To examine the probability of inadequacy of schoolchild nutrient intakes; to compare the predicted adequacy of schoolchild diets to previously published data for toddler diets and to examine the relative adequacy of the diets of sibling pairs.
Food consumption data were measured 2 days per month across approximately one year. Mean nutrient intakes were calculated and compared to international standards using a probability approach.
Villages in Egypt, Kenya, and Mexico.
285 school-age children (7-9 years of age) and 255 toddlers (18-30 months of age) including 94 sibling pairs.
Within a country, there was a striking similarity between the nutrients predicted to be inadequate in schoolchild and toddler diets across all nutrients except vitamin B12, which was more likely to be inadequate among schoolchildren. Nutrients of concern for both ages in one or more countries included iron, zinc, calcium, riboflavin, and vitamins B12, D, E, and A. For 94 toddler-schoolchild pairs, siblings at high risk of nutrient inadequacy could be identified from an indicator child with a sensitivity of 43-100% and a specificity of 59-100%.
Nutrient adequacy tends to be a household characteristic for these two ages of children. Nutritional interventions that target the household have a high probability of benefitting multiple age groups of children.
研究学童营养摄入不足的可能性；将学童饮食的预测充足率与先前公布的幼儿饮食数据进行比较，并研究同胞对饮食的相对充足率。
在大约一年的时间里，每月测量2天的食物消费数据。计算平均营养摄入量，并使用概率方法与国际标准进行比较。
埃及、肯尼亚和墨西哥的村庄。
285名学龄儿童（7 - 9岁）和255名幼儿（18 - 30个月），包括94对同胞。
在一个国家内，除维生素B12外，学童和幼儿饮食中预计不足的营养素在所有营养素之间存在显著相似性，维生素B12在学童中更可能不足。在一个或多个国家中，两个年龄段都值得关注的营养素包括铁、锌、钙、核黄素以及维生素B12、D、E和A。对于94对幼儿 - 学童对，可以从一个指示儿童中识别出营养不足风险高的同胞，灵敏度为43 - 100%，特异性为59 - 100%。
营养充足往往是这两个年龄段儿童的家庭特征。针对家庭的营养干预措施很有可能使多个年龄段的儿童受益。
