Abstract Background Racial disparities in adverse perinatal outcomes have been studied in other countries, but little has been done for the Canadian population. In this study, we sought to examine the disparities in adverse perinatal outcomes between Asians and Caucasians in Ontario, Canada. Methods We conducted a population-based retrospective cohort study that included all Asian and Caucasian women who attended a prenatal screening and resulted in a singleton birth in an Ontario hospital (April 1st, 2015-March 31st, 2017). Generalized estimating equation models were used to estimate the independent adjusted relative risks and adjusted risk difference of adverse perinatal outcomes for Asians compared with Caucasians. Results Among 237,293 eligible women, 31% were Asian and 69% were Caucasian. Asians were at an increased risk of gestational diabetes mellitus, placental previa, early preterm birth (< 32 weeks), preterm birth, emergency cesarean section, 3rd and 4th degree perineal tears, low birth weight (< 2500 g, < 1500 g), small-for-gestational-age (<10th percentile, <3rd percentile), neonatal intensive care unit admission, and hyperbilirubinemia requiring treatment, but had lower risks of preeclampsia, macrosomia (birth weight > 4000 g), large-for-gestational-age neonates, 5-min Apgar score < 7, and arterial cord pH ≤7.1, as compared with Caucasians. No difference in risk of elective cesarean section was observed between Asians and Caucasians. Conclusion There are significant differences in several adverse perinatal outcomes between Asians and Caucasians. These differences should be taken into consideration for clinical practices due to the large Asian population in Canada.

Adverse Perinatal Outcomes

Background Hypertensive disorders of pregnancy (HDP) increases adverse perinatal outcomes in women with the disorder. About 16% of all still births and 10% of early neonatal deaths are accounted by HDP. In Ethiopia, HDP complicates about 6% of all pregnancies. Hence, the objective of this study was to determine the risk of adverse perinatal outcomes among women with HDP in Jimma Medical Center, southwest Ethiopia. Methods A retrospective cohort study was conducted on a total of 777 women who gave birth from June 2017 to March 2020 at Jimma Medical Center, southwest Ethiopia. Women with HDP and normotensive women who gave birth at or after 28 weeks of gestation were enrolled as exposed and unexposed respectively. Simple random sampling technique was used to select study participants. Data were reviewed using structured data collection performa that was prepared after reviewing relevant literatures. Data were entered to Epi-Data then exported to STATA version 13 for analysis. The adverse perinatal outcomes risk were examined using log binomial and modified Poisson regression model with robust standard errors. Results In this study, the overall incidence of adverse perinatal outcome was higher among women with hypertensive disorders of pregnancy (HDP) than normotensive women (64.1% versus 32.8%). After adjusting for confounders, women with HDP were at higher risk of babies with low birth weight (adjusted RR = 2.88 (2.2, 3.75)), preterm birth(aRR = 2.31(1.7, 3.14)), fifth minute low Apgar score (aRR = 2.6(1.53, 4.42)), admission to neonatal intensive care unit (aRR = 1.77(1.32, 2.37), stillbirth (aRR = 2.02(1.11, 3.01)), and perinatal mortality (aRR = 3.88(1.97, 7.66)) than normotensive women. Conclusion Women with hypertensive disorder of pregnancy were at higher risk of adverse perinatal outcomes than normotensive women who gave birth at Jimma Medical Center, southwest Ethiopia. Therefore, health care providers should strengthen prevention, early diagnosis and prompt management of HDP in order to reduce adverse perinatal outcomes.

Adverse Perinatal Outcomes

AbstractMaternal supraphysiological estradiol (E2) environment during pregnancy leads to adverse perinatal outcomes. However, the influence of oocyte exposure to high E2 levels on perinatal outcomes remains unknown. Thus, a retrospective cohort study was conducted to explore the effect of high E2 level induced by controlled ovarian stimulation (COH) on further outcomes after frozen embryo transfer (FET). The study included all FET cycles (n = 10,581) between 2014 and 2017. All cycles were categorized into three groups according to the E2 level on the day of the human Chorionic Gonadotropin trigger. Odds ratios (ORs) and their confidence intervals (CIs) were calculated to evaluate the association between E2 level during COH and pregnancy outcomes and subsequent neonatal outcomes. From our findings, higher E2 level was associated with lower percentage of chemical pregnancy, clinical pregnancy, ongoing pregnancy, and live birth as well as increased frequency of early miscarriage. Preterm births were more common among singletons in women with higher E2 level during COH (aOR1 = 1.93, 95% CI: 1.22–3.06; aOR2 = 2.05, 95% CI: 1.33–3.06). Incidence of small for gestational age (SGA) was more common in both singletons (aOR1 = 2.01, 95% CI: 1.30–3.11; aOR2 = 2.51, 95% CI: 1.69–3.74) and multiples (aOR1 = 1.58, 95% CI: 1.03–2.45; aOR2 = 1.99, 95% CI: 1.05–3.84) among women with relatively higher E2 level. No association was found between high E2 level during COH and the percentage of macrosomia or large for gestational age. In summary, oocyte exposure to high E2 level during COH should be brought to our attention, since the pregnancy rate decreasing and the risk of preterm birth and SGA increasing following FET.

Objective To determine if women who newly met criteria for stage 1 hypertension in early pregnancy were at increased risk for adverse perinatal outcomes compared with normotensive women. Study Design We conducted a retrospective cohort study of women who had prenatal care at a single institution and subsequently delivered a live infant between December 2017 and August 2019. Women with a singleton gestation who had at least two prenatal visits prior to 20 weeks of gestation were included. We excluded women with known chronic hypertension or other major maternal illness. Two groups were identified: (1) women newly diagnosed with stage 1 hypertension before 20 weeks of gestation (blood pressure [BP] 130–139/80–89 on at least two occasions) and (2) women with no known history of hypertension and normal BP (<130/80 mm Hg) before 20 weeks of gestation. The primary outcome was any hypertensive disorder of pregnancy; secondary outcomes were indicated preterm birth and small for gestational age. Generalized linear models were used to compare risk of adverse outcomes between the groups. Results Of the 1,630 women included in the analysis, 1,443 women were normotensive prior to 20 weeks of gestation and 187 women (11.5%) identified with stage 1 hypertension. Women with stage 1 hypertension were at significantly increased risk for any hypertensive disorder of pregnancy (adjusted risk ratio [aRR]: 1.86, 95% confidence interval [CI]: 1.12–3.04) and indicated preterm birth (aRR: 1.83, 95% CI: 1.12–3.02). Black women and obese women with stage 1 hypertension were at increased for hypertensive disorder of pregnancy compared with white women and nonobese women, respectively (aRR: 1.32, 95% CI: 1.11–1.57; aRR: 1.69, 95% CI: 1.39–2.06). Conclusion These results provide insight about the prevalence of stage 1 hypertension and inform future guidelines for diagnosis and management of hypertension in pregnancy. Future research is needed to assess potential interventions to mitigate risk. Key Points
