摘要

We investigated the effect of zinc supplementation on growth and serum IGF-1 levels in 10prepubertal Japanese children with idiopathic short statures, who had serum zinc levels ofless than 80 µg/dL. Subjects were started on oral zinc supplementation at a dose of 25 mgonce daily. In three children, the doses were increased by 50 mg once daily during thestudy period of 12 mo. The serum zinc levels rose in all subjects and reached a normalrange (beyond 80 µg/dL). However, it was found that zinc supplementation did not promotegrowth. Although the mean IGF-1 standard deviations significantly increased, the majoritydid not reach the normal range. There were no significant adverse events other than mildgastrointestinal symptoms in 4 out of 10 subjects during the supplementation period. Themost likely reason why growth was not promoted is that the zinc supplementation dosage wasnot enough to stimulate IGF-1 generation and subsequent growth velocity.
