The paper presents the analysis results of the anthropometric and functional indicators of children between the ages of 7 and 12 years who permanently reside in Surgut. All surveyed schoolchildren (181 persons – 95 boys and 86 girls) were divided by age and sex. The main anthropometric and functional indicators of the cardiovascular system were analyzed. We established that the growth and development of the examined boys and girls corresponded to general biological patterns. It was found that most of the boys have various deviations from normal body weight: the presence of overweight and obesity were recorded in 50 per cent of cases, body weight deficit was determined in 12 per cent of cases. Normal body weight was recorded most often in the group of girls (85 per cent). The stress adaptation mechanisms was characteristic of every third pupil. We found a high percentage of the stress occurrence frequency in all schoolchildren, but girls had it more common than boys. The obtained data once again confirmed the importance of early diagnosis of the cardiovascular system state for determining the organism adaptation level to adverse social and climatic conditions.
