Ascorbic acid intake of sixty-seven patients with myelomeningocele, ages one through eight years, was evaluated in two groups, fracture and non-fracture, to compare their intake of ascorbic acid from food-plus-supplement, food-only, and supplement-only with the recommended allowances. Intake from food-plus-supplement exceeded the allowance for 90 per cent of the fracture and 83 per cent of the non-fractured patients. Intake from food-only exceeded the recommended allowance in 79 per cent of the fracture and 75 per cent of the non-fracture subjects. All supplementations exceeded 100 per cent of the recommended allowance. There was no significant difference in the ascorbic acid intakes of fracture and non-fracture patients. Since there was no apparent correlation between fractures and ascorbic acid intake, we do not recommend ascorbic acid supplementation to prevent fractures. If such high levels are suggested, the potentially harmful effects of excessive ascorbic acid in growing children must be carefully considered.
对67名年龄在1至8岁的脊髓脊膜膨出患者的抗坏血酸摄入量进行了评估,分为骨折组和非骨折组,以比较他们从食物加补充剂、仅食物、仅补充剂中摄入的抗坏血酸与推荐摄入量。食物加补充剂的摄入量超过推荐量的比例,骨折患者为90%,非骨折患者为83%。仅从食物中摄入的量超过推荐量的比例,骨折患者为79%,非骨折患者为75%。所有补充剂的摄入量都超过了推荐量的100%。骨折患者和非骨折患者的抗坏血酸摄入量没有显著差异。由于骨折与抗坏血酸摄入量之间没有明显的相关性,我们不建议补充抗坏血酸来预防骨折。如果建议摄入如此高的水平,必须仔细考虑过量抗坏血酸对成长中儿童的潜在有害影响。
