Zinc helps with diarrhea in children: study

February 29, 2008

Treatment with zinc supplements can cut the severity and duration of acute or persistent diarrhea in children researchers note in the in the February issue of Pediatrics.
The findings stem from a pooled analysis of data from 22 relevant studies, including 16 that focused on the benefits of zinc in 15,231 children with acute diarrhea and six that looked at 2968 children with persistent diarrhea.

Zinc use cut the average duration of both acute and persistent diarrhea according to the researchers from the Medical College of Georgia in Augusta. In addition, zinc therapy reduced the average stool frequency by 18.8 percent and 12.5 percent in children with acute and persistent diarrhea, respectively.
Zinc supplements also helped prevent diarrhea. Treatment with zinc supplements reduced the occurrence of both types of diarrhea by roughly 18 percent relative to placebo.
"On the basis of these findings, which now add to the large body of previously published clinical data and update previous meta-analyses and systematic reviews, zinc therapy is useful for treating both acute and persistent diarrhea and for their prophylaxis," the researchers conclude.

Diarrhea kills more than two million people each year, the World Health Organization estimates. Most are young children living in middle- or low-income countries The study is published in the February 2008 issue of the journal Pediatrics.
