自发性早产高危因素的分析

摘要

目的 分析引起自发性早产的高危因素.方法 自发性早产孕妇145例为早产组,同期足月自然分娩的孕妇290例为对照组.通过采用单因素、多因素Logistic回归分析,回顾性分析引起自发性早产的高危因素.结果 孕妇孕期发生负性事件、产检次数少、胎膜早破、宫内感染、孕期阴道炎、妊娠期糖尿病、多胎妊娠是引起自发性早产的主要高危因素；孕期增长身体质量指数是自发性早产的主要保护性因素.结论 自发性早产是多方面因素作用的结果.%Objective To analyze the high risk factors of spontaneous preterm labor. Methods Retrospective analysis was made on 145 patients who had spontaneous preterm labor and 290 pregnant women with normal delivery at the same time. The indexes are analyzed by single and multiple factor Logistic regression with SPSS 11.5 software to analyze the high risk factors of spontaneous preterm labor. Results Negative affairs, fewer obstetric examination times, premature rupture of membranes, intrauterine infection, vaginitis during pregnancy, gestational diabetes mellitus (GDM) and multiple pregnancy are the highest risks for spontaneous preterm labor. Gestational BMI increase is the protective factor for spontaneous preterm labor. Conclusion The high risk factors of spontaneous premature labor are complex.
