不同年龄段高龄经产妇妊娠特点及结局分析

An analysis of characteristics and outcomes of pregnancy in senior-aged parturients of different age groups

目的分析不同年龄段高龄经产妇妊娠特点、分娩方式及妊娠结局。方法选取单胎高龄经产妇1045例,年龄35～47岁。按年龄分为三组:A组67例,41～47岁;B组240例,38～40岁;C组738例,35～37岁。回顾性分析高龄经产妇的临床资料,比较三组孕期并发症及分娩结局。结果 A、B组妊娠期高血压疾病发病率高于C组(13.4%、10.0%vs.6.2%)(P<0.05);A组妊娠期糖尿病和子宫肌瘤发生率高于C组(41.8%vs. 23.7%和22.4%vs. 9.8%)(P<0.05)。A组阴道分娩率低于B和C组(26.9%vs.41.2%和46.5%)(P<0.05)。A组新生儿窒息发生率高于C组(3.0%vs. 0.1%)(P<0.05)。结论高龄经产妇随着年龄增加,妊娠期高血压疾病、妊娠期糖尿病和子宫肌瘤的发生率随之升高,自然分娩率下降。对40岁以上经产妇应加强孕期保健和产时监护,保障母婴安全。

Objective To analyze the characteristics and outcomes of pregnancy in the senior-aged parturients of different age groups.Methods A total of 1045 senior-aged parturients was assigned into three groups of A(41 to 47 years old,67 cases),B(38 to 40 years old,240 cases) and C(35 to 37 years old,738 cases).Clinical data were retrospectively analyzed and the pregnancy complications and delivery outcomes were compared among three groups.Results The incidence of hypertensive disorders of pregnancy was higher in groups of A and B than that in group C(13.4% and 10.0% vs.6.2%)(P<0.05). The incidence rates of gestational diabetes mellitus and uterine myoma were higher in group A than those in group C(41.8% vs. 23.7% and 22.4% vs. 9.8%)(P<0.05).The vaginal delivery rate of group A was lower than that of groups of B and C(26.9% vs.41.2% and 46.5%)(P<0.05).The incidence rate of neonatal asphyxia was higher in group A than that in group C(3.0% vs. 0.1%)(P<0.05).Conclusion As the increase in the age of the senior-aged parturients,the incidences of hypertensive disorders of pregnancy and gestational diabetes mellitus as well as hysteromyoma are increased and the vaginal delivery rate is decreased.Attention should be paied to the health care during pregnancy and prenatal care for ensuring the safety of both mothers and infants.
