新生儿出生体重影响因素分析

The Analysis of Influence Factors of Fetal Birth Weight

目的探讨影响新生儿出生体重的因素,为孕前及孕期保健服务工作提供依据。方法选择2012年6月～2012年12月期间在衡阳市妇幼保健院住院分娩的183例产妇为研究对象,对其进行一对一问卷调查。采用单因素分析和二分类Logistic回归分析方法探讨影响新生儿出生体重的因素。结果活产儿平均出生体重为3405.3±103.8 g,巨大儿发生率为12%。男婴巨大儿发生率高于女婴,单因素分析显示产妇年龄、婴儿性别、孕周、产前BMI、妊娠高血压症及糖代谢异常与巨大儿有关,而二分类Logistic回归分析显示孕前体质指数(BMI)、妊娠期高血压疾病、糖代谢异常与巨大儿有关。结论年龄、婴儿性别、孕周、产前BMI、妊娠高血压症及糖代谢异常均为新生儿出生体重的影响因素。进一步完善孕前及孕期服务保健工作,对预防巨大儿发生有重要的意义。

Objective Exploring the influence factors of fetal birth weight to provide experiment data and theoretical basis for the pregnant and pregnancy health service work. Methods 183 puerperae who deliveried from June 1,2012 to December 31,2012 in a hospital in Hengyang were selected to receive one-to-one questionnaire to survey. Data were logged by EpiData and processed by SPSS 18.0 software. One-way Chi-square test and Binary-logistic regression were uesd to ex- plore the influence factors of fetal birth weight. Results The average birth weight live births is 3 405.3 ~ 103.8 g. The incidence rate of fetal macrosomia is 12% , and male incidence is higher than that of female. One-way Chi-square test showed that maternal age, baby gender, gestational weeks, progestation body mass index, gestational hypertension and ab- normal glucose metabolism were realated to fetal macrosomia. Binary-logistic regression showed that progestation body mass index, gestational hypertension and abnormal glucose metabolism were related to fetal macrosomia. Conclusion Further improving the pre-pregnact and pregnant health care service are helpful to prevent fetal macrosomia.
