Zn supplementation was associated with increased fat-free mass among stunted children .
Due to the use of anthropometry when determining body composition , a majority of the studies could not accurately address whether alterations in the fat and /or fat-free mass components of the body were responsible for the observed changes in body composition .
The effect of Zn supplementation on body composition is not consistent but may modify fat-free mass among children with pre-existing growth failure
OBJECTIVE To provide a comprehensive synthesis of the effects of Zn supplementation on childhood body composition and adiposity-related hormone levels .
Interrelationship of indices of body composition and zinc status in 11-yr-old New Zealand children
Serum  zinc and hair zinc concentrations of some New Zeal and children aged 11 yr , were examined in relation to selected anthropometric indices . Serum zinc concentrations ( n=453 ) in boys and girls were similar and were unrelated to anthropometric indices and hair zinc concentrations . Mean hair zinc concentration ( n=620 ) of the girls was higher than that for the boys ( 2.95±0.49 vs 2.46±0.47 µmol/g ; p<0.001 ) . Correlation analysis demonstrated that , for the boys , all the studied anthropometric indices , with the exception of height , were significantly related to hair zinc concentration and that the confounding effects of mid-parent height and the timing of the adolescent growth spurt was small . Results for the girls were similar but less significant . Dichotomizing the hair zinc results divided both the boys and girls into two groups : those with hair zinc < 2.44 µmol/g were heavier ( girls , 39.0 vs 35.2 kg ; boys , 36.6 vs 34.7 kg ) and fatter ( mid-upper-arm fat area : girls , 15.2 vs 12.0 cm2 ; boys , 11.1 vs 9.5 cm2 ) compared to their counterparts with hair zinc > 2.44 µmol/g . The results demonstrate that in these healthy New Zeal and children , those with lower hair zinc concentrations are fatter and heavier than their high-hair-zinc counterparts
