Aim. To study prevalence of arterial hypertension (AH), mean values of systolic and diastolic blood pressure (SBP, DBP), awareness of patients about their disease, medication consumption (MC) and efficacy of treatment in several regions of Russia.Material and methods. Representative selections were made in 9 regions of Russia: men (n=5563), women (n=9737) of 25–64 y.o., studied in 2012–2013 with the response 80%. Systematic stratified multilevel random selection was formed with localilty criteria (Kisch method). The Questionnaire on the presence of AH included: awareness of the patient about his disease, drug intake. BP measurement was performed on the right arm by automatic tonometer Omron in sitting position after 5 minutes resting. The mean value of two measurements was used. BP defined as SBP ≥140 mmHg, DBP ≥90 mmHg, or if the patient had taken antihypertensive therapy. Efficacy of treatment — the part of patients (in %) who reached target BP. Control group — part of patients (in %) with BP <140/90 mmHg. Statistic data calculation was done with computer-based statistic software — SAS with standardising by age stratification of Europe.Results. Mean SBP and DBP were 130,7±0,1 mmHg and 81,6±0,1 mmHg respectively. Prevalence of AH — 44%, higher in men (p<0,001). Prevalence of AH was higher in rural area citizens in men — 51,8% vs 47,5% (р<0,02) and in women — 42,9% vs 40,2% (р<0,05). Awareness was 67,5% in men, 78,9% in women. Medications were taken by 60,9% of women and 39,5% of men. Effectively treated were 53,5% of women and 41,4% of men. With the age the part of effectively treated decreases (p<0,0005). BP is under control only in 1/3 of women and 14,4% of men.Conclusion. The role of AH as one of the main modifiable risk factors of cardiovascular diseases is proved, however it is depressing that the percent of controlled AH is low. BP control is the main task of outpatient surveillance at every local outpatient department, where now less than a half of those affected are being observed.

Participants of the study ESSE-RF-2 and co-authors: Moscow: Konstantinov V. V., Pokrovskaya M.S., Efimova I.A., Sivakova O.V.; Krasnodar: Alekseenko S.N., Gubarev S.V.; Оmsk: Livzan M.A., Grishechkina I.A., Rozhkova M.Yu.; Republic of Karelia: Vezikova N.N., Skopec I. S.; Ryazan: Filippov E.V., Dobrynina N.V., Nikulina N.N., Pereverzeva K.G., Moseychuk K.A.Aim. Evaluate the prevalence, awareness, treatment, and control of hypertension among people aged 25-64 examined in 4 regions of the Russian Federation. Material and methods. Study materials were the representative selections of non-organized male (n=3000) and female (n=3714) inhabitants of aged 25-64 from 4 regions of the Russian Federation (Krasnodar region, Omsk region, Ryazan region, the Republic of Karelia), response rate>80%. Systematic stratified multilevel random election was formed with locality criteria (Kisch method). All the participants were interviewed using the standard questionnaire. The universal epidemiological methods and evaluation criteria were used. The study was approved by the local ethics Committee of National research center for preventive medicine. Participants signed informed consent. Hypertension was defined as an average systolic blood pressure (SBP)≥140 mmHg and/or average diastolic blood pressure (DBP)≥90 mmHg and/or antihypertensive therapy (AHT). The efficacy of treatment was the achievement of the target BP. Control group – patients with BP<140/90 mmHg. Results. Mean SBP and DBP were 128.7±0,3 mmHg and 82.8±0.1 mmHg, respectively, higher BP was detected among male (p80 per min in females increased by 1.7 times the probability of absence of AHT. The prevalence of effectively treated was 49.7% of the participants with hypertension. The associations between ineffective treatment and abdominal obesity, ischemic heart disease (males), age, rural type of settlement, obesity (females) were found. Only 24.9% of patients had control of the hypertension.Conclusion. The prevalence of hypertension in Russian Federation remains high. An important task of the medical community is to identify the disease at an earlier stage of its development, before the appearance of complications. This approach can reduce the period from the onset of high blood pressure to a visit to the doctor.

The growing weight of noncommunicable diseases, primarily cardiovascular diseases (CVDs), is a great threat to the health of population worldwide, worsening the quality of life and reducing life expectancy. Realization of this threat led to initiation of epidemiological study by the Russian Ministry of Health to investigate the prevalence of CVDs and their risk factors, since it is CVDs that specify the high allcause mortality in Russia. In the modern history of epidemiology of non-infectious disease, the Epidemiology of Cardiovascular Diseases and their Risk Factors in Regions of Russian Federation (ESSE-RF) study occupies a special place. This is the largest epidemiological study, which is considered as a continuation of preventive activity in order to obtain unbiased information on epidemiological characteristics of population in Russian regions. To conduct the study, the Research Organizing Committee of ESSE-RF study was created and a protocol was developed. All interested scientists and experts from following three centers took part in the work: National Medical Research Center for Therapy and Preventive Medicine, Almazov National Medical Research Center, National Medical Research Center of Cardiology. The Russian regions were justified and selected for participation. In 2012-2014 ESSE-RF study, 13 following Russian regions took part: Volgograd, Vologda, Voronezh, Ivanovo, Kemerovo, Tyumen Oblasts; Krasnoyarsk and Primorsky Krai; the Republic of North Ossetia (Alania); cities of Orenburg, Samara, St. Petersburg and Tomsk. All participated regions used a single study protocol, while biochemical parameters were determined in Federal centers using the same equipment and reagent kits. The paper presents some of the most interesting results that indicate a change in Russian epidemiological situation over the past few years. After the end of cross-sectional study, a field of priority research areas was formed in each center.Conclusion. Epidemiological studies are the most important scientific tool for assessing the prevalence of diseases, their risk factors, as well as predicting adverse events. Based on the results obtained, healthcare system and medical community determine priorities and develop related strategies (population-based and high-risk strategies). For their implementation, a regulatory and legal framework is being created.

Aim. Evaluation of the prevalence of obesity and association with the risk factors of chronic non-communicable diseases of the inhabitants of selected regions of Russia, by the data from ESSE-RF study.Material and methods. Representative selections investigated, of the inhabitants of 13 regions of Russia, totally 21768 participants, males n=8 304, females n=13 464, age 25-64 y. o., under the circumstances of the study “Epidemiology of cardiovascular diseases (ESSE-RF)”, with response ~80%. Standard questionnaire, consisting 12 modules, was developed based upon adapted international methods. For the risk factors prevalence assessment, the standard epidemiological methods were applied. Body mass (BM) was evaluated in the categories of body mass index (BMI) (Ketle index: BMI — Body mass, kg / height, m²). BM as BMI was evaluated as insufficient (BMI <18,5), normal (18,5≤ BMI ≤24,9), overweight (25,0≤ BMI ≤29,9), obesity grade I (30,0 ≤BMI ≤34,9), obesity grade II (35,0 ≤BMI ≤39,9) and obesity grade III (BMI ≥40,0). Abdominal obesity (AO) was assessed with the criteria: for males waist circumference (WC) ≥102 cm and for females ≥88 cm.Results. Mean BMI value among the participants was 27,6 kg/m², with no gender difference. BMI increases with the age only in women. WC — 87,8 cm ±0,1, among males it was significantly higher than in females (92,9 cm vs 84,1 cm, p<0,001), increasing with age. The prevalence of obesity was higher among females comparing to males: by BMI — 30,8% vs 26,9%, p<0,001; by AO — 38,4% vs 24,3%, p<0,001. The prevalence of obesity in female inhabitants of rural regions was significantly higher comparing to citizens (p<0,001), and in the group of higher education, there was no difference among males wither by BMI (p<0,005), or by AO (p<0,001). There was no clear geographic gradient of the risk factors. The prevalence of obesity increases linearly with the age, in males from 14,3% to 36,3%, p<0,001, and in females from 10,7% to 52,3%, p<0,001. AO was more prevalent in women comparing to men in every of analyzed age group, and with the age this difference gets more profound. In the multifactorial model the associations of risk factors were analyzed, with any type of obesity. Close relation was found for obesity and raised levels of glucose and triglycerides, with alcohol overconsumption. Most significant associations were found for obesity and AH in both genders — OR: 2,71 and 2,52 in men and women, respectively. There was linear increase of AH prevalence with mean SBP and DBP, together with BM.Conclusion. In Russian population, obesity is associated most closely with alcohol overconsumption, increased glucose level, lipid disorders and especially strongly — with systemic hypertension, the factors that increase prevalence with age. Burden of this closely interrelated factors on healthcare system will increase with the portion of elderly inhabitants of the country. State of affairs demand for a complex approach based on the governmental politics on the control of populational levels of bodyweight, beginning at elementary school, with mass-media involvement, as the groceries manufacturers, regional governments.

Aim. To study the epidemiological characteristics and changes of hypertension (HTN), as well as factors associated with HTN in the Russian population aged 35-74 years.Material and methods. The Epidemiology of Cardiovascular Diseases and their Risk Factors in Regions of Russian Federation-3 (ESSE-RF3) study examined a representative sample of the population aged 35-74 years of 15 Russian regions with a response >70% (n=28611). Modular design questionnaire was used. Blood pressure (BP) was measured twice after a 5-minute rest in a sitting position on the right arm with an Omron blood pressure monitor. There were following criteria for hypertension: systolic blood pressure (SBP) ≥140 mm Hg and/or diastolic blood pressure (DBP) ≥90 mm Hg, and/or antihypertensive therapy. The effectiveness of treatment was considered the proportion (%) of people who achieved target blood pressure values among those being treated, while the control was considered the proportion (%) of patients with a BP <140/90 mm Hg of the total number of hypertensive patients. HTN changes were studied in a single age range of 35-64 years with the inclusion of materials from the ESSE-RF (2012-14) and ESSE-RF2 (2017) studies, carried out using the same methodology as ESSE-RF3. Statistical analysis was carried out using the open-source R 3.6.1 environment. Analysis of the association between factors and a binary variable was performed using logistic regression. The significance level for all tested hypotheses was 0,05.Results. According to ESSE-RF3, the average levels of SBP and DBP in the population were 131,9±18,7 and 84,4±10,9 mm Hg, respectively, while the proportion of those with BP ≥140/90 mm Hg — 38,8% (men: 44,8%, women: 33,9%). Prevalence of hypertension was 53,9% (men: 56,0%, women: 52,1%), awareness — 77,7% (men: 71,5%, women: 82,3%), while the treatment received 63,4%, significantly higher among women than among men: 72,3 vs 53,3%. The effectiveness of treatment was 44,0%, higher among women compared to men (48,2 vs 37,4%). In addition, 27,9% of patients have controlled HTN.Conclusion. The problem of controlled HTN in Russia remains unresolved in the 21st century. The following significant sex differences remain: the prevalence of HTN is higher among men, but awareness of the disease, treatment rate and its effectiveness are lower compared to women.

Previous studies have shown significant differences in the health status of the population depending on the place of residence. Despite the ongoing preventive measures, there is no improvement in the epidemiological situation in relation to noncommunicable diseases, including due to unfavorable living conditions. This study is a continuation of the following earlier studies: Epidemiology of Cardiovascular Diseases in Regions of Russian Federation (ESSE-RF) and ESSE-RF-2.Aim. To assess the prevalence of cardiovascular diseases, various risk factors (RFs) of these diseases and their association in Russian regions with different economic, climate and geographic characteristics to determine the risk profile of the region and develop approaches to targeted prevention programs specific to the regions.Material and methods. The study selected 30 regions representing each federal district of the Russian Federation. The survey of participants is carried out in three stages as follows: survey using an original modular questionnaire; measurements, including anthropometry, hand grip strength test, blood pressure and heart rate assessment; blood sampling, followed by biobanking and laboratory tests.Conclusion. The results obtained will allow deepening knowledge about the RF profile specific to a particular region, evaluating the effectiveness of preventive programs, and planning new ones taking into account regional and socio-demographic characteristics. This will become the basis for a better understanding of the socio-economic burden of noncommunicable diseases and the economic damage of RFs.
