To analyze the distribution characteristics of mothers with different parities in Hebei Province and their impact on pregnancy outcomes.
Data from 398 111 mothers who delivered in 22 hospitals across 10 cities in Hebei Province were analyzed. Based on previous delivery counts (excluding the current hospitalization), mothers were categorized into three groups:primipara (parity=0), multipara (parity=1), and grand multipara (parity≥2). The distribution characteristics of mothers by parity were analyzed, and the influence of different parities on pregnancy outcomes was assessed using multifactorial logistic regression.
From 2014 to 2022, the average age of mothers in all three groups showed an upward trend, as did the proportion of grand multipara mothers. With the increase in hospital level, the proportion of primipara mothers rose, while the proportions of multipara and grand multipara mothers declined. The proportion of primipara mothers in provincial and municipal hospitals was higher than that in county and township hospitals, where the proportions of multipara and grand multipara mothers were lower. As parity increased, the incidence rates of anemia, placenta previa, placental abruption, preterm birth, cesarean delivery, macrosomia, low Apgar scores, and perinatal mortality also increased. Conversely, the incidence rates of gestational diabetes, gestational hypertension, abnormal fetal position, soft birth canal lacerations, postpartum hemorrhage, and low birth weight exhibited a “U” trend. Using primipara (parity=0) mothers as the reference group, the results of the multifactorial logistic regression analysis indicated that parity≥1 was a risk factor for anemia (OR=1.041, 95%CI: 1.024-1.058), gestational diabetes (OR=1.301, 95% CI: 1.237-1.375), placenta previa (OR=1.565, 95% CI: 1.359-1.802), soft birth canal lacerations (OR=1.394, 95% CI: 1.157-1.681), and macrosomia (OR=1.222, 95%CI: 1.189-1.257). In contrast, it was a protective factor against gestational hypertension (OR=0.677, 95% CI: 0.651-0.703),abnormal fetal position (OR=0.650, 95% CI: 0.617-0.684), cesarean delivery (OR=0.296, 95% CI: 0.290-0.301), and low birth weight (OR=0.872, 95% CI: 0.830-0.917). Parity≥2 was identified as a risk factor for preterm birth (OR=1.470, 95% CI: 1.372-1.575) and postpartum hemorrhage (OR=1.242, 95% CI: 1.086-1.420).
The risk of adverse pregnancy outcomes varies with parity. Targeted prevention of gestational complications and comorbidities should be implemented during prenatal care for mothers of different parities to reduce the risk of adverse maternal and infant outcomes.
