目的探讨导致早产的危险因素,为临床提供依据。方法选取2012年1月~2014年1月在该院分娩产妇598例为研究对象,按分娩时机分为早产组(162例)与非早产组(436例),通过单因素分析探讨引起产后出血的危险因素,建立Logistic回归模型进行多因素分析。结果单因素分析结果显示,两组孕妇年龄、孕妇孕前BMI、高龄孕妇、孕检次数、经济水平、贫血、妊娠期高血压疾病、胎膜早破、孕妇羊水过少和前置胎盘差异均有统计学意义(均P<0.05)。多因素Logistic回归分析发现,孕检次数、妊娠期高血压疾病、经济水平、高龄产妇、前置胎盘和羊水过少是导致早产的独立危险因素。结论孕检次数、妊娠期高血压疾病、经济水平、高龄产妇、前置胎盘和孕妇羊水过少是导致早产的独立危险因素。
Objective To explore the risk factors leading to premature delivery and provide the basis for clinical practice. Methods A total of 598 pregnant women were delivered to our hospital from January 2012 to January 2014, and were divided into premature labor group (162 cases) and non-premature labor group (436 cases) according to childbirth timing. The causes of postpartum hemorrhage Risk factors, the establishment of Logistic regression model for multivariate analysis. Results The results of univariate analysis showed that the differences of pregnant women ’s age, pre - pregnancy BMI, pregnant women, number of pregnancy tests, economic level, anemia, gestational hypertension, premature rupture of membranes, oligohydramnios and placenta previa Statistical significance (all P <0.05). Multivariate Logistic regression analysis found that the number of pregnancy tests, gestational hypertension, economic status, advanced age maternal, placenta previa and oligohydramnios were independent risk factors for preterm birth. Conclusion The number of pregnancy tests, gestational hypertension, economic status, advanced maternal age, placenta previa and oligohydramnios in pregnant women are independent risk factors for preterm birth.
