Forty percent of pregnant women in the United States are women who have never given birth. As a group, they sometimes have complications with their pregnancy, but there is no information from a previous pregnancy to identify who might have a problem. Very little research has been done with this group. The Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-be (nuMoM2b) is collecting data from a diverse population of about 10,000 women who are having their first baby and are carrying only one baby. The women are enrolled early in pregnancy and undergo research assessments four times during their pregnancies. Data are collected through interviews, self-completed data forms, clinical measurements, ultrasound, and collection and storage of blood samples, urine samples, and fluid from the vagina and cervix. Some information comes from medical records. A subset of women may be asked to participate in substudies collecting information on sleep breathing, sleep patterns and quality, or other areas possibly related to birth outcomes. The goal of the research is to find ways to identify women in this group who might develop a problem with their pregnancy and use this information to improve the health of pregnant women and their babies in the future. The study is focusing on pregnancy problems like high blood pressure, babies that are born much too early and very small babies.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
