Gestationsdiabetes (GDM) (Update 2019)

BMC Pregnancy Childbirth

et al. 2020

Background: Macrosomia is a major adverse pregnancy outcome of gestational diabetes mellitus (GDM). Although BMI, symphysis-fundal height (SFH) and abdominal circumference (AC) are associated with foetal weight, there are some limitations to their use, especially for the prediction of macrosomia. This study aimed to identify a novel predictive methodology to improve the prediction of high-risk macrosomia. Methods: Clinical information was collected from 3730 patients. The association between the ISFHAC (index of the SFH algorithm multiplied by the square of AC) and foetal weight was determined and validated. A new index, the ISFHAC, was evaluated by area under the curve (AUC) analysis. Results: A total of 1087 GDM and 657 normal singleton pregnancies were analysed. The ISFHAC was positively correlated with foetal weight in GDM pregnancies and normal pregnancies (NPs). The AUCs of the ISFHAC were 0.815 in the GDM group and 0.804 in the NP group, which were higher than those of BMI, SFH, AC and GA. The ISFHAC cutoff points were 41.7 and 37 in the GDM and NP groups, respectively. The sensitivity values for the prediction of macrosomia with high ISFHAC values were 75.9 and 81.3% in the GDM and NP groups, respectively, which were higher than those with BMI. Regarding the validation data, the sensitivity values for prediction with high ISFHAC values were 78.9% (559 GDM pregnancies) and 78.3% (1427 NPs). Conclusions: The ISFHAC can be regarded as a new predictor of and risk factor for macrosomia in GDM pregnancy and NP.

“…This parameter was served as a new index that predicted fetal weight. New index was calculated with the formula below: ISFHAC×SFH (m)×AC (m) 2 . ρ in the formula is the density of human body.…”

“…In the relatively long period of pregnancy, fetuses are in a state of rapid growth with high levels of nourishment, especially in middle and late pregnancy. Nutritional counseling and exercise intervention are suitable noninvasive therapeutic options that can be readily applied to manage weight gain and improve the pregnancy outcomes of women with GDM [2][3][4][5][6]. The incidence of fetal macrosomia and cesarean delivery is also significantly higher for GDM pregnancies [7].…”
