    Pregnancy as a Window to Future Cardiovascular Health: Design and Implementation of the nuMoM2b Heart Health Study
    (Oxford University Press, 2016-03-15) Haas, David M.; Ehrenthal, Deborah B.; Koch, Matthew A.; Catov, Janet M.; Barnes, Shannon E.; Facco, Francesca; Parker, Corette B.; Mercer, Brian M.; Bairey-Merz, C. Noel; Silver, Robert M.; Wapner, Ronald J.; Simhan, Hyagriv N.; Hoffman, Matthew K.; Grobman, William A.; Greenland, Philip; Wing, Deborah A.; Saade, George R.; Parry, Samuel; Zee, Phyllis C.; Reddy, Uma M.; Pemberton, Victoria L.; Burwen, Dale R.; Department of Obstetrics and Gynecology, IU School of Medicine
    The National Institute of Child Health and Human Development's Nulliparous Pregnancy Outcomes Study-Monitoring Mothers-to-Be (nuMoM2b) Heart Health Study (HHS) was designed to investigate the relationships between adverse pregnancy outcomes and modifiable risk factors for cardiovascular disease. The ongoing nuMoM2b-HHS, which started in 2013, is a prospective follow-up of the nuMoM2b cohort, which included 10,038 women recruited between 2010 and 2013 from 8 centers across the United States who were initially observed over the course of their first pregnancies. In this report, we detail the design and study procedures of the nuMoM2b-HHS. Women in the pregnancy cohort who consented to be contacted for participation in future studies were approached at 6-month intervals to ascertain health information and to maintain ongoing contact. Two to 5 years after completion of the pregnancy documented in the nuMoM2b, women in the nuMoM2b-HHS were invited to an in-person study visit. During this visit, they completed psychosocial and medical history questionnaires and had clinical measurements and biological specimens obtained. A subcohort of participants who had objective assessments of sleep-disordered breathing during pregnancy were asked to repeat this investigation. This unique prospective observational study includes a large, geographically and ethnically diverse cohort, rich depth of phenotypic information about adverse pregnancy outcomes, and clinical data and biospecimens from early in the index pregnancy onward. Data obtained from this cohort will provide mechanistic and clinical insights into how data on a first pregnancy can provide information about the potential development of subsequent risk factors for cardiovascular disease.

    Searching and visualizing genetic associations of pregnancy traits by using GnuMoM2b
    (Oxford University Press, 2023) Yan, Qi; Guerrero, Rafael F.; Khan, Raiyan R.; Surujnarine, Andy A.; Wapner, Ronald J.; Hahn, Matthew W.; Raja, Anita; Salleb-Aouissi, Ansaf; Grobman, William A.; Simhan, Hyagriv; Blue, Nathan R.; Silver, Robert; Chung, Judith H.; Reddy, Uma M.; Radivojac, Predrag; Pe’er, Itsik; Haas, David M.; Obstetrics and Gynecology, School of Medicine
    Adverse pregnancy outcomes (APOs) are major risk factors for women's health during pregnancy and even in the years after pregnancy. Due to the heterogeneity of APOs, only few genetic associations have been identified. In this report, we conducted genome-wide association studies (GWASs) of 479 traits that are possibly related to APOs using a large and racially diverse study, Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-Be (nuMoM2b). To display extensive results, we developed a web-based tool GnuMoM2b (https://gnumom2b.cumcobgyn.org/) for searching, visualizing, and sharing results from a GWAS of 479 pregnancy traits as well as phenome-wide association studies of more than 17 million single nucleotide polymorphisms. The genetic results from 3 ancestries (Europeans, Africans, and Admixed Americans) and meta-analyses are populated in GnuMoM2b. In conclusion, GnuMoM2b is a valuable resource for extraction of pregnancy-related genetic results and shows the potential to facilitate meaningful discoveries.
