Increased maternal age at the time of pregnancy and labor is believed to have potential complications. To evaluate the effects of maternal age on the mode of delivery among nulliparous women with term pregnancies who underwent labor induction.
In this retrospective cohort study, 313 women with the gestational age of at least ≥37 weeks, were enrolled. They were divided based on their maternal ages as: Group A < 35 years old (y/o) and Group B ≥ 35 y/o patients. Demographic features and other variables (i.e., past medical history, social history, indications and methods of labor induction, causes of cesarean delivery) were recorded from patients' files. Final outcomes were categorized as: primary (i.e., rate of cesarean section: C/S) and (b) secondary (i.e., duration of labor, postpartum complications, neonatal variables). All data were analyzed by the SPSS ver.21 software.
Median and interquartile ranges of gestational age were not significantly different, comparing the two groups ( = 0.415), although these variables were significantly different regarding maternal height among the two groups ( = 0.007). There was a significant relationship between the methods of labor induction among the two groups ( = 0.005). There was a prominent statistical relationship between (a) C/S deliveries and also (b) indications of C/S among the two groups ( = 0.004 and = 0.033, respectively). Univariate logistic regression test revealed maternal age groups, neonatal weight, and history of underlying diseases had significant results ( < 0.05).
Increased maternal age is associated with higher rates of CS among nulliparous women with term pregnancies who underwent labor induction.
孕期及分娩时母亲年龄增加被认为存在潜在并发症。旨在评估母亲年龄对足月妊娠初产妇引产分娩方式的影响。
在这项回顾性队列研究中，纳入了313名孕周至少≥37周的女性。根据母亲年龄将她们分为：A组<35岁及B组≥35岁的患者。从患者病历中记录人口统计学特征和其他变量（即既往病史、社会史、引产指征和方法、剖宫产原因）。最终结局分为：主要结局（即剖宫产率：C/S）和次要结局（即产程、产后并发症、新生儿变量）。所有数据均使用SPSS 21.0软件进行分析。
比较两组时，孕周的中位数和四分位数间距无显著差异（P = 0.415），尽管两组间母亲身高这些变量存在显著差异（P = 0.007）。两组间引产方法存在显著相关性（P = 0.005）。两组间（a）剖宫产分娩以及（b）剖宫产指征存在显著统计学相关性（分别为P = 0.004和P = 0.033）。单因素逻辑回归检验显示母亲年龄组、新生儿体重和基础疾病史有显著结果（P<0.05）。
母亲年龄增加与足月妊娠初产妇引产时剖宫产率较高相关。
