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 .
The impact of zinc supplementation on growth and body composition: A randomized, controlled trial among rural Zimbabwean schoolchildren
OBJECTIVES : To assess the effect of zinc supplementation on growth and body composition among schoolchildren . DESIGN : R and omized , double-blind , placebo-controlled trial . SETTING AND SUBJECTS : 313 rural Zimbabwean schoolchildren ( 144 boys and 169 girls ) , 11–17 y ) . INTERVENTIONS : Supplementation with zinc ( 30 or 50 mg ) or placebo on schooldays for 12 months . Due to drought , a food programme was in operation during the last eight months of the study .VARIABLES : Weight , height , upper arm circumference , triceps skinfold thickness , and weight-for-age , height-for-age , weight-for-height , arm muscle-area-for-age and arm fat-area-for-age Z-scores . RESULTS : Significant effects on weight gain ( 0.51 vs 0.14 kg , P=0.01 ) , weight-for-age Z ( −0.08 vs −0.14 , P=0.01 ) and arm muscle area-for-age Z-score ( 0.10 vs 0.01 , P=0.03 ) were seen over the first three months , whereas no effects were seen over the full 12 months . CONCLUSIONS : Zinc deficiency impairing lean body mass and weight gain was documented . However , the effect of zinc seen over the first three months vanished during the last nine months when the food programme was in operation . Zinc deficiency may have persisted , but another nutrient may have become growth limiting during the last nine months . SPONSORSHIP : Danish International Development Assistance
