Children of mothers with PGDM (n = 43) and GDM (n = 34) were examined at 4–9 yr of age and compared with the control group (n = 108; metabolic parameters available for n = 29). Methods: The incidence of overweight and obesity, impaired glucose tolerance, and insulin resistance were analyzed based on anthropometric and biochemical measurements. Statistical analysis was performed with statistica package. Results: In children of GDM mothers, body mass index z-score (0.81 ± 1.01 vs. −0.04 ± 1.42 PGDM vs. 0.07 ± 1.28 control group) and insulin resistance indices (homeostasis model assessment index – insulin resistance 1.112 vs. 0.943 PGDM vs. 0.749 control group) were significantly higher than in other groups. Obesity and insulin resistance were also most frequent in GDM group [not significant (NS)]. In addition, the authors observed the relationship between maternal hemoglobin A1c and mean glycemia in perinatal period and insulin resistance in children. There was not such correlation for the class of maternal diabetes. Conclusion: Children born to mothers with gestational diabetes seem to be at risk for obesity and metabolic disturbances.
