Do children benefit from taking oral zinc during acute diarrhoea? Evidence Update, Child Health Series, December 2012.
Each Evidence Update is a 2-page summary of a Cochrane Review of healthcare interventions relevant to people in low-income and middle-income countries. This Evidence Update is adapted from Lazzerini M, Ronfani L. Oral zinc for treating diarrhoea in children. Cochrane Database of Systematic Reviews 2012, Issue 6. Art. No.: CD005436. DOI: 10.1002/14651858.CD005436.pub3.
What does the research say?
The effects of zinc in acute diarrhoea:
- In children aged over 6 months, zinc may shorten the duration of diarrhoea by about half a day.
- In children with signs of moderate malnutrition, zinc shortens the duration of diarrhoea by around a whole day.
- In children aged under 6 months, zinc may have no benefit on the duration of diarrhoea.
- Zinc increases vomiting in all age groups.
- There is currently not enough evidence to be able to say whether zinc reduces death or hospitalization.
