Raw data about GDM

In order to investigate the dietary pattern of gestational diabetes mellitus (GDM) patients, and assess the relationship between pre-gestational body mass index (BMI), gestational and postpartum glucose tolerance situation in GDM patients. 156 patients diagnosed with GDM from 2016 to 2017 were included in this study. Participants’ dietary energy intake and sources were ascertained and medical nutrition therapy (MNT) was given to them. The oral glucose tolerance test (OGTT) done during gestation and 42 days postpartum was named OGTT1 and ppOGTT, respectively. GDM patients were divided into 6 groups according to their OGTT1-FPG (fasting plasma glucose), OGTT1-1hPG (postprandial glucose) and OGTT1-2hPG results. We found that 73.7% of GDM patients’ energy intake was insufficient, with an insufficient proportion of carbohydrates and protein and an overly sufficient amount of fat. GDM patients who were overweight before pregnancy had a greater risk for higher OGTT1-FPG by a factor of 4.583 compared to patients who had a normal weight (P=0.021, OR=4.583). In addition, an abnormal OGTT1-2h PG was a risk factor for an abnormal ppOGTT (P=0.04). The 156 patients’ original information and statistic methods applied is shown below.
