目的:了解婴儿骨强度现状,探讨影响婴儿骨强度的相关因素。方法:用定量超声仪对1431名婴儿进行骨强度测定并进行相关因素问卷调查,调查资料运用SPSS统计软件进行分析。结果:婴儿骨强度减低占44.2%,以轻度为主,经单因素和多因素分析,性别、年龄、有佝偻病症状和体征、喂养方式与婴儿骨强度相关。结论:婴儿骨强度总体水平偏低,临床应重点关注小年龄女婴,定期监测骨强度,对防治婴儿佝偻病有积极意义。
Objective: To understand the current status of infant bone strength, explore the factors that affect infant strength. Methods: Quantitative ultrasound system was used to measure the bone strength of 1431 infants and related factors were investigated. The survey data were analyzed by SPSS statistical software. Results: The decrease of infant bones strength accounted for 44.2%, which was mainly mild. Univariate and multivariate analysis showed that infant’s bony strength was related to gender, age, symptoms and signs of rickets, and feeding patterns. Conclusion: The overall level of infant bone strength is low, so it is important to pay attention to the infant girl with small age in clinic, and to monitor the bone strength on a regular basis. It is of great significance for the prevention and treatment of infant rickets.
