【摘要】：目的通过对分娩巨大儿及非巨大儿产妇的多项临床资料分析比较,探讨产生巨大儿的危险因素,为实施早期干预,减少巨大儿的发生风险提供依据。方法选取2014年1月至2015年10月在湖北省妇幼保健院按期产检及分娩的产妇1 793例,对孕妇孕期体重增长等体检指标、妊娠期并发症及新生儿出生结局进行跟踪观察,结合孕前体质指数(BMI)、采用单因素分析和Logistic多因素回归分析方法,分析影响巨大儿发生的危险因素。结果按孕前BMI分组,1 793名孕妇中孕前消瘦者占19.4%,体重正常者占74.3%,超重肥胖者占6.3%。孕期增重低于美国国家科学院(IOM)推荐标准者占16.1%,符合IOM推荐标准者占39.9%,高于IOM推荐标准者占44.0%。妊娠糖尿病发生率9.6%,分娩巨大儿占6.9%。孕前超重肥胖者分娩巨大儿的风险是孕前体重正常者的2.09倍,孕期增重高于IOM推荐标准者分娩巨大儿的风险是符合标准者的2.92倍,男婴为巨大儿的风险是女婴的3.12倍。结论孕前BMI、孕期增重、新生儿性别是发生巨大儿的独立危险因素。控制孕前BMI及孕期增重能有效降低巨大儿的发生率。
[Abstract]:Objective through analysis and comparison of macrosomia and non macrosomia maternal multiple clinical data, to explore the risk factors of macrosomia, for the implementation of early intervention to reduce the risk of macrosomia. Methods provide the basis for maternal 1793 cases from January 2014 to October 2015 in Hubei maternal and child health hospital regular prenatal examination and delivery, for pregnant women weight gain and other medical indicators, pregnancy complications and neonatal outcomes were observed, with pre pregnancy body mass index (BMI), using univariate analysis and Logistic regression analysis method to analyze the impact of risk factors of macrosomia. According to the results of pre pregnancy BMI group, 1793 pregnant women in pregnancy weight weight accounted for 19.4%. Normal accounted for 74.3%, overweight and obesity accounted for 6.3%. weight gain during pregnancy is lower than that of the National Academy of Sciences (IOM) recommended standard accounted for 16.1%, in accordance with the recommendation of IOM accounted for 39.9%, higher than that of I OM standard for 44.0%. gestational diabetes incidence was 9.6%, the risk of macrosomia accounted for 6.9%. pre pregnancy overweight or obesity of macrosomia is 2.09 times the normal risk of pre pregnancy weight, pregnancy weight gain is higher than that of the IOM recommended standard for fetal macrosomia is 2.92 times the standard of the baby for macrosomia risk is 3.12 baby times. Conclusion BMI before pregnancy, weight gain during pregnancy, neonatal sex is an independent risk factor for macrosomia. Control pre pregnancy BMI and weight gain during pregnancy can effectively reduce the incidence of macrosomia.
