Background Zinc deficiency is prevalent in low‐and middle‐income countries, and
contributes to significant diarrhoea‐, pneumonia‐, and malaria‐related morbidity and
mortality among young children. Zinc deficiency also impairs growth. Objectives To assess
the effects of zinc supplementation for preventing mortality and morbidity, and for promoting
growth, in children aged six months to 12 years of age.

Background Zinc deficiency is prevalent in low‐and middle‐income countries, and is
considered a significant risk factor for morbidity, mortality, and linear growth failure. The
effectiveness of preventive zinc supplementation in reducing prevalence of zinc deficiency
needs to be assessed. Objectives To assess the effects of zinc supplementation for
preventing mortality and morbidity, and for promoting growth, in children aged 6 months to
12 years.
