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

ABSTRACT

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.
