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

Cardiovasc DiabetolPublished Cross-sectional study

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
