The MOM-CARE Trial : Evaluating Antenatal and Postnatal MMSPlus for Improved Infant Birth and Growth Outcomes

This clinical trial aims to learn if MMS Plus improves infant health compared to standard MMS during pregnancy and the postnatal period in women living in peri-urban areas of Karachi, Pakistan. It will also evaluate how MMS Plus affects infant growth during the first 6 months of life. The main questions it aims to answer are: 1. Does MMS Plus during pregnancy reduce the risk of poor infant outcomes compared to standard MMS, as measured on a 5-point ordinal scale ranging from perinatal mortality to term birth with appropriate, small, or large-for-gestational-age infants? 2. Does postnatal MMS Plus improve infant length velocity at 6 months of age among exclusively breastfed infants compared to standard MMS and iron/folic acid (IFA) supplementation? Researchers will compare: 1. MMS Plus versus standard MMS during pregnancy (antenatal phase) 2. MMS Plus versus standard MMS versus IFA after birth (postnatal phase) Participants will: 1. Be randomly assigned to receive either MMS Plus or standard MMS during pregnancy 2. Be re-randomized after delivery to receive either MMS Plus, standard MMS, or IFA supplements during the postnatal period 3. Receive supplements under double-blind conditions 4. Be followed through childbirth and until the infant is 6 months of age 5. Attend regular clinic visits for health monitoring, infant assessments, and data collection. This phase III adaptive randomized controlled trial will occur in three peri-urban catchment areas of Karachi, Pakistan.
