One village will be randomly assigned to receive the locally-prepared biscuit and a daily multivitamin and the other will be randomly assigned to be an assessment-only control site. Because this is a pilot study designed to develop methodology for a future powered trial, and the logistics of local supplement preparation need to be developed in advance of the study, the randomization will occur prior to baseline testing to allow for development of infrastructure for supplement preparation. However the villagers will not be informed of the randomization until after baseline testing is complete.
