开放二孩政策实施后二胎妊娠期并发症的危险因素分析

目的 探讨开放二孩政策实施后二胎孕妇妊娠期并发症的危险因素，以期降低不良妊娠结局的发生率。方法 选取2016年11月~2017年4月我院收治的存在妊娠期并发症的二胎孕妇102例设为病例组，另选无妊娠期并发症的二胎孕妇108例设为对照组，收集产妇的一般资料及可能的危险因素，对有妊娠并发症的孕妇资料进行单因素分析和多因素非条件Logistic回归分析。结果 单因素分析结果显示:病例组不良妊娠史、与一胎间隔时间长、无孕前检查及孕期营养指导的发生率较对照组高，差异有统计学意义（P＜0.05）；Logistic回归分析显示:与一胎间隔时间长、无孕前检查及孕期营养指导为二胎妊娠期并发症的危险因素。结论 与一胎间隔时间、孕期营养指导及孕前检查与妊娠期并发症的发生有关。

Analysis of Risk Factors for Second Trimester Complications after Implementation of the Open Two-child Policy

Objective To investigate the risk factors of gestational complications in pregnant women with secondary pregnancy after the implementation of the open two-child policy, with a view to reducing the incidence of adverse pregnancy outcomes.

Information on maternal and possible risk factors, single factor analysis and multivariate unconditional logistic regression analysis of pregnant women with pregnancy complications. Results Single factor analysis showed that the incidence of adverse pregnancy history, long interval between one child, non-pregnancy check and nutrition guidance during pregnancy was higher than that of the control group, the difference was statistically significant (P<0.05); Logistic regression analysis showed : Long interval between one child, no pre-pregnancy check and nutrition guidance during pregnancy are risk factors for complications of second trimester pregnancy.
