Insights
Zinc supplementation significantly improved weight gain in Nigerian children with acute diarrhea. This study indicates zinc is beneficial for treating diarrhea in this age group, with no reported adverse effects.
Area of Science:
- Pediatrics
- Nutritional Science
- Public Health
Background:
- Diarrheal disease is a leading cause of mortality in Nigerian children under five.
- Acute diarrhea poses a significant health burden in developing countries.
Purpose of the Study:
- To evaluate the efficacy of zinc supplementation in managing acute diarrhea in children aged 6-24 months.
- To assess the impact of zinc on plasma zinc levels and clinical outcomes.
Main Methods:
- A multi-centered, randomized, double-blind, placebo-controlled trial was conducted.
- Participants were allocated to either a zinc-supplemented or placebo group.
- Plasma zinc levels were measured, and children were monitored for three months.
Main Results:
- While plasma zinc levels did not differ significantly between groups, the zinc-supplemented group showed greater average weight gain (1.1 kg vs. 0.73 kg).
- The observed difference in weight gain was statistically significant (p = 0.00).
- No adverse effects were associated with zinc supplementation.
Conclusions:
- Zinc supplementation demonstrates a beneficial effect in children experiencing acute diarrhea.
- The study supports the use of zinc as an effective intervention for acute diarrhea, particularly regarding nutritional recovery.
Background:
In Nigeria, diarrhoeal disease is second only to malaria as a cause of death the under 5 age group. This study was aimed at assessing the benefit or otherwise of zinc supplement in acute diarrhoea.
Subjects And Methods:
This was a multi-centred randomized double blind controlled study. Children with acute diarrhoea aged between 6 and 24 months were randomized into zinc supplemented and placebo groups. Plasma zinc levels were analyzed at enrollment and at the end of the study. The children were reviewed for the next three months from the time of enrollment.
Results:
The mean plasma zinc levels at baseline and at the end of the study were 0.06 +/- 0.04 and 0.067 +/- 0.03 ppm in the zinc supplemented group and 0.11 +/- 0.02 and 0.05 +/- 0.03 ppm in the control group. The differences were not statistically significant. The zinc supplemented group had an average weight gain of 1.1 kg as against 0.73 kg (p = 0.00) for the control group in the study period. No adverse effect was reported on account of zinc supplementation.
Conclusion:
Zinc supplementation is beneficial in acute diarrhoea as observed in this study.
