Objective: To analyze regional features of the prevalence of Arterial Hypertension (AH) in the south and north regions of the Republic of Kazakhstan (RK). Design and method: In the current study, people aged from 18 to 69 years, who live in the south and north regions of the RK, were invited to participate: 840 respondents from the Almaty region and 1401 people from the Pavlodar region. The proportion of men in the south and north is 29,4 % and 23,2 %, of women – 70,6 % and 76,8 %. In accordance with the standardized methodology of The World Health Organization, named STEPS, we used the data of instantaneous (cross-sectional) epidemiological multicenter study with identification of risk factors. Results: According to the survey the AH's frequency of the occurrence is 51,8% among the population of the north and 47,7% in the south. We have identified the increase of the occurrence of AH related to the age (from 18–69 in both parts of the country). Among participants older than 60 years it reaches 75,9 % in the north part and respectively 78,5 % of patients of the south parts of the country. The prevalence levels of uncontrolled AH in the north are 34% (the standardized rate – 32,2%). This indicator of uncontrolled AH in the south is 33,4% (the standardized rate is 24,6%). In the north part of the RK an antihypertensive drugs (AHD) is taken by 46,2% patients who suffer from hypertension, in the south part - 43.1%; in the north 23,3% participants use that treatment only during periods of high blood pressure values, in the south – 31.9%; do not use AHD 28% of patients in the noth and 22.1% in the south. Conclusions: The prevalence of AH and uncontrolled AH in the south and north regions of the RK is rather high. Gender features of the prevalence of AH were not taken into consideration. The prevalence of AH in the both regions has increases with age. An adherence to treatment is remained low in the studied regions.
