Introduction. Arterial hypertension (AH) is one of the main causes of the cardiovascular diseases (myocardial infarction and heart failure). Arterial hypertension leads to complications such as cerebral insult, myocardial infarction, coronary artery disease, renal dysfunction and heart failure [2]. In our country, AH composes 41.8% of the cardiovascular diseases. 52% of the mortality due to cardiovascular diseases results from AH and its complication – cerebral insults [4]. It is obvious in the world that obesity and overweight as main risk factors of the AH influence negatively on human body and affect health harmfully. There, in our country, some studies have been conducted on prevalence of the AH and obesity. But there is no study that reveals correlation between obesity and arterial hypertension, therefore, the study aimed to study it. Aim. The study aims to establish correlation between arterial hypertension and overweight/obesity among Mongolian people. Materials and Methods: In the study have been involved 3411 people aged of 15-64. Out of them 1674 (49%) were men and 1737 (51%) were women. AH classification was used according to the National Guidelines of the Arterial Hypertension for Mongolian adults. In the study outcome analysis, the statistical program SPSS-12.0 was used for data creating, checking, processing and compiling of the results. Difference in the parameters was evaluated by Chi quadrates. Results: Among people involved in the study, 29.3% had arterial hypertension and 70.7% had normal blood pressure. 18.6% of the total studied people had AH of I degree, 6.2% - AH of II degree and 4.5% - AH of III degree. By regions of AH prevalence, in Ulaanbaatar, AH was 30.2%, in the Western region - 29.4%, in the Khangai region - 28.3%, in the Central region - 28.2%, in the Eastern region - 29.8%. There was no significant difference in AH prevalence for the regions (ℵ2=11.715, p<0.469). For overweight, obesity, by regions, in the Central region and Ulaanbaatar, overweight and obesity rate was higher than in other regions. The highest rate of the overweight, obesity observed in the people aged of 35-44 years (29.7-38.6%) which are most active ages for employment. Conclusions: 1. Arterial hypertension incidence frequency correlated with Body Mass Index. 2. Arterial hypertension incidence becomes more frequent with increase in Body Mass Index. 3. Risk of arterial hypertension is 1.8 more frequent in I degree, 4.2 more frequent in II degree, 19 more frequent III degree of the obesity.
