Summary

This study aims to examine the effects of a lifestyle intervention based on a health belief model (HBM) supported by mobile health (mHealth) and the impact of continuous glucose monitoring (CGM) on maternal glycemic parameters, cardiometabolic risk, health behavior and infant's outcomes among women diagnosed with gestational diabetes mellitus (GDM).

Detailed 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.

Conditions

• Gestational Diabetes Mellitus
• Continuous Glucose Monitoring

Interventions

Type	Name	Description
DEVICE	Continuous glucose monitor	Participants will receive a set of continuous glucose monitor (CGM) at 24-32 weeks of pregnancy (first set); and 33 weeks of pregnancy to before delivery (second set) respectively. CGM wearing instruction will be provided before the first wearing at 24-32 weeks of pregnancy. After completing the first wearing (approximately 7-14 days after starting to wear), the investigators will provide glucose monitor reports. The second CGM was worn from the 33rd week of pregnancy to before delivery, and another glucose monitor reports was given approximately 7-14 days after starting to wear.
BEHAVIORAL	Perinatal nursing care for gestational diabetes	Individual nursing care and consultation for women with gestational diabetes mellitus, including glucose monitor suggestions, dietary suggestions, emotional support, breastfeeding support at 24-32 weeks of pregnancy, 33 weeks of pregnancy to before delivery, and 4-12 weeks postpartum.
OTHER	Blood glucose meters (BGM)	Participants are required to use blood glucose meters (BGM) at 24-32 weeks of pregnancy and 33 weeks to before delivery. After 7-14 days of glucose monitoring at 24-32 weeks of pregnancy, glucose monitor reports will be given to the participants. After the 7-14 days of glucose monitoring at 33 weeks to before delivery, another glucose monitor reports will be given to the participants.
