empirical dietary patterns of the Russian population and characterized them in terms of associations with the state of health of risk factors for chronic non-communicable diseases.

ABSTRACT

Modeling is the common approach for predicting not only the population health, but also the social and economic burden of disease, which is an important argument while making decisions in health care and prevention. AIM: To develop the model for predicting cardiovascular risk, applicable for the assessment of clinical and socio-economic effects of preventive and therapeutic actions at the level of the whole population or part (region, city, group of patients). MATERIAL AND METHODS: An analytical model for making decision was performed by using a Markov model consisting of Markov states and probabilities of transition from one state to another within a certain time interval. The model included risk factors and cardiovascular diseases (blood pressure, cholesterol, smoking) and probabilities of transition between them. Data was standardized by age for both males and females. Multivariate sensitivity analysis was performed. The literature search conducted using eLIBRARY.RU (http://elibrary.ru) and CyberLeninka (http://cyberleninka.ru). Consultations with experts in the field of coronary heart disease, stroke, heart failure were carried out. RESULTS: The model, allowing to compare the outcomes of two scenarios (absence/presence of intervention). The model included risk factors: arterial hypertension, smoking, hypercholesterolemia, and important CVD: coronary artery disease, myocardial infarction, unstable angina, heart failure, chronic heart failure after myocardial infarction, transient ischemic attack, stroke, atrial fibrillation. There was absorbent state - death. At the output from the model the patient state was defined as the sum of the Markov states characteristics during the model time horizon. Each result had the cost and outcome, which values could be calculated by simulation modeling ("cohort simulation"). The data analysis from prospective study had shown that mortality increases with age, as expected, but in different age groups impact of cardiovascular causes was different and declined with age. In the case of the blood pressure there was the expected increase of the death risk with the growth of pressure levels, both for males and females, except for males 60-64 years old who had a minimal risk of death at the blood pressure 140-149/90-99 mmHg, and among males with normal blood pressure the risk was higher. Smoking was associated with an expected increase of the death risk among all age groups in both sexes. In males, aged 40-64 years, the death risk was higher at the normal levels of cholesterol (2-5 mmol/l), than at the cholesterol levels equal 5-7 mmol/l. There were no data sources to assess probability of occurrence of the risk factors (hypertension, smoking, hypercholesterolemia) in patients who did not have these factors previously in our studies, and available literature. This requires the prospective studies on at least two slices of surveys (not just with the endpoint analysis). Analysis of the literature on search of prospective Russian studies that would evaluate the probability of transition from one state to another, and consultations with experts have identified that currently conducted studies do not provide all the necessary probability of transition on the basis of national data. In the absence of local data for the model is acceptable to use the results of meta-analyzes of international studies. CONCLUSION: Markov model will allow for prediction the effectiveness of different interventions, including their socio-economic consequences. The created model will allow in the future to make changes with the appearance of the results of new studies or new data in order to improve modeling accuracy.

ABSTRACT

AIM: To study the prevalence of anxiety and depression by psychometric methods (the Hospital Anxiety and Depression Scale (HADS) in different regions of the Russian Federation (RF), which are characterized by various climatic, geographic, economic, and demographic indicators. SUBJECTS AND METHODS: The investigation used the data of the multicenter epidemiological survey of cardiovascular diseases in different regions of the Russian Federation--the ESSE-RF study. The subjects of the study were representative samples from unorganized male and female populations aged 25-64 years from 10 RF regions. The survey included a total 16,877 people (6244 men and 10,623 women). All the examinees were interviewed using a standard questionnaire. An analysis involved their gender, age, education level, place and region of residence, and income and morbidity level. The HADS validated in Russia was used to rate the level of anxiety/depression. RESULTS: The total prevalence of higher anxiety and depression averaged 46.3 and 25.6%, respectively. Respondents with clinical anxiety/depression constituted more than one third of those who had a higher level of these conditions. In the examined population, the moderate level of anxiety/depression was 7.5 ± 0.06 and 5.1 ± 0.04, respectively. The population of Volgograd, Samara, Saint Petersburg, and Tomsk had the similar values of the moderate level of anxiety/depression (p > 0.05). The lowest level of anxiety/ depression (p < 0.0001) was seen in the dwellers of Tyumen (5.9 ± 0.1 and 3.4 ± 0.1, respectively) and the highest in the Republic of North Ossetia-Alania (NOA) (8.4 ± 0.1 and 6.8 ± 0.1, respectively). These regions showed the lowest and highest prevalence of higher anxiety (22% in Tyumen and 59.8% in the Republic of NOA (p < 0.0001). CONCLUSION: All the 10 selected RF regions differing in demographic, economic, climatic, and geographical parameters are characterized by a high level of anxiety that remains statistically significant after adjusting for gender and age, so are parameters, such as income and morbidity levels are present in only 4 of the 10 regions.

ABSTRACT

AIM: To compare clinical efficacy of standard outpatient follow-up of hypertensive patients with efficacy of such follow-up with application of internet techniques and mobile telephone systems (ITMTS). MATERIAL AND METHODS: Two groups of hypertensive patients were examined: group 1 (n=97, 45% females, age 49 +/- 11 years) on one-year ITMTS follow-up; group 2 (n=102, 50% females, age 51 +/- 11 years) on standard one-year follow-up. Clinical efficacy was assessed by the rate of achievement and maintenance of target blood pressure, dynamics of modifiable risk factors (smoking, obesity) for a year. RESULTS: Withdrawal in group 1 was 36%, target blood pressure was achieved in 77% patients vs. 12% in group 2 (p < 0.001). CONCLUSION: Introduction of ITMTS technologies into outpatient clinics activity considerably raises efficacy of outpatient treatment of hypertensive patients.

ABSTRACT

Data of 5-year prospective follow-up were used for assessment of clinical course, prognosis and effectiveness of drug and nondrug treatment of 202 patients with ischemic heart disease, occlusive coronary artery atherosclerosis and preserved left ventricular function. It was found that 5-year cardiovascular mortality and rate of nonfatal myocardial infarction did not differ significantly between groups of patients subjected to drug treatment only, transluminal balloon angioplasty, and coronary artery bypass grafting.

ABSTRACT

AIM: To study a course and prognosis of ischemic heart disease (IHD) with stable angina pectoris (SAP) caused by stenotic coronary atherosclerosis (SCA) by 20-year follow-up data. MATERIAL AND DATA: Prognosis of survival was made in 318 patients with SAP due to SCA. RESULTS: The results of a 20-year study show that prognosis in IHD patients depends on SAP severity (by the functional class), exercise tolerance (by the exercise test), severity of coronary bed affection and of left ventricular contractility affection as assessed by coronary- and ventriculography. If lethality of the test subjects was not higher than in the population, the patient had good prognosis associated with one-vessel lesion, normal myocardial contractile function, high exercise tolerance, absence of the leading risk factors. CONCLUSION: The multivariance analysis with stepwise selection enabled the design of the model of the integral prognostic index (IPI) for the studied patients. The IPI index under 1.86 suggests a favourable prognosis, 1.87-2.33--an intermediate prognosis and in IPI higher than 2.34--unfavourable prognosis. Early surgery is recommended for patients with high IPI.
