Introduction: Since research investigating IGF-1 levels in breast milk are few, the goal of this study was to analyze the IGF-1 levels in the breast milk of diabetic mothers as well as in the serum of their newborn babies and to identify what relationship exists between blood serum and IGF-1 milk levels through patient measurement of mothers and their babies.

Methods: This case control study was undertaken under the auspices of the Clinic of Neonatology at Al Minia University Pediatric Hospital over May 2012 through May 2013. With a total of 30 diabetic mothers and their babies forming the experimental group and the control group consisting of 15 non-diabetic mothers and their babies. A detailed medical history, anthropometric assessments, as well as the measurement of the baby’s serum IGF-1 and their mother’s breast milk IGF-1 levels were taken from all participants using ELSIA. The resulting data were analyzed via Statistical Package for the Social Sciences (SPSS) version 16 and measurements of descriptive statistics, t-test, Chi-square test, as well as the Pearson Correlation Coefficient. 

Results: The Infants born to Diabetic Mothers (IDMs) demonstrated significantly greater anthropometric measurement. Both the serum levels and the milk IGF-1 levels as well as all of the physical measurements taken were found to have a positive correlation between the level of IGF-1 in mother’s milk and all of the anthropometric measurements studied with the exception of delivered baby’s length. 

Conclusion: Higher levels of IGF-1 are present in the milk of diabetic mothers and the blood serum of their babies and this characteristic could be used as a prenatal biomarker for macrosomia.
