【目的】对比健康婴幼儿和反复呼吸道感染患儿的骨密度状况,探讨反复呼吸道感染患儿的骨密度测定临床意义。【方法】临床诊断为反复呼吸道感染的婴幼儿91例为病例组,同一时期在儿童保健室进行常规体检的健康婴幼儿96例为对照组,使用超声骨强度检测仪,分别检测上述婴幼儿的骨密度。【结果】病例组骨密度不足明显高于对照组(P<0.05)。【结论】反复呼吸道感染婴幼儿骨密度不足,对其应加强维生素D和钙剂的补充。
【Objective】 To compare the bone mineral density (BMD) in healthy infants and children with recurrent respiratory tract infection and to explore the clinical significance of bone mineral density measurement in children with recurrent respiratory tract infections. 【Methods】 Totally 91 infants and young children with recurrent respiratory tract infection were included in the study. In the same period, 96 healthy infants and young children undergoing regular physical examinations were selected as the control group. Ultrasound bone strength detector was used to detect the infants’ Bone density. 【Results】 The BMD in case group was significantly higher than that in control group (P <0.05). 【Conclusion】 Infants and young children with recurrent respiratory tract infections have insufficient bone mineral density and should be supplemented with vitamin D and calcium supplements.
