    Association between aspirin use during pregnancy and cardiovascular risk factors 2-7 years after delivery: The nuMoM2b Heart Health Study
    (Elsevier, 2022) Theilen, Lauren H.; Greenland, Philip; Varagic, Jasmina; Catov, Janet; Shanks, Anthony L.; Thorsten, Vanessa; Parker, Corette B.; McNeil, Rebecca; Mercer, Brian; Hoffman, Matthew; Wapner, Ronald; Haas, David; Simhan, Hyagriv; Grobman, William; Chung, Judith H.; Levine, Lisa D.; Barnes, Shannon; Merz, Noel Bairey; Saade, George; Silver, Robert M.; Obstetrics and Gynecology, School of Medicine
    Objectives: To evaluate the association between aspirin use during first pregnancy and later maternal cardiovascular risk. Study design: In this secondary analysis of a prospective cohort, we included participants who carried their first pregnancy to 20 + weeks, had data regarding aspirin use, and attended a study visit 2-7 years following delivery. The exposure was aspirin use during the first pregnancy. We calculated aspirin use propensity scores from logistic regression models including baseline variables associated with aspirin use in pregnancy and cardiovascular risk. Outcomes of interest were incident cardiovascular-related diagnoses 2-7 years following delivery. Robust Poisson regression calculated the risk of outcomes by aspirin exposure, adjusting for the aspirin use propensity score. Main outcome measures: The primary outcome was a composite of incident cardiovascular diagnoses at the time of the study visit: cardiovascular events, chronic hypertension, metabolic syndrome, prediabetes or type 2 diabetes, dyslipidemia, and chronic kidney disease. Results: Of 4,480 women included, 84 (1.9%) reported taking aspirin during their first pregnancy. 52.6% of participants in the aspirin-exposed group and 43.0% in the unexposed group had the primary outcome. After adjusting for the aspirin use propensity scores, aspirin use during the first pregnancy was not associated with any of the outcomes. Conclusion: We did not detect an association between aspirin use during the first pregnancy and cardiovascular-related diagnoses 2-7 years later. Our study was only powered to detect a large difference in relative risk, so we cannot rule out a smaller difference that may be clinically meaningful.

    Association of a Mediterranean Diet Pattern With Adverse Pregnancy Outcomes Among US Women
    (American Medical Association, 2022-12-01) Makarem, Nour; Chau, Kristi; Miller, Eliza C.; Gyamfi-Bannerman, Cynthia; Tous, Isabella; Booker, Whitney; Catov, Janet M.; Haas, David M.; Grobman, Wiliam A.; Levine, Lisa D.; McNeil, Rebecca; Merz, C. Noel Bairey; Reddy, Uma; Wapner, Ronald J.; Wong, Melissa S.; Bello, Natalie A.; Obstetrics and Gynecology, School of Medicine
    Importance: The Mediterranean diet pattern is inversely associated with the leading causes of morbidity and mortality, including metabolic diseases and cardiovascular disease, but there are limited data on its association with adverse pregnancy outcomes (APOs) among US women. Objective: To evaluate whether concordance to a Mediterranean diet pattern around the time of conception is associated with lower risk of developing any APO and individual APOs. Design, setting, and participants: This prospective, multicenter, cohort study, the Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-Be, enrolled 10 038 women between October 1, 2010, and September 30, 2013, with a final analytic sample of 7798 racially, ethnically, and geographically diverse women with singleton pregnancies who had complete diet data. Data analyses were completed between June 3, 2021, and April 7, 2022. Exposures: An Alternate Mediterranean Diet (aMed) score (range, 0-9; low, 0-3; moderate, 4-5; and high, 6-9) was computed from data on habitual diet in the 3 months around conception, assessed using a semiquantitative food frequency questionnaire. Main outcomes and measures: Adverse pregnancy outcomes were prospectively ascertained and defined as developing 1 or more of the following: preeclampsia or eclampsia, gestational hypertension, gestational diabetes, preterm birth, delivery of a small-for-gestational-age infant, or stillbirth. Results: Of 7798 participants (mean [SD] age, 27.4 [5.5] years), 754 (9.7%) were aged 35 years or older, 816 (10.5%) were non-Hispanic Black, 1294 (16.6%) were Hispanic, and 1522 (19.5%) had obesity at baseline. The mean (SD) aMed score was 4.3 (2.1), and the prevalence of high, moderate, and low concordance to a Mediterranean diet pattern around the time of conception was 30.6% (n=2388), 31.2% (n=2430), and 38.2% (n=2980), respectively. In multivariable models, a high vs low aMed score was associated with 21% lower odds of any APO (adjusted odds ratio [aOR], 0.79 [95% CI, 0.68-0.92]), 28% lower odds of preeclampsia or eclampsia (aOR, 0.72 [95% CI, 0.55-0.93]), and 37% lower odds of gestational diabetes (aOR, 0.63 [95% CI, 0.44-0.90]). There were no differences by race, ethnicity, and prepregnancy body mass index, but associations were stronger among women aged 35 years or older (aOR, 0.54 [95% CI, 0.34-0.84]; P = .02 for interaction). When aMed score quintiles were evaluated, similar associations were observed, with higher scores being inversely associated with the incidence of any APO. Conclusions and relevance: This cohort study suggests that greater adherence to a Mediterranean diet pattern is associated with lower risk of APOs, with evidence of a dose-response association. Intervention studies are needed to assess whether dietary modification around the time of conception can reduce risk of APOs and their downstream associations with future development of cardiovascular disease risk factors and overt disease.

    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.
