潍坊地区1176例单胎新生儿出生体重分析

Analysis of Birth Weight of 1176 Cases Single Fetal Newborn in Weifang

目的 探讨潍坊地区新生儿出生体重与性别、孕周、分娩方式及孕母年龄的关系,为围生医学保健工作提供理论依据.方法 收集潍坊医学院附属医院产科出生的单胎新生儿1176例,分别对其出生体重与性别、孕周、分娩方式及孕母年龄的关系等相关因素用SPSS16.0作t检验、F检验分析.结果 ①男婴体重（3.439±0.493）kg ,女婴体重（3.338±0.463）kg;②新生儿出生体重在胎龄42周以前随孕周增加而增加;③新生儿出生体重与孕母的年龄无明显关系;④随着新生儿平均出生体重的增加,剖宫产率也相应增加,剖宫产儿出生体重（3.457±0.538）kg,明显高于经阴分娩儿（3.349±0.418）kg.结论 本调查显示新生儿性别、产妇的孕周是新生儿出生体重的影响因素;产前预测新生儿体重对分娩方式的选择及围生期保健具有指导意义.

Objective To provide a theoretical basis for perinatal health care,the relationship between birth weight anti neonatal gender, the age of pregnant woman, gestational weeks and delivery mode were investigated. Methods 1176 single newborns born in Affiliateat Hospital of weifang medical university were selected. Their birth weight and some related factors were retrospectively analyzed. Results （1） The average male birth weight was （ 3. 439 ±0.493 ） kg, and the average baby birth weight was （ 3. 338 ：± 0.463 ） kg. （2）birth weight of newborn before 42 weeks of gestational age was increased with the gestational age. （3）birth weight of newborn had no significant relationship with age of pregnant woman. （4）with the increase of birth weight it yielded a corresponding increase in cesarean section rate and birth weight of newborn by cesarean section was significantly higher than that by vaginal delivery. Conclusion The survey shows newborn gender, maternal birth weight and gestational age are influential factors for neonatal birth weight. Prenatal prediction of neonatal body weight makes sense for the choice of delivery methods.
