Impact of Low Maternal Weight on Pregnancy and Neonatal Outcomes.

Objective: To examine the effect of underweight maternal body mass index (BMI) on pregnancy complications and neonatal outcomes.

Design: Cohort study.

Setting: Tertiary academic center.

Neighborhood disadvantage and general anesthesia utilization in cesarean delivery: a retrospective analysis.

Background: Neighborhood disadvantage, a social driver of health (SDOH), has been associated with adverse perinatal outcomes; yet little is known about its association with anesthetic choice.

Objective: The purpose of this study is to assess the association of neighborhood disadvantage and anesthetic choice for cesarean deliveries. We hypothesize that people from the most disadvantaged neighborhoods are more likely to receive general anesthesia for cesarean deliveries compared to those from the most advantaged neighborhoods.

Maternal Lipids in Pregnancy and Later Life Dyslipidemia: The POUCHmoms Longitudinal Cohort Study.

Objective: Maternal lipid levels increase in normal pregnancies. Here, we examine whether pregnancies with the highest total cholesterol, low-density lipoprotein (LDL) or triglyceride levels or the lowest high-density lipoprotein (HDL) levels predict future dyslipidemia post-pregnancy.

Design: Longitudinal cohort study.

Pre-pregnancy substance use and first trimester cardiovascular health among nulliparous pregnant people: The nuMoM2b Study.

Background: Suboptimal pre-pregnancy health, including substance use and cardiovascular risk factors, is associated with higher risks of maternal-foetal morbidity and mortality.

Objective: To determine if pre-pregnancy substance use is associated with early pregnancy cardiovascular health (CVH). It is hypothesised that pre-pregnancy use of substances is associated with worse CVH in the first trimester of pregnancy.

Periconceptional Dietary Quality and Metabolic Syndrome at 3 Years Postpartum.

Background: The period around pregnancy is a critical window in the primordial prevention of cardiovascular disease, but little is known about the role of dietary patterns in cardiometabolic health. Our objective was to determine the association between alignment of periconceptional diet with the 2020 to 2025 Dietary Guidelines for Americans and the risk of metabolic syndrome.

Methods And Results: We used data from the Nulliparous Pregnancy Outcomes Study: monitoring mothers-to-Be Heart Health Study, a pregnancy cohort study that followed pregnant participants to a median of 3 years postpartum (n=4423).

Association of Gestational Diabetes With Subclinical Cardiovascular Disease.

Background: Gestational diabetes mellitus (GDM) is associated with increased long-term risk of cardiovascular disease but the cardiovascular structural and functional changes that contribute to risk are not well understood.

Objectives: The purpose of this study was to determine whether GDM is associated with adverse cardiac remodeling and endothelial dysfunction a decade after delivery, independent of type 2 diabetes.

Methods: Women with deliveries between 2008 and 2009 were initially selected from a prospective clinical cohort.

Association of Hypertensive Disorders of Pregnancy With Coronary Microvascular Dysfunction 8 to 10 Years After Delivery.

Background: Hypertensive disorders of pregnancy (HDP) are associated with subsequent adverse cardiac remodeling and cardiovascular disease. The role of myocardial microvascular disease among individuals with HDP and left ventricular (LV) remodeling as a potential link to cardiovascular disease is unknown. We aimed to determine whether individuals with HDP history have coronary microvascular dysfunction measured by coronary flow reserve 8 to 10 years after delivery and whether microvascular dysfunction correlates with LV remodeling.

Inflammatory, metabolic, and endothelial biomarkers before and after pregnancy complications.

Women with gestational diabetes mellitus (GDM), hypertensive disorders of pregnancy (HDP), and preterm birth (PTB) have excess cardiovascular disease compared with those with uncomplicated births, perhaps related to prepregnancy inflammation, dysmetabolism, or endothelial dysfunction. We included 1238 women in the Coronary Artery Risk Development in Young Adults Study (1985-2011) with 2215 births classified according to outcomes (term, uncomplicated births were the referent). Using repeated measures analysis of variance, we estimated prepregnancy and postpregnancy biomarkers, as well as biomarker change according to pregnancy outcomes, adjusted for confounders.

The sedentary behavior reduction in pregnancy intervention (SPRING) pilot and feasibility randomized trial.

Pregnant individuals rarely achieve moderate-to-vigorous intensity physical activity recommendations.Purpose The sedentary behavior reduction in pregnancy intervention (SPRING) pilot and feasibility randomized trial aimed to demonstrate feasibility, acceptability, and initial efficacy of a lower intensity intervention targeting reduced sedentary behavior and increased standing and steps.Methods First trimester pregnant individuals at risk for high sedentary behavior and adverse pregnancy outcomes (APO) were randomized 2:1 to a multi-component sedentary behavior reduction intervention or no-contact control.

Associations of Physical Activity and Sedentary Behaviors with Depressive Symptoms and Mood Disturbance Throughout Pregnancy.

Mental health is critical for a healthy pregnancy, yet few studies have evaluated its associations with best practice, objectively measured moderate- to vigorous-intensity physical activity (MVPA) or sedentary behavior (SED). This study evaluated associations of MVPA and SED with mental health across pregnancy. Two cohort studies (total  = 125, mean [standard deviation] 31 [5] years, and 14.

Blood Pressure Trajectories Through the First Year Postpartum in Overweight or Obese Individuals Following a Hypertensive Disorder of Pregnancy.

Background: Hypertensive disorders of pregnancy are associated with cardiovascular disease; however, patterns of blood pressure (BP) recovery are understudied. We compared pregnancy and postpartum BP trajectories among individuals with hypertensive disorders of pregnancy who developed persistent hypertension at 1-year postpartum compared with individuals with normalization of BP.

Methods: We used data from a randomized clinical trial of individuals with overweight, obesity, and hypertensive disorders of pregnancy conducted in the first year after delivery.

A novel technique to estimate intravillous fetal vasculature on routine placenta histologic sections.

Placental histopathologic lesions are dichotomized into "present" or "absent" and have limited inter-rater reliability. Continuous metrics are needed to characterize placental health and function. Tissue sections (N = 64) of human placenta were stained with CD34 antibody and hematoxylin.

Neighborhood Deprivation, Perceived Stress, and Pregnancy-Related Hypertension Phenotypes a Decade Following Pregnancy.

Background: Hypertensive disorders in pregnancy and other adverse pregnancy outcomes (APOs) increase the risk of developing chronic hypertension and cardiovascular disease. Perceptions of stress and neighborhood context also influence blood pressure (BP) fluctuations. We examined if APOs, higher perceived stress, and neighborhood deprivation were associated with hypertension phenotypes a decade after pregnancy in untreated individuals.

Maternal Mental Health, COVID-19-Related Distress, and Disruptions in Lifestyle Behaviors Among Postpartum Mothers With a Previous Hypertensive Disorder of Pregnancy.

Background: Many perinatal people experienced pandemic-related distress and changes in health behaviors at the onset of the COVID-19 pandemic, but less is known about how the pandemic continued to impact their health.

Objective: The authors of this study examined the influence of pandemic-related distress and maternal mental health on postpartum lifestyle behaviors of mothers with a previous hypertensive disorder of pregnancy.

Methods: Between September 2021 and March 2022, 82 postpartum (19.

Characteristics of Premature Myocardial Infarction Among Women With Prior Adverse Pregnancy Outcomes.

Background: Adverse pregnancy outcomes (APOs), hypertensive disorders of pregnancy, gestational diabetes mellitus, and preterm birth are associated with ischemic heart disease in later life.

Objectives: The authors aimed to study the features of premature myocardial infarction (MI) among women with and without prior APOs.

Methods: We performed a retrospective analysis of women with premature MI (<65 years of age) referred for left heart catheterization matched with a database of abstracted pregnancy data.

Rationale, Design, and Methods for the Sedentary Behavior Reduction in Pregnancy Intervention (SPRING): Protocol for a Pilot and Feasibility Randomized Controlled Trial.

Background: Adverse pregnancy outcomes (APOs) identify cardiovascular disease risk, but few effective interventions are available. High sedentary behavior (SED) has recently been associated with APOs, but very few randomized controlled trials (RCTs) have tested SED reduction in pregnancy.

Objective: The Sedentary Behavior Reduction in Pregnancy Intervention (SPRING) pilot and feasibility RCT addresses this gap by testing the feasibility, acceptability, and preliminary pregnancy health effects of an intervention to reduce SED in pregnant women.

Prepregnancy obesity and risk of placental inflammation at term: a selection bias analysis.

Purpose: Placental histopathology is a resource for investigating obesity-associated pregnancy conditions. However, studies oversample adverse pregnancies, biasing findings. We examine the association between prepregnancy obesity (risk factor for inflammation) and histologic placental inflammation (correlated with impaired infant neurodevelopment) and how selection bias may influence the association.
