Carbohydrate Intake and Oral Glucose Tolerance Test Results in the Postpartum Period
Authors' conclusion
Carbohydrate intake is not associated with post-OGTT glucose levels among postpartum individuals. Dietary preparation prior to the OGTT may not be necessary in this population.
Study context
- Population
- Postpartum individuals with recent GDM or risk factors for GDM
- Participants
- 177 vs 104
- Comparison
- Carbohydrate intake vs 120-min post-OGTT glucose
- BABIn = 177
- SPRINGn = 104
- Primary endpoint
- 120-minute post-OGTT glucose (2-hour 75-g oral glucose tolerance test (OGTT))

Further findings
Carbohydrate intake and 120-min post-OGTT glucose, adjusted for breastfeeding status
| β (mg/dL) (CI) | P value | |
|---|---|---|
| SPRING | −0.14 (−5.7 to 5.5) | P = 0.95 |
| BABI | −3.9 (−10.4 to 2.7) | P = 0.25 |
| Outcome | β (mg/dL) (CI) | P value |
|---|---|---|
| Glycemic index and 120-min post-OGTT glucose | −1.1 (−2.2 to −0.03) | P = 0.04 |
Carbohydrate intake and 120-min post-OGTT glucose, adjusted for breastfeeding status
- Adding breastfeeding status did not change results
Glycemic index and 120-min post-OGTT glucose
- Inverse relationship between glycemic index and 120-min post-OGTT glucose
