Effect of zinc supplementation on risk of pneumonia in children

Pneumonia is common in children younger than five years of age and may even be fatal especially in infants and low socio-economic status. Several studies have evaluated the effect of zinc on preventing respiratory tract infection and a pneumonia related decrease in childhood mortality.

Study:

Lassi and colleagues from AK University Hospital examined the literature and conducted a meta-analysis to study the  efficacy of zinc supplementation for reducing risk of pneumonia in kids. The results of the study were reported in the Cochrane Database Reviews (2010).

The investigators considered randomised controlled trials (RCTs) examining the efects of  supplementation of zinc on the risk of pneumonia in children aged 2 to 59 months of age. The database included six trials (n= 7850 children)

Result of zinc supplements on lower respiratory infections:

Zinc supplementation reduced the incidence of pneumonia by 13 percent  (risk ratio 0.87;  0.81 to 0.94).

Zinc supplementaion, based on one study reduced the prevalence of pneumonia by 41% (RR 0.59; 0.35 to 0.99).

Conclusions: Zinc supplementation reduces the incidence and prevalence of pneumonia in kids. By the way, here is a previous post on similar topic.
