Brief Summary

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.

Study Population

The study population consists of a racially/ethnically/geographically diverse population of 10,038 nulliparous pregnant women with singleton gestations recruited through 8 participating clinical sites and their subsites.

You may qualify if:

  • Nullipara - Pregnant women with no prior pregnancy lasting 20 weeks 0 days or greater.
  • Viable singleton gestation - a single living fetus with fetal cardiac activity at the most recent ultrasound before enrollment
  • Between 6 weeks 0 days and 13 weeks 6 days project estimated gestational age (EGA) at first study visit.
  • Intend to deliver at a participating hospital.

You may not qualify if:

  • Participant age \<13 years.
  • History of 3 or more spontaneous abortions.
  • Fetal malformation evident at or before enrollment that is likely lethal (e.g., anencephaly, hydrops, diffuse subcutaneous edema or cystic hygroma, ectopic cordis, encephalocele).
  • Known fetal aneuploidy (based on chorionic villus sampling).
  • Surrogate pregnancy (donor oocyte pregnancy).
  • Multifetal reduction.
  • Participating in an intervention study that is anticipated to influence maternal or fetal morbidities/mortality unless it is determined before enrollment that the study code will be made available.
  • Woman previously enrolled in this study, including those consented but delivered before 20 weeks 0 days gestation.
  • Planned pregnancy termination.
  • Unable to provide informed consent.
