Gestational diabetes & diabetes in pregnancy
N-terminal pro-B-type natriuretic peptide levels vary by ethnicity and are associated with insulin sensitivity after gestational diabetes mellitus
Authors' conclusion
NT-proBNP levels are lower in South Asian than in Nordic women after GDM. Lower NT-proBNP levels correlate with impaired insulin sensitivity. Lower NT-proBNP levels in South Asian women could, therefore, be attributed to impaired insulin sensitivity rather than total body fat.
Study context
- Population
- Women in Norway 1–3 years after gestational diabetes mellitus (GDM); mean (SD) age 35.3 (4.5) years, BMI 29.1 (6.0) kg/m², 164 (61%) with prediabetes/diabetes
- Participants
- 162 vs 107
- Exposure
- South Asian vs Nordic women after GDM
- South Asiann = 162
- Nordicn = 107reference
- Outcome
- Ethnic differences in circulating NT-proBNP levels
- Follow-up
- 1-3 years after GDM
