Summary
Brief summary
When women with gestational diabetes were randomsied to insulin or metformin treatment in the MiG study, they were asked to consent to follow up of the offpsring. We are now doing the first follow up at 2 ears including detailed body composition measurements, physcial examination and neurodevelopmental assessment. We plan to continue longterm follow up to see if metformin exposure in utero modifies later risks of obesity and type 2 diabetes
