Summary
10 papers analyzed
These studies suggest that gestational diabetes can negatively impact the baby's mental and psychomotor development, increase risks of obesity, metabolic syndrome, and type 2 diabetes, and lead to complications such as fetal macrosomia and altered autonomic nervous system activation.

Impact of Gestational Diabetes on the Baby
Cognitive Development in Offspring
Gestational diabetes mellitus (GDM) has been linked to potential cognitive impairments in children. Studies indicate that infants born to mothers with GDM may exhibit lower scores in mental and psychomotor development during their early years. Specifically, children aged 1-2 years show significantly lower mental and psychomotor development scores compared to those born to non-diabetic mothers. Additionally, there is evidence suggesting that school-age children of mothers with GDM may have decreased intelligence quotient (IQ) scores, although the data is heterogeneous and further research is needed to confirm these findings.
Cardiovascular System Effects
The cardiovascular health of children born to mothers with GDM can also be affected. Research has shown that at one year of age, these children may exhibit signs of autonomic nervous system (ANS) activation, as indicated by lower average acceleration capacity (AAC) in electrocardiogram recordings. While no significant differences were found in anthropometric data, blood pressure, or aortic intima-media thickness between children of diabetic and non-diabetic mothers, the ANS activation could have long-term implications that require further investigation.
Metabolic and Growth Concerns
GDM is associated with an increased risk of fetal macrosomia (large body size) and babies being large for gestational age (LGA). These conditions predispose children to a higher risk of childhood obesity and type 2 diabetes later in life. The prevalence of fetal macrosomia and LGA in children born to mothers with GDM is significantly higher, with studies showing a pooled risk ratio of 1.70 for LGA and 1.45 for fetal macrosomia. This underscores the importance of early prediction and intervention to mitigate these risks.
Long-term Metabolic Risks
Children born to mothers with GDM face long-term metabolic risks, including obesity, metabolic syndrome, and type 2 diabetes. The risk of these conditions is two- to eightfold higher in offspring of mothers with GDM compared to those without. Epigenetic changes induced by maternal hyperglycemia during fetal life are believed to play a role in these increased risks. This highlights the need for ongoing monitoring and potential interventions to manage and reduce these long-term health risks.
Insulin-like Growth Factors and Fetal Development
The insulin-like growth factor (IGF) system, which plays a crucial role in fetal development, is also affected by GDM. Studies have shown that while the concentrations of IGF-1, IGF-2, and IGFBP-3 in maternal and umbilical cord blood do not significantly differ between diabetic and non-diabetic groups, there are lower levels of IGFBP-1 and IGFBP-2 in both maternal and fetal blood in the GDM group. A positive correlation between IGF-1 levels in umbilical cord blood and the length of the newborn suggests that IGF-1 may influence fetal growth.
Conclusion
Gestational diabetes mellitus has significant implications for the health and development of the baby. It can affect cognitive development, cardiovascular health, and metabolic outcomes, both in the short and long term. Early diagnosis and intervention are crucial to mitigate these risks and ensure better health outcomes for the offspring. Further research is needed to fully understand the mechanisms and to develop effective prevention and management strategies.
