摘要
研究目的：骨强度指数能够反映骨密度和骨质量的综合特点,了解幼儿骨强度指数现状,探讨影响幼儿骨强度指数的相关因素,发现影响幼儿骨骼发育的有利因素,在幼儿生长发育的关键时期,为提高峰值骨量奠定基础,为相关的科研工作者提供理论参考。研究对象与方法：对北京市育新幼儿园334名3－5岁幼儿进行跟骨骨强度指数、身高、体重、身体成分的测试,同时通过问卷调查幼儿及其家长的生活习惯。
研究结论：
1.幼儿骨强度指数随年龄增长而增加,男女性别之间无差异。
2.规律的户外活动且坚持每天户外活动时间至少30分钟以上有益于幼儿骨强度指数的提高。
3.母亲早期体育锻炼对幼儿骨强度指数影响较大,但与家长生活习惯及母亲骨强度指数关系不大。
4.幼儿骨强度指数与身体形态指标及体脂率关系不大,各年龄之间发展不平衡。
5.幼儿骨强度指数与早期发育水平、饮食习惯影响不大
AIMS:Bone Strength Index (BSI) can reflect the situation of Bone Mineral Density (BMD) and Bone Quality (BQ). Understanding the status of children's BSI, discussing the relative factors which may affect the BSI, and finding the positive factors to the growth of children's bones are the main targets of this paper which may give suggestions to improve the bone quantity in children's key period of bone growth and to the following research work.
Methods:334children, from Beijing Yuxin Kindergarten and aged from3-5years were recruited. Their height, body mass and body composition were measured, while questionnaires are given to their parents for surveying their daily habits.
Conclusions:
1.The BSI of the children increases along with their aging. There are no differences between the two genders.
2.Regular outdoor activities of30minutes every day can benefit improvements of the BSI.
3. The physical activities of the mothers in their young age affect the BSI of their children.
4. The relationship between the BSI of the children and the fat ratio is not significant according to the statistic analyses. The development of bones is different among different age groups.
5. The BSI has nothing to do with not only the growth quality of the children in their young age, but their eating habits.
