In Utero Capacity Formation and Socio-economic Outcomes (CDS)

Harvard University
ClinicalTrials.gov Identifier:
NCT01412580
First received: August 8, 2011
Last updated: March 23, 2017
Last verified: March 2017
  Purpose
Because of the high returns of schooling in developing countries, policymakers pay a lot of attention to increasing school access. But if the mother is deficient in key micronutrients, brain development can biologically constrain children's demand for education. To execute this strategy, the investigators collect cohort observational data on a previous randomized controlled trial with micronutrient supplements offered to HIV-negative pregnant women in Dar es Salaam, Tanzania, between 2001 to 2003.
