Abstract: Objective To explore the effect on integrated group intervention on the physical development and bone mineral density of small for gestational age infants(SGA). Methods During August 2013 to February 2014,67 SGA from high-risk-infant clinic were divided into intervention group and non intervention group according to the parents' will.In the intervention group,33 cases were treated with integrated group intervention,34 cases in non intervention group were treated with conventional high-risk-infant management,and 20 preterm appropriate for gestational age infants health examined during the same period were randomized.At the correct age 12 months,body weight,length,head circumference and bone density were measured. Results Among SGA intervention group,SGA non intervention group and preterm appropriate for gestational age infants group,differences of body weight,length,head circumference and bone density had statistical significances (P<0.05).Body weight,length and head circumference were decreasd of preterm appropriate for gestational age infants group,SGA intervention group and SGA non intervention group.Bone density was decreased of the SGA non intervention group,preterm appropriate for gestational age infants group and SGA intervention group. Conclusions The mode of integrated group intervention can promote the physical development of SGA,especially body weight to catch up quickly.But in the process of catching up,the problem of SGA bone mineral density deficiency should be paid more attention,and the quantitative ultrasound bone mineral density test is worth to recommend.

摘要： 目的 探讨整合性团体干预模式对小于胎龄儿(SGA)体格发育及骨密度的影响,为提高SGA早期干预效果提供理论依据。方法 选择高危儿门诊SGA患儿67例,根据家长意愿分为干预组和非干预组,干预组33例给予整合性团体干预,非干预组34例只进行常规高危儿管理,随机选择同期体检的早产适于胎龄儿20例做对照,于纠正12月SGA干预组和非干预组、早产适于胎龄儿组进行体重、身长、头围及骨密度检测。结果 纠正12月SGA干预组、非干预组、早产适于胎龄儿组体质量、身长、头围及骨密度差异有统计学意义(P<0.05)。早产适于胎龄儿组体重、身长、头围>SGA干预组>SGA非干预组,SGA非干预组骨密度>早产适于胎龄儿组>SGA干预组。结论 整合性团体干预模式能促进SGA体格发育,尤其是体重追赶较快,在追赶过程中,SGA骨密度不足的问题需引起重视,定量超声骨密度检查值得推荐。
