Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-be Heart Health Study (nuMoM2b Heart Health Study)

Participants from study sites that recruited during the original study funded by NICHD of pregnant people, called nuMoM2b, participated in this study. The nuMoM2b-HHS1 was a prospective observational follow-up study of the nuMoM2b cohort consisting of interval contacts via phone or web every 6 months to about a year, and an in-person visit 2 to 7 years after the end of the nuMoM2b pregnancy including: Demographics Self-administered questionnaires Clinical measurements Lab results An in-home sleep breathing assessment for the subset of participants with at least one valid sleep breathing assessment during nuMoM2b Abstraction of medical records for pregnancies subsequent to nuMoM2b involving self-reported adverse pregnancy outcomes or multiple births Abstraction of medical records of selected cardiovascular risk-related events or procedures reported by participants. The study capitalized on the rich and unique data prospectively collected during nuMoM2b (biomarkers, uterine artery Doppler studies, fetal growth, psychosocial determinants, sleep, and blood pressure) and rigorous definitions of adverse pregnancy outcomes. These data are stored in the NICHD repository DASH (https://dash.nichd.nih.gov/study/226675). A total of 8,838 nuMoM2b participants were targeted for contact during nuMoM2b-HHS and 7,872 participants were reached, of whom 7,003 completed one or more interval contacts. Of these, 5,206 agreed to the visit, and 4,508 attended an in-person visit.]]>
Women enrolled in the nuMoM2b study during their first pregnancies were eligible to participate in nuMoM2b Heart Health Study.]]>
2009-2014: NICHD established the Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-be Study (nuMoM2b) to study pregnant women who had not had a previous pregnancy lasting 20 weeks or more (nulliparas). Across the sites and subsites, 10,038 nulliparous women were enrolled in the study between September 30, 2010, and September 23, 2013, and followed prospectively from early during the pregnancy through delivery. 2014-2020: Subsequent to nuMoM2b, NHLBI funded an initial follow-up phase of the cohort, entitled Pregnancy as a Window to Future Cardiovascular Health: Adverse Pregnancy Outcomes as Predictors of Increased Risk Factors for Cardiovascular Disease (abbreviated as nuMoM2b Heart Health Study or nuMoM2b-HHS1). The nuMoM2b-HHS1 provided the opportunity to follow the large, diverse, and robustly characterized nuMoM2b cohort of women from early pregnancy through several years postpartum to determine how adverse pregnancy outcomes impact the risk of future cardiovascular disease in women. ]]>
