モンゴル国青少年の身体発育パターンの解析

─経済成長との関連に基づいて─

While Mongolia has shown remarkable economic growth in recent years, few comparisons have been made with other Asian countries and the level of economic growth is not clearly understood. If the period of peak growth speed were identified, we could grasp how fast or slow the economy is growing and investigate the extent of the influence of that economic growth on physical development in terms of the social and daily living situations. However, there are very few reports on the relationship between the physical development of Mongolian youth and the social and economic situation. In this study the wavelet interpolation model was applied to the speed of economic growth in Mongolia to determine the peak speed leading to that growth rate from the secular trends. Then, from a comparison with the economic growth rate in Japan, and a comparison of physical development in Mongolia and Japan, we examined the physical development pattern in Mongolian youth. For the physical growth data, longitudinal data for height and weight from 6 to 17 years old in Mongolia were obtained. The Japanese data used were longitudinal growth data for height and weight from age 6 to 17 obtained from the “Annual Report on the Survey of Physical Fitness and Athletic Ability” published by the Ministry of Education, Culture, Sports, Science and Technology in 2019. The wavelet interpolation model was applied to the longitudinal growth distance values in the data obtained in both countries. Judging from the physical growth patterns in Mongolian youth, the results show that Mongolian youth are slightly taller than Japanese youth and that their rate of physical maturity is slightly slower, indicating that the socioeconomic conditions in Mongolia are still developing. It is likely that Mongolia is in the midst of rapid rapid high economic growth.
