PREVALENCE OF PREHYPERTENSION AND ITS INTERRELATIONS WITH SOCIODEMOGRAPHIC AND CARDIOMETABOLIC RISK FACTORS IN THE LARGE REGION OF EASTERN SIBERIA

Abstract

Objective: The present study estimated the prevalence of prehypertension in the large Eastern Siberian region population and found its interrelations with other cardiovascular risk factors. Design and method: The randomized sample of the Epidemiological Survey of cardiovascular diSEases in different regions of the Russian Federation included a total of 1603 urban and rural people aged 25–64. The study protocol provided the questionnaire, office blood pressure measurement, anthropometry, and biochemical blood analysis for each participant. With logistic regression, we evaluated the interrelations between prehypertension and sociodemographic, behavioral factors, and biochemical parameters. Results: The average prevalence of prehypertension in the region was at 29.1%. A higher prevalence was found in males compared to females (32.5% versus 27.2% respectively). Younger people compared to older also had prehypertension more frequently (41.6% in 25–34 versus 16.5% in 55–64), while older people had a higher prevalence of hypertension (17.5% in 25–34 and 78.0% in 55–64). Urban population had more prehypertensive people compared to rural (30.7% and 24.7% respectively). The significant predictors of prehypertension were higher education, obesity, and hypertriglyceridemia. Conclusions: The prevalence of prehypertension in our region appeared lower than the average over Russia because of a higher percentage of hypertensive people and a lower percentage of optimal blood pressure in the population. The percentage of prehypertension decreased with age. Higher education along with obesity and hypertriglyceridemia increased the risk of prehypertension.
