Objective: To analyze the correlation between age and pregnancy-induced hypertension (PIH) in pregnant women from Hebei province in 2016. Methods: A retrospective analysis was conducted by using the clinical data of 64 909 pregnant women, delivering in 22 hospitals in Hebei in 2016. Descriptive statistics was used to describe the general data and pregnancy outcomes of pregnant women, and χ(2) test was used to compare the incidence of PIH in different age groups, and logistic regression analysis was used to analyze the risk factors for PIH. Results: The incidence of PIH was lowest in 20-29 year old women, and increased obviously in those aged<20 and>35 years (P<0.05), and the incidence was positively correlated with age. Logistic regression analysis showed that age, times of pregnancy, number of previous cesarean section and fetus number of current pregnancy were the risk factors for PIH (OR=1.293, 1.153, 1.307, 3.607), while times of deliver and times of prenatal examination were the protective factors (OR=0.655, 0.951). Conclusion: Advanced age pregnancy and young age pregnancy would significantly increase the incidence of PIH. Prenatal care should be strengthened for pregnant women at risk for PIH.
目的： 分析2016年河北省妇女的分娩年龄，以及分娩年龄与妊娠期高血压疾病（PIH）的相关性。 方法： 对2016年河北省22家医院分娩的64 909例产妇的临床资料进行回顾性分析。采用描述性统计方法描述孕妇的一般资料以及妊娠结局，采用趋势χ(2)检验的方法，分析PIH在不同年龄段的患病情况，采用logistic回归分析方法，分析PIH的危险因素。 结果： 2016年河北省高龄妊娠的比例明显升高，20~29岁妇女PIH的患病率最低，<20岁和>35岁患病率均明显增加（P<0.05）。Logistic回归分析显示，年龄、孕次、既往剖宫产次数、本次妊娠胎儿数均是PIH的危险因素（OR=1.293、1.153、1.307、3.607），产次和产检次数为保护因素（OR=0.655、0.951）。 结论： 高龄妊娠和低龄妊娠均可增加PIH的发生，对有患病风险的孕妇应加强产前检查。.
