上海市闵行区低出生体重儿危险因素研究

目的探讨影响上海市闵行区低出生体重儿(LBW)的可能危险因素,为进一步制定低出生体重相关干预政策与对策提供参考依据。方法采用病例对照研究的方法,通过上门访谈的方式进行流行病学问卷调查,使用SPSS18.0建立数据库并完成分析。结果通过单因素Logistic回归分析,发现本次怀孕胎数、母亲被动吸烟、蔬菜摄入频率、水果摄入频率、先兆早产、父亲被动吸烟、环境污染和饲养宠物8个因素与LBW的发生有联系(P<0.05)。将筛选出的8个危险因素作二分类变量Logistic回归分析,最终进入模型的变量为本次怀孕胎数、先兆早产和环境污染3个因素。结论 LBW的发生与孕妇的怀孕情况、行为习惯以及生活环境等多方面因素有关系,应采取针对性的措施有效降低LBW的发生。

Study on Risk Factors of Low Birth Weight in Minhang District of Shanghai

Objective To investigate possible risk factors which have impacts on low birth weight in Minhang District of Shanghai.Methods A case-control study was conducted through household survey.SPSS18.0 was used to establish database and statistical analysis.Results The results of univariate logistic regression analysis showed that LBW was correlated with 8 factors including twins or multiple birth,passive smoking of mothers,vegetable intake,fruit intake,threatened preterm labor,passive smoking of fathers,environmental pollution and keeping pets(P<0.05).All these 8 risk factors of LBW were analyzed using multivariate logistic analysis.As a result,twins or multiple birth,threatened preterm labor and environmental pollution entered the model.Conclusion The incidence of LBW is associated with many kinds of factors,including situation of pregnancy,behavior custom,and living environment.Intended measures against those risk factors could be effective in reducing the incidence of LBW.
