초록

본 연구는 임신초기 초음파에 의해 측정된 임산부의 복부 피하지방두께(Abdominal Subcutaneous Fat Thickness; ASFT)와 임신중기 발현되는 임신성당뇨(Gestational Diabetes Mellitus; GDM)와의 연관성을 확인하고 GDM 예측을 위한 ASFT의 기준을 알아보고자 하였다. 286명의 임산부를 대상으로 임신초기 ASFT를 측정한 후 임신중기 GDM 선별검사(50 g OGTT) 140 mg/dL 이상을 고위험군으로 산정하고 산모연령, 임신 전 체질량지수, 임신 중 체중증가량과 함께 비교 분석하였다. ROC 곡선분석을 이용하여 GDM 예측을 위한 ASFT의 cut-off value를 결정하였다. 산모연령, 임신 중 체중증가량은 임신중기 GDM과 관련성이 없었으며, 임신 전 체질량지수와 임신초기 ASFT는 정상군과 GDM 고위험군에서 의미있는 차이를 보였다. GDM 예측을 위한 ASFT의 cut-off value는 2.23 cm(AUC 0.913, Sensitivity 76.19%, Specificity 93.72%)로 결정하였다. 임신초기 초음파로 측정된 ASFT는 임신중기 GDM 예측을 위한 중요한 지표로 유용하게 평가되었다. 따라서 ASFT는 GDM을 조기에 인식하는데 있어서 보조적인 진단지표로 활용할 수 있을 것으로 사료된다.

The purpose of this study was to investigate the relationship between abdominal subcutaneous fat thickness(ASFT) and maternal gestational diabetes mellitus(GDM) measured by ultrasound at period of pregnancy. We compared maternal age, pre-pregnancy body mass index, and weight gain during pregnancy in 286 pregnant women who were diagnosed with early pregnancy ASFT and high GDM screening test(50 g OGTT) of more than 140 mg/dL. ROC curve analysis was used to determine the cut-off value of ASFT for GDM prediction. Maternal age and weight gain during pregnancy were not related to GDM in the mid-trimester and pre-pregnancy body mass index and earely pregnancy ASFT were significantly different between normal and GDM high risk groups. The cut-off value of ASFT for GDM prediction was 2.23 cm(AUC 0.913. Sensitivity 76.19%, Specificity 93.72%). ASFT measured by ultrasound in early pregnancy was useful as an important index for predicting mid-trimester GDM prediction. Therefore, ASFT can be used as an auxiliary diagnostic index for early recognition of GDM.
