The objective: to determine the frequency and impact of risk factors among adolescent children in the countryside on the possibility of arterial hypertension (AH) development and to devise the family doctor recommendations for its prevention. Patients and methods. The cohort study of 214 children at the age of 12–17 years who attend Khotiv educational complex «Secondary school of I–III levels – gymnasium» in Kiev region was implemented in order to identify the elevated numbers of blood pressure (BP) and the impact of risk factors on the development of hypertension in future. The sociological poll about the existing risk factors for cardio-vascular disease, the measurement of height and weight with the following bodymass index (BMI) calculation, the Rufe’s test for evaluating the physical efficiency, the BP measurement in the office, the electrocardiography (ECG), the blood pressure daily monitoring (BPDM) and the ophthalmoscopy were carried out. Results. Pre-hypertension was revealed among 29 children that made 13,6±2,3% of respondents, and arterial hypertension was diagnosed for 25 children that made 11,6±2,2%. Arterial hypertension was detected 2.5 times more often among boys in comparison with girls (8,3±1,9% and 3,3±1,5% accordingly). Most of respondents with arterial hypertension were 141year1old children. The most common complaints of the respondents were sleep disturbance (59,3±3,6%), exertional dyspnea (57,0±3,4%), headache (41,1±3,4%) and rapid fatigue (21,0±2,8%). The following risk factors as sex, hereditary factor for arterial hypertension especially combined with diabetes, myocardial infarction, stroke; smoking of respondents, smoking of parents, overuse of products containing the excess of table salt, insufficient use of vegetables and fruit (less than 200 g/day or no daily usage), the use of energy drinks, inactive way of life, low physical activity, the change of body weight (the overweight and the underweight) were significant. Conclusions. The frequency of arterial hypertension among the examined children who live in the countryside is 11.6%, including 8.3% among boys and 3.3% among girls. The main risk factors of arterial hypertension are the overweight, the underweight, the family history of arterial hypertension, the smoking of parents and physical inactivity of children. It has been found out that the absolute risk of arterial hypertension development in future is 40 per cent higher among the smokers, 10 per cent higher among the children whose parents smoke, 20 per cent higher among the dyspn(o)eic respondents, 20 per cent higher among the underweight children, 30 per cent higher among the overweight children, 30 per cent higher among the children with the changes of the fundus of eye, 20 per cent higher among the children with sinus tachycardia and 40 per cent higher among children with a single supraventricular extrasystole or sinus arrhythmia.
