| Measure | Time frame |
|---|---|
| Main Objective: The aim of this study is to determine if metformin, administered to obese women during pregnancy, reduces the future life risk of obesity and metabolic syndrome in their babies. ;Secondary Objective: We will use metformin administration as a tool to explore the mechanism by which obesity causes adverse pregnancy outcomes, with a particular focus on insulin resistance (IR). ; Primary end point(s): 1. What is the efficacy of metformin (up to 2500mg daily), given to obese pregnant women from 12 - 16 weeks gestation until delivery in reducing birthweight centile of the baby? 2. What is the pattern of association between insulin resistance and adverse pregnancy outcome in obese pregnant women? | — |
