    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.

    (American Heart Association, 2023) Khan, Sadiya S.; Petito, Lucia C.; Huang, Xiaoning; Harrington, Katharine; McNeil, Rebecca B.; Bello, Natalie A.; Bairey Merz, C. N.; Miller, Eliza C.; Ravi, Rupa; Scifres, Christina; Catov, Janet; Pemberton, Victoria; Varagic, Jasmina; Zee, Phyllis C.; Yee, Lynn M.; Ray, Mitali; Kim, Jin Kyung; Lane-Cordova, Abbi; Lewey, Jennifer; Theilen, Lauren H.; Saade, George R.; Greenland, Philip; Grobman, William A.; Obstetrics and Gynecology, School of Medicine
    Background: Obesity is a well-established risk factor for both adverse pregnancy outcomes (APOs) and cardiovascular disease (CVD). However, it is not known whether APOs are mediators or markers of the obesity-CVD relationship. This study examined the association between body mass index, APOs, and postpartum CVD risk factors. Methods: The sample included adults from the nuMoM2b (Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-To-Be) Heart Health Study who were enrolled in their first trimester (6 weeks-13 weeks 6 days gestation) from 8 United States sites. Participants had a follow-up visit at 3.7 years postpartum. APOs, which included hypertensive disorders of pregnancy, preterm birth, small-for-gestational-age birth, and gestational diabetes, were centrally adjudicated. Mediation analyses estimated the association between early pregnancy body mass index and postpartum CVD risk factors (hypertension, hyperlipidemia, and diabetes) and the proportion mediated by each APO adjusted for demographics and baseline health behaviors, psychosocial stressors, and CVD risk factor levels. Results: Among 4216 participants enrolled, mean±SD maternal age was 27±6 years. Early pregnancy prevalence of overweight was 25%, and obesity was 22%. Hypertensive disorders of pregnancy occurred in 15%, preterm birth in 8%, small-for-gestational-age birth in 11%, and gestational diabetes in 4%. Early pregnancy obesity, compared with normal body mass index, was associated with significantly higher incidence of postpartum hypertension (adjusted odds ratio, 1.14 [95% CI, 1.10-1.18]), hyperlipidemia (1.11 [95% CI, 1.08-1.14]), and diabetes (1.03 [95% CI, 1.01-1.04]) even after adjustment for baseline CVD risk factor levels. APOs were associated with higher incidence of postpartum hypertension (1.97 [95% CI, 1.61-2.40]) and hyperlipidemia (1.31 [95% CI, 1.03-1.67]). Hypertensive disorders of pregnancy mediated a small proportion of the association between obesity and incident hypertension (13% [11%-15%]) and did not mediate associations with incident hyperlipidemia or diabetes. There was no significant mediation by preterm birth or small-for-gestational-age birth. Conclusions: There was heterogeneity across APO subtypes in their association with postpartum CVD risk factors and mediation of the association between early pregnancy obesity and postpartum CVD risk factors. However, only a small or nonsignificant proportion of the association between obesity and CVD risk factors was mediated by any of the APOs, suggesting APOs are a marker of prepregnancy CVD risk and not a predominant cause of postpartum CVD risk.

    Dietary Inflammatory Index Is Differentially Associated With Cardiometabolic Health After Pregnancy on the Basis of Adverse Pregnancy Outcome Exposure
    (American Heart Association, 2024) Jancsura, McKenzie K.; Wirth, Michael D.; Helsabeck, Nathan P.; Mercer, Brian M.; Haas, David M.; Greenland, Philip; McNeil, Rebecca; Levine, Lisa D.; Silver, Robert M.; Yee, Lynn M.; Saade, George R.; Khan, Sadiya S.; Chung, Judith H.; Grobman, William A.; Obstetrics and Gynecology, School of Medicine
    Background: Inflammatory diets may influence risk of cardiovascular disease. Subsequent cardiovascular disease is also influenced by adverse pregnancy outcomes (APOs) such as preterm birth, small-for-gestational-age birth, gestational diabetes, and hypertensive disorders of pregnancy. However, the associations between inflammatory diet, APOs, and cardiometabolic health remain unclear. Methods and results: We used data from the nuMoM2b (Nulliparous Pregnancy Outcomes Study Monitoring Mothers-to-Be) HHS (Heart Health Study) to assess the relationship between dietary quality and cardiometabolic health. We calculated Energy-Adjusted Dietary Inflammatory Index scores representing the inflammatory burden in a person's diet. We used linear regression to determine the association between Energy-Adjusted Dietary Inflammatory Index score and cardiometabolic outcomes. We performed stratified analyses for outcomes with a significant interaction between Energy-Adjusted Dietary Inflammatory Index and APO. Data were available from 3249 participants at a median of 3.1 years after delivery. Higher Energy-Adjusted Dietary Inflammatory Index scores were associated with higher body mass index (B=0.29 kg/m2 [95% CI, 0.16-0.42]), waist circumference (0.66 cm [95% CI, 0.39-0.93]), diastolic blood pressure (0.26 mm Hg [95% CI, 0.09-0.44]), mean arterial pressure (0.23 mm Hg [95% CI, 0.06-0.40]), triglycerides (2.11 mg/dL [95% CI, 1.05-3.18]), creatinine (2.78 mg/dL [95% CI, 1.13-4.44]), insulin (exp[B]=1.04 [95% CI, 1.03-1.05]) and C-reactive protein (exp[B]=1.07 [95% CI, 1.04-1.10]), and lower high-density lipoprotein cholesterol (-0.41 mg/dL [95% CI, -0.66 to -0.37]) (all P<0.01). Significant interactions with APO (P<0.05) were identified for body mass index and waist circumference, with stratified analysis revealing stronger associations for individuals with APOs. Conclusions: A more proinflammatory diet was associated with worse cardiometabolic health measures, and these relationships differed by a person's APO history. Further investigation should establish how dietary modifications after pregnancy may potentially mitigate cardiovascular disease risk.

    Genetic Risk and First-Trimester Cardiovascular Health Predict Hypertensive Disorders of Pregnancy in Nulliparous Women
    (Elsevier, 2025) Mathew, Vineetha; Khan, Raiyan R.; Jowell, Amanda R.; Yan, Qi; Pe'er, Itsik; Truong, Buu; Natarajan, Pradeep; Yee, Lynn M.; Khan, Sadiya S.; Sharma, Garima; Patel, Aniruddh P.; Cho, So Mi Jemma; Pabon, Maria A.; McNeil, Rebecca B.; Spencer, Jillyn; Silver, Robert M.; Levine, Lisa D.; Grobman, William A.; Catov, Janet M.; Haas, David M.; Honigberg, Michael C.; Obstetrics and Gynecology, School of Medicine
    Background: Hypertensive disorders of pregnancy (HDPs) (preeclampsia/eclampsia and gestational hypertension) are a leading cause of maternal and perinatal morbidity and mortality and are associated with long-term maternal cardiovascular disease. High genetic risk and poor cardiovascular health (CVH) are each associated with HDPs, but whether genetic risk for HDP is modified by CVH status in early pregnancy is unknown. Objectives: In this study, the authors sought to test the independent and joint associations of genetic risk and first-trimester CVH with development of HDP. Methods: We examined genotyped participants from the nuMoM2b (Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-Be), a prospective observational cohort that enrolled nulliparous individuals with singleton pregnancies from 2010 to 2013 at 8 U.S. clinical sites. Genetic risk was calculated according to a validated genetic risk score for HDP. A first-trimester CVH score was closely adapted from the American Heart Association Life's Essential 8 model. Genetic risk and CVH were each categorized as low (bottom quintile), intermediate (quintile 2-4), or high (top quintile). The primary outcome was development of HDP. Multivariable-adjusted logistic regression was used to test the independent and joint associations of genetic risk and CVH with development of HDPs. Results: Among 7,499 participants (mean age 27.0 years), the median first-trimester CVH score was 77.1 (Q1-Q3: 67.1-85.7). Overall, 1,032 participants (13.8%) developed an HDP (487 [6.5%] preeclampsia, 545 [7.3%] gestational hypertension). Genetic risk and CVH were each independently and additively associated with HDP (high vs low genetic risk: adjusted OR [aOR]: 2.21 [95% CI: 1.78-2.77; P < 0.001]; low vs high CVH: aOR: 2.92 [95% CI: 2.28-3.74; P < 0.001]). There was no significant interaction between genetic risk and CVH regarding risk of HDPs (Pinteraction > 0.05). HDP incidence ranged from 4.5% (low genetic risk, high CVH) to 25.7% (high genetic risk, low CVH). Compared with low CVH, high CVH was associated with 53%-74% lower risk of HDP across genetic risk strata. Findings were consistent when examining preeclampsia/eclampsia and gestational hypertension separately. Conclusions: Lower genetic risk and higher first-trimester CVH were independently and additively associated with lower risk of developing HDPs in nulliparous individuals. Favorable CVH in early pregnancy may mitigate high genetic risk for HDP.
