The purpose of this research study is to estimate the future cardiovascular disease risk in pregnant women and their infants. We will use questionnaires, maternal and infant central pulse wave velocity (PWV) which is a measure of arterial stiffness (vascular aging) that predicts cardiovascular disease. This non-invasive instrument is totally safe in pregnancy. By measuring the time it takes for blood leaving your heart to reach your leg with the use of 2 small cuffs, it is able to determine arterial stiffness which is a key component of cardiovascular disease.

The purpose of the SUNBEAM study is to learn more about factors that put babies and toddlers at higher risk for developing food allergies and eczema. This is an observational study, where we will follow pregnant mothers and their babies from birth to 3 years to learn more about how allergies develop. We are doing this research because there are currently no reliable ways to predict which children will develop food allergies.

The P3 Study is also known as the Path to Prevent Preterm Birth Study. This study collects detailed data and biologic samples. It will help researchers to understand why some women have more than one preterm birth. For example, information from this study may help doctors know which medications or medical care will work best to help women deliver full term. We hope that this research will help improve outcomes for moms and babies in North Carolina and beyond! We are including women who have had a previous preterm birth. We are also asking some women who have delivered only full term babies to participate.

The purpose of this study is to investigate the health of former women's soccer players.

About 1 out of 5 women who are overweight or report snoring will test positive for sleep apnea during pregnancy. The most commonly prescribed treatment for sleep apnea is a small device called a CPAP. The CPAP just helps you to breathe in a normal pattern during sleep. Sleep apnea is common in pregnancy; it can affect the quality of your sleep and how you feel and function during the day. The goal of this study is to understand if using CPAP in pregnancy can help women have healthier pregnancies.

The goal of this study is to uncover the frequency of low oxygen levels during sleep in pregnant women that have severe sickle cell disease. These women have a high risk of complications during pregnancy, and low oxygen levels might contribute to the complications. Therefore, finding and treating low oxygen can be impactful. The study will also look at blood cells and assess how low oxygen affects them.

this study is to gather data on activity and activity restrictions for women pregnant with a short cervix.
