Effect of mobile health based peripartum management of gestational diabetes mellitus on postpartum diabetes: A randomized controlled trial.

AIMS

To investigate the effects of mobile health based peripartum management of gestational diabetes mellitus (GDM) on postpartum diabetes and factors associated with postpartum diabetes.

METHODS

Women with GDM (n = 309) were randomly assigned to receive standard management (SM) or mobile management (MM). 75-g OGTT was performed at 6 weeks postpartum.

RESULTS

The incidence of postpartum T2DM in the MM group was much higher than that in SM group (12.36% vs. 3.88%, P =  0.0291). The fasting, 1-h and 2 h OGTT at 24-28 weeks of gestation of T2DM women were higher than those women without T2DM (fasting, 6.08 vs. 4.90, P = 0.0052; 1-h, 13.20 vs. 10.00, P < 0.0001; 11.96 vs. 8.83, P = 0.0026) in MM group. The 1-h and 2 h OGTT at 24-28 weeks of gestation of T2DM women were higher than those women without T2DM (11.54 vs. 9.78, P = 0.0484; 10.68 vs. 8.68, P = 0.0108) in SM group. Higher OGTT values at 24-28 weeks of gestation were risk factors of postpartum T2DM.

CONCLUSIONS

Higher OGTT values at 24-28 weeks of gestation were risk factors to develop postpartum T2DM. Mobile health based peripartum management of GDM increased the risk of postpartum diabetes among women with GDM for lacking of postpartum management. Further studies of mobile health based postpartum management of GDM are needed. ClinicalTrials.gov registration number NCT03748576.
