Brief summary: The study evaluates the efficacy of providing weekly iron-folate (IFA) supplements or Multiple Micronutrient (MM) supplements before pregnancy in increasing birth weight and duration of gestation as well as maternal and infant iron status.

Detailed description: Low birth weight and anemia remain intractable problems in many developing countries despite considerable efforts to address them. Intervening with just prenatal iron-folate (IFA) supplements may not be the best approach given the substantial demands for iron by maternal and fetal tissues. Therefore, there is an urgent need to evaluate the additional contribution of prepregnancy interventions.

The study evaluates the efficacy of providing weekly iron-folate (IFA) supplements or Multiple Micronutrient (MM) supplements before pregnancy in increasing birth weight and duration of gestation as well as maternal and infant iron status.
