The prevalence of arterial hypertension in Krasnoyarsky territory: the data from the epidemiology study ESSE-RF

Objective. To estimate the prevalence, awareness, treatment and control of arterial hypertension (HTN) among adult inhabitants of Krasnoyarsky territory based on the data from Russian multicenter epidemiological study ESSE-RF.

Design and methods. The study included 1603 subjects 25 to 64 years old selected by the systemic multistage stratified randomization among urban and rural inhabitants of Krasnoyarsky territory. Office blood pressure (BP) was measured twice by the automatic tonometer “Omron” on the right hand in the sitting position. HTN was defined as systolic BP ≥ 140 mm Hg and/or diastolic BP ≥ 90 mm Hg or self-reported previously elevated BP or use of antihypertensive treatment (HTNT). Treatment efficacy was defined as proportion of achieved target BP among individuals who received HTNT, and BP control was assessed as proportion of achieved target BP level among all hypertensives.

Results. The gender distribution was 653 males (40,7%) and 951 females (58,3%). The median level of systolic BP was 133,4 ± 0,5 mm Hg, diastolic BP— 82,9 ± 0,3 mm Hg. The median prevalence of HTN was estimated at 49,4% and appeared to be higher as compared with average Russian parameter 44% (based on the date of 10 regions from the ESSE-RF study). The median prevalence of HTN was estimated at 56,3% in men and 43,7% in women. The HTN prevalence in rural community was significantly higher as compared with urban community (63,4 ± 2,4 vs. 44,2 ± 1,5%, p < 0,01). The median rate of HTN awareness in Krasnoyarsky territory was 77,9% (average rate in Russia based on the ESSE-RF study results was 73,1%). The median rates of HTNT, treatment efficacy and BP control in Krasnoyarsky territory was estimated at 59,5%, 31,6% and 18,8%, respectively. Target BP level was achieved significantly more often among female, than male hypertensives, except those aged 25–34 years.

Conclusions. Thus, estimated prevalence of HTN in Krasnoyarsky territory is higher than average Russian indices based on the data of ESSE-RF study from 10 regions. The median HTN prevalence among men is higher than in women. The rural inhabitants are more likely to have HTN compared with urban inhabitants. Despite high rates of HTN awareness and HTNT, the treatment efficiency in Krasnoyarsky territory appeared to be lower as compared with average Russian ESSE-RF indices.
