This study is a randomized controlled trial, with directly observed supplement intake. Pregnant women are randomly assigned to receive daily either UNIMMAP tablet ( vitamin A 800µg, vitamin E 10 mg, vitamin D 5 µg, vitamin B1 1.4 mg, vitamin B2 1.4 mg, niacin 18 mg, vitamin B6 1.9 mg, vitamin B12 2.6 µg, folic acid 400 µg, vitamin C 70 mg, iron 30 mg, zinc 15 mg, copper 2 mg, selenium 65 µg, and iodine 150 µg) until delivery, or either a food supplement containing the UNIMMAP. The food supplement consists of 33% peanut butter, 32% heat-treated soy flour, 15% vegetable oil, 20% plain sugar and the UNIMMAP micronutrient cocktail in powdered form. Each participant allocated to the FS study group will receive 72g of FS daily which provides 1.56 MJ (372 kcal) of energy and 14.7g protein. The supplement is produced by a local women's association in collaboration with a food technologist, the micronutrients in the FS are dosed by a laboratory technician. UNIMMAP micronutrient tablets are manufactured by Scanpharm (Copenhagen, Denmark). A randomization scheme is generated by a computer program in permuted blocks of 4. Randomization numbers are sealed in opaque envelopes by administrative staff. At each inclusion, the consulting physician in the field opens the next sealed envelope and transmits the randomization number in case of MMN to a pharmacist managing for the packaging of drugs in individual plastic zip sachets containing 31 tablets. In case the randomization number shows allocation to the FS group, the responsible of the FS production site together with project staff, prepares a plastic bag containing 31 FS sachets.
