Objectives: This study aims to investigate the effects of blood pressure control level on maternal and perinatal outcomes
in pregnant women with mild to moderate gestational hypertension (GHp).
Material and methods: A total of 344 pregnant women who initially diagnosed as mild to moderate gestational hypertension
were recruited in this study. They were divided into 4 groups according to the stabilized blood pressure level (BPL)
during pregnancy. The clinical parameters and the incidence of adverse pregnancy outcomes were compared among the
four groups. The association between blood pressure levels and relative factors were analyzed using the χ2 test. Multivariate
logistic regression analysis was adopted for risk factors associated with adverse pregnancy outcomes.
Results: The results showed the prevalence of obesity was significantly associated with blood pressure levels of mild-moderate
GHp pregnant women (p = 0.029). The incidence of severe GHp, SPE in group A, group B, and group C were statistically
significant (p < 0.001, p = 0.041, respectively). In the patients who used drugs to control BPL, the incidence of severe GHp
has a significant association with the initial blood pressure levels (p = 0.004). However, no significant difference was found
in the incidence of sPE, PE + Upro, and SGA (all p > 0.05). Multivariate logistic regression analyses results showed that the
gestational factor BPL was an independent risk factor for the incidence of sGHp. The AMA, primigravida, gestational BPL, and
edema were risk factors for the incidence of preeclampsia with proteinuria. To the incidence of sPE, gestational BPL is the
independent risk factor. Finally, preeclampsia anamnesis and FGR trend are the high-risk parameters to the incidence of SGA.
Conclusions: Timely management and control of blood pressure in pregnant women with mild to moderate GHp were
beneficial to reduce the occurrence of severe GHp and sPE, but the incidence of SGA does not affected.
