Abstract

The objective of this cross-sectional study was to investigate energy and nutrient intakes in pre-school children in Flanders-Belgium, using multistage clustered sampling. Diets of 661 children (338 boys; 323 girls) between 2.5 and 6.5 years old were assessed, with parentally reported 3 d estimated diet records. Usual energy and nutrient intakes were compared with national and international recommendations. Statistical modelling was used to account for within-individual variation. Mean daily energy intakes (boys, 6543 kJ; girls, 5757 kJ) approached the estimated energy requirements (EER) (boys, 6040 kJ; girls, 5798 kJ) for children < 4 years old. For children at least 4 years old, mean energy intakes (boys, 6408 kJ; girls, 5914 kJ) were below the EER of 6995 and 6740 kJ/d, respectively. Mean energy percentage (en%) derived from saturated fatty acids (SFA) (13-14 en%) was above the acceptable macronutrient distribution range (AMDR) upper level of 12 en%. Mean percentages derived from MUFA (10-11 en%) and PUFA (4-5 en%) were below the AMDR lower levels of 12 and 8 en%, respectively. For fibre, iron and vitamin D intakes, < 15 % of the children reached the recommended dietary allowances. Everybody exceeded the tolerable upper intake levels for sodium. Although diets in Belgian children were adequate in most nutrients, the implications of low iron, vitamin D and fibre intakes should be investigated. Furthermore, this affluent diet, characterised by SFA, MUFA and PUFA intakes differing from the recommendations and excessive sodium intakes, might increase the risk for CVD in later life.

摘要

这项横断面研究的目的是采用多阶段整群抽样法,调查比利时弗拉芒地区学龄前儿童的能量和营养素摄入量。通过家长报告的3天估计饮食记录,对661名2.5至6.5岁儿童(338名男孩;323名女孩)的饮食进行了评估。将其日常能量和营养素摄入量与国家和国际建议进行了比较。采用统计模型来考虑个体内部的差异。4岁以下儿童的平均每日能量摄入量(男孩为6543千焦;女孩为5757千焦)接近估计能量需求(EER)(男孩为6040千焦;女孩为5798千焦)。对于至少4岁的儿童,平均能量摄入量(男孩为6408千焦;女孩为5914千焦)分别低于EER的6995和6740千焦/天。来自饱和脂肪酸(SFA)的平均能量百分比(en%)(13 - 14 en%)高于可接受的宏量营养素分布范围(AMDR)的上限12 en%。来自单不饱和脂肪酸(MUFA)(10 - 11 en%)和多不饱和脂肪酸(PUFA)(4 - 5 en%)的平均百分比分别低于AMDR的下限12 en%和8 en%。对于纤维、铁和维生素D的摄入量,不到15%的儿童达到了推荐膳食摄入量。所有人都超过了钠的可耐受最高摄入量。尽管比利时儿童的饮食在大多数营养素方面是充足的,但缺铁、维生素D和纤维摄入量低的影响仍应进行调查。此外,这种以SFA、MUFA和PUFA摄入量与建议不同且钠摄入过量为特征的丰富饮食,可能会增加日后患心血管疾病的风险。
