目的探讨早产的相关危险因素,为降低早产的发生率提供理论依据。方法采用病例对照研究,对258例早产产妇和258例足月产妇的临床资料进行调查,采用单因素卡方检验进行单因素分析筛选出早产危险因素;多因素非条件Logistic回归进一步筛选早产的主要危险因素。结果孕妇≥30岁;患有妊高症;胎膜早破;孕期生殖道感染;孕期吸烟或被动吸烟是早产发生的危险因素。结论应指导孕妇避免各种早产的危险因素,并对妊娠期的各种并发症进行积极防治,从而有效地预防早产的发生。
Objective To explore the risk factors associated with premature delivery and provide a theoretical basis for reducing the incidence of preterm birth. Methods A case-control study was conducted to investigate the clinical data of 258 pregnant women with preterm birth and 258 full-term pregnant women. The univariate analysis was used to select the risk factors for preterm birth. The multivariate non-conditional Logistic regression was used to further screen the main preterm birth Risk factors. The results of pregnant women ≥ 30 years old; suffering from pregnancy-induced hypertension; premature rupture of membranes; reproductive tract infections during pregnancy; smoking during pregnancy or passive smoking is a risk factor for preterm birth. Conclusions Pregnant women should be instructed to avoid various risk factors of preterm labor and actively prevent various complications during pregnancy so as to effectively prevent premature birth.
