Supplementing newborn infants with vitamin A reduces mortality at age 6 months
- Bloem, Martin W MD, PhD
BACKGROUND
Vitamin A supplementation significantly reduces mortality, particularly in children aged 6 months or older. However the effect of supplementation at birth on mortality at age 6 months is not known.
OBJECTIVE
To examine the effects of supplementing newborn infants with vitamin A on mortality at 6 months.
SETTING
Two rural districts of Tamil Nadu, southern India; June 1998 to March 2001.
METHOD
Randomised controlled trial.
PARTICIPANTS
11, 619 newborn infants. All liveborn infants within participating villages were eligible for inclusion. Pregnant women were recruited prior to delivery and were randomised at recruitment. Post-randomisation exclusions included: stillbirths, miscarriages, delivery >20 km outside of the study area and infants who died before arrival of the study team.
INTERVENTION
Vitamin A (two oral doses of 24,000 IU with a 24h interval) or placebo within 48 h after birth. In order to ensure consumption of the complete dose, mothers were encouraged to breast feed the infant immediately after treatment.
OUTCOMES
Mortality within the first 6 months of life.
MAIN RESULTS
Vitamin A supplementation significantly reduced mortality within the first 6 months of life compared with placebo (reduction in total mortality, vitamin A versus placebo 22%, 95% CI 4 to 37%; RR of mortality 0.78, 95% CI 0.63 to 0.97).
AUTHORS' CONCLUSIONS
Vitamin A supplementation within 48 h of birth significantly reduced early infant mortality.
