Micronutrients and Adverse Pregnancy Outcomes in the Context of HIV Infection

HIV infection is a global public health problem, particularly in Africa. Concurrently, micronutrient deficiencies and adverse pregnancy outcomes are prevalent in the same settings. Supplements containing B complex and vitamins C and E were efficacious in reducing adverse pregnancy outcomes, including fetal loss, low birth weight, and prematurity among HIV-infected women; the generalizability of this finding to uninfected women is being examined. There is little encouragement from published studies to provide prenatal vitamin A supplements in HIV infection, particularly in light of significantly higher risk of mother-to-child transmission observed in one trial. The efficacy and safety of prenatal zinc and selenium supplements on these outcomes need to be examined in randomized trials .
