Evaluating the effects of mobile health intervention on weight management, glycemic control and pregnancy outcomes in patients with gestational diabetes mellitus

PurposeTo explore the effects of mobile health (mHealth) intervention on pregnancy weight management, blood glucose control and pregnancy outcomes.MethodsA total of 124 patients with gestational diabetes mellitus (GDM) were selected. Patients were randomly divided into two groups. The 60 patients in the control group received standard outpatient treatment, while the remaining 64 patients received a nurse's online guidance both through a mobile medical App installed on their phone and through regular offline clinical treatment in the mHealth group. Patients were treated for an average of 13weeks and general conditions, compliance, blood glucose, glycosylated hemoglobin, weight gain, pregnancy, and neonatal outcomes were monitored in both groups longitudinally.ResultsThe mHealth group demonstrated higher levels of compliance (83.312.5% vs. 70.4 +/- 10.1%, t=-6.293, df=122, p<0.001), lower frequency of outpatient service (8.1 +/- 1.3 vs. 11.2 +/- 1.1, t=14.285, df=122, p<0.001), lower hemoglobin A1C before delivery (4.7 +/- 0.2 vs. 5.3 +/- 0.3, t=13.216, df=122, p<0.001) as well as the rates of off-target measurements both fasting (4.6 +/- 0.4% vs. 8.3 +/- 0.6%, t=40.659, df=122, p<0.001) and 2h post-prandial (7.9 +/- 0.7% vs. 14.7 +/- 0.8%, t=50.746, df=122, p<0.001). Weight gain in the mHealth group was less than control group (3.2 +/- 0.8 vs. 4.8 +/- 0.7, t=11.851, df=122 p<0.001).ConclusionMobile health intervention management of gestational diabetes mellitus improves patients' compliance and blood glucose control, and reduces weight gain, thereby reducing the rates of complications in both pregnant women and fetuses during delivery during pregnancy.
