【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
[Abstract]:Objective: bone strength index can reflect the comprehensive characteristics of bone mineral density and bone quality, understand the present situation of bone strength index of young children, explore the related factors that affect the bone strength index of young children, and find out the favorable factors that affect the development of young children's bone. In the key period of growth and development of young children, it lays a foundation for increasing peak bone mass and provides theoretical reference for related researchers. Subjects and methods: 334 children aged 3-5 years in Yuxin kindergarten in Beijing were tested for calcaneal strength index, height, weight and body composition, and the life habits of children and their parents were investigated by questionnaire. Conclusion: 1. The bone strength index increased with age, and there was no difference between male and female. 2. Regular outdoor activities and at least 30 minutes of outdoor activities per day are beneficial to the improvement of bone strength index of young children. 3. Early physical exercise had a great influence on the bone strength index of young children, but it had little relationship with parents' living habits and mother's bone strength index. 4. The bone strength index had little relation with body shape index and body fat rate, but the development of each age was not balanced. 5. Young children's bone strength index and early development level, dietary habits have little effect on them.
