Prevalence, Awareness, Treatment and Control of Hypertension in Russian Federation (Data of Observational ESSERF-2 Study)

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.;  О msk:  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 80 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.
