Department of Human Nutrition researchers studied the dietary zinc intake of 1927 New Zealand school children at the age from 5 to 15 and found out that children of Pacific ethnic origin are of greater exposure to zinc deficiency. The study is published in the British Journal of Nutrition.

Rosalind Gibson who led the Ministry of Health-funded study reported that 21% of Pacific rooted research participants were exposed to a low zinc level compared to only 16% of European rooted children. The greatest risk of zinc deficiency must be faced by younger boys especially of Pacific origin.

Gibson points out: "The prevalence of low serum zinc levels among Pacific children is concerning because it exceeds the threshold at which the World Health Organization recommends public health interventions to improve zinc status."

The substance of zinc is an essential component for a children’s optimal physical development. Children who face deficiency face disturbance of growth. Nutritional sources of zinc are for instance organ meats such as liver and kidney, fish, egg yolk or cheese.

A deficiency might be avoided if children consistently consume zinc containing food. "Most children would not require supplements, but parents who are concerned that their child may be small for their age and have a poor appetite should consult with their healthcare professional to see whether zinc deficiency might be an issue."
