Macrosomia prediction using different maternal and fetal parameters in women with 50 g glucose challenge test between 130 and 140 mg/dl.

OBJECTIVE

Our aim in this study was to investigate the association between 1-h glucose challenge test (GCT) of 130-140 mg/dl and the development of macrosomia.

METHODS

In this retrospective cohort study, patients with GCT between 130 and 140 mg/dl were divided into two groups. Macrosomic and appropriate-for-gestational-age (AGA) term neonates were compared for the presence of maternal risk factors and fetal abdominal circumference between 29 and 34 weeks.

RESULTS

There were no significant differences between the groups with respect to maternal age, parity, BMI at the first trimester and at the time of GCT, gestational weeks at delivery. However; history of a macrosomic baby delivery was significantly higher in macrosomic group (33.3% for group 1, 11.3% for group 2, p = 0.001). Abdominal circumference at 29-34 weeks of gestations was significantly higher in macrosomic group (32.46 ± 1.97 for group 1 vs. 31.06 ± 2.46 for group 2, p = 0.002).

CONCLUSION

History of a macrosomic baby delivery and abdominal measurement at 29-34 weeks was important predictors of macrosomia in patients with GCT between 130 and 140 mg/dl.
