Insights
Vitamin A supplementation at birth significantly reduced infant mortality by 64% in a placebo-controlled trial. This intervention also showed a trend towards decreasing severe respiratory infections in neonates.
Area of Science:
- Neonatal Health
- Nutritional Immunology
- Public Health Interventions
Background:
- Infant mortality and morbidity remain significant global health challenges.
- Vitamin A deficiency is common in many developing regions, impacting immune function.
- Early life nutrition plays a critical role in infant survival and development.
Purpose of the Study:
- To evaluate the efficacy of single-dose oral vitamin A supplementation at birth in reducing infant mortality.
- To assess the impact of neonatal vitamin A on infant morbidity, specifically common childhood illnesses.
Main Methods:
- A randomized, placebo-controlled trial was conducted involving 2067 Indonesian neonates.
- Infants received either 52 micromol (50,000 IU) of oral vitamin A or a placebo on their first day of life.
- Infant mortality was tracked up to 1 year; morbidity was assessed in a subgroup up to 6 months.
Main Results:
- Vitamin A supplementation was associated with a 64% reduction in infant mortality (Relative Risk = 0.36; 95% CI: 0.16, 0.87).
- The protective effect on mortality was more pronounced in boys and infants with normal birth weight.
- While immediate morbidity prevalence was similar, vitamin A-treated infants showed a trend towards fewer medical treatments for cough and fever.
Conclusions:
- Single-dose neonatal vitamin A supplementation is a potentially effective strategy to decrease infant mortality rates.
- The intervention may also reduce the incidence of severe respiratory infections in early infancy.
Objective:
To determine whether vitamin A supplementation at birth could reduce infant morbidity and mortality.
Study Design:
We conducted a placebo-controlled trial among 2067 Indonesian neonates who received either 52 micromol (50,000 IU) orally administered vitamin A or placebo on the first day of life. Infants were followed up at 1 year to determine the impact of this intervention on infant mortality. A subgroup (n = 470) was also examined at 4 and 6 months of age to examine the impact on morbidity.
Results:
Vital status was confirmed in 89% of infants in both groups at 1 year. There were 19 deaths in the control group and 7 in the vitamin A group (relative risk = 0.36; 95% confidence interval = 0.16, 0.87). The impact was stronger among boys, infants of normal compared with low birth weight, and those of greater ponderal index. Among infants examined at 4 months of age, the 1-week period prevalence of common morbidities was similar for vitamin A and control infants. However, during this same 4-month period, 73% and 51% more control infants were brought for medical treatment for cough (p = 0.008) and fever (p = 0.063), respectively.
Conclusions:
Neonatal vitamin A supplementation may reduce the infant mortality rate and the prevalence of severe respiratory infection among young infants.

The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
