目的探讨母亲既往生育史与早产儿发生的相关性。方法选取2013年2~6月在某医院产科分娩的175例单胎活产早产儿的产妇相关病历资料进行回顾性分析,同时随机抽取同期住院足月单胎新生儿403人作为对照组,应用非条件Logistic回归分析的方法探讨母亲既往生育史与早产的关系。结果母亲既往有过妊娠史且为多次妊娠史是早产儿发生的独立危险因素,并且分别是早期早产和轻型早产的危险因素;母亲既往有自然流产史是早产发生的独立危险因素,且主要是早期早产的危险因素,且随着自然流产次数的增多,早期早产的风险明显增高;当既往人流≥3次时,是早产儿发生的独立危险因素,并且是轻型早产的危险因素;既往有过早产史是再次早产儿发生的独立危险因素,且主要是发生早期早产的危险因素。结论既往多次妊娠史、多次人流史、自然流产史、早产史均是早产的危险因素,并且多数可以导致早期早产,对于合并以上危险因素的孕龄期妇女,加强孕前、孕期宣教及保健工作,可以降低早产的发生。
Objective To explore the relationship between the history of mother’s previous birth and the occurrence of premature infants. Methods A retrospective analysis was conducted on the maternal-related medical records of 175 singleton live births in obstetric delivery in a hospital from February to June 2013. At the same time, 403 newborns with full-term singleton fetuses at the same period were randomly selected as the control group. Non-conditional Logistic Regression Analysis to Explore the Relationship between Maternal Past Birth History and Premature Birth. Results Maternal past history of pregnancy and multiple pregnancies were independent risk factors for preterm birth and were risk factors for early preterm birth and mild preterm birth respectively. Maternal past history of spontaneous abortion was an independent risk factor for preterm birth and predomi- nantly Is a risk factor for early premature birth, and with the increase of the number of spontaneous abortion, the risk of early preterm birth was significantly increased; when the previous flow ≥ 3 times, it is an independent risk factor for preterm birth and is a risk factor for preterm birth; Premature birth history is an independent risk factor for re-preterm birth and is primarily a risk factor for early premature birth. Conclusions The previous multiple pregnancy history, multiple abortion history, history of spontaneous abortion and premature birth are the risk factors of prematurity, and most of them can lead to early premature delivery. For gestational age women with the above risk factors, prenatal and postnatal mission education and health care Work, can reduce the incidence of premature birth.
