Improving outcomes in gestational diabetes: does gestational weight gain matter?

Area of Science:

• Obstetrics and Gynecology
• Endocrinology
• Public Health

Background:

• Excessive gestational weight gain is a known risk factor for gestational diabetes mellitus (GDM).
• The impact of weight control after GDM diagnosis on maternal-fetal outcomes remains under-researched.

Purpose of the Study:

• To assess the association between total, early, and late gestational weight gain and maternal-fetal outcomes in women with GDM.
• To determine if weight control after GDM diagnosis can improve pregnancy outcomes.

Main Methods:

• Retrospective observational study of 546 women with GDM delivering singleton infants.
• Analysis of gestational weight gain at three intervals: total (0-36 weeks), early (0-28 weeks), and late (28-36 weeks).

Main Results:

• Higher total gestational weight gain correlated with increased risk of Caesarean section and large-for-gestational-age infants.
• Increased weight gain after GDM diagnosis (28-36 weeks) was linked to larger infants, instrumental deliveries, higher insulin doses, and poorer postpartum glucose tolerance.
• No significant associations were found between early gestational weight gain (0-28 weeks) and pregnancy outcomes.

Conclusions:

• Controlling gestational weight gain after GDM diagnosis is vital for optimizing pregnancy outcomes and maternal glucose homeostasis.
• Interventions for weight management after GDM diagnosis (around 28 weeks) can effectively improve outcomes.
