Correlations between antepartum maternal metabolism and newborn behavior

Area of Science:

• Perinatal Medicine
• Neurodevelopmental Pediatrics
• Endocrinology

Background:

• Maternal metabolic status during pregnancy may influence fetal brain development and subsequent offspring neurobehavioral outcomes.
• Diabetes in pregnancy, both pregestational and gestational, presents a significant public health concern with potential long-term implications for child development.

Purpose of the Study:

• To investigate the relationship between maternal glycemic regulation during pregnancy and neonatal neurobehavioral assessments in offspring.
• To determine if maternal diabetes type (pregestational vs. gestational) modifies this relationship.

Main Methods:

• Serial measurements of maternal glycemic control (hemoglobin A1c, fasting plasma glucose) were collected during pregnancy.
• Offspring neurobehavioral function was assessed using the Brazelton Neonatal Behavioral Assessment Scale (BNBAS).
• Statistical analyses controlled for confounding factors such as premature birth, perinatal events, socioeconomic status, and ethnicity.

Main Results:

• Significant correlations were observed between second- and third-trimester maternal glycemic control and three of four dimensions on the BNBAS.
• Higher maternal glucose levels (hemoglobin A1c and fasting plasma glucose) were associated with poorer neonatal behavioral responses.
• These findings remained consistent across both pregestational and gestational diabetic groups and were independent of other perinatal factors.

Conclusions:

• Elevated maternal glucose levels during pregnancy are associated with measurable neurobehavioral deficits in newborns.
• Infants born to mothers with diabetes may have altered interactive capabilities from birth due to these fuel-related effects.
• These findings underscore the importance of optimal glycemic management in diabetic pregnancies to support healthy neurodevelopment.
