Metformin versus insulin for gestational diabetes: Adiposity variables and adipocytokines in offspring at age of 9 years

Diabetes Res Clin PractPublished Follow-up study of a randomised controlled trial

Authors' conclusion

Maternal metformin treatment for GDM had no effects on adiposity, body composition, liver fat, or inflammation markers in prepubertal offspring compared to maternal insulin treatment but was associated with higher adiponectin concentration and lower leptin/adiponectin-ratio in boys.

Study context

Population
Prepubertal offspring at 9 years of age of 311 mothers randomized to metformin or insulin for gestational diabetes mellitus (GDM) (follow-up rate 55%)follow-up rate 55%
Participants
172 participants
Comparison
Maternal metformin vs insulin for GDM
  • Metforminn = 82
  • Insulinn = 90reference

Primary result

As reported in the abstract

Adiposity, body composition, liver fat and inflammation markers · 9 years of age
  • Serum markers of low-grade inflammation, visceral adipose tissue volume, total fat percentage and liver fat percentage were similar between the groups

Further findings

Serum adiponectin · 9 years of age · higher with Metformin

P = 0.016

Serum adiponectin, boys · 9 years of age · difference observed in boys only
