目的探讨母亲孕期环境相关因素对足月低出生体重儿的影响,为制定相应的保健措施提供依据。方法采用病例对照研究方法,利用问卷对2014年4-8月在重庆市6所妇幼保健院住院分娩的84例足月低出生体重儿和283例正常对照组新生儿的父母进行现场调查,运用χ~2检验和非条件Logistic回归模型进行分析。结果单因素分析结果显示吸烟、被动吸烟、母亲孕期服用多种维生素片、食用蛋类、奶类及其制品、水果类、坚果类、主食摄入情况可能是发生足月低出生体重儿的影响因素。多因素分析结果进一步证实,被动吸烟(OR=1.89)、孕期食用蛋类(OR=0.61)、孕期主食摄入量少于孕前(OR=4.08)是发生足月低出生体重儿的主要影响因素。结论足月低出生体重儿的发生受多方面因素共同作用的影响,应采取综合措施来预防和控制足月低出生体重儿的发生。
Objective To investigate the impact of maternal environmental factors on term low birth weight infants and provide basis for formulating corresponding health care measures. Methods A case-control study was conducted to investigate the parents of 84 full-term low birth weight infants and 283 normal controls neonates who were hospitalized in 6 maternal and child health centers in Chongqing from April to August 2014, χ ~ 2 test and non-conditional logistic regression model. Results The results of univariate analysis showed that intake of smoking, passive smoking, multiple multivitamin tablets for mothers during pregnancy, consumption of eggs, dairy products and their products, fruits, nuts and staple foods may be the impact of full-term low birth weight infants factor. Multivariable analysis further confirmed that passive smoking (OR = 1.89), consumption of eggs during pregnancy (OR = 0.61), lower intake of staple food during pregnancy than before pregnancy (OR = 4.08) were the main influencing factors for term low birth weight infants . Conclusions The incidence of term low birth weight infants is affected by many factors and comprehensive measures should be taken to prevent and control the occurrence of term low birth weight infants.
