The overall objective of this proposal is to conduct a longitudinal prospective study of overweight/obese (OW/OB) pregnant women and their offspring to determine which prenatal exercise mode will have the greatest impact on maternal and infant cardiometabolic health. This information may lead to clinical practice recommendations that improve childhood health. This randomized controlled trial will recruit 284 OW/OB pregnant women randomized to an exercise intervention (aerobic (AE), resistance (RE), or aerobic+resistance exercise (AERE)) or to no exercise; their infants will be measured at 1, 6, and 12 months of age. This design will test our central hypothesis that AERE and RE training during pregnancy will improve maternal and offspring cardiometabolic outcomes to a greater extent than AE alone. This hypothesis will be tested with two specific aims: Aim 1. Determine the influence of different exercise modes during OW/OB pregnancy on infant cardiometabolic health and growth trajectories. Hypothesis: AE, RE, and AERE by OW/OB pregnant women will improve offspring neuromotor and cardiometabolic measures at 1, 6, and 12 months postpartum (e.g. decreased %body fat, BMI z-score, heart rate [HR], non-HDL, and C-Reactive Protein (CRP); increased insulin sensitivity) compared to infants of OW/OB pregnant women that do not exercise; AERE and RE will have the greatest impact on improving infant measures. Aim 2. Determine the most effective exercise mode in OW/OB pregnancy on improving maternal cardiometabolic health outcomes. Hypothesis: AE, RE, and AERE by OW/OB pregnant women will improve both maternal cardiometabolic health measures (e.g. decreased BMI z-score, non-HDL, % body fat, HR, weight gain) across pregnancy (16-36 weeks' gestation) and overall pregnancy outcomes (e.g. lower incidence of gestational diabetes, pre-eclampsia, hypertension during gestation) compared to OW/OB pregnant women that do not exercise; AERE and RE will have the greatest impact on improving maternal health measures, with the AERE group having the highest compliance. The proposed study will be the first to provide an understanding of the influence of maternal exercise modes on the cardiometabolic health and growth trajectories of offspring who are at increased risk due to maternal OW/OB. This work will have a significant impact on reducing the cycle of OB, potentially providing the earliest and most efficacious intervention to decrease or prevent OB in the next generation. Read Less

The goal of Advanced Fetal Imaging - Phase II is to advance fetal MRI imaging by designing MRI coils specifically for pregnant women and testing recently developed MRI image acquisition techniques. The investigators aim to more reliably obtain higher quality fetal MRI images when compared to current clinical fetal MRI. Read Less

The P3OPPY Project is one of five projects within the American Heart Association P3 EQUATE Network. The overarching goal of the P3 EQUATE American Heart Association Health Equity Research Network (HERN) is to promote equity in Maternal and Infant Health outcomes by identifying innovative and cost-effective strategies to enhance access to quality health information, care, and experiences during pregnancy, postnatal and postpartum/preconception periods, particularly for Black and under-served populations. Collectively, the investigators will collaborate with pregnant and postpartum individuals and their families, hospitals, and communities to discover ways to reduce racism and social problems that contribute to poor health outcomes.

This study utilizes infusions of kisspeptin in healthy women to isolate the impact of kisspeptin on beta-cell responsivity assessed by the mixed meal tolerance test. Read Less

During pregnancy, gestational diabetes increases the risk of complications and adverse outcomes for mother and child, however about 50% of gestational diabetes cases are diagnosed without a known risk factor present. This project uses both a large sample retrospective study, and a prospective study to help us understand the mechanisms by which mental health and stress impact glucose metabolization during pregnancy and delineate their contribution to gestational diabetes and racial disparities. The investigators expect, to improve the ability to identify women at risk, and advance options for preventative care and treatment, decreasing the impact of gestational diabetes and related complications.

The purpose of the OTIS Autoimmune Diseases in Pregnancy Study is to monitor planned and unplanned pregnancies exposed to certain medications, to evaluate the possible teratogenic effect of these medications and to follow live born infants for one year after birth. With respect to fetal outcome, it is important to evaluate the spectrum of outcomes that may be relevant to a medication exposure during pregnancy, and these include both easily recognizable defects which are visible at birth, as well as more subtle or delayed defects that may not be readily identifiable without special expertise and observation beyond the newborn period.

This study plans to learn more about how an omega-3 fatty acid supplement effects triglyceride levels in pregnancy. Triglycerides are a type of fat found in your blood. Your body converts extra calories into triglycerides to be stored and used later for energy. It is normal for triglyceride levels to go up during pregnancy however some women have levels that are ~30-40% higher than normal when they reach their third trimester of pregnancy. Having high triglycerides in pregnancy may be related to an increased chance of having a baby that is large for their age. The goal of this study is to determine if taking an omega-3 fatty acid supplement can slow the rise in triglyceride levels later in pregnancy. Read Less

This study plans to learn more about how triglyceride levels in pregnancy affect newborn fat mass. Obesity in pregnancy, in the absence of gestational diabetes, is now the most common cause of large-for-gestational-age infants and increased newborn fat mass. Previous data supports the idea that maternal triglycerides, not glucose, are the strongest predictor of both total newborn fat mass and liver fat. In this study, mothers will monitor triglyceride and glucose levels at specific points in pregnancy using point-of-care meters at home. Two weeks after birth, infants will have total fat measured by air-displacement plethysmography (PEAPOD) and liver fat measures by Magnetic Resonance Spectroscopy (MRS). The central hypothesis is that in obesity, fasting triglycerides and postprandial triglycerides will predict newborn fat mass in a free-living environment. Read Less

This is a worldwide, descriptive safety study collecting data on women and their offspring exposed to avalglucosidase alfa during pregnancy and/or lactation, to assess the risks of avalglucsodiase alfa on pregnancy and maternal complications and adverse effects in the developing fetus, neonate, and infant. Outcomes in exposed infants, including growth and development, will be assessed through at least the first year of life. Data will be collected for approximately 10 years. Read Less

The purpose of this study is to examine cognitive and affective outcomes in the offspring of women supplemented with choline vs. control during pregnancy. Read Less
