Clinical Trial Summary

This is a single-blind randomized controlled trial, aiming to evaluate the preventive effects of mobile-based combining with hospital-based lifestyle interventions on GDM among women with advanced maternal age. It will be conducted in Beijing, with a sample size of 346. All eligible pregnant women will be randomly assigned to either the intervention or control group, and followed up to delivery.

Description:

After the adjustment of fertility policy in China, the prevalence of advanced maternal age (AMA) has become a crucial issue in maternal health care. AMA can greatly increase the risk of gestational diabetes mellitus (GDM) during pregnancy. However, there is still a lack of high-quality evidence on GDM preventive interventions for AMA pregnancy in China.

In this randomized study, the investigators aim to examine whether mobile-based combining with hospital-based lifestyle interventions have preventive effects on GDM in AMA pregnancies. The investigators will enroll a total of 346 singleton pregnant women in Peking University First Hospital and randomly assign them to either the intervention or control group. Information of maternal characteristics will be obtained at recruitment. At each prenatal visit, weight and blood pressure of all participants will be measured. For each participant, fasting venous blood samples will be collected at <14 weeks of gestation, 24-28 weeks of gestation and pre-labor, and respectively assayed for fasting plasma glucose, glycated hemoglobin. The primary outcome is the incidence of GDM. The secondary outcomes include maternal glycated hemoglobin level, maternal fasting plasma glucose level, maternal complications, pregnancy outcomes, etc.
