为了探讨低出生体重儿（ｌｏｗ ｂｉｒｔｈ ｗｅｉｇｈｔ ｉｎｆａｎｔ ＬＢＷＩ）相关因素及防治措施,回顾分析了４１２例ＬＢＷＩ的临床资料。结果表明,早产、双胎、胎儿宫内发育迟缓和胎膜早破是ＬＢＷＩ前４位主要原因。早产ＬＷＢＩ发生率明显高于足月产及过期产生者;双胎ＬＢＷＩ发生率明显高于单胎者增妇ＬＢＷＩ发生率明显高于城市立妇;身高〈１５６ｃｍ的产妇ＬＢＷＩ发生率明显高于身高〉１５６ｃｍ、体重〉５５ｋ

Analysis on the Causes of 412 Cases of Low Birth Weight Infant

Clinical data of 412 cases of low birth weight infant (LBWI) were analyzed for investigating the causes and the prophylactico-thera-peutic measures.It was showed that premature delivery, twin pregnancy,intrauterine growth retardation and premature rupture of fetal membranes were the main causes.The incidence rate of LBWI in premature deliveries was higher than that in mature and postmature diliveries,in twin pregnancy was higher than in monocyesis,in countryside parturients was higher than in city parturients,and in the parturients whose hights were less than 156cm and body weights were less than 55kg was higher than in those whose hights were taller and body weights were heavier. It was concluded that strengthening perinatal care,improving prenatal diagnosis techniques,finding and treating intrauterine growth retardation in time,preventing premature delivery and intensifying systematic care management for high danger risking pregnancy were important ways for reducing the incidence of LBWI.
