Untreated hypertension in Russian 35-69 year olds - a cross-sectional study.

Abstract

BACKGROUND:The Russian Federation has among the highest rates of cardiovascular disease (CVD) in the world and a high rate of untreated hypertension remains an important risk factor. Understanding who is at greatest risk is important to inform approaches to primary prevention. METHODS:2,353 hypertensive 35-69 year olds were selected from a population-based study, Know Your Heart, conducted in Arkhangelsk and Novosibirsk, Russian Federation, 2015-2018. The associations between untreated hypertension and a range of co-variates related to socio-demographics, health, and health behaviours were examined. RESULTS:The age-standardised prevalence of untreated hypertension was 51.1% (95% CI 47.8-54.5) in males, 28.8% (25.4-32.5) in females, and 40.0% (37.5-42.5) overall. The factors associated with untreated hypertension relative to treated hypertension were younger ages, self-rated general health as very good-excellent, not being obese, no history of CVD events, no evidence of diabetes or chronic kidney disease, and not seeing a primary care doctor in the past year as well as problem drinking for women and working full time, lower education, and smoking for men. CONCLUSION:The study found relatively high prevalence of untreated hypertension, especially, in men. Recent initiatives to strengthen primary care provision and implementation of a general health check programme (dispansarisation) are promising, although further studies should evaluate other, potentially more effective strategies tailored to the particular circumstances of this population.
