    (Elsevier, 2023) Meislin, Rachel; Bose, Sonali; Huang, Xiaoning; Wharton, Robert; Ponce, Jana; Simhan, Hyagriv; Haas, David; Saade, George; Silver, Robert; Chung, Judith; Mercer, Brian M.; Grobman, William A.; Khan, Sadiya S.; Bianco, Angela; Obstetrics and Gynecology, School of Medicine
    Objective:: Asthma is one of the most common comorbid conditions in pregnancy. While asthma has been identified as an independent risk factor for cardiovascular disease in the general population, the influence of active asthma during pregnancy on future cardiac risk is unclear. Growing evidence has linked maternal active asthma to adverse pregnancy outcomes (APOs), such as hypertensive disorders of pregnancy (HDP), including preeclampsia which is a well-defined risk factor for future cardiovascular disease including altered cardiac structure and diastolic dysfunction. A thorough understanding of the relationship between pre-existing asthma and APOs may be instrumental in identifying upstream factors contributing to lifetime maternal cardiovascular risk. However, current knowledge of these relationships has been largely derived from retrospective clinical studies, which limit the precision of capturing APOs. Therefore, we investigated associations between pre-existing asthma and individual subtypes of APOs in a secondary analysis of a prospective multi-center cohort of nulliparous individuals with rigorously adjudicated pregnancy outcomes. Study design:: We included participants from the multisite Nulliparous Outcomes in Pregnancy: Monitoring Mothers to be (nuMom2b) cohort, which recruited nulliparous individuals with a viable, singleton gestation between 60/7 and 136/7 weeks. Details of the study design have been previously described, which included medical histories in standardized interviews. This secondary analysis included individuals aged 18 years or older with a live birth and excluded those with a history of pre-pregnancy hypertension or diabetes. For the purposes of this analysis, we defined active asthma as a self-reported history of asthma and on current asthma treatment, including use of bronchodilator, inhaled steroid, or immune modulator, captured at the first trimester visit. The primary outcome was HDP and secondary outcomes included other APOs. Characteristics between participants who did and did not have asthma were compared. Univariate and multivariate logistic regression, described using odds ratios (ORs) and adjusted ORs (aORs) and 95% confidence intervals (95% CI), was used to determine risk of APOs. Models were adjusted for maternal age, study site, insurance type (marker of socioeconomic status), and smoking status at the first trimester visit. Race/ethnicity and body mass index (BMI) were excluded from fully adjusted models as race/ethnicity was considered as a factor reflective of the social determinants of health and BMI was conceptualized as within the casual pathway for developing HDP. The study was approved by all local institutional review boards, and participants gave written informed consent. Analyses were conducted using STATA (MP 17, College Station, TX). Results: Of 8,741 individuals included, 1,521 (17.4%) reported a diagnosis of asthma at the first trimester visit, of whom 588 (38.7%) reported the use of any asthma medication. When comparing participants with and without asthma, a higher proportion of those with asthma reported smoking tobacco in the three months prior to pregnancy (20.7% vs 16.5%) (Table 1). Univariate logistic regression revealed that a diagnosis of asthma was associated with a significantly higher risk of HDP (OR: 1.21 [1.04, 1.42]). Following adjustment, risk of HDP remained significantly higher (aOR: 1.23 [1.06, 1.42]), specifically preeclampsia (aOR: 1.21, [1.02, 1.45]). Secondary analyses in participants with active asthma (ie additional reported use of asthma medication during or before the first trimester) demonstrated a significantly higher risk of HDP (aOR 1.32 [1.06–1.65]) including preeclampsia (aOR 1.27 [1.07–1.51]; in addition to spontaneous preterm birth (aOR 1.60 [1.30–1.96]). Conclusions: In a diverse, nationally representative sample of nulliparous individuals,, a diagnosis of asthma was associated with a significantly higher risk of HDP. Active asthma increased the risk of both spontaneous preterm birth and HDP. This analysis supports the importance of identifying active asthma as a risk factor for APOs associated with a higher risk of future cardiovascular disease.

    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 Medicine
    Objective: 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.

    The impact of setting a pregnancy weight gain goal on total weight gain
    (Wiley, 2021) Bodnar, Lisa M.; Abrams, Barbara; Simhan, Hyagriv N.; Scifres, Christina M.; Silver, Robert M.; Parry, Samuel; Crosland, Brian A.; Chung, Judith; Himes, Katherine P.; Obstetrics and Gynecology, School of Medicine
    Background: Expert groups recommend that women set a pregnancy weight gain goal with their care provider to optimise weight gain. Objective: Our aim was to describe the concordance between first-trimester personal and provider pregnancy weight gain goals with the Institute of Medicine (IOM) recommendations and to determine the association between these goals and total weight gain. Methods: We used data from 9353 women in the Nulliparous Pregnancy Outcomes Study: monitoring mothers-to-be. In the first trimester, women reported their personal pregnancy weight gain goal and their provider weight gain goal, and we categorised personal and provider weight gain goals and total weight gain according to IOM recommendations. We used log-binomial or linear regression models to relate goals to total weight gain, adjusting for confounders including race/ethnicity, maternal age, education, smoking, marital status and planned pregnancy. Results: Approximately 37% of women reported no weight gain goals, while 24% had personal and provider goals, 31% had only a personal goal, and 8% had only a provider goal. Personal and provider goals were outside the recommended ranges in 12%-23% of normal-weight women, 31%-41% of overweight women and 47%-63% of women with obesity. Women with both personal and provider pregnancy weight gain goals were 6%-14% more likely than their counterparts to have a goal within IOM-recommended ranges. Having any goal or a goal within the IOM-recommended ranges was unrelated to pregnancy weight gain. Excessive weight gain occurred in approximately half of normal-weight or obese women and three-quarters of overweight women, regardless of goal setting group. Conclusions: These findings do not support the effectiveness of early-pregnancy personal or provider gestational weight gain goal setting alone in optimising weight gain. Multifaceted interventions that address a number of mediators of goal setting success may assist women in achieving weight gain consistent with their goals.

    Neighborhood Socioeconomic Disadvantage and Abnormal Birth Weight
    (Wolters Kluwer, 2023) Venkatesh, Kartik K.; Yee, Lynn M.; Johnson, Jasmine; Wu, Jiqiang; McNeil, Becky; Mercer, Brian; Simhan, Hyagriv; Reddy, Uma M.; Silver, Robert M.; Parry, Samuel; Saade, George; Chung, Judith; Wapner, Ronald; Lynch, Courtney D.; Grobman, William A.; Obstetrics and Gynecology, School of Medicine
    Objective: To examine whether exposure to community or neighborhood socioeconomic disadvantage as measured by the ADI (Area Deprivation Index) is associated with risk of abnormal birth weight among nulliparous individuals with singleton gestations. Methods: This was a secondary analysis from the prospective cohort NuMoM2b study (Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-To-Be). Participant addresses at cohort enrollment between 6 and 13 weeks of gestation were geocoded at the Census tract level and linked to the 2015 ADI. The ADI, which incorporates the domains of income, education, employment, and housing quality into a composite national ranking of neighborhood socioeconomic disadvantage, was categorized by quartiles (quartile 1, least disadvantaged, reference; quartile 4, most disadvantaged). Outcomes were large for gestational age (LGA; birth weight at or above the 90th percentile) and small for gestational age (SGA; birth weight below the 10th percentile) compared with appropriate for gestational age (AGA; birth weight 10th-90th percentile) as determined with the 2017 U.S. natality reference data, standardized for fetal sex. Multinomial logistic regression models were adjusted for potential confounding variables. Results: Of 8,983 assessed deliveries in the analytic population, 12.7% (n=1,143) were SGA, 8.2% (n=738) were LGA, and 79.1% (n=7,102) were AGA. Pregnant individuals living in the highest ADI quartile (quartile 4, 17.8%) had an increased odds of delivering an SGA neonate compared with those in the lowest referent quartile (quartile 1, 12.4%) (adjusted odds ratio [aOR] 1.32, 95% CI 1.09-1.55). Pregnant individuals living in higher ADI quartiles (quartile 2, 10.3%; quartile 3, 10.7%; quartile 4, 9.2%) had an increased odds of delivering an LGA neonate compared with those in the lowest referent quartile (quartile 1, 8.2%) (aOR: quartile 2, 1.40, 95% CI 1.19-1.61; quartile 3, 1.35, 95% CI 1.09-1.61; quartile 4, 1.47, 95% CI 1.20-1.74). Conclusion: Neonates of nulliparous pregnant individuals living in U.S. neighborhoods with higher area deprivation were more likely to have abnormal birth weights at both extremes.

    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 Medicine
    OBJECTIVE: 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.
