Detailed Description:

We propose to study the efficacy of zinc or multiple micronutrient supplementation in reducing the risk of infectious diseases and growth faltering among infants and young children in Tanzania. Infants born to HIV-negative women will be recruited and randomly assigned in a factorial design to either zinc, micronutrients (vitamins C, E, B1, B2, niacin, B6, folate and B12), micronutrients plus zinc, or a placebo given daily. Children will be followed at monthly clinic visits from age 6 weeks for 18 months. Data obtained will include socioeconomic status, anthropometric data (weight, length, head circumference, and arm anthropometrics), dietary intake (including breastfeeding duration and frequency), hemoglobin, ferritin, and blood smear for malaria. The primary outcomes will be the incidence of diarrhea and respiratory tract infections. Secondary outcomes will be weight and length gain. A subset of children will be tested for blood concentrations of vitamin A, E, zinc and C-reactive protein. All children will receive a large periodic dose of vitamin A every 6 months as per standard of care in Tanzania.
