Ethnic characteristics of physical development of mature and elderly male Northerners

Abstract

Introduction. Physical development indicator variables can be used to estimate the population health status. Mature and elderly male residents of Magadan region, Aborigines and Caucasians by origin, were examined to study basic anthropometric indicators.

Materials and methods. This study presented data obtained in the 2022 Evensk and Magadan Reproductive Health pilot project and Kolyma Longevity regional program surveys. The data of medical examination records of one hundred and seven male residents from the district of Evensk and eight hundred ninety-nine from the city of Magadan were assessed. The following anthropometric indicators were put into general database: body length, body mass, waist circumference, and body mass index was also calculated. Age and ethnic criteria were applied to form 6 groups.

Results. The research showed that negative tendencies in physical development were characteristic of both ethnic groups in both regions: all examinees exhibited high percentage of overweight and shorter body length with the incidence growing with increasing age. The higher waist circumference index at older age in Caucasian populations of Magadan indicated subjective abdominal obesity. The ethnicity proved to specify the dynamics of physical development indicators with age: Caucasian examinees, mostly from the city of Magadan, tended to get shorter in body length with an increase in waist circumference and body mass variables. Aboriginals pronouncedly reduced body length with a tendency to a decrease in body mass, body circumference and body mass index.

Conclusion. Age and ethnicity have an influence on somatometric status of northern residents, which should be considered when forming regional standards of physical development. © 2023. This work is licensed under a CC BY 4.0 license.
