高龄、适龄孕产妇妊娠结局及高龄产妇产后出血的Logistic回归分析

【摘要】目的分析高龄、适龄孕产妇妊娠结局，并进行高龄产妇产后出血的Logistic回归分析，了解高龄产妇产后出血的危险因素。方法选取2020年8月1日-2021年7月31日于天津市中西医结合医院分娩产妇数1081(在我院定期产检、分娩，病例资料完整者)，新生儿1021例。根据孕产妇年龄分组，其中高龄孕产妇182人，其余为适龄孕产妇，根据随机数字法选取185人，与高龄孕产妇进行比较，回顾分析妊娠结局相关指标。同时，根据高龄组有无产后出血分为产后出血组（n=21）、无产后出血组（n=161），收集两组的临床资料，采用多因素Logistic回归分析高龄产妇产后出血的危险因素。结果适龄组的阴道分娩率高于高龄组，脐带异常、妊娠期高血压、妊娠期糖尿病、妊娠合并心脏病、肥胖、子宫肌瘤、内分泌疾病、感染性疾病、产后出血、低钾血症、早产儿发生率均低于高龄组，其静脉血栓风险评分也低于高龄组（P0.05）。182例高龄孕产妇的产后出血发生率为11.54%（21/182）；经多因素Logistic回归分析显示，孕周≥40周、宫缩乏力是高龄孕产妇产后出血的独立危险因素（P0.05）。结论相较于适龄孕产妇，高龄孕产妇的不良妊娠结局发生率较高，且高龄孕产妇产后出血的发生与孕周≥40周、宫缩乏力是密切相关。
