The Hoosier Moms Cohort

Indiana University411 enrolled

Overview

The Hoosier Moms Cohort (HMC) study's goal is to better understand the pathophysiology underlying the development of gestational diabetes mellitus (GDM) in pregnant women and its transition to Type 2 diabetes mellitus in mothers and their exposed children. The HMC study wants to determine what biomarkers (genetic, blood based and behavioral/interventional) can be identified in pregnant women affected with GDM and how those biomarkers can be used to impact preventative care.

Predictive GDM genetic risk models will be tested and refined in the Hoosier Moms Cohort. In addition to prospectively using genetic information to predict GDM risk, the Hoosier Moms Cohort will incorporate the use of wearable/digital devices for collection of detailed behavioral information, support development of novel dietary capture methods, and enable the collection of specimens specifically aimed at multiple 'omics' techniques to engage in a detailed, multidimensional assessment of pathophysiologic pathways and biomarkers.
