【摘要】 目的了解学龄前儿童骨强度情况,探讨影响儿童骨强度的相关因素。方法用定量超声骨强度仪测定978名学龄前儿童胫骨骨强度并进行相关因素的问卷调查。结果 0~6岁儿童骨强度随年龄增加呈非线性增加;骨强度不足的4岁以内的检出率随年龄的增长逐渐降低,4岁以后又呈上升趋势;学前儿童骨强度与牛奶、维生素D、钙、每日日晒时间有关。结论 0~6岁儿童是骨强度快速增长期,但骨强度不足的检出率较高,各种因素对其影响较大,应加强儿童骨强度的早期干预。更多还原

【Abstract】 Objective To understand the conditions of bone strength in preschoolers and discuss relevant factors influencing children′ s bone strength.Methods Quantitative ultrasound was applied to measure the tibial strength of 978 preschoolers and questionnaire on relevant factors was completed.Results The bone strength of 0-6 years old children increased with the age in a non-linear way.The detection rate of insufficient bone strength in children younger than 4years old gradually reduced with the growth of age,and the trend became increasing after 4 years old.Bone strength in preschoolers was correlated with milk,vitamin D,calcium and time of daily exposure to sunlight.Conclusion 0-6 years old is the fast growing period of bond strength,but the detection rate of insufficient bone strength is relatively higher,which is greatly influenced by various factors.The early intervention of children′s bone strength should be strengthened.更多还原
