Arterial hypertension epidemiology in Bryansk Region: prevalence, awareness, treatment, and control

Abstract

Aim. To study the dynamics of arterial hypertension (AH) epidemiology in urban and rural population of Bryansk Region, aged 19-64 years. To evaluate AH awareness, treatment, and control in the local healthcare settings. Material and methods. Random representative samples of the urban and rural Bryansk Region population - men and women aged 19-64 years - were selected. The study sample was constructed in three stages: selection of policlinics and central regional hospitals; selection of healthcare catchment areas; and selection of households (flats). At the first stage, a random urban and rural sample of 2345 people (response rate 78%) was examined; at the third stage, a sample of 1909 individuals (response rate >70%) was examined. The data were collected using a unified registration form (140-1/u). The study was performed as a part of the Target Federal Program, Ministry of Health. Results. In rural men and women, AH prevalence was 25,9% and 35,4%, while in their urban peers, it was 30% and 38,6%, respectively. The respective levels of AH awareness in urban and rural participants varied from 87,5% to 90,4%, and from 86,6% to 94,6%. In rural and urban samples, AH treatment percentages were 60,3%-76,8% and 77,5%-82,9%, respectively. Effective blood pressure control was achieved in 14,3%-13,8% and 10,1%-29,8% of rural and urban AH patients, respectively. The most popular antihypertensive medications were ACE inhibitors (59,0%–64,1%), diuretics (34,8%–37,0%), beta-adrenoblockers (12,8%–31,6%), and calcium antagonists (10,5%–12,4%). Conclusion. The urban population of Bryansk Region demonstrated higher levels of AH prevalence, awareness, treatment, and especially control throughout the four-year follow-up period.
