Abstract/OtherAbstract:
BACKGROUND: Maternal postpartum vitamin A supplementation (VAS) provides an opportunity to improve vitamin A nutriture of breast fed infants in developing countries and can possibly prevent infant mortality and morbidity attributable to vitamin A deficiency.
OBJECTIVE: To evaluate the effect of maternal postpartum VAS on infant mortality, morbidity and adverse effects.
DESIGN: Systematic review, meta-analysis and meta-regression of randomized controlled trials.
DATA SOURCES: Electronic databases and abstracts and proceedings of micronutrient conferences.
REVIEW METHODS: Randomized or quasi-randomized, placebo-controlled trials evaluating the effect of postpartum, maternal synthetic VAS on mortality or morbidity within infancy (<1 year), or adverse effects.
RESULTS: The seven included trials were from developing countries. There was no evidence of a reduced risk of mortality during infancy [relative risk (RR) 1.05, 95% confidence interval (CI) 0.92-1.20, P = 0.438; I² = 0%, P = 0.940]. No variable emerged as a significant predictor of mortality but data for high-risk groups (high maternal night blindness prevalence and low birth weights) was restricted. Neonatal mortality data was available from a single study, (RR 1.09, 95% CI 0.88-1.35; P = 0.422). In two trials, there was no evidence of a reduced risk of cause-specific mortality. In one trial, there was no evidence of a decrease in either diarrhoea or acute respiratory infection. No adverse effects were reported in the single relevant trial.
CONCLUSIONS: There is no evidence of a mortality or morbidity benefit to the infant following postpartum maternal VAS. Only prevention of infant morbidity or mortality would be sufficient justification for initiating this intervention in public health programmes.
