This review studied the effectiveness of antenatal macronutrient nutritional interventions on maternal, neonatal, and child outcomes. Balanced energy protein (BEP) supplementation studies showed a reduced incidence of perinatal mortality, stillbirths, low birth weight (LBW) infants, small for gestational age (SGA) babies, and increased birth weight. Food distribution programs (FDPs) witnessed reduced rates of SGA, stunting, wasting, and increased birth weight and birth length. Studies on intervention for obesity prevention showed reductions in birth weight. Data from this review support the antenatal supplementation of BEP and FDP for the prevention of adverse maternal, neonatal, and child outcomes that can be utilized for future policymaking.
