| 摘要 目的：了解 0～3岁婴幼儿的骨密度现状，并分析其相关影响因素，为婴幼儿骨密度不足的预防工作提供依据。方法：选取2016年1月-2018年10月期间于我院进行健康体检的0～3岁婴幼儿860例为研究对象。采用超声骨密度测量仪对入选婴幼儿左腿胫骨中段骨密度进行检测，并对婴幼儿的骨密度现状进行分析。采用问卷调查方式收集所有婴幼儿的性别、年龄、喂养方式、是否补充维生素D、户外活动时间等资料，并采用单因素和多因素Logistic回归分析0～3岁婴幼儿骨密度的影响因素。结果：860例婴幼儿中，骨密度正常婴幼儿336例，轻度骨密度不足婴幼儿196例，中度骨密度不足婴幼儿179例，重度骨密度不足婴幼儿149例，骨密度不足发生率为60.93%。单因素分析结果显示，不同年龄、性别、是否补充维生素D及不同户外活动时间婴幼儿之间的骨密度不足发生率比较差异有统计学意义（P<0.05），而不同喂养方式婴幼儿之间的骨密度不足发生率比较差异无统计学意义（P>0.05）。多因素Logistic回归分析结果显示，年龄（0~6个月，7~12个月）、性别（女）、补充维生素D（否）、户外活动时间（<1 h）为0～3岁婴幼儿骨密度的危险因素（P＜0.05）。结论：0~3岁婴幼儿的骨密度不足发生率较高，年龄、女性、未补充维生素D、户外活动时间过少均是0～3岁婴幼儿骨密度的危险因素，可通过适量补充维生素D、增加户外活动时间以提高婴幼儿骨密度值。 |

| ABSTRACT Objective: To understand the status of bone density in infants aged 0-3 years, and to analyze the related influencing factors, so as to provide basis for the prevention of bone density deficiency of infants. Methods: 860 infants aged 0-3 years who underwent routine health examinations in our hospital from January 2016 to October 2018 were selected as subjects. All infants received the ultrasonic bone density detection in the middle of left leg tibia by the Bone Densitometer. The present situation of bone density in infants was also analyzed. The data of gender, age, feeding methods, vitamin D supplementation and outdoor activity time of all infants were collected by questionnaire. Univariate and multivariate logistic regression were used to analyze the influencing factors of bone density in infants aged 0-3 years. Results: Among 860 infants, there were 336 infants with normal bone density, and 196 infants with mild bone density deficiency, 179 infants with moderate bone density and 149 infants with severe bone density, the incidence of bone density deficiency was 60.93%. Univariate analysis showed that there were significant differences in the incidence of bone density deficiency among infants of different age, gender, vitamin D supplementation and outdoor activities(P<0.05). There was no significant difference in the incidence of bone density deficiency among infants fed with different methods(P>0.05). Multivariate logistic regression analysis showed that age (0-6 months, 7-12 months), gender (female), vitamin D supplementation (no), and outdoor activity time (<1 h) were the risk factors affecting bone density in infants aged 0-3 years(P<0.05). Conclusion: The incidence of bone density deficiency in infants aged 0-3 years is higher. The age, female, no vitamin D supplementation, and too little outdoor activity time were all the risk factors of bone density in infants aged 0-3 years in this area. Adequate vitamin D supplementation and increased outdoor activities can improve the bone density of infants. |
