Abstract

Vitamin A intake from food sources, not including breast milk, was determined from seven consecutive 24-h recalls for 55 children (mean age 20.8 mo, SD 8.9) from two poor communities of Guatemala City. Not including vitamin A derived from fortified sugar or breast milk, the median daily vitamin A intake was 194 retinol equivalents (RE). Including vitamin A derived from fortified sugar but not including that derived from breast milk, the median total vitamin A intake (25th and 75th percentiles) was 338 RE (146 and 617 RE) of which 78% was preformed retinol and 22% provitamin A. More than 90% of total vitamin A intake from non-breast milk food sources was derived from only 10 items; over half came from three fortified foods: fortified sugar, Incaparina and margarine. Sugar samples from 91 households in 1991 had a median of 3.3 RE/g (range, 0.0-29.9 RE/g), <25% of the target level (13-17 RE/g); nevertheless, fortified sugar provided 25% of these children's total vitamin A intake (81 RE/d) from non-breast milk food sources and their intake approached the level recommended by the FAO/WHO (400 RE/d). These results show that fortified foods make an important contribution towards vitamin A intake in this sample of poor urban Guatemalan toddlers.

摘要

通过对危地马拉城两个贫困社区的55名儿童(平均年龄20.8个月,标准差8.9)连续进行7次24小时饮食回顾调查,确定了其从食物来源(不包括母乳)中摄入的维生素A量。不包括强化糖或母乳中所含的维生素A,每日维生素A摄入量的中位数为194视黄醇当量(RE)。包括强化糖中所含的维生素A但不包括母乳中所含的维生素A,维生素A总摄入量的中位数(第25和第75百分位数)为338 RE(146和617 RE),其中78%为预形成视黄醇,22%为维生素A原。非母乳食物来源的维生素A总摄入量中,超过90%仅来自10种食物;一半以上来自三种强化食品:强化糖、Incaparina(一种混合谷物粉)和人造黄油。1991年从91户家庭采集的糖样本中,维生素A含量中位数为3.3 RE/克(范围为0.0 - 29.9 RE/克),低于目标水平(13 - 17 RE/克)的25%;尽管如此,强化糖提供了这些儿童非母乳食物来源维生素A总摄入量(81 RE/天)的25%,他们的摄入量接近粮农组织/世卫组织建议的水平(400 RE/天)。这些结果表明,强化食品对危地马拉城市贫困幼儿样本中的维生素A摄入量做出了重要贡献。
