Preterm birth (PTB) is one of the most important factors that increase the risk of chronic diseases and postpartum death in infants. The aim of this study was to determine the maternal factors that affect the birth of preterm infants in the city of Bandar Abbas.
This is a case-control study that was performed on 400 preterm infants. Sampling was done by a simple method, and information was gathered by interviewing the mothers and their medical records. Data were collected by SPSS software version 16. To compare risk factors in the two groups, conditional logistic regression was used, and < 0.05 was considered statistically significant.
Results showed that factors such as type of delivery (odds ratio [OR] = 3.584, 95% confidence interval [CI]: 1.981-6.485), preeclampsia (OR = 2.688, 95% CI: 1.164-6.207), history of PTB (OR = 4.171, 95% CI: 1.483-11.728), premature rupture of membranes (OR = 3.273, 95% CI: 1.745-6.137), care during prenatal (OR = 0.334, 95% CI: 0.159-0.701), placental abruption (OR = 3.209, 95% CI: 1.209-8.519), placenta previa (OR = 9.333, 95% CI: 2.086-41.770), and cervical insufficiency (OR = 11, 95% CI: 1.381-87.641) were independent risk factors of preterm infant birth.
The PTB risk is higher for women with cervical insufficiency, history of placenta previa, and history of preterm. Early recognition and management of these high-risk conditions among pregnant women may lead to a reduction in PTB rates.
早产是增加婴儿患慢性病风险和产后死亡风险的最重要因素之一。本研究的目的是确定影响阿巴斯港城市早产婴儿出生的母亲因素。
这是一项对400名早产婴儿进行的病例对照研究。采用简单抽样方法，通过访谈母亲及其病历收集信息。数据由SPSS 16软件收集。为比较两组的危险因素，采用条件逻辑回归分析，P<0.05被认为具有统计学意义。
结果显示，分娩方式（比值比[OR]=3.584，95%置信区间[CI]：1.981-6.485）、先兆子痫（OR=2.688，95%CI：1.164-6.207）、早产史（OR=4.171，95%CI：1.483-11.728）、胎膜早破（OR=3.273，95%CI：1.745-6.137）、产前护理（OR=0.334，95%CI：0.159-0.701）、胎盘早剥（OR=3.209，95%CI：1.209-8.519）、前置胎盘（OR=9.333，95%CI：2.086-41.770）和宫颈机能不全（OR=11，95%CI：1.381-87.641）等因素是早产婴儿出生的独立危险因素。
宫颈机能不全、前置胎盘史和早产史的女性早产风险较高。对孕妇这些高危情况的早期识别和管理可能会降低早产率。
