OBJECTIVE

Our aim was to analyze the risk factors of hypertensive disorders of pregnancy (HDP) and explore its influence on fetal risk factors, infant's blood cells and markers of inflammation.

METHODS

A total of 123 patients with HDP were in the HDP group, and 121 healthy pregnant women were selected as the control group. The general clinical data of the participants were recorded. Statistics of maternal and infant outcomes, delivery methods, routine blood lab results and coagulation factors of the newborn were recorded. Univariate analysis and multi-factor analysis were used to explore the risk factors for HDP.

RESULTS

The overall incidence of poor maternal outcomes in the HDP group was higher than in the control group. The incidence of premature delivery; postpartum hemorrhage; coagulopathy; placental abruption; heart failure and hemolysis, elevated liver enzymes, and low platelets (HELLP) syndrome was significantly higher in the HDP group than in the control group (P < .05). The cesarean section rate in the HDP group was significantly higher than in the control group (P < .05). The overall incidence of poor outcomes in fetuses and newborns in the HDP group was higher than in the control group. The incidence of infant low birth weight, intraventricular hemorrhage (IVH), neonatal respiratory distress syndrome (NRDS), asphyxia and all-cause neonatal death were higher than in the control group (P < .05). The incidence of small gestational age (SGA), fetal distress and intrauterine death in the HDP group were higher than in the control group (P < .05). In the HDP group, neonatal white blood cells (WBC), neutrophils (NEUT) and platelets (PLT) were significantly lower than in the control group (P < .05), while hemoglobin (Hgb) and hematocrit (Hct) were higher (P < .05).

CONCLUSIONS

HDP endangers the health of mother and infant; Age, body mass index (BMI) (>24 kg/m2), parity, history of hypertension, family history of hypertension and other factors may be involved in the occurrence and development of HDP.
