The purpose of this study was to investigate the standardization of height growth curves of 8 ethnic groups in Thailand and Union of Myanmar. The height of 16,000 children from 5 to 18 years old of 8 ethnic groups, i. e., Thai, Karen, Hmong, Lisu, Akha, and Lahu in Thailand, Burmese and Mon in Myanmar, was measured from 1994 to 2004 in Thailand, from 2005 to 2008 in the Myanmar. Modified BTT model was applied to height growth curve, and the fluctuation of standard deviation was smoothed using weighted moving variation and smoothing function developed by the authors. Finally growth charts were obtained using z-score of normal distribution. Resultant growth charts were generally satisfactory and were seemed to be useful from the perspective of data utilization. Though there are a few problems on the growth charts such as variance was decreased for more than 15 years old, or height growth has continued till 18 years old in some ethnic groups. Representing heights were different more than 10 cm among ethnic groups at 18 years of age. It was confirmed that it is important to create a growth chart by ethnic group respectively and utilize it in order to evaluate properly the growth status and the nutritional condition of the children.

The purpose of this study was to examine the bone stiffness of healthy girls during their growth period and factors affecting on such stiffness. The subjects were 302 secondary school girls in Tokyo. Parameters examined included the body characteristics (standing height, body weight, bone stiffness measured by ultrasound, muscle thickness measured with the ultrasound B-mode system), extension power of the lower limb (containing the knee and hip joints), and a questionnaire about the daily intake of milk, kinds of meals and number of years from menophania. These examinations were carried out in June 1997.Results were summarized as follows : 1) From the observation of bone stiffness in secondary school girls, it appears that bone stiffness increases during the junior high school period. In other words, the bone stiffness of the subjects had almost reached on adult level by high school. 2) A significant positive correlation was recognized between chronological age and bone stiffness (r=0.365, p<0.05) . A positive correlation also existed between the years from menophania and bone stiffness (r=0.477, p<0.05) . These coefficients showed that the years from menophania correlate with bone stiffness more closely in comparison with chronological age. 3) In the period when short comparatively years from menophania, body characteristics, which were the index of maturity, correlated to bone stiffness. However, muscle thickness/power, which was related to exercise habit, became the major parameter correlating with bone stiffness. These results suggest that factors affecting bone stiffness should differ according to the growth period. 4) Comparison of different athletic clubs showed that the bone stiffness of volleyball players was higher than that of control. These data suggest that physical education class, which was given 3 times a week, is not enough for total body development in both quality and quantity. In other words, physical education should be better matched with total physical development, including the growth of healthy bones.

本研究の目的は,幼児から中学生の子どもを対象にライフスタイル改善教育及び体力向上プログラムを幼児・学教教育に適用し,同一集団の子どもをそれぞれ縦断的に追跡しながら,その有効性を検証することであった.おもな成果は次の3点であった.1)体力向上プログラムに参加した幼児の体力は,小学校1年で極めて高く,体力A評価は50%を超え,持ち越し効果が確認された.2) 低学年児童を対象に基本的動作習得を目指した8時間の授業で,動作の改善と共に,50m走後半の疾走スピードに有意な改善が見られた.3) 中学校での3年間継続した体力向上への取り組みによって,生徒の遅刻回数や不定愁訴が有意に減少した.
