Item Association of Adverse Pregnancy Outcomes With Hypertension 2 to 7 Years Postpartum(Wiley Open Access, 2019-10-01) Haas, David M.; Parker, Corette B.; Marsh, Derek J.; Grobman, William A.; Ehrenthal, Deborah B.; Greenland, Philip; Merz, C. Noel Bairey; Pemberton, Victoria L.; Silver, Robert M.; Barnes, Shannon; McNeil, Rebecca B.; Cleary, Kirsten; Reddy, Uma M.; Chung, Judith H.; Parry, Samuel; Theilen, Lauren H.; Blumenthal, Elizabeth A.; Levine, Lisa D.; Mercer, Brian M.; Simhan, Hyagriv; Polito, LuAnn; Wapner, Ronald J.; Catov, Janet; Chen, Ida; Saade, George R. Saade; NHLBI nuMoM2b Heart Health Study; Medicine, School of MedicineBackground Identifying pregnancy-associated risk factors before the development of major cardiovascular disease events could provide opportunities for prevention. The objective of this study was to determine the association between outcomes in first pregnancies and subsequent cardiovascular health. Methods and Results The Nulliparous Pregnancy Outcomes Study Monitoring Mothers-to-be Heart Health Study is a prospective observational cohort that followed 4484 women 2 to 7 years (mean 3.2 years) after their first pregnancy. Adverse pregnancy outcomes (defined as hypertensive disorders of pregnancy, small-for-gestational-age birth, preterm birth, and stillbirth) were identified prospectively in 1017 of the women (22.7%) during this pregnancy. The primary outcome was incident hypertension (HTN). Women without adverse pregnancy outcomes served as controls. Risk ratios (RR) and 95% CIs were adjusted for age, smoking, body mass index, insurance type, and race/ethnicity at enrollment during pregnancy. The overall incidence of HTN was 5.4% (95% CI 4.7% to 6.1%). Women with adverse pregnancy outcomes had higher adjusted risk of HTN at follow-up compared with controls (RR 2.4, 95% CI 1.8-3.1). The association held for individual adverse pregnancy outcomes: any hypertensive disorders of pregnancy (RR 2.7, 95% CI 2.0-3.6), preeclampsia (RR 2.8, 95% CI 2.0-4.0), and preterm birth (RR 2.7, 95% CI 1.9-3.8). Women who had an indicated preterm birth and hypertensive disorders of pregnancy had the highest risk of HTN (RR 4.3, 95% CI 2.7-6.7). Conclusions Several pregnancy complications in the first pregnancy are associated with development of HTN 2 to 7 years later. Preventive care for women should include a detailed pregnancy history to aid in counseling about HTN risk.Item Association of Health Literacy Among Nulliparous Individuals and Maternal and Neonatal Outcomes(American Medical Association, 2021-09-01) Yee, Lynn M.; Silver, Robert; Haas, David M.; Parry, Samuel; Mercer, Brian M.; Wing, Deborah A.; Reddy, Uma; Saade, George R.; Simhan, Hyagriv; Grobman, William A.; Obstetrics and Gynecology, School of MedicineImportance: Health literacy is considered an important social determinant of health that may underlie many health disparities, but it is unclear whether inadequate health literacy among pregnant individuals is associated with adverse maternal and neonatal outcomes. Objective: To assess the association between maternal health literacy and maternal and neonatal outcomes among nulliparous individuals. Design, setting, and participants: This was a secondary analysis of a large, multicenter cohort study of 10 038 nulliparous individuals in the US (2010-2013). Participants underwent 3 antenatal study visits and had detailed maternal and neonatal data abstracted. Data analysis was performed from July to December 2019. Exposures: Between 16 and 21 weeks of gestation, health literacy was assessed using the Rapid Estimate of Adult Literacy in Medicine-Short Form, a validated 7-item word recognition test. In accordance with standard scoring, results were dichotomized as inadequate vs adequate health literacy. Main outcomes and measures: On the basis of theoretical causal pathways between health literacy and health outcomes, a priori maternal and neonatal outcomes (determined via medical records) were selected for this analysis. Multivariable Poisson regression models were constructed to estimate the associations between health literacy and outcomes. Sensitivity analyses in which education was removed from models and that excluded individuals who spoke English as a second language were performed. Results: Of 9341 participants who completed the Rapid Estimate of Adult Literacy in Medicine-Short Form, the mean (SD) age was 27.0 (5.6) years, and 2540 (27.4%) had publicly funded prenatal care. Overall, 1638 participants (17.5%) had scores indicative of inadequate health literacy. Participants with inadequate health literacy were more likely to be younger (mean [SD] age, 22.9 [5.0] vs 27.9 [5.3] years), have less educational attainment (some college education or greater, 1149 participants [73.9%] vs 5279 participants [94.5%]), have publicly funded insurance (1008 participants [62.2%] vs 1532 participants [20.0%]), and report they were a member of an underrepresented racial or ethnic group (non-Hispanic Black, 506 participants [30.9%] vs 780 participants [10.1%]; Hispanic, 516 participants [31.5%] vs 948 participants [12.3%]) compared with those with adequate health literacy. Participants who had inadequate health literacy had greater risk of cesarean delivery (adjusted risk ratio [aRR], 1.11; 95% CI, 1.01-1.23) and major perineal laceration (aRR, 1.44; 95% CI, 1.03-2.01). The adjusted risks of small-for-gestational-age status (aRR, 1.34; 95% CI, 1.14-1.58), low birth weight (aRR, 1.33; 95% CI, 1.07-1.65), and 5-minute Apgar score less than 4 (aRR, 2.78; 95% CI, 1.16-6.65) were greater for neonates born to participants with inadequate health literacy. Sensitivity analyses confirmed these findings. Conclusions and relevance: These findings suggest that inadequate maternal health literacy is associated with a variety of adverse maternal and neonatal outcomes.Item Association of N-Terminal Pro-Brain Natriuretic Peptide Concentration in Early Pregnancy With Development of Hypertensive Disorders of Pregnancy and Future Hypertension(American Medical Association, 2022) Hauspurg, Alisse; Marsh, Derek J.; McNeil, Rebecca B.; Bairey Merz, C. Noel; Greenland, Philip; Straub, Adam C.; Rouse, Caroline E.; Grobman, William A.; Pemberton, Victoria L.; Silver, Robert M.; Chen, Yii-Der Ida; Mercer, Brian M.; Levine, Lisa D.; Hameed, Afshan; Hoffman, Matthew K.; Simhan, Hyagriv N.; Catov, Janet M.; NICHD nuMoM2b and NHLBI nuMoM2b Heart Health Study Networks; Obstetrics and Gynecology, School of MedicineImportance: Hypertensive disorders of pregnancy are associated with future cardiovascular disease, perhaps because of subclinical cardiac dysfunction before pregnancy leading to impaired adaptation to pregnancy. Natriuretic peptides are promising biomarkers for detecting subclinical cardiac dysfunction outside of pregnancy. Objective: To investigate whether higher concentrations of N-terminal pro-brain natriuretic peptide (NT-proBNP) in early pregnancy would be associated with hypertensive disorders of pregnancy and hypertension 2 to 7 years post partum. Design, setting, and participants: This cohort study used data from the The Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-Be Heart Health Study, a prospective multicenter observational study. A total of 4103 nulliparous women with complete data and no prepregnancy hypertension or diabetes who were treated at 8 clinical sites were included. Women were followed up with for 2 to 7 years after pregnancy. Data were collected from October 2010 to October 2017, and data were analyzed from August 2020 to November 2021. Exposures: NT-proBNP concentration, measured using an electrochemiluminescence immunoassay from a first-trimester blood sample. Main outcomes and measures: Hypertensive disorders of pregnancy and incident hypertension (systolic blood pressure of 130 mm Hg or diastolic blood pressure of 80 mm Hg or use of antihypertensive agents) at follow-up visit. Results: A total of 4103 women met inclusion criteria; the mean (SD) age was 27.0 (5.6) years. Among these women, 909 (22.2%) had an adverse pregnancy outcome, and 817 (19.9%) had hypertension at the follow-up visit. Higher NT-proBNP concentrations were associated with a lower risk of hypertensive disorders of pregnancy (adjusted odds ratio per doubling, 0.81; 95% CI, 0.73-0.91), which persisted after adjustment for age, self-reported race and ethnicity, early-pregnancy body mass index, smoking, and aspirin use. Similarly, higher NT-proBNP concentration in early pregnancy was also associated with a lower risk of incident hypertension 2 to 7 years after delivery (adjusted odds ratio per doubling, 0.84; 95% CI, 0.77-0.93), an association that persisted after controlling for confounders, including hypertensive disorders of pregnancy. Conclusions and relevance: In this cohort study, higher NT-proBNP concentrations in early pregnancy were associated with a lower risk of hypertensive disorders of pregnancy and hypertension 2 to 7 years post partum. These findings suggest that normal early-pregnancy cardiovascular physiology, as assessed by NT-proBNP concentration, may provide biologic insights into both pregnancy outcome and cardiovascular disease risk.Item Associations of the Neighborhood Built Environment With Physical Activity Across Pregnancy(Human Kinetics, 2021-04-15) Kershaw, Kiarri N.; Marsh, Derek J.; Crenshaw, Emma G.; McNeil, Rebecca B.; Pemberton, Victoria L.; Cordon, Sabrina A.; Haas, David M.; Debbink, Michelle P.; Mercer, Brian M.; Parry, Samuel; Reddy, Uma; Saade, George; Simhan, Hyagriv; Wapner, Ronald J.; Wing, Deborah A.; Grobman, William A.; NICHD nuMoM2b Heart Health Study Network; NHLBI nuMoM2b Heart Health Study Network; Obstetrics and Gynecology, School of MedicineBackground: Several features of the neighborhood built environment have been shown to promote leisure-time physical activity (PA) in the general population, but few studies have examined its impact on PA during pregnancy. Methods: Data were extracted from 8362 Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-Be cohort participants (2010-2013). Residential address information was linked to 3 built environment characteristics: number of gyms and recreation areas within a 3-km radius of residence and census block level walkability. Self-reported leisure-time PA was measured in each trimester and dichotomized as meeting PA guidelines or not. Relative risks for cross-sectional associations between neighborhood characteristics and meeting PA guidelines were estimated using Poisson regression. Results: More gyms and recreation areas were each associated with a greater chance of meeting PA guidelines in models adjusted for sociodemographic characteristics and preexisting conditions. Associations were strongest in the third trimester where each doubling in counts of gyms and recreation areas was associated with 10% (95% confidence interval, 1.07-1.13) and 8% (95% confidence interval, 1.03-1.12), respectively, greater likelihood of meeting PA guidelines. Associations were similar though weaker for walkability. Conclusions: Results from a large, multisite cohort suggest that these built environment characteristics have similar PA-promoting benefits in pregnant women as seen in more general populations.Item Early Pregnancy Atherogenic Profile in a First Pregnancy and Hypertension Risk 2 to 7 Years After Delivery(American Heart Association, 2021-02) Catov, Janet M.; McNeil, Rebecca B.; Marsh, Derek J.; Mercer, Brian M.; Merz, C. Noel Bairey; Parker, Corette B.; Pemberton, Victoria L.; Saade, George R.; Chen, Yii-Der (Ida); Chung, Judith H.; Ehrenthal, Deborah B.; Grobman, William A.; Haas, David M.; Parry, Samuel; Polito, LuAnn; Reddy, Uma M.; Silver, Robert M.; Simhan, Hyagriv N.; Wapner, Ronald J.; Kominiarek, Michelle; Kreutz, Rolf; Levine, Lisa D.; Greenland, Philip; Obstetrics and Gynecology, School of MedicineBackground: Cardiovascular risk in young adulthood is an important determinant of lifetime cardiovascular disease risk. Women with adverse pregnancy outcomes (APOs) have increased cardiovascular risk, but the relationship of other factors is unknown. Methods and Results: Among 4471 primiparous women, we related first-trimester atherogenic markers to risk of APO (hypertensive disorders of pregnancy, preterm birth, small for gestational age), gestational diabetes mellitus (GDM) and hypertension (130/80 mm Hg or antihypertensive use) 2 to 7 years after delivery. Women with an APO/GDM (n=1102) had more atherogenic characteristics (obesity [34.2 versus 19.5%], higher blood pressure [systolic blood pressure 112.2 versus 108.4, diastolic blood pressure 69.2 versus 66.6 mm Hg], glucose [5.0 versus 4.8 mmol/L], insulin [77.6 versus 60.1 pmol/L], triglycerides [1.4 versus 1.3 mmol/L], and high-sensitivity C-reactive protein [5.6 versus 4.0 nmol/L], and lower high-density lipoprotein cholesterol [1.8 versus 1.9 mmol/L]; P<0.05) than women without an APO/GDM. They were also more likely to develop hypertension after delivery (32.8% versus 18.1%, P<0.05). Accounting for confounders and factors routinely assessed antepartum, higher glucose (relative risk [RR] 1.03 [95% CI, 1.00-1.06] per 0.6 mmol/L), high-sensitivity C-reactive protein (RR, 1.06 [95% CI, 1.02-1.11] per 2-fold higher), and triglycerides (RR, 1.27 [95% CI, 1.14-1.41] per 2-fold higher) were associated with later hypertension. Higher physical activity was protective (RR, 0.93 [95% CI, 0.87-0.99] per 3 h/week). When evaluated as latent profiles, the nonobese group with higher lipids, high-sensitivity C-reactive protein, and insulin values (6.9% of the cohort) had increased risk of an APO/GDM and later hypertension. Among these factors, 7% to 15% of excess RR was related to APO/GDM. Conclusions: Individual and combined first-trimester atherogenic characteristics are associated with APO/GDM occurrence and hypertension 2 to 7 years later.Item Factors associated with duration of breastfeeding in women giving birth for the first time(BMC, 2022-09-22) Haas, David M.; Yang, Ziyi; Parker, Corette B.; Chung, Judith; Parry, Samuel; Grobman, William A.; Mercer, Brian M.; Simhan, Hyagriv N.; Silver, Robert M.; Wapner, Ronald J.; Saade, George R.; Greenland, Philip; Merz, Noel Bairey; Reddy, Uma M.; Pemberton, Victoria L.; nuMoM2b study; nuMoM2b Heart Health Study; Obstetrics and Gynecology, School of MedicineObjective: To examine maternal, psychosocial, and pregnancy factors associated with breastfeeding for at least 6 months in those giving birth for the first time. Methods: We performed a planned secondary analysis of an observational cohort study of 5249 women giving birth for the first time. Women were contacted at least 6 months after delivery and provided information regarding breastfeeding initiation, duration, and exclusivity. Maternal demographics, psychosocial measures, and delivery methods were compared by breastfeeding groups. Results: 4712 (89.8%) of the women breastfed at some point, with 2739 (58.2%) breastfeeding for at least 6 months. Of those who breastfed, 1161 (24.7% of the entire cohort), breastfed exclusively for at least 6 months. In the multivariable model among those who ever breastfed, not smoking in the month prior to delivery (adjusted odds ratio [aOR] 2.04, 95%CI 1.19-3.45), having a Master's degree of higher (aOR 1.89, 95%CI 1.51-2.36), having a planned pregnancy (aOR 1.48, 95%CI 1.27-1.73), older age (aOR 1.02, 95% CI, 1.01-1.04), lower BMI (aOR 0.96 95% CI 0.95-0.97), and having less anxiety measured during pregnancy (aOR 0.990, 95%CI 0.983-0.998) were associated with breastfeeding for at least 6 months. Compared to non-Hispanic White women, Hispanic women, while being more likely to breastfeed initially (aOR 1.40, 95%CI 1.02-1.92), were less likely to breastfeed for 6 months (aOR 0.72, 95%CI 0.59-0.88). While non-Hispanic Black women were less likely than non-Hispanic White women to initiate breastfeeding (aOR 0.68, 95%CI 0.51-0.90), the odds of non-Hispanic Black women of continuing to breastfeed for at least 6 months was similar to non-Hispanic White women (aOR 0.92, 95%CI 0.71-1.19). Conclusions: In this cohort of women giving birth for the first time, duration of breastfeeding was associated with several characteristics which highlight groups at greater risk of not breastfeeding as long as currently recommended.Item Gestational Weight Gain and Pregnancy Outcomes among Nulliparous Women(Thieme, 2021) Dude, Annie M.; Grobman, William; Haas, David; Mercer, Brian M.; Parry, Samuel; Silver, Robert M.; Wapner, Ronald; Wing, Deborah; Saade, George; Reddy, Uma; Iams, Jay; Kominiarek, Michelle A.; Obstetrics and Gynecology, School of MedicineObjective: To determine the association between total gestational weight gain and perinatal outcomes. Study design: Data from the Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-To-Be (NuMoM2b) study were used. Total gestational weight gain was categorized as inadequate, adequate, or excessive based on the 2009 Institute of Medicine guidelines. Outcomes examined included hypertensive disorders of pregnancy, mode of delivery, shoulder dystocia, large for gestational age or small for-gestational age birth weight, and neonatal intensive care unit admission. Results: Among 8,628 women, 1,666 (19.3%) had inadequate, 2,945 (34.1%) had adequate, and 4,017 (46.6%) had excessive gestational weight gain. Excessive gestational weight gain was associated with higher odds of hypertensive disorders (adjusted odds ratio [aOR] = 2.05, 95% confidence interval [CI]: 1.78-2.36) Cesarean delivery (aOR = 1.24, 95% CI: 1.09-1.41), and large for gestational age birth weight (aOR = 1.49, 95% CI: 1.23-1.80), but lower odds of small for gestational age birth weight (aOR = 0.59, 95% CI: 0.50-0.71). Conversely, inadequate gestational weight gain was associated with lower odds of hypertensive disorders (aOR = 0.75, 95% CI: 0.62-0.92), Cesarean delivery (aOR = 0.77, 95% CI: 0.65-0.92), and a large for gestational age birth weight (aOR = 0.72, 95% CI: 0.55-0.94), but higher odds of having a small for gestational age birth weight (aOR = 1.64, 95% CI: 1.37-1.96). Conclusion: Both excessive and inadequate gestational weight gain are associated with adverse maternal and neonatal outcomes.Item Pregnancy as a Window to Future Cardiovascular Health: Design and Implementation of the nuMoM2b Heart Health Study(Oxford University Press, 2016-03-15) Haas, David M.; Ehrenthal, Deborah B.; Koch, Matthew A.; Catov, Janet M.; Barnes, Shannon E.; Facco, Francesca; Parker, Corette B.; Mercer, Brian M.; Bairey-Merz, C. Noel; Silver, Robert M.; Wapner, Ronald J.; Simhan, Hyagriv N.; Hoffman, Matthew K.; Grobman, William A.; Greenland, Philip; Wing, Deborah A.; Saade, George R.; Parry, Samuel; Zee, Phyllis C.; Reddy, Uma M.; Pemberton, Victoria L.; Burwen, Dale R.; Department of Obstetrics and Gynecology, IU School of MedicineThe National Institute of Child Health and Human Development's Nulliparous Pregnancy Outcomes Study-Monitoring Mothers-to-Be (nuMoM2b) Heart Health Study (HHS) was designed to investigate the relationships between adverse pregnancy outcomes and modifiable risk factors for cardiovascular disease. The ongoing nuMoM2b-HHS, which started in 2013, is a prospective follow-up of the nuMoM2b cohort, which included 10,038 women recruited between 2010 and 2013 from 8 centers across the United States who were initially observed over the course of their first pregnancies. In this report, we detail the design and study procedures of the nuMoM2b-HHS. Women in the pregnancy cohort who consented to be contacted for participation in future studies were approached at 6-month intervals to ascertain health information and to maintain ongoing contact. Two to 5 years after completion of the pregnancy documented in the nuMoM2b, women in the nuMoM2b-HHS were invited to an in-person study visit. During this visit, they completed psychosocial and medical history questionnaires and had clinical measurements and biological specimens obtained. A subcohort of participants who had objective assessments of sleep-disordered breathing during pregnancy were asked to repeat this investigation. This unique prospective observational study includes a large, geographically and ethnically diverse cohort, rich depth of phenotypic information about adverse pregnancy outcomes, and clinical data and biospecimens from early in the index pregnancy onward. Data obtained from this cohort will provide mechanistic and clinical insights into how data on a first pregnancy can provide information about the potential development of subsequent risk factors for cardiovascular disease.Item Pregnancy outcomes and anxiety in nulliparous women(Taylor & Francis, 2022) Gimbel, Lauren A.; Blue, Nathan R.; Allshouse, Amanda A.; Silver, Robert M.; Gimbel, Bruce; Grobman, William A.; Haas, David M.; Simhan, Hyagriv N.; Mercer, Brian M.; Hatfield, Tamera; Obstetrics and Gynecology, School of MedicineObjective: To examine pregnancy outcomes in women with treated and untreated anxiety in a well-characterized cohort. Study design: Secondary analysis of the NuMoM2b study, a prospective multi-center cohort of nulliparous women. Anxiety was assessed at 6 weeks 0 days - 13 weeks 6 days using the State Trait Anxiety Inventory (STAI-T). Women were divided into three groups: anxiety and medical treatment, anxiety and no medical treatment, and no anxiety (controls). The primary outcome was a composite of preterm birth, small for gestational age infant, placental abruption (clinically diagnosed), and hypertensive disorders of pregnancy. Multivariable logistic regression was used to adjust for potential confounding variables. Results: Among 8293 eligible women, 24% (n = 1983) had anxiety; 311 were treated medically. The composite outcome (preterm birth, small for gestational age infant, placental abruption, hypertensive disorders of pregnancy) occurred more often in women with untreated anxiety than controls (28.6% vs 25.9%, p=.02), with no difference between treated anxiety and controls (27.7% vs 25.9%, p=.49). After adjustment for confounders, including controlling for depression, there were no differences in the primary outcome among groups. Untreated anxiety remained associated with increased odds of neonatal intensive care unit admission. Conclusion: Anxiety occurred in almost a quarter of nulliparas. There was no association between treated or untreated anxiety and our primary outcome of adverse pregnancy outcomes after adjustment for confounders. However, neonates born to women with untreated anxiety were at increased risk for NICU admission.Item Prescription and Other Medication Use in Pregnancy(Wolters Kluwer, 2018-05) Haas, David M.; Marsh, Derek J.; Dang, Danny T.; Parker, Corette B.; Wing, Deborah A.; Simhan, Hyagriv N.; Grobman, William A.; Mercer, Brian M.; Silver, Robert M.; Hoffman, Matthew K.; Parry, Samuel; Iams, Jay D.; Caritis, Steve N.; Wapner, Ronald J.; Esplin, M. Sean; Elovitz, Michal A.; Peaceman, Alan M.; Chung, Judith; Saade, George R.; Reddy, Uma M.; Obstetrics and Gynecology, School of MedicineOBJECTIVE: To characterize prescription and other medication use in a geographically and ethnically diverse cohort of women in their first pregnancy. METHODS: In a prospective, longitudinal cohort study of nulliparous women followed through pregnancy from the first trimester, medication use was chronicled longitudinally throughout pregnancy. Structured questions and aids were used to capture all medications taken as well as reasons they were taken. Total counts of all medications taken including number in each category and class were captured. Additionally, reasons the medications were taken were recorded. Trends in medications taken across pregnancy and in the first trimester were determined. RESULTS: Of the 9,546 study participants, 9,272 (97.1%) women took at least one medication during pregnancy with 9,139 (95.7%) taking a medication in the first trimester. Polypharmacy, defined as taking at least five medications, occurred in 2,915 (30.5%) women. Excluding vitamins, supplements, and vaccines, 73.4% of women took a medication during pregnancy with 55.1% taking one in the first trimester. The categories of drugs taken in pregnancy and in the first trimester include the following: gastrointestinal or antiemetic agents (34.3%, 19.5%), antibiotics (25.5%, 12.6%), and analgesics (23.7%, 15.6%, which includes 3.6%; 1.4% taking an opioid pain medication). CONCLUSION: In this geographically and ethnically diverse cohort of nulliparous pregnant women, medication use was nearly universal and polypharmacy was common.
