Abstract

Introduction: Supplementation is a simple and effective intervention method in public
health for control of parasite and infectious diseases in infants. The current study was
conducted to determine the effect of supplementation with zinc and vitamin A in growth rate
and morbidity of respiratory and diarrhea infections.
Methods: In a randomized clinical trial, 628 infant between 6-60 month years old assigned
to four groups; vitamin A and zinc, vitamin A, zinc and control. After collection of data
with a questionnaire, interview and weight and height measurement, they were analyzed by
regression and analysis of covariance.
Results: Supplementation with zinc and vitamin A was associated positively with infants
weight. It was also observed maximum and minimum of weight difference mean in vitamin
A and control groups, respectively. In contrast, no significant differences among four
groups in height mean, duration and incidence rate of respiratory and diarrhea infections
was observed.
Conclusion: This study showed that supplementation with zinc and vitamin A increases
infants weight. However, no effect on height increment as well as preventive effect for
diarrhea and respiratory infections was observed.
