The goal of this randomised controlled trial is to test the effectiveness of a mobile instant messaging-based lifestyle intervention in pregnant women at risk of gestational diabetes
Gestational diabetes mellitus (GDM) is one of the most common medical conditions during pregnancy, affecting about 1 in 7 live births worldwide. There remains a lack of proven preventive strategies for GDM that could be readily adopted in clinical practice. Recent studies have suggested that lifestyle intervention delivered via mobile phone could help pregnant women prevent GDM, but more evidence is needed. This study aims to test a mobile instant messaging-based lifestyle intervention for GDM prevention in pregnant women at risk of GDM.
842 studies on the registry are indexed under Diabetes, Gestational; 198 are open to participants now.
This study's planned enrollment of 944 is above the median of 110 across 550 interventional studies indexed under Diabetes, Gestational.
