To analyse maternal factors associated with prematurity in public maternity hospitals.
Retrospective unmatched case-control study on two public maternity hospitals in the State of Acre, Brazil.
A sample of 341 newborn infants of premature birth (< 37 weeks; case group) and 388 newborn infants of term delivery (≥ 37 weeks; control group).
A validated instrument was used for interviews, and information was collected from hospital records. The variables were divided into five blocks: (1) maternal sociodemographic and economic characteristics, (2) maternal biological and reproductive characteristics, (3) maternal habits, (4) pregnancy complications, and (5) neonatal characteristics. The hierarchical analysis was performed using multiple logistic regression.
The risk factors associated with premature birth were as follows: newborn infants of mothers who were born premature (p = 0.005), with low BMI (p = 0.006), history of a previous preterm child (p<0.003), who had stress (p = 0.020) and physical injury during pregnancy (p = 0.025), with quality of prenatal care classified as inadequate II (p = 0.001), which presented abnormal amniotic fluid volume (p<0.001), pre-eclampsia/eclampsia (p<0.001), bleeding (p = 0.013) and hospitalization during pregnancy (p = 0.001).
The variables that were associated with premature birth were mother born preterm, low BMI, previous premature child, stress and physical injury during pregnancy, prenatal care inadequate II, bleeding, abnormal amniotic fluid volume, pre-eclampsia/eclampsia and hospitalization during pregnancy. It is important to properly perform prenatal care, having a multidisciplinary approach as support, with the objective of keep up with changes in nutritional classification and monitoring of adverse clinical conditions.
分析与公立妇产医院早产儿相关的产妇因素。
巴西阿克里州两家公立妇产医院的回顾性非匹配病例对照研究。
共纳入 341 例早产新生儿（<37 周；病例组）和 388 例足月新生儿（≥37 周；对照组）。
使用经过验证的工具进行访谈，并从医院记录中收集信息。将变量分为五个部分：（1）产妇社会人口经济学特征，（2）产妇生物学和生殖特征，（3）产妇习惯，（4）妊娠并发症，（5）新生儿特征。使用多因素逻辑回归进行分层分析。
与早产相关的危险因素包括：母亲为早产儿（p=0.005）、体重指数低（p=0.006）、既往有早产儿童（p<0.003）、孕期有应激（p=0.020）和身体损伤（p=0.025）、产前保健质量差 II 级（p=0.001）、羊水异常（p<0.001）、子痫前期/子痫（p<0.001）、出血（p=0.013）和孕期住院（p=0.001）。
与早产相关的变量包括母亲为早产儿、低体重指数、既往有早产儿童、孕期应激和身体损伤、产前保健质量差 II 级、出血、羊水异常、子痫前期/子痫和孕期住院。重要的是要正确进行产前保健，采取多学科方法提供支持，以保持营养分类的变化，并监测不良临床情况。
