Objective. The study assessed the incidence of high blood pressure (BP) cases in 10–17-year-old children and adolescents of Magadan through the 10-year period. Design and methods. The author compared the results of the 2009 and 2019 health monitoring surveys which involved 2533 10–17-year-old school children of the city of Magadan. All participants were of Caucasian race, natives of Magadan, without a history of chronic diseases. The data of the assessment of anthropometric and cardiovascular parameters in 2009 and 2019 were compared. Results. The author observed a significant increase in systolic BP (SBP) and diastolic BP (DBP) in both gender groups with the growth of anthropometric indices from 2009 to 2019: boys at ages 12–13 and 17 (SBP) and at 11–17 years old (DBP); girls at ages 11–13 and 15 (SBP), as well as at 11–13 and 16 years old (DBP). Analysis of the rates of high-normal BP (≥ 90th and < 95th percentile), the author found that girls demonstrated high-normal BP in 2009 and 2019 in 6,6 % and 8,6 % of cases, respectively, while boys showed high-normal BP in 10,2 % and 7,3 % of cases in 2009 and 2019, respectively. The incidence of high BP (≥ 95th percentile) was 5,1 % and 7,3 % in girls; 8,0 % and 9,9 % of cases in boys in the studied years. Conclusions. The study shows a significant increase in basic anthropometric indicators as well as SBP and DBP variables for both age specific groups. The incidence of high BP (≥ 95th percentile) was 5,1 % and 7,3 % in girls, and 8,0 % and 9,9 % in boys, respectively. Overall hypertension trends were registered in children and adolescents with BP rates increasing within ten-year period.

Introduction: The prevalence of overweight and obesity among children and adolescents has become a challenge in most countries of the world. Objective: To develop regional standards for the body mass index (BMI) of children and adolescents in the city of Magadan in order to identify groups at risk of these conditions. Materials and methods: We have analyzed data on 4,663 Magadan schoolchildren aged 8–17 involved in the survey conducted in 2009–2019. Based on the main anthropometric parameters of body height and weight, we calculated the body mass index (Quetelet II Height–Weight Index). The centile (nonparametric) method was used to determine healthy and abnormal BMI values. Results: Distribution of body mass indices of the schoolchildren in Magadan by centile ranges of the regional standards showed the prevalence of mean values in 49.8 % of the subjects. BMI values indicating obesity or underweight, i.e. below the 3rd or above the 97th percentile, respectively, were found in 3.1–3.4 % of the examined. An increase in the proportion of overweight and obese children was observed when comparing our data with Russian norms. We established that the mean BMI values of the girls and 8 to 13-year-old boys living in Magadan exceeded the upper limit of the Russian norm (75th percentile) for children and adolescents. At the lower limit of the means (25th percentile), changes were within the range of the means, except for boys aged 16 to 17 years. Conclusion: The use of region-specific BMI standards allows correct and timely identification of underweight and/or overweight/obese schoolchildren in order to carry out appropriate treatment and preventive measures.

Introduction. This study compared body mass index and arterial blood pressure indices in boys and girls born in Magadan from ages eleven to seventeen. Material and methods. A total of 633 girls and 784 boys aged 11-17 were randomly sampled for the examination which was fulfilled in school physician’s offices and in the summer period of June-July, 2018-2019, in a children’s health camp. Body length (BL, cm) and body mass (BM, kg) were measured, and BMI was calculated for each student. A complex of hard & software unit for noninvasive study of central hemodynamics and the method of volumetric compression oscillometry were used to test subjective cardiohemodynamic performance at rest. Results. At the age of 14-17, boys tended to be higher in systolic blood pressure (mmHg) and body mass (kg) than girls (p <0.01, p <0.01). Girls, compared with boys, demonstrated higher average variables of heart rate (p <0.05, p <0.01) and diastolic blood pressure (p <0.01, p <0.001) through all age groups. By analysis of individual values obtained for blood pressure and heart rate, 77.2-70.2% of boys and 80.2-75.1% of girls could be referred to those having normal indices. 11.3% of boys and 10.3% of girls exhibited blood pressure variables close to the upper limit of the norm (high norm), and 11.5% and 9.5% of schoolchildren, respectively, were diagnosed with hypertension. Body weight deficiency or overweight were characteristic of 7.2% and 8.7% of girls, and 4.7% and 6.1% of boys, respectively (p <0.05). Quite similar percentage of children could be considered obese: 2.5% of boys and 2.7% of girls. Conclusion. The most pronounced changes in children’s cardiohemodynamic performance develop in puberty: in girls from ages 11 to 13, in boys at ages 11-14 and 16-17. High incidence of arterial hypertension was observed in both boys and girls at 16-17. A positive correlation between body mass index and blood pressure level existed.
