Glucose Challenge Test Values Within the Normal Range and Long‐Term Risk of Type 2 Diabetes by Pre‐Pregnancy BMI : A Retrospective Cohort Study
Authors' conclusion
Pre-pregnancy BMI and GCT values within the normal range can be used for further type 2 diabetes risk stratification, ranging from minimal risk among women with a GCT < 90 mg/dL and normal weight to substantially increased risk among women with pre-pregnancy overweight or obesity.
Study context
- Population
- Pregnant women aged 20–50 with normal (< 140 mg/dL) glucose challenge test (GCT) results, 2004–2022; mean age 32.7 years1,354 developed T2D
- Participants
- 249,190 women
- Exposure
- GCT values within the normal range, combined with pre-pregnancy BMI categories
- Outcome
- T2D
- Follow-up
- Median 7 years
