Abstract: Objective To analyze the influence of group pregnancy health care service mode on blood sugar level, delivery outcome and psychological state of gestational diabetes mellitus patients. Methods A total of 150 pregnant women with gestational diabetes mellitus who filed in The Eighth People's Hospital of Dongguan from January 2021 to January 2022 and planned to give birth were selected as the research object, and were randomly divided into two groups, with 75 patients in each group. The control group received routine pregnancy care service, and the observation group added the intervention of group pregnancy care service mode. Blood glucose levels, anxiety and depression scores before and after intervention were compared between the two groups, and delivery outcomes were compared between the two groups. Results Before intervention, fasting blood glucose, 2h postprandial blood glucose and glycated hemoglobin indexes were not different between the two groups (P>0.05). After intervention, the fasting blood glucose, postprandial 2h blood glucose and glycated haemoglobin indices of the observation group were lower(P<0.05). The natural delivery rate in the observation group was higher(P<0.05). There were no differences in fetal distress, macrosomia, postpartum hemorrhage and hypertension during pregnancy between the two groups (P>0.05). Before intervention, there was no difference in SAS and SDS scores between the two groups (P>0.05). After intervention, the SAS and SDS scores of the observation group were lower(P<0.05). Conclusion The group pregnancy care service model can help to regulate the blood sugar level of gestational diabetes mellitus patients, improve the natural delivery rate, reduce the adverse pregnancy outcome, and help to improve the psychological state of patients, which is of great significance for popularization and use.
