Do first-trimester ultrasonographic adipose tissue measurements predict gestational diabetes mellitus in pregnant women?
First-trimester BMI is a more useful predictor of gestational diabetes mellitus than ultrasonographic visceral or subcutaneous adipose tissue measurements.
AIM: Previous studies in pregnant women reported a strong correlation between first-trimester ultrasonographic visceral adipose tissue (VAT) measurements and gestational diabetes mellitus (GDM) during the following weeks. In this study, we aimed to evaluate the clinical utility of ultrasonographic subcutaneous and visceral adipose tissue measurements between 11th and 14th weeks of gestation to predict GDM during the 24th to 28th gestational weeks. MATERIALS AND METHODS: This prospective study included a total of 142 pregnant women. Between 11th and 14th gestational weeks, we performed blinded measurements of intraperitoneal, perirenal, and subcutaneous adipose tissue thicknesses using ultrasonography. Between 24th and 28th gestational weeks, each participant underwent one-step GDM screening, and the measurement data were assessed for prognostic significance. RESULTS: Of the 142 women included, 19 (8.8%) were diagnosed with GDM. The mean intraperitoneal and maximum subcutaneous fat thickness were 51.59 ± 22.49 and 19.79 ± 12.52 mm, respectively for the GDM group and 39.88 ± 13.73 and 13.24 ± 5.70 mm, respectively for the non-GDM group. Although we observed statistically significant differences between the GDM and non-GDM groups in terms of current body mass index (BMI), subcutaneous and intraperitoneal fat thicknesses, and waist and hip circumference values, the logistic regression model showed that only current BMI had a significant association with the increasing GDM frequency. CONCLUSION: In this study investigating the clinical utility of first-trimester ultrasonographic VAT measurements during the 24th to 28th gestational weeks for the diagnosis of GDM, BMI seems to be a more useful predictor than the other anthropometric tools. However, further large-scale studies are needed to confirm these findings.
Aydın et al. (Thu,) conducted a cohort in Gestational diabetes mellitus (n=142). First-trimester ultrasonographic adipose tissue measurements and BMI was evaluated on Diagnosis of gestational diabetes mellitus. First-trimester current BMI was a more useful predictor of gestational diabetes mellitus than ultrasonographic visceral or subcutaneous adipose tissue measurements.
