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 .
Growth and body composition of periurban Guatemalan children in relation to zinc status: a longitudinal zinc intervention trial.
Changes in growth , body composition , and zinc indexes were evaluated after 25 wk in a double-blind zinc-supplementation study of 162 periurban Guatemalan children aged 81.5 + /- 7.0 mo ( mean + /- SD ) . Children receiving the zinc supplement ( 10 mg Zn/d as amino acid chelate ) for 90.1 + /- 9.2 d had higher mean fasting plasma zinc ( 16.2 + /- 2.9 vs 14.9 + /- 2.1 mumol/L , P < 0.01 ) , a greater increase in median triceps skinfold Z score ( 0.50 vs 0.38 , P < 0.05 ) , and a smaller deficit in median midarm circumference ( MAC ) Z score ( -0.03 vs -0.20 , P < 0.05 ) compared with the placebo group . Initial hair zinc classified as < 1.68 and > 1.68 mumol/g was the only laboratory variable that explained some of the variance in final Z scores of midarm-muscle area ( P < 0.05 ) and MAC ( P < 0.01 ) . Children responded to the zinc supplement with changes in indexes of body composition rather than growth
