Hypertensive Disorders: Prevalence, Perinatal Outcomes and Cesarean Section Rates in Pregnant Women Hospitalized for Delivery

Abstract

Objective To evaluate the prevalence of hypertensive disorders, perinatal outcomes (preterm infants, low birthweight infants and Apgar score < 7 at the 5th minute and fetal deaths) and the cesarean rates in pregnant women hospitalized for delivery at the Maternidade Hilda Brandão da Santa Casa de Belo Horizonte, Belo Horizonte, state of Minas Gerais, Brazil, from March 1, 2008 to February 28, 2018. Methods A case-control study was performed, and the groups selected for comparison were those of pregnant women with and without hypertensive disorders. Out of the 36,724 women, 4,464 were diagnosed with hypertensive disorders and 32,260 did not present hypertensive disorders Results The prevalence of hypertensive disorders was 12.16%; the perinatal outcomes and cesarean rates between the 2 groups with and without hypertensive disorders were: preterm infants (21.70% versus 9.66%, odds ratio [OR] 2.59, 95% confidence interval [CI], 2.40–2.80, p < 0.001); low birthweight infants (24.48% versus 10.56%; OR 2.75; 95% CI, 2.55–2.96; p < 0.001); Apgar score < 7 at the 5th minute (1.40% versus 1.10%; OR 1.27; 95% CI, 0.97–1.67; p = 0.84); dead fetuses diagnosed prior to delivery (1.90% versus 0.91%; OR 2.12; 95% CI, 1.67–2.70; p < 0.001); cesarean rates (60.22% versus 31.21%; OR 3.34; 95% CI, 3.14–3.55; p < 0.001). Conclusion Hypertensive disorders are associated with higher rates of cesarean deliveries and higher risk of preterm infants, low birthweight infants and a higher risk of fetal deaths.

Prevalence of Preeclampsia in Brazil: An Integrative Review

“…13 Seven studies 10 13 14 15 16 17 18 did not report the occurrence of eclampsia. In the other 3 studies that reported eclampsia, it ranged from 1.66% 19 to 6.19%. 11 Only one case of HELLP syndrome was reported in one study, 13 which also reported a frequency of 30 cases of preeclampsia.…”

“…Those articles were read in full considering the inclusion and exclusion criteria were considered. Then, ten articles 10 11 12 13 14 15 16 17 18 19 were included in the present review. Figure 1 shows the inclusion flowchart.…”

“…We also estimated the pooled prevalence of eclampsia regarding the three studies 11 12 19 that reported cases of it. Our metanalysis showed a prevalence of 3.3% (CI: 0.3–8.5%; I 2 = 76.3%).…”

Prediction of odds for emergency cesarean section: A secondary analysis of the CHILD term birth cohort study

“…Similar to the findings from the previous studies [ 31 – 34 ], we found that multiparous with a history of previous vaginal delivery and with cephalic presentation had lower risk of CS delivery. Hypertensive disorders of pregnancy increased the risk of CS delivery [ 35 ]. Nulliparous women have significant higher risk of developing hypertensive related disorders than multiparous women [ 36 , 37 ].…”
