An interventional study of Nutrition education in Obesity & Overweight, Gestational Diabetes Mellitus in Pregnancy and Gestational Weight Gain, sponsored by University of Alabama at Birmingham. Completed at 1 site in United States. Open to female participants. Per ClinicalTrials.gov, last updated 2026-09-18.
Sponsored by University of Alabama at Birmingham · Not applicable, Interventional, and Prevention
Women with obesity who gain more weight than recommended during pregnancy are more likely to have problems such as cesarean delivery, diabetes in pregnancy, high blood pressure, and larger babies. Standard prenatal care does not usually include nutrition counseling based on weight alone. This trial tested whether adding group nutrition classes during pregnancy helps these women gain less weight during pregnancy compared to standard prenatal care alone.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Participants received standard prenatal care at UAB, which does not include nutrition counseling based on obesity alone.
Nutrition education included 1) review of recommendations for GWG and physical activity, 2) review of a unique nutrition topic, 3) a recorded cooking demonstration, and 4) receipt of ingredients for the recorded recipe.
Behavioral: Nutrition education
The intervention arm will include nutritional education, including healthy dietary practices and recipe prep with cooking demonstrations.
