Insights
High-dose vitamin A supplementation significantly reduced child mortality by 26% in communities with high malnutrition. This intervention was cost-effective and easily integrated into existing health programs, improving child survival rates.
Area of Science:
- Public Health
- Nutritional Epidemiology
- International Health
Background:
- High child mortality and malnutrition are prevalent in many low-income regions.
- Vitamin A deficiency is a significant contributor to childhood illness and death.
- Effective, scalable interventions are needed to improve child survival.
Purpose of the Study:
- To evaluate the impact of a single high dose of vitamin A on child mortality in high-risk communities.
- To assess the feasibility of integrating community-wide vitamin A supplementation into primary healthcare programs.
Main Methods:
- An opportunistic controlled trial was conducted in Jumla district, Nepal.
- 3786 children under 5 received a single high dose of vitamin A, while 3411 children in control subdistricts did not.
- Mortality and causes of death were monitored for five months post-supplementation.
Main Results:
- Supplemented children aged 1-59 months had a 26% lower risk of death (RR 0.74).
- Mortality reduction was most pronounced in infants aged 6-11 months (RR 0.51).
- Diarrheal disease mortality also decreased significantly (RR 0.65), with an estimated cost of $11 per death averted.
Conclusions:
- Vitamin A supplementation plays a crucial role in enhancing child survival.
- The vitamin A supplementation program was successfully integrated into existing community health services with minimal additional cost.
Objectives:
To determine whether a single high dose of vitamin A given to all children in communities with high mortality and malnutrition could affect mortality and to assess whether periodic community wide supplementation could be readily incorporated into an ongoing primary health programme.
Design:
Opportunistic controlled trial.
Setting:
Jumla district, Nepal.
Subjects:
All children aged under 5 years; 3786 in eight subdistricts given single dose of vitamin A and 3411 in remaining eight subdistricts given no supplementation.
Main Outcome Measures:
Mortality and cause of death in the five months after supplementation.
Results:
Risk of death for children aged 1-59 months in supplemented communities was 26% lower (relative risk 0.74, 95% confidence interval 0.55 to 0.99) than in unsupplemented communities. The reduction in mortality was greatest among children aged 6-11 months: death rate (deaths/1000 child years at risk) was 133.8 in supplemented children and 260.8 in unsupplemented children (relative risk 0.51, 0.30 to 0.89). The death rate from diarrhoea was also reduced (63.5 supplemented v 97.5 unsupplemented; relative risk 0.65, 0.44 to 0.95). The extra cost per death averted was about $11.
Conclusion:
The results support a role for Vitamin A in increasing child survival. The supplementation programme was readily integrated with the ongoing community health programme at little extra cost.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
