Gestational weight gain among nutritionally treated GDM patients

Area of Science:

• Obstetrics and Gynecology
• Endocrinology
• Public Health Nutrition

Background:

• Gestational diabetes mellitus (GDM) requires careful management of weight gain during pregnancy.
• The 2009 Institute of Medicine (IOM) guidelines provide recommendations for gestational weight gain (GWG).
• Evaluating pregnancy outcomes based on GWG in diet-treated GDM is crucial.

Purpose of the Study:

• To assess pregnancy outcomes in women with diet-treated GDM based on adherence to 2009 IOM GWG guidelines.
• To identify factors associated with GWG compliance in GDM pregnancies.

Main Methods:

• Retrospective cohort study of 142 women with singleton, diet-treated GDM.
• Exclusion of women with pre-existing diabetes or requiring pharmaceutical treatment.
• Comparison of pregnancy outcomes between adequate GWG and excess GWG groups.

Main Results:

• 69.7% achieved adequate GWG, while 30.3% exceeded GWG recommendations.
• Women with excess GWG had higher pre-pregnancy weight and BMI.
• No significant differences in obstetrical or perinatal outcomes, despite a trend towards higher birth weight and respiratory distress in the excess GWG group.

Conclusions:

• Elevated pre-pregnancy BMI is a predictor of exceeding IOM GWG guidelines in GDM.
• In diet-treated GDM with adequate glycemic control, GWG may not be a reliable indicator of adverse pregnancy outcomes.
