307例新生儿出生体重影响因素的研究

Study on the factors influencing birth weight of 307 neonates

目的调查影响新生儿出生体重的因素,为孕期保健提供科学依据。方法选择2011年07月01日至2011年11月30日期间在武汉市某医院分娩的单胎活产的307例产妇为研究对象,对其进行面对面问卷调查,用广义线性回归分析探讨影响新生儿出生体重的因素。结果新生儿出生体重男婴高于女婴(β=101.046,P<0.01);孕期染发和孕期患病可能导致出生体重降低(β=-371.481,P<0.05;β=-94.053,P<0.01);母亲产前体质指数增加和母亲孕前少量饮酒可能导致新生儿出生体重增加(β=20.020,P<0.01;β=357.844,P<0.05)。结论新生儿性别、母亲孕期染发、孕期患病情况、产前体质指数和饮酒情况均为新生儿出生体重的影响因素。

Objective To investigate the factors influencing neonatal birth weight,and provide basis for health care during pregnancy.Methods A total of 307 parturients who delivered a live-born singleton infant from July 1st,2011 to November 30 st,2011 in one hospital of Wuhan were selected as study objects,and each of them completed a face to face interview.General linear regression analysis was applied to find factors influencing neonatal birth weight.Results Male newborns were heavier than that of female（β=101.046,P0.01）.Hair coloring and illness during pregnancy could decrease birth weight（β=-371.481,P0.05;β=-94.053,P0.01）.There was positive correlation between antenatal body mass index,small amounts of alcohol drinking before pregnancy with birth weight（β=20.020,P0.01;β=357.844,P0.05）.Conclusions The neonatal sex,hair coloring and illness during pregnancy,antenatal body mass index and alcohol drinking may be the factors influencing neonatal birth weight.
