Mothers and Infants LinKed for Healthy Growth

Congratulations Mom and Welcome Baby!

This study is being conducted by Dr. Ellen Demerath Ph.D. Division of Epidemiology and Community Health at the University of Minnesota, Patricia Fontaine, M.D. Senior Clinical Investigator at Health Partners Institute for Education and Research, and David Fields, Ph.D. at University of Oklahoma-Health Sciences. It is funded by the National Institute for Child Health and Development (NICHD).

Study Purpose

The purpose of this study is to learn more about how breast milk is related to mother and infant weight gain and body composition (the amount of muscle and fat that is in your body). About 360 mothers/infants pairs will take part in this study from Minnesota and Oklahoma, with about 225 participants from Minnesota and 135 from Oklahoma.
