Body mass index of Russian schoolchildren in the second decade of the XXI century

Abstract

The aim of the study is to establish a trend in the body mass index of schoolchildren in different regions of the country. The study was carried out in 2021 as part of the all-Russian monitoring of the physical development of schoolchildren aged 7–17 years (the number of boys - 30,965, the number of girls - 33,290). The statistical software package Statistica 13 PL has been used for data processing. BMI indicators have been established for Russian schoolchildren. Some regional differences in BMI indicators and the influence of the organization of medical support factor in the region have been shown. The Pearson correlation coefficients between the BMI of schoolchildren and the availability of doctors and nurses per 10,000 of population were -0.63 and -0.39 (p ≤ 0.05). The age and gender standards for BMI for Russian schoolchildren have been updated. A trend towards higher BMI rates in various subjects of the Russian Federation has been revealed, which may be due, among other things, to indicators characterizing the organization of the medical population in the region.

“…Масса тела, длина тела, окружность грудной клетки и талии -наиболее часто измеряемые показатели физического развития [18]. В последние 20-30 лет непременным компонентом оценки физического развития стал расчетный индекс массы тела Кеттле-2 (отношение массы тела к квадрату его длины), который отражает метаболический статус организма и указывает, в случае его отклонения от нормальных значений, на наличие избыточного веса или дефицита массы тела [20]. В обоих случаях, такие отклонения являются указанием на необходимость проведения лечебно-оздоровительных мероприятий [15].…”
