RESUMEN
BACKGROUND: Black women with peripartum cardiomyopathy (PPCM) have a higher prevalence of hypertensive disorders of pregnancy (HDP) and worse clinical outcomes compared with non-Black women. We examined the impact of HDP on myocardial recovery in Black women with PPCM. METHODS: A total of 100 women were enrolled into the Investigation in Pregnancy Associated Cardiomyopathy (IPAC) study. Left ventricular ejection fraction (LVEF) was assessed by echocardiography at entry, 6, and 12-months post-partum (PP). Women were followed for 12 months postpartum and outcomes including persistent cardiomyopathy (LVEF ≤35%), left ventricular assist device, (LVAD), cardiac transplantation, or death were examined in subsets based on race and the presence of HDP. RESULTS: Black women with HDP were more likely to present earlier compared to Black women without HDP (days PP HDP: 34 ± 21 vs 54 ± 27 days, P = .03). There was no difference in LVEF at study entry for Black women based on HDP, but better recovery with HDP at 6 (HDP: 52 ± 11% vs no HDP: 40 ± 14%, P = .03) and 12-months (HDP:53 ± 10% vs no HDP:40 ± 16%, P = .02). At 12-months, Black women overall had a lower LVEF than non-Black women (P < .001), driven by less recovery in Black women without HDP compared to non-Black women (P < .001). In contrast, Black women with HDP had a similar LVEF at 12 months compared to non-Black women (P = .56). CONCLUSIONS: In women with PPCM, poorer outcomes evident in Black women were driven by women without a history of HDP. In Black women, a history of HDP was associated with earlier presentation and recovery which was comparable to non-Black women.

OBJECTIVE: Remote self-measured blood pressure (SMBP) programs improve racial health equity among postpartum people with hypertensive disorders of pregnancy (HDP) who receive recommended blood pressure ascertainment after hospital discharge.1-3 However, as prior studies have been conducted within racially diverse but ethnically homogeneous populations,1-3 the effect of SMBP programs on ethnicity-based inequities is less understood.4 We examined whether SMBP rates differed among Hispanic versus non-Hispanic participants in remote SMBP programs. STUDY DESIGN: This is a planned secondary analysis of a RCT conducted among postpartum patients with HDP who were enrolled into our remote SMBP program, in which they obtain SMBP and then manually enter the SMBP value into a patient portal for individual provider response. In the parent trial, consenting patients were randomized to continued manual blood pressure entry of SMBP or use of a Bluetooth-enabled blood pressure cuff synched to a smartphone application utilizing artificial intelligence to respond to each obtained blood pressure or symptom for six weeks and to flag abnormalities for providers. Both SMBP programs were available in Spanish and English. For this study, women who self-reported their ethnicity were stratified into two ethnic groups - Hispanic and non-Hispanic - regardless of randomization group. Those who did not self-report ethnicity but completed all study procedures in Spanish were also categorized as Hispanic. Outcomes were the same in the parent study and this secondary analysis. The primary outcome was ≥1 SMBP assessment within 10 days postpartum. Secondary outcomes included number of blood pressure assessments and healthcare utilization outcomes (remote antihypertensive medication initiation or dose-increase and presentation to the Emergency Department or readmission for hypertension within 30 days of discharge). Participants rated their experience with SMBP via a scale from 0 (worst possible) to 10 (best possible) and the Decision Regret Scale, which assessed their regret in SMBP program participation (0=no regret; 100=high regret)).5 Outcomes were compared between groups. Risk differences (RD) were calculated for categorical and regression coefficients for continuous outcomes. The parent RCT was IRB-approved and published on clinicaltrials.gov (NCT05595629) before enrollment. RESULTS: Among 119 women in the parent study, 83 (70%) self-reported ethnicity and the proportion of Hispanic people was similar in both treatment groups. This study compared 23 Hispanic (19% monolingual in Spanish) to 62 non-Hispanic women. Rates of SMBP assessment within 10 days postpartum was similar (Hispanic 64% vs non-Hispanic 79%; RD -0.1 (95% Confidence Interval (CI) -0.4, 0.1). There were no differences in mean number of remote SMBP assessments or rates of remote antihypertensive medication initiation or dose titration. The rates of hypertension-related presentations to the Emergency Department or hospital readmission were also similar between groups. Lastly, regardless of ethnicity, participants had low scores on the Decision Regret Scale and rated their experience with their remote SMBP program highly favorably. (See Table 1.) Conclusion: Hispanic and non-Hispanic postpartum patients with HDP had similar outcomes and favorable patient perceptions. The small sample size in this study may have produced inadequate power to detect a difference between study groups, thereby leading to Type II error. Thus, more research on Hispanic participants in remote SMBP programs is needed. However, the effect of remote SMBP programs on perinatal equity may not be limited to race-based disparities.

OBJECTIVE: To evaluate whether hypertensive disorders of pregnancy, including gestational hypertension, preeclampsia, and eclampsia, are associated with cognitive decline later in life among U.S. Hispanic/Latina individuals. METHODS: The HCHS/SOL (Hispanic Community Health Study/Study of Latinos) is a prospective population-based study of Hispanic/Latino individuals aged 18-74 years from four U.S. communities. This analysis included parous individuals aged 45 years or older who participated in the HCHS/SOL clinic study visit 1 (2008-2011) neurocognitive assessment and subsequently completed a repeat neurocognitive assessment as part of the Study of Latinos-Investigation of Neurocognitive Aging ancillary study visit 2 (2015-2018). Hypertensive disorders of pregnancy were assessed retrospectively by self-report of any gestational hypertension, preeclampsia, or eclampsia. Cognitive functioning was measured at both study visits with the Brief Spanish-English Verbal Learning Test, Digit Symbol Substitution, and Word Fluency. A regression-based approach was used to define cognitive decline at visit 2 as a function of cognition at visit 1 after adjustment for age, education, and follow-up time. Linear regression models were used to determine whether hypertensive disorders of pregnancy or their component diagnoses were associated with standardized cognitive decline after adjustment for sociodemographic characteristics, clinical and behavioral risk factors, and follow-up time. RESULTS: Among 3,554 individuals included in analysis, the mean age was 56.2 years, and 467 of individuals (13.4%) reported at least one hypertensive disorder of pregnancy. Individuals with hypertensive disorders of pregnancy compared with those without were more likely to have higher mean systolic blood pressure, fasting glucose, and body mass index. After an average of 7 years of follow-up, in fully adjusted models, gestational hypertension was associated with a 0.17-SD relative decline in Digit Symbol Substitution scores (95% CI, -0.31 to -0.04) but not other cognitive domains (Brief Spanish-English Verbal Learning Test or Word Fluency). Neither preeclampsia nor eclampsia was associated with neurocognitive differences. CONCLUSION: The presence of preeclampsia or eclampsia was not associated with interval neurocognitive decline. In this cohort of U.S. Hispanic/Latina individuals, gestational hypertension alone was associated with decreased processing speed and executive functioning later in life.

BACKGROUND: Hypertensive disorders of pregnancy (HDP) are maternity-related increases in blood pressure (eg, gestational hypertension, preeclampsia, and eclampsia). Compared with women of other races in high-income countries, Black women have a comparatively higher risk of an HDP. Intersectionality helps to provide a deeper understanding of the multifactorial identities that affect health outcomes in this high-risk population. OBJECTIVE: In this review, we sought to explore the literature on HDP risk factors in Black women living in high-income countries and to assess the interaction of these risk factors using the conceptual framework of intersectionality. METHODS: We conducted this review using the Arksey and O'Malley methodology with enhancements from Levac and colleagues. Published articles in English on HDP risk factors with a sample of not less than 10% of Black women in high-income countries were included. Six databases, theses, and dissertations were searched from January 2000 to July 2021. A thematic analysis was used to summarize the results. RESULTS: A final total of 36 studies were included from the 15 480 studies retrieved; 4 key themes of HDP risks were identified: (1) biological; (2) individual traditional; (3) race and ethnicity, geographical location, and immigration status; and (4) gender related. These intersectional HDP risk factors intersect to increase the risk of HDP among Black women living in high-income countries. CONCLUSION: Upstream approaches are recommended to lower the risks of HDP in this population.

OBJECTIVE: To compare rates of pregnancy induced hypertensive disorders during the period of the COVID-19 pandemic to prior, baseline years. METHODS: We conducted a retrospective study of 17,742 patients on rates for pregnancy induced hypertensive disorders delivering at 2 local hospitals before (Cohort 1; January 2018 to December 2019; n = 8245) and after (Cohort 2; February 2020 to February 2022; n = 9497) the onset of the COVID-19 pandemic. The primary outcomes were rates of gestational hypertension, pre-eclampsia, and chronic hypertension in patients.Wecompared by year (2018-2022), by patient COVID infection status, and by racial demographics. RESULTS: During the pandemic (Cohort 2), there were lower rates of chronic hypertension (7.4 % vs 6.5 %, p =.02), higher rates of gestational hypertension (26.3 % vs 27.8 %, p =.03), and higher rates of preeclampsia (11.3 % vs 13.1 %, p <.001) compared to years prior to the pandemic (Cohort 1). When evaluating by year, rates of chronic hypertension did not statistically change while rates for preeclampsia increased in the first year of the pandemic and remained high, and rates for gestational hypertension did not increase until the second year of the pandemic. When evaluating by COVID infection status, rates for gestational hypertension were significantly higher for individuals with a positive COVID infection status (COVID negative = 27.4 % vs. COVID positive = 32.8 %; p <.004). Rates of preeclampsia did not differ according to COVID infection status (p = 0.15). CONCLUSION: In this study, rates of pregnancy induced hypertensive disorders increased during the COVID pandemic regardless of COVID infection status.

OBJECTIVES: To evaluate the relationship between hypertensive (HTN) disorders and severe maternal morbidity (SMM). To understand whether there is differential prevalence of HTN disorders by race and whether the relationship between HTN disorders and SMM is modified by race and ethnicity. METHODS: We performed a retrospective cohort study using patient-level rates of SMM for pregnancies at all 61 non-military hospitals in Washington State from 10/2015 to 9/2016. Data were obtained from the Washington State Comprehensive Hospital Abstract Reporting System. Adjusted odds ratios (OR) and 95% confidence intervals (CI) were calculated to evaluate the association of HTN disorders and SMM (with and without transfusion) overall and by race. The population-attributable fraction of HTN disorders on SMM within each racial/ethnic group was calculated. RESULTS: Of 76,965 deliveries, 864 (1.1%) had any SMM diagnosis or procedure. All racial and ethnic minorities, except white and Asian, were disproportionally affected by preeclampsia with severe features (SF) and SMM. Overall, and within each racial/ethnic group, the SMM rate was higher among pregnancies with any HTN disorder compared to no HTN disorder (2.8 vs. 0.9%, OR 3.1, 95% CI 2.7-3.6). Race and ethnicity significantly modified the association. Overall and within each racial/ethnic group, there was a dose-response relationship between the type of HTN disorder and SMM, with more severe HTN disorders leading to a greater risk of SMM. The population-attributable fraction of HTN disorders on SMM was 20.6% for Black individuals versus 17.5% overall. The findings were similar when reclassifying transfusion-only SMM as no SMM. CONCLUSIONS: In Washington, HTN disorders are associated with SMM in a dose-dependent fashion with the greatest impact among Black individuals.

Black women in the United States have the highest incidence of hypertensive disorders of pregnancy (HDP) and are disproportionately burdened by its adverse sequalae, compared with women of all racial and ethnic groups. Segregation, a key driver of structural racism for Black families, can provide information critical to understanding these disparities. We examined the association between racial and economic segregation at 2 points and incident HDP using intergenerationally linked birth records of 45,204 Black California-born primiparous mothers (born 1982-1997) and their infants (born 1997-2011), with HDP ascertained from hospital discharge records. Women's early childhood and adulthood neighborhoods were categorized as deprived, mixed, or privileged based on the Index of Concentration at the Extremes (a measure of concentrated racial and economic segregation), yielding 9 life-course trajectories. Women living in deprived neighborhoods at both time points experienced the highest odds of HDP (from mixed effect logistic regression, unadjusted odds ratio = 1.26, 95% confidence interval: 1.13, 1.40) compared with women living in privileged neighborhoods at both time points. All trajectories involving residence in a deprived neighborhood in early childhood or adulthood were associated with increased odds of HDP, whereas mixed-privileged and privileged-mixed trajectories were not. Future studies should assess the causal nature of these associations.

OBJECTIVE: This study aimed to examine whether there are racial disparities in severe maternal morbidity (SMM) in patients with hypertensive disorders of pregnancy (HDP). STUDY DESIGN: Secondary analysis of an observational study of 115,502 patients who had a live birth at ≥20 weeks in 25 hospitals in the United States from 2008 to 2011. Only patients with HDP were included in this analysis. Race and ethnicity were categorized as non-Hispanic White, non-Hispanic Black (NHB), and Hispanic and were abstracted from the medical charts. Patients of other races and ethnicities were excluded. Associations were estimated between race and ethnicity, and the primary outcome of SMM, defined as any of the following, was estimated by unadjusted logistic and multivariable backward logistic regressions: blood transfusion ≥4 units, unexpected surgical procedure, need for a ventilator ≥12 hours, intensive care unit (ICU) admission, or failure of ≥1 organ system. Multivariable models were run classifying HDP into three levels as follows: (1) gestational hypertension; (2) preeclampsia (mild, severe, or superimposed); and (3) eclampsia or HELLP (hemolysis, elevated liver enzymes, and low platelet count) syndrome. RESULTS: A total of 9,612 individuals with HDP met inclusion criteria. No maternal deaths occurred in this cohort. In univariable analysis, non-Hispanic White patients were more likely to present with gestational hypertension whereas NHB and Hispanic patients were more likely to present with preeclampsia. The frequency of the primary outcome, composite SMM, was higher in NHB patients compared with that in non-Hispanic White or Hispanic patients (11.8 vs. 4.5% in non-Hispanic White and 4.8% in Hispanic, p < 0.001). This difference was driven by a higher frequency of blood transfusions and ICU admissions among NHB individuals. Prior to adjusting the analysis for confounding factors, the odds ratio (OR) of primary composite outcomes in NHB individuals was 2.85 (95% confidence interval [CI]: 2.38, 3.42) compared with non-Hispanic White. After adjusting for sociodemographic and clinical factors, hospital site, and the severity of HDP, the OR of composite SMM did not differ between the groups (adjusted OR [aOR] = 1.26, 95% CI: 0.95, 1.67 for NHB, and aOR = 1.29, 95% CI: 0.94, 1.77 for Hispanic, compared with non-Hispanic White patients). Sensitivity analysis was done to exclude one single site that was an outliner with the highest ICU admissions and demonstrated no difference in ICU admission by maternal race and ethnicity. CONCLUSION: NHB patients with HDP had higher rates of the composite SMM compared with non-Hispanic White patients, driven mainly by a higher frequency of blood transfusions and ICU admissions. However, once severity and other confounding factors were taken into account, the differences did not persist. KEY POINTS: · Black patients with HDP had higher frequency of SMM compared with non-Hispanic White patients.. · The SMM disparities were driven by blood transfusions and ICU admissions.. · After adjustment for confounders, including HDP severity, the significant difference in SMM did not persist..

Importance: Gestational diabetes, which increases the risk of adverse pregnancy outcomes, has been increasing in frequency across all racial and ethnic subgroups in the US. Objective: To assess whether the frequency of adverse pregnancy outcomes among those in the US with gestational diabetes changed over time and whether the risk of these outcomes differed by maternal race and ethnicity. Design, Setting, and Participants: Exploratory serial, cross-sectional, descriptive study using US National Center for Health Statistics natality data for 1â¯560â¯822 individuals with gestational diabetes aged 15 to 44 years with singleton nonanomalous live births from 2014 to 2020 in the US. Exposures: Year of delivery and race and ethnicity, as reported on the birth certificate, stratified as non-Hispanic American Indian, non-Hispanic Asian/Pacific Islander, non-Hispanic Black, Hispanic/Latina, and non-Hispanic White (reference group). Main Outcomes and Measures: Maternal outcomes of interest included cesarean delivery, primary cesarean delivery, preeclampsia or gestational hypertension, intensive care unit (ICU) admission, and transfusion; neonatal outcomes included large for gestational age (LGA), macrosomia (>4000 g at birth), small for gestational age (SGA), preterm birth, and neonatal ICU (NICU) admission, as measured by the frequency (per 1000 live births) with estimation of mean annual percentage change (APC), disparity ratios, and adjusted risk ratios. Results: Of 1â¯560â¯822 included pregnant individuals with gestational diabetes (mean [SD] age, 31 [5.5] years), 1% were American Indian, 13% were Asian/Pacific Islander, 12% were Black, 27% were Hispanic/Latina, and 48% were White. From 2014 to 2020, there was a statistically significant increase in the overall frequency (mean APC per year) of preeclampsia or gestational hypertension (4.2% [95% CI, 3.3% to 5.2%]), transfusion (8.0% [95% CI, 3.8% to 12.4%]), preterm birth at less than 37 weeks (0.9% [95% CI, 0.3% to 1.5%]), and NICU admission (1.0% [95% CI, 0.3% to 1.7%]). There was a significant decrease in cesarean delivery (-1.4% [95% CI, -1.7% to -1.1%]), primary cesarean delivery (-1.2% [95% CI, -1.5% to -0.9%]), LGA (-2.3% [95% CI, -2.8% to -1.8%]), and macrosomia (-4.7% [95% CI, -5.3% to -4.0%]). There was no significant change in maternal ICU admission and SGA. In comparison with White individuals, Black individuals were at significantly increased risk of all assessed outcomes, except LGA and macrosomia; American Indian individuals were at significantly increased risk of all assessed outcomes except cesarean delivery and SGA; and Hispanic/Latina and Asian/Pacific Islander individuals were at significantly increased risk of maternal ICU admission, preterm birth, NICU admission, and SGA. Differences in adverse outcomes by race and ethnicity persisted through these years. Conclusions and Relevance: From 2014 through 2020, the frequency of multiple adverse pregnancy outcomes in the US increased among pregnant individuals with gestational diabetes. Differences in adverse outcomes by race and ethnicity persisted.

INTRODUCTION: Hypertensive disorders of pregnancy are a leading cause of maternal and perinatal mortality and morbidity worldwide. We studied the prevalence of hypertensive disorders of pregnancy among women of migrant origin in Finland. MATERIAL AND METHODS: This study used data from the nationwide Medical Birth Register. Information on the most recent singleton birth of women who delivered between 2004 and 2014 (n = 382 233) was included. Women were classified into nine regional categories based on the country of origin. Women of Finnish origin were the reference group. Generalized linear models adjusted for maternal age, socioeconomic position, smoking in pregnancy, parity, pre-pregnancy body mass index, preexisting diabetes and delivery year were used to study the association between region/country of origin and hypertensive disorders of pregnancy. RESULTS: Among the study population, almost 8% were of migrant origin. The prevalence of hypertensive disorders of pregnancy varied from 1.3% (women of East Asian origin) to 4.2% (women of Sub-Saharan African origin), compared with 4.6% in the Finnish origin reference group. Compared with women of Finnish origin, the risk for any hypertensive disorders of pregnancy after adjustment for confounders was lower for women of migrant origin, with an exception for women of Sub-Saharan African origin. When analyzing gestational hypertension and preeclampsia outcomes separately, Sub-Saharan African origin women had a lower risk for gestational hypertension (risk ratio [RR] 0.41, 95% confidence interval [CI] 0.30-0.56) but a higher risk for preeclampsia (RR 1.77, 95% CI 1.44-2.17) than women of Finnish origin. CONCLUSIONS: In general, women of migrant origin in Finland had a lower risk for any hypertensive disorders of pregnancy and gestational hypertension. The risk for preeclampsia was higher among women of Sub-Saharan African origin and may warrant special attention.

OBJECTIVE: To evaluate whether pregnancy outcomes associated with hypertensive disorders of pregnancy in twin pregnancies differ relatively from those in singleton pregnancy. METHODS: We conducted a retrospective, population-based cohort study of all women with a liveborn singleton or twin hospital birth in Ontario, Canada, between 2012 and 2019. Data were obtained from the Better Outcomes Registry & Network Ontario. Pregnancy outcomes were compared between women with and without hypertensive disorders of pregnancy in twin gestations, and separately in singleton gestations. Adjusted relative risks (aRRs) and 95% CIs were generated using modified Poisson regression and were compared between twins and singletons using relative risk ratios. RESULTS: Overall, 932,218 women met the study criteria, of whom 917,542 (98.4%) and 14,676 (1.6%) had singleton and twin gestations, respectively. The incidence of hypertensive disorders of pregnancy was higher in women with twin compared with singleton gestations (14.4% vs 6.4%, aRR 1.85 [1.76-1.94]). Hypertensive disorders of pregnancy were associated with certain adverse outcomes in singleton gestations only and with other adverse outcomes in both the singleton and twin gestations, but the aRR was lower in twins. For example, preterm birth before 37 weeks of gestation (singletons: 15.2% [hypertensive disorders of pregnancy] vs 5.4% [no hypertensive disorders of pregnancy], aRR 2.42; twins: 67.5% [hypertensive disorders of pregnancy] vs 50.4% [no hypertensive disorders of pregnancy], aRR 1.30) and neonatal respiratory morbidity (singletons: 16.3% [hypertensive disorders of pregnancy] vs 8.7% [no hypertensive disorders of pregnancy], aRR 1.50; twins: 39.8% [hypertensive disorders of pregnancy] vs 32.7% [no hypertensive disorders of pregnancy], aRR 1.13). These findings persisted in the subgroups of women with preeclampsia and early-onset preeclampsia. CONCLUSIONS: Although the absolute risk of adverse maternal and neonatal outcomes is higher in twin compared with singleton pregnancies, the incremental risk of adverse outcomes associated with hypertensive disorders in twin pregnancies is lower than the incremental risk in singleton pregnancies. These findings may be attributed in part to the higher baseline risk of preterm birth and adverse maternal and perinatal outcomes in twin compared with singleton pregnancies.

Patients with a history of hypertensive disorders of pregnancy (HDP) suffer higher rates of long-term cardiovascular events including heart failure, coronary artery disease, and stroke. Cardiovascular changes during pregnancy can act as a natural stress test, subsequently unmasking latent cardiovascular disease in the form of HDP. Because HDP now affect 10% of pregnancies in the United States, the American Heart Association has called for physicians who provide peripartum care to promote early identification and cardiovascular risk reduction. In this review, we discuss the epidemiology, pathophysiology, and outcomes of HDP-associated cardiovascular disease. In addition, we propose a multi-pronged approach to support cardiovascular risk reduction for women with a history of HDP. Additional research is warranted to define appropriate blood pressure targets in the postpartum period, optimize the use of pregnancy history in risk stratification tools, and clarify the effectiveness of preventive interventions. The highest rates of HDP are in populations with poor access to resources and quality health care, making it a major risk for inequity of care. Interventions to decrease long-term cardiovascular disease risk in women following HDP must also target disparity reduction.

OBJECTIVE: Postpartum hypertension is a leading cause of readmission in the postpartum period. We aimed to examine the prevalence of racial/ethnic differences in postpartum readmission due to hypertension in women with antepartum pregnancy-associated hypertension. STUDY DESIGN: This was a multi-institutional retrospective cohort study of all women with antepartum pregnancy-associated hypertension diagnosed prior to initial discharge from January 2009 to December 2016. Antepartum pregnancy-associated hypertension, such as gestational hypertension, preeclampsia (with or without severe features), hemolysis, elevated liver enzyme, low platelet (HELLP) syndrome, and eclampsia was diagnosed based on American College of Obstetricians and Gynecologists Task Force definitions. Women with chronic hypertension and superimposed preeclampsia were excluded. Our primary outcome was postpartum readmission defined as a readmission due to severe hypertension within 6 weeks of postpartum. Risk factors including maternal age, gestational age at admission, insurance, race/ethnicity (self-reported), type of antepartum pregnancy-associated hypertension, marital status, body mass index (kg/m2), diabetes (gestational or pregestational), use of antihypertensive medications, mode of delivery, and postpartum day 1 systolic blood pressure levels were examined. Multivariable logistic regression models were performed to calculate adjusted odds ratios (aORs) and 95% confidence intervals (95% CIs). RESULTS: Of 4,317 women with pregnancy-associated hypertension before initial discharge, 66 (1.5%) had postpartum readmission due to hypertension. Risk factors associated with postpartum readmission due to hypertension included older maternal age (aOR = 1.44; 95% CI: 1.20-1.73 for every 5 year increase) and non-Hispanic black race (aOR = 2.12; 95% CI: 1.16-3.87). CONCLUSION: In women with pregnancy-associated hypertension before initial discharge, non-Hispanic black women were at increased odds of postpartum readmission due to hypertension compared with non-Hispanic white women.

Importance: Maternal morbidity and mortality are increasing in the United States, most of which occur post partum, with significant racial disparities, particularly associated with hypertensive disorders of pregnancy. Blood pressure trajectory after a hypertensive disorder of pregnancy has not been previously described. Objectives: To describe the blood pressure trajectory in the first 6 weeks post partum after a hypertensive disorder of pregnancy and to evaluate whether blood pressure trajectories differ by self-reported race. Design, Setting, and Participants: This prospective cohort study included deliveries between January 1, 2018, and December 31, 2019. Women with a clinical diagnosis of a hypertensive disorder of pregnancy were enrolled in a postpartum remote blood pressure monitoring program at the time of delivery and were followed up for 6 weeks. Statistical analysis was performed from April 6 to 17, 2020. Main Outcomes and Measures: Mixed-effects regression models were used to display blood pressure trajectories in the first 6 weeks post partum. Results: A total of 1077 women were included (mean [SD] age, 30.2 [5.6] years; 804 of 1017 White [79.1%] and 213 of 1017 Black [20.9%]). Systolic and diastolic blood pressures were found to decrease rapidly in the first 3 weeks post partum, with subsequent stabilization (at 6 days post partum: mean [SD] peak systolic blood pressure, 146 [13] mm Hg; mean [SD] peak diastolic blood pressure, 95 [10] mm Hg; and at 3 weeks post partum: mean [SD] peak systolic blood pressure, 130 [12] mm Hg; mean [SD] peak diastolic blood pressure, 85 [9] mm Hg). A significant difference was seen in blood pressure trajectory by race, with both systolic and diastolic blood pressure decreasing more slowly among Black women compared with White women (mean [SD] peak systolic blood pressure at 1 week post partum: White women, 143 [14] mm Hg vs Black women, 146 [13] mm Hg; P = .01; mean [SD] peak diastolic blood pressure at 1 week post partum: White women, 92 [9] mm Hg vs Black women, 94 [9] mm Hg; P = .02; and mean [SD] peak systolic blood pressure at 3 weeks post partum: White women, 129 [11] mm Hg vs Black women, 136 [15] mm Hg; P < .001; mean [SD] peak diastolic blood pressure at 3 weeks post partum: White women, 84 [8] mm Hg vs Black women, 91 [13] mm Hg; P < .001). At the conclusion of the program, 126 of 185 Black women (68.1%) compared with 393 of 764 White women (51.4%) met the criteria for stage 1 or stage 2 hypertension (P < .001). Conclusions and Relevance: This study found that, in the postpartum period, blood pressure decreased rapidly in the first 3 weeks and subsequently stabilized. The study also found that, compared with White women, Black women had a less rapid decrease in blood pressure, resulting in higher blood pressure by the end of a 6-week program. Given the number of women with persistent hypertension at the conclusion of the program, these findings also appear to support the importance of ongoing postpartum care beyond the first 6 weeks after delivery.

OBJECTIVE: To characterize stillbirths associated with pregestational diabetes and gestational diabetes mellitus (GDM) in a large, prospective, U.S. case-control study. METHODS: A secondary analysis of stillbirths among patients enrolled in a prospective; multisite; geographically, racially, and ethnically diverse case-control study in the United States was performed. Singleton gestations with complete information regarding diabetes status and with a complete postmortem evaluation were included. A standard evaluation protocol for stillbirth cases included postmortem evaluation, placental pathology, clinical testing as performed at the discretion of the health care professional, and a recommended panel of tests. A potential cause of death was assigned to stillbirth cases using a standardized classification tool. Demographic and delivery characteristics among women with pregestational diabetes and GDM were compared with characteristics of women with no diabetes in pairwise comparisons using χ or two-sample t tests as appropriate. Sensitivity analysis was performed excluding pregnancies with genetic conditions or major fetal malformations. RESULTS: Of 455 stillbirth cases included in the primary analysis, women with stillbirth and diabetes were more likely to be older than 35 years and have a higher body mass index. They were also more likely to have a gestational hypertensive disorder than women without diabetes (28% vs 9.1%; P<.001). Women with pregestational diabetes had more large-for-gestational-age (LGA) neonates (26% vs 3.4%; P<.001). Stillbirths occurred more often at term in women with pregestational diabetes (36%) and those with GDM (52%). Maternal medical complications, including pregestational diabetes and others, were more often identified as a probable or possible cause of death among stillbirths with maternal diabetes (43% vs 4%, P<.001) as compared with stillbirths without diabetes. CONCLUSION: Compared with stillbirths in women with no diabetes, stillbirths among women with pregestational diabetes and GDM occur later in pregnancy and are associated with hypertensive disorders of pregnancy, maternal medical complications, and LGA.

Background: Hypertensive disorders of pregnancy are a recognized risk factor of a woman's future cardiovascular risk. The potential role of micronutrients in mitigating hypertensive disorders is not fully understood. This study examined maternal postpartum plasma B vitamin profiles by hypertensive disorders of pregnancy in a high-risk multiethnic U.S. population. Materials and Methods: The analyses included 2584 mothers enrolled within 3 days postpartum at the Boston Medical Center. Hypertensive disorders of pregnancy included gestational hypertension and pre-eclampsia disorders (pre-eclampsia, eclampsia, hemolysis, elevated liver enzymes, and/or low platelets syndrome) as documented in the medical records. Plasma folate, vitamin B12, and homocysteine levels were measured in blood samples collected at enrollment. Kernel density plots and multivariable regressions were used to examine the relationship between hypertensive disorders and postpartum B vitamin profiles. Results: Of the 2584 mothers, 10% had pre-eclampsia disorders that were associated with significantly lower plasma folate (adjusted beta coefficient (aß): -0.10; 95% CI: -0.22 to -0.06) and increased homocysteine (aß: 0.08; 95% CI: 0.04-0.13), but not with vitamin B12 concentrations. These associations remained robust after adjusting for a range of pertinent covariables and were more pronounced in non-Hispanic Black women compared with other groups. However, gestational hypertension was not significantly associated with any postpartum biomarker. Conclusions: We found that pre-eclampsia disorders, but not gestational hypertension, was associated with lower folate and higher homocysteine levels postpartum, especially among Black mothers. This finding, if further confirmed, may have implications for postpartum care, including attention to maternal micronutrient status to reduce and prevent hypertensive disorders in pregnancy-associated consequences in subsequent pregnancies and lifespan.

Background Preeclampsia and gestational hypertension are hypertensive disorders of pregnancy (HDP) that identify an increased risk of developing chronic hypertension and cardiovascular disease later in life. Postpartum follow-up may facilitate early screening and treatment of cardiovascular risk factors. Our objective is to describe patterns of postpartum visits with primary care and women's health providers (eg, family medicine and obstetrics) among women with and without HDP in a nationally representative sample of commercially insured women. Methods and Results We conducted a retrospective cohort study using insurance claims from a US health insurance database to describe patterns in office visits in the 6 months after delivery. We identified 566 059 women with completed pregnancies between 2005 and 2014. At 6 months, 13% of women with normotensive pregnancies, 18% with HDP, and 23% with chronic hypertension had primary care visits (P<0.0001 for comparing HDP and chronic hypertension groups with control participants). Only 58% of women with HDP had 6-month follow-up with any continuity provider compared with 47% of women without hypertension (P<0.0001). In multivariable analysis, women with severe preeclampsia were 16% more likely to have postpartum continuity follow-up (adjusted odds ratio, 1.16; 95% CI, 1.2-1.21). Factors associated with a lower likelihood of any follow-up included age ≥30 years, Black race, Hispanic ethnicity, and having multiple gestations. Conclusions Rates of continuity care follow-up after a pregnancy complicated by hypertension were low. This represents a substantial missed opportunity to provide cardiovascular risk screening and management to women at increased risk of future cardiovascular disease.

PURPOSE: Childhood adversity is associated with increased risk of adult disease, including type II diabetes and hypertension. However, little is known about potential associations between childhood adversity and adverse pregnancy outcomes. The goal of this study was to examine the relationship between adverse childhood experiences (ACEs) and ever experiencing gestational diabetes mellitus (GDM) or a hypertensive disorder of pregnancy (HDP) in a cohort of Hispanic or Latina women. METHODS: We analyzed data from 2319 women from the Hispanic Community Health Study/Study of Latinos who had ever given birth to a liveborn infant. We fit separate logistic regression models accounting for sample weights to examine the association between ACEs and risk of GDM and HDP adjusting for Hispanic/Latino background, age at immigration to the United States, and education. RESULTS: Women who reported four or more ACEs did not show increased odds of GDM or HDP compared with those who reported three or fewer (GDM adjusted odds ratio: 0.8 [0.5, 1.3]; HDP adjusted OR: 1.0 [0.7, 1.5]). CONCLUSIONS: Unlike previous research with majority non-Hispanic White cohorts, there was no association between ACEs and GDM or HDP. Future research should explore if this relationship varies by race/ethnicity in multiethnic cohorts.

OBJECTIVE: To compare characteristics and outcomes of women with chronic hypertension (cHTN) between those with normal and abnormal plasma angiogenic profiles. STUDY DESIGN: This secondary analysis explored associations between angiogenic markers soluble fms-like tyrosine kinase-1 (sFlt1) and placental growth factor (PlGF) drawn prior to delivery among women with history of cHTN who were enrolled between 22 and 41â¯weeks. Patients were divided into two groups based on sFlt1/PlGF ratio, namely low sFlt1/PlGF (<85) and high sFlt1/PlGF (≥85) ratio. RESULTS: Of the 115 patients, 76% were African American. Compared to women with low sFlt1/PlGF (nâ¯=â¯78), patients with high sFlt1/PlGF (nâ¯=â¯37) had higher median antenatal blood pressures (systolic mmHg 179 vs 155; diastolic 106 vs 91), lower gestational age at delivery (34.7 vs 38.2â¯weeks), lower birthweight (1940 vs 3103â¯g), and a higher prevalence of preterm deliveryâ¯<34 (40.5% vs 7.7%) andâ¯<37â¯weeks (64.9% vs 20.5%), all pâ¯<â¯0.001. Importantly, more women with high sFlt1/PlGF had a diagnosis of superimposed preeclampsia (62.2% vs 26.9%, pâ¯=â¯0.003), preeclampsia with severe features (59.5% vs 20.5%, pâ¯<â¯0.0001), maternal adverse outcomes (24.3% vs 3.9%, pâ¯=â¯0.002), neonatal intensive care unit admissions (71.9% vs 40.8%; pâ¯=â¯0.003), severe postpartum hypertension (67.6% vs 38.5%, pâ¯=â¯0.01) and longer hospital stays (median 6.0 vs 4.5â¯days, pâ¯=â¯0.003). DISCUSSION: In contrast to patients with a low ratio, high sFlt1/PlGF is characterized by an increased risk of maternal adverse outcomes and prematurity. Incorporation of angiogenic biomarkers while managing cHTN may improve accuracy of early identification of adverse outcomes to improve outcomes.

OBJECTIVE: We compared the prevalence of gestational diabetes and hypertensive disorders in the most recent pregnancy among women of Russian, Somali, and Kurdish origin and women in the general population in Finland. METHODS: The study groups were selected from population-based samples of 18- to 64-year-old women. The women were of Russian (n = 318), Somali (n = 583), and Kurdish (n = 373) origin or from the general population (n = 243), and had given birth in Finland between 2004 and 2014. The data were obtained from the National Medical Birth Register and the Hospital Discharge Register. Data on gestational diabetes and hypertensive disorders were extracted based on relevant International Classification of Diseases, Tenth Revision codes. The main statistical methods were logistic regression analyses adjusted for age, parity, body mass index, socioeconomic status, and smoking. RESULTS: The prevalence of gestational diabetes was 19.1% in Kurdish, 14.4% in Somali, 9.3% in Russian, and 11.8% in the general population. The prevalence of hypertensive disorders was 5.4% in the general population, 3.8% in Somali, 3.1% in Kurdish, and 1.7% in Russian. When adjusted for confounders, Kurdish women had two-fold odds for gestational diabetes (odds ratio = 1.98; 95% confidence interval = 1.20-3.32) compared with the general population, but the odds for hypertensive disorders did not differ between groups. CONCLUSION: Women of Kurdish origin were more likely to develop gestational diabetes. Studies with larger samples are required to confirm these findings to develop prevention strategies for later development of type 2 diabetes. Future research including other migrant groups is recommended to identify differences in pregnancy complications among the women in migrant and general population.
