To estimate the nutritional risk in children 2 to 6 y old.
The sample consisted of 3058 children enrolled in public and private schools in nine Brazilian cities. The assessment of nutrient intake was based on 1-d data combining direct individual weighing of foods and a food diary. A second evaluation of food consumption was conducted in a subsample to estimate the usual intake.
There was low prevalence of inadequate intake of vitamin B6 (<0.001%), riboflavin (<0.001%), niacin (<0.001%), thiamin (<0.001%), folate (<0.001%), phosphorus (<0.1%), magnesium (<0.1%), iron (<0.5%), copper (<0.001%), zinc (<0.5%), and selenium (<0.001%). However, 22% of children younger than 4 y and 5% of children older than 4 y consumed fiber quantities larger than the adequate intake. Approximately 30% of the sample consumed more saturated fat than recommended. The prevalence of inadequate vitamin E intake ranged from 15% to 29%. More than 90% of the children had an inadequate vitamin D intake. In children older than 4 y, the prevalence of inadequate calcium intake was approximately 45%. Sodium intake was higher than the upper intake level in 90% of children younger than 4 y and 73% of children older than 4 y.
The prevalence of inadequate dietary intake was low for most nutrients. However, fiber, calcium, and vitamin D and E intakes were lower than recommended. Moreover, children consumed large amounts of sodium and saturated fat.
评估 2 至 6 岁儿童的营养风险。
该样本由来自巴西 9 个城市的公立和私立学校的 3058 名儿童组成。营养素摄入量的评估基于 1 天的数据,该数据结合了食物的直接个体称重和食物日记。在子样本中进行了对食物消耗的二次评估,以估计通常的摄入量。
维生素 B6(<0.001%)、核黄素(<0.001%)、烟酸(<0.001%)、硫胺素(<0.001%)、叶酸(<0.001%)、磷(<0.1%)、镁(<0.1%)、铁(<0.5%)、铜(<0.001%)、锌(<0.5%)和硒(<0.001%)的摄入不足率较低。然而,22%的 4 岁以下儿童和 5%的 4 岁以上儿童摄入的纤维量超过了适宜摄入量。大约 30%的样本摄入的饱和脂肪超过了建议量。维生素 E 摄入不足的患病率在 15%至 29%之间。超过 90%的儿童维生素 D 摄入不足。4 岁以上儿童钙摄入不足的患病率约为 45%。90%的 4 岁以下儿童和 73%的 4 岁以上儿童的钠摄入量高于上限。
大多数营养素的饮食摄入不足率较低。然而,纤维、钙和维生素 D 和 E 的摄入量低于建议量。此外,儿童摄入大量的钠和饱和脂肪。
