NCT04132310

Brief Summary

Early life influences (including the intrauterine environment, birth weight, and early postnatal growth) shape subsequent weight trajectories and future chronic disease risk. The MINT study will evaluate whether maternal fat mass changes are associated with specific maternal weight trajectories during pregnancy, and with neonatal adiposity at birth. The study is a prospective observational cohort currently enrolling women in early pregnancy,and following mothers and infants after birth.

Outcome Measures

Primary Outcomes (2)

  • Maternal fat mass changes during pregnancy and postpartum

    Mother's fat mass at 14 weeks, 24 weeks, and 35 weeks gestation, and up to 24-months postpartum as a continuous variable. This will be ascertained through MRI and DXA.

    14, 24, 35 weeks gestation, and up to 24-months postpartum

  • Infant percent fat at birth

    Infant percent fat at birth as a continuous variable. This will be ascertained through neonatal skinfolds and anthropometry.

    24-72 hours after birth

Secondary Outcomes (3)

  • Maternal weight trajectories during pregnancy and postpartum

    Weekly after enrollment (up to 6 weeks postpartum), biweekly 2 to 24 months postpartum

  • Maternal regional adipose tissue during pregnancy and postpartum

    14, 24,35 weeks gestation, and up to 24-months postpartum

  • Infant percent fat after birth

    1-week to 24-months

Study Arms (1)

Healthy VolunteersYes
Age GroupsAdult (18-64)
Sampling MethodNon-Probability Sample
Study Population

We plan to recruit up to 60 pregnant women around 8-14 weeks gestation and will follow the 60 babies after birth. If the pregnant mother identifies a partner for the partner component, we will seek to enroll the partner in the study, and therefore, we estimate that we will enroll up to 60 partners.

You may qualify if:
