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 that affect the birth weight of newborns and provide a scientific basis for health care during pregnancy. Methods A total of 307 pregnant women with single live birth delivered in a hospital in Wuhan City from July 1, 2011 to November 30, 2011 were selected as study subjects. Face-to-face questionnaires were used to investigate the influence of freshmen on generalized linear regression analysis Birth weight factors. Results The birth weight of newborn infants was higher than that of female infants (β = 101.046, P <0.01). The hair loss during pregnancy and prenatal morbidity may lead to birth weight loss (β = -371.481, P <0.05; β = -94.053, P <0.01 ). An increase in mother’s prenatal body mass index and a small amount of mother’s pre-pregnancy alcohol intake may result in increased birth weight (β = 20.020, P <0.01; β = 357.844, P <0.05). Conclusion Neonatal sex, mother’s pregnancy, hair loss, pregnancy status, prenatal body mass index and alcohol consumption are the influencing factors of newborn’s birth weight.
