Fetal overgrowth. Diabetic versus nondiabetic

Area of Science:

• Perinatal medicine
• Maternal-fetal health
• Neonatal growth assessment

Background:

• Gestational diabetes mellitus (GDM) is a significant risk factor for delivering large for gestational age (LGA) infants.
• Accurate assessment of fetal growth is crucial for managing pregnancies complicated by GDM.
• The relative growth parameter, fetal length to abdominal circumference (FL/AC) ratio, has been proposed as an indicator of fetal growth patterns.

Purpose of the Study:

• To evaluate the utility of the fetal length to abdominal circumference (FL/AC) ratio in differentiating growth patterns between LGA infants born to diabetic and nondiabetic mothers.
• To determine if the FL/AC ratio is a reliable indicator of relative fetal growth in the context of maternal diabetes.

Main Methods:

• Retrospective evaluation of newborns identified as large for gestational age (LGA).
• Measurement of the fetal length to abdominal circumference (FL/AC) ratio using ultrasound data.
• Comparison of FL/AC ratios between infants born to diabetic and nondiabetic mothers.

Main Results:

• The FL/AC ratio, representing relative fetal growth, showed no significant difference between LGA infants born to diabetic mothers and those born to nondiabetic mothers.
• This finding held true when ultrasound measurements were obtained within one week of delivery.

Conclusions:

• The FL/AC ratio may not be a distinguishing parameter for relative fetal growth in LGA infants concerning maternal diabetes status.
• Clinical utility of the FL/AC ratio in predicting growth discordance related to GDM requires further investigation.
