Description

Background: Women with gestational diabetes mellitus (GDM) are more likely to develop cardiometabolic risk (CMR). CMR refers to the risk factors that promote the chance of developing type 2 diabetes mellitus or cardiovascular events. However, using a family-centered approach, the effectiveness of continuous administration of both mobile health management and theoretical based lifestyle intervention from pregnancy to postpartum in preventing women at high risk of GDM from developing CMR has rarely been studied.

Methods: This randomized controlled trial will recruit 120 GDM pregnant women in northern Taiwan. The participants will be randomly assigned to the control group (blood glucose meters (BGM); n=40 people), intervention group 1 (continuous glucose monitoring (CGM); n=40 people), intervention group 2 (HBM-based lifestyle and mHealth intervention + CGM; n=40 people).The comparison group will receive the routine care and finger-prick test for blood glucose monitoring (BGM) during pregnancy.The intervention group 1 will receive CGM during pregnancy. The intervention group 2 will receive a HBM-based lifestyle and mHealth management program on 24-32 weeks of pregnancy, 33 weeks of pregnancy to before delivery, 4-12 weeks postpartum, including CGM during pregnancy.We intend to compare outcome variables among three groups. The outcomes variables will be assessed at baseline (24-32 weeks of pregnancy), 33 weeks of pregnancy to before delivery, 4 to 12 weeks after delivery. The primary outcomes were maternal glycemic parameters, cardiometabolic risk factors, and maternal health behavior. Outcomes will be assessed at baseline (24-32 weeks of pregnancy), 33 weeks of pregnancy to before delivery, 4 to 12 weeks after delivery. Generalized estimating equation (GEE) will be used to examine the trajectories and the effectiveness of the project for managing cardiometabolic risk on cardiometabolic risk and health behavior.
