1431名婴儿超声骨强度测定结果分析

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。

Measurement outcomes of quantitative ultruasound (QUS) bone intensity of 1,431 infants

Objective To explore the present condition of bone indensity and related elements that influence the bone intensity of infants.Methods The bone intensity of 1,431 infants was measured by means of quantitative ultruasound（QUS）followed by questionnaires of related factors,then SPSS statistical software was applied to carry out the analysis of the data.Results The reduction of infant bone intensity accounts for 44.2%.Also,the amount of decrease in some infants is at low level.With the single and multiple fators analysis ,sex,age ,feed patterns,and having the rachitis symptom or not were the important factors that affect the bone intensity in infants. Conclusions The infant bone intensities are mainly in low condition. Clinical experts should lay their emphasis on infants who are reletively younger. Monitoring the bone intensity at regular intervals is significant in prevention and cure of rachitis.
