Study of Outcomes in Mothers and Infants (SOMI)

San Diego SOMI is a research discovery platform with the goal of better understanding the complex combination of factors – from biological to social, from economic to environmental - that contribute to child health outcomes. To do this, we combine and use existing sets of data that have been collected from San Diego County communities, families, and individuals over the last 10 years and for the next 10+ years – representing a total of 1 million mother-child pairs!

Seed funding for the SOMI has been provided by the Rady Children’s Institute for Genomic Medicine.

Our Mission

The mission of SOMI is to predict and promote healthy outcomes in mothers, infants and children in collaboration with community and public health partners.

The SOMI data platform will allow multi-disciplinary researchers, policy makers, and other stakeholders to visualize and quantify disparities in child health outcomes across San Diego County and over time.

To achieve this, SOMI will utilize county-wide publicly and non-publicly available data on medical, environmental, socioeconomic, policy, and service uptake for the SOMI Million Person Mother/Child cohort.
