The effects of the instantaneous scanning glucose monitoring system on hypoglycemia, weight gain, and health behaviors in patients with gestational diabetes: a randomised trial

Abstract

Background: Gestational diabetes (GDM) can cause adverse effects on parturient and newborns, and effective control of blood sugar levels in the parturient is essential for good prognosis. Continuous dynamic blood glucose monitoring can effectively improve the final pregnancy outcome of patients with GDM.Methods: A total of 110 GDM patients admitted to our hospital from April 2019 to April 2020 were selected and divided into 2 groups according to the random number table method, with 55 participants in each group. In the control group, fingertip blood glucose monitoring was used, and in the ISGMS group the ISGMS was used in combination with fingertip blood glucose monitoring. The incidence of hypoglycemia, the qualified rate of weight gain at the end of pregnancy, compliance with blood glucose monitoring, and health behavior patterns were compared between the 2 groups.Results: Patients who used the ISGSM showed a lower incidence of hypoglycemia (P<0.05), a greater qualified rate of weight gain at the end of pregnancy (P<0.05), had higher blood glucose monitoring compliance (P<0.05), and demonstrated better health behaviors (P<0.05) compared to the control group after 2 weeks of intervention. Conclusion:The application of the ISGMS in patients with GDM improved the compliance of blood glucose monitoring, improved health behaviors, reasonably controlled weight gain, and avoided hypoglycemia.

Efficacy of Continuous Glucose Monitoring on Glycaemic Control in Pregnant Women with Gestational Diabetes Mellitus—A Systematic Review

“…We found eight articles about incidences of hypoglycaemia [ 6 , 7 , 9 , 11 , 12 , 13 , 14 , 15 ]. In most studies, the outcome was that CGM detects a higher number of hypoglycaemia episodes than SMBG [ 6 , 7 , 9 , 15 ].…”

“…Gestational weight gain was analysed in three publications [ 14 , 18 , 20 ]. Two of them revealed a significantly lower increase in weight gain in the CGM group [ 14 , 20 ].…”

“…Gestational weight gain was analysed in three publications [ 14 , 18 , 20 ]. Two of them revealed a significantly lower increase in weight gain in the CGM group [ 14 , 20 ]. In addition, there was less incidence of excessive weight gain in the group using continuous glucose monitoring [ 14 , 20 ].…”

“…Two of them revealed a significantly lower increase in weight gain in the CGM group [ 14 , 20 ]. In addition, there was less incidence of excessive weight gain in the group using continuous glucose monitoring [ 14 , 20 ]. Nevertheless, the third publication, by Kestila et al, did not confirm the impact of CGM on gestational weight gain [ 18 ].…”

“…A few studies revealed the role of CGM in improving health behaviour patterns [ 14 , 20 ]. Zhang et al noted its role, especially with regard to lower gestational weight gain compared to the SMBG group [ 14 ]. However, there is limited data available in other analysed studies about this maternal outcome.…”
