Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Preterm Infants
Infants born prematurely will have their skin, sebum, microbiota, blood, and mother's breast milk analyzed for changes between 0, 2, and 4 weeks of life.
No interventions assigned to this group
Term Infants, Control
Term infants enrolled in the UC Davis Lactation Study (protocol # 216198) will serve as the control group for this study; they will have their skin, sebum, microbiota, and mother's breast milk analyzed for changes between 0, 2, and 4 weeks of life.
