Detailed description

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.
