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 .
Zinc supplementation does not affect growth, morbidity, or motor development of US term breastfed infants at 4-10 mo of age.
BACKGROUND It has been documented that growth patterns differ between breastfed and formula-fed infants . Some investigators have suggested that these differences may be related to differences in zinc nutriture . OBJECTIVE The objective of this study was to examine the effect of zinc supplementation on growth , morbidity , and motor development in healthy , term , breastfed infants . DESIGN We conducted a r and omized double-blind intervention comparing zinc supplementation ( 5 mg/d as zinc sulfate ) with placebo in breastfed infants aged 4 - 10 mo .  Growth and indexes of body composition and gross motor development were measured monthly from 3 to 10 mo . Morbidity data were collected weekly . RESULTS Eighty-five infants were enrolled , and 70 completed the study . The baseline characteristics , attained weight or length at 10 mo , growth velocity , gross motor development , and morbidity did not differ significantly between groups , even after control for potentially confounding variables . CONCLUSIONS The dietary zinc intake of these breastfed infants appeared to be adequate , given that zinc supplementation did not affect growth , development , or risk of infection ( although sample size for detection of differences in development or infection was limited ) . Previously described differences in growth between breastfed and formula-fed infants in such population s do not appear to be due to differences in zinc nutriture
