Gestational diabetes & diabetes in pregnancy

Diabetes Res Clin PractPublished Population-based cohort study

Authors' conclusion

Pregnancy outcomes of 'mild' GDM were worse compared to normal glucose tolerant women however these differences were explained by the pre-pregnancy BMI difference between groups.

Hypertension during pregnancy, more prevalent in GDM: OR
1.55 (95% CI 1.05-2.28)
Induced delivery, more prevalent in GDM: OR
1.38 (95% CI 1.10-1.74)
Instrumental delivery, more prevalent in GDM: OR
1.34 (95% CI 1.07-1.68)
Acute caesarean section, more prevalent in GDM: OR
1.32 (95% CI 1.04-1.64)

Observational data: associations, not effects.
