Brief 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.

Low-density Lipoprotein Levels in Participants24-32 weeks of pregnancy, 33 weeks of pregnancy to before delivery and 4-12 weeks postpartum

This outcome measure assesses the low-density lipoprotein levels in participants. The data obtained through medical record reviews. The data will be summarized by reporting the mean low-density lipoprotein level, as well as the proportion of participants classified as having high low-density lipoprotein levels based on established clinical thresholds.

Glycated Albumin Levels in Participants24-32 weeks of pregnancy, 33 weeks of pregnancy to before delivery and 4-12 weeks postpartum

This outcome measure assesses the glycated albumin levels in participants. The data obtained through medical record reviews. The data will be summarized by reporting the mean glycated albumin level, as well as the proportion of participants classified as having high glycated albumin levels based on established clinical thresholds.

Fasting Plasma Glucose Levels in Participants24-32 weeks of pregnancy, 33 weeks of pregnancy to before delivery and 4-12 weeks postpartum

This outcome measure assesses the fasting plasma glucose levels in participants. The data obtained through medical record reviews. The data will be summarized by reporting the mean fasting plasma glucose level, as well as the proportion of participants classified as having high fasting plasma glucose levels based on established clinical thresholds.

Incidence of Fetal Macrosomia as Measured by Birth Weight4-12 weeks postpartum

This outcome measure assesses the incidence of fetal macrosomia in participants. Data will be summarized by reporting the proportion of newborns classified as having fetal macrosomia based on the established weight threshold.
