摘要
目前国内外尚缺乏新生儿及婴幼儿的骨密度正常值,更缺乏用骨密度的方法来观察新生儿及婴幼儿骨骼发育及疾病的报道.本文采用单光子骨密度仪测定了110例正常孕母尺桡骨及其新生儿的胫腓骨骨密度,同时还测定了部分早产儿的骨密度,对母孕期营养供给、补钙、日晒、运动等多种因素对其所生新生儿骨密度的影响也进行了多因素分析,结果表明早产双胎儿骨密度值明显低于足月正常新生儿,母孕期适当补充钙剂对母婴的骨密度均有明显影响,母孕期未加服钙剂者母亲的尺桡骨骨密度值明显低于服用钙剂者,她们所生新生儿的骨密度亦明显降低,多因素进步回归分析也发现母孕期的营养供给对新生儿有正性影响,所以提倡孕期保健、适当服用一些钙剂与鱼肝油,加强孕期营养是促进新生儿生长发育的有力保障.
At present there are not normal bone miner density (BMD) values of newborns and infants in our country, and there are. also lack of reports by measuring BMD to observe the bone development and bone diseases in newborns and infants. We have examined BMD of 110 of normal pregnant women and their newborns respectively and 20 of preterm infants or twins with single - photon absorptiometry which may be possessed in general hospital. We have made multiple factor analysis about effects of pregnant women's nutrition-given, oral tablet calcium ,exercise, and sloarization on their newborn's BMD. The results showed preterm infants and twins's BMD values were obviously lower than that of normal newborns. A preper dosage calcium would be benifi-cial for pregnant women and their newborn's BMD. If pregnant women did not be given tablet calcium, the BMD values of the mothers and their newborns were obviously lower than that of given tablet calcium. The multiple stepwise regression also showed that the nutrition-given in pregnant women had a positive effect on BMD of their newborns. So advocation pregnancy hygiene, giving a proper dosage calcium and VitD, enhancing pre-gancy nutrition are beneficial for newborn development.
