Study information

Scientific title

Periconceptual multi-micronutrient supplementation and placental function in rural Gambian women: a randomised controlled trial

Improved maternal micronutrient status prior to conception and during early pregnancy results in improved placental growth and functional parameters, relevant to fetal growth and physiological development.

Ethics approval

Medical Research Council (MRC) and the Gambian Government Ethics Committee, 13/03/2006, reference numbers: SCC1000 and L2005.111, respectively

4. Change in maternal haematological status from baseline to 20 and 30 weeks gestation, and at delivery
5. Change in maternal micronutrient status from baseline to 20 and 30 weeks gestation, and at delivery

2. Placental volume at 30 weeks
3. Placental doppler waveforms at 30 weeks
4. Fetal anthropometry at 20, 30 weeks and at delivery
