Insights
Zinc supplementation was more effective than probiotics in reducing the duration and frequency of acute diarrhea in young children. Zinc also resulted in fewer complications compared to probiotics.
Area of Science:
- Pediatrics
- Gastroenterology
- Nutritional Science
Background:
- Acute diarrhea is a common childhood illness, particularly in children aged 6 months to 2 years.
- Probiotics and zinc are commonly used interventions, but their comparative efficacy requires further investigation.
Purpose of the Study:
- To compare the effectiveness of zinc supplements versus probiotics in treating acute diarrhea in young children.
- To analyze the impact of these interventions on diarrhea duration, frequency, and associated complications.
Main Methods:
- A clinical trial involving infants aged 6 months to 2 years divided into three groups: zinc supplementation, probiotic supplementation, and a control group.
- Evaluation of diarrhea frequency, duration of hospitalization, and persistence over 3-7 days.
Main Results:
- Diarrhea persisted longer in the probiotic group compared to the zinc group, with significantly higher relative risks and incidences of persistence.
- Zinc supplementation showed a significantly lower percentage of post-treatment complications (2.6%) compared to probiotics (35.5%).
Conclusions:
- Zinc supplementation (20 mg) demonstrated superior effectiveness over probiotics in managing acute diarrhea in children.
- Zinc supplementation is associated with a lower risk of complications compared to probiotic use.
Purpose:
The aim of this study was to analyze the effects of probiotics and zinc supplements on the mean duration and frequency of acute diarrhea in children aged 6 months to 2 years.
Methods:
In this clinical trial of infants aged between 6 months and 2 years, eligible patients were divided into 3 groups: Zinc Receiving Group (ZRG), Probiotic Receiving Group (PRG), and a control group receiving supportive care alone. The frequency of diarrhea was evaluated in the test groups during the first 24 hours and 48-72 hours, along with the duration of hospitalization and diarrhea persistence for 3-7 days.
Results:
Diarrhea persisted for until the third day of admission in 100% of the infants in PRG compared with only 76.1% in ZRG. The relative risk of diarrhea persistence in the PRG was 1.31 times more than in ZRG until the third day. Also, 80% of diarrhea cases in the PRG persisted until the fourth day of admission, compared with 47.8% in the ZRG group, and this value was significant. The relative incidence of diarrhea persistence in the PRG was 36.4 times greater than in the ZRG until the day 4. Also, the percentage of post-treatment complications was 35.5% in the PRG and 2.6% in the ZRG, which was significant.
Conclusion:
In our study, the effectiveness of zinc at a dose of 20 mg was higher than that of probiotics. The complications associated with zinc supplementation were lower than those of probiotics.
