NCT02802566

Brief Summary

The purpose of this study is to devise and pilot a BMI-based prenatal vitamin for obese pregnant women. Currently, all pregnant women, regardless of body mass index, take the same prenatal vitamin. The investigators have found that obese pregnant women have higher levels of inflammation and oxidative stress, and a concomitant depletion of specific antioxidant micronutrients. The investigators have also found, in an animal model, that decreasing inflammation and oxidative stress during obese pregnancy was associated with improved offspring outcomes. Here the investigators aim to understand whether a BMI-based prenatal vitamin is effective in decreasing markers of inflammation and oxidative stress by raising concentrations of antioxidant micronutrients and in pregnancies complicated by obesity.
